[00:37:02] ModusPwnens: cnk: Yeah, i know. I'm trying that but it's not working properly. I'm printing screenshots and the viewport doesn't seem to change either.
[00:37:39] cnk: even if you sleep to give it time ?
[00:37:59] ModusPwnens: cnk: sleeping doesn't help. However, printing a screenshot does, for some strange reason

[00:38:52] AntiSpamMeta: has joined #RubyOnRails
[00:38:55] baweaver: Not sure how in the world this one happened. So it appears that we had merge conflicts on the db/schema at some point and branch migrations made it into the master db/schema or certain ones were lost in the aether. How would one hunt down orphaned migrations like that?
[00:39:13] baweaver: Nasty piece of work for sure, still looking through git branches for anything with a migration in it...
[00:39:36] baweaver: also, would GUID be recommended over Date timestamps for migrations?
[00:41:24] uglybandersnatch: has joined #RubyOnRails
[00:41:58] cnk: baweaver: so do you have a database with the schema you actually want?
[00:42:19] baweaver: dump the schema from there?
[00:42:35] baweaver: would like to, but I need the migrations to match up
[00:42:36] cnk: if so you could do a schema dump and compare with the dump you get from a clean db + migrations - and then just make the migrations that would match
[00:42:49] baweaver: yeah, which'll be a trip for sure.
[00:43:03] baweaver: but still, possible is better than hopelessly broken.
[00:43:34] cnk: Right - and for most things, code is just to support the greater god of correct data so, bow to the db and move on

[01:21:37] ModusPwnens: bronson: Actually, i figured out the problem.
[01:21:45] bronson: oh good, what was it?
[01:23:30] ModusPwnens: bronson: It's because I needed more 'expect' calls to wait for things. I only had an expect for the original page load as well as the elements that I was waiting to be inserted on the page.
[01:23:48] bronson: ah, that makes sense. glad it was easy.
[01:24:04] ModusPwnens: bronson: However, on page load, I'm populating a hidden div with prefetched results that I insert into the DOM when the user scrolls to the bottom, and I was not waiting for that to happen
[01:24:23] ModusPwnens: bronson: so the headless browser was scrolling to the bottom of the page before there was anything ready to actually append to the list of items.
[01:30:11] cnk: ModusPwnens: Ahh so in a way your test was giving you the right answer - just not your expected answer
[01:31:48] ModusPwnens: cnk: Yep. It was doing exactly what it was supposed to. My assumptions were wrong. If I only had a dollar for every time that happened...

[02:12:44] greghoggard: Hi, im having a little trouble with one of my controllers in my rails app. I recently upgraded from 3.2 to 4.0 and everything seems to be working fine except for when I try edit or destroy a record in my database. For some reason the app is now assigning the name as the id and the controller is not able to find the corresponding record
[02:12:47] makerops: has joined #RubyOnRails
[02:12:49] greghoggard: any help greatly appreciat
[02:15:19] bronson: greghoggard: you could try manipulating your models from the console.
[02:15:22] greghoggard: https://gist.github.com/anonymous/628817be243d38ea7d06
[02:15:29] greghoggard: sorry forgot to post the gist
[02:15:40] trosborn: has joined #RubyOnRails
[02:16:02] bronson: greghoggard: um... isn't that the whole point of friendly_id?
[02:16:27] sevenseacat: I'd be looking closely at friendly_id
[02:16:45] sevenseacat: as it appears to not be doing what you expect
[02:17:17] boontdustie: has joined #RubyOnRails
[02:17:36] havenwood: disagreeable_id
[02:18:45] tjbiddle: has joined #RubyOnRails
[02:18:46] makerops: greghoggard, did you resave the record?
[02:20:46] greghoggard: NoMethodError at /parents
[02:20:46] greghoggard: undefined method `each' for #<ActiveRecord::QueryMethods::WhereChain:0x007fbce8518900>
[02:20:48] greghoggard: i also forgot that it wont let me save new records.
[02:21:02] greghoggard: - @parents.each do |parent|
[02:21:02] greghoggard: = content_tag_for :li, parent do
[02:21:06] greghoggard: %h4= link_to parent.name, parent_path(parent)
[02:21:08] greghoggard: %h6= link_to "Click for more information", parent_path(parent)
[02:21:14] sevenseacat: !gist don't spam the channel!
[02:21:14] helpa: http://gist.github.com - Put your codes online with pretty syntax highlighting and the ability to embed it into other pages.
[02:21:52] tjbiddle: Anyone here using DatabaseCleaner and seeding their database prior? It seems to work; and isn't re-seeding every time (I believe so at least - as grabbing the last record of some seeded models always has the same ID) - but it's insanely slow! https://gist.github.com/thomasbiddle/626c1e458d2bd1ce132a
[02:22:10] tjbiddle: I just don't see why it'd be so slow apart from maybe an extra 5 seconds on the initial load - but every individual test is running slower
[02:22:52] tjbiddle: @greghoggard How are you getting @parents? Unfamiliar with WhereChain
[02:23:09] sevenseacat: http://sevenseacat.net/2015/02/01/use_database_cleaners_deletion_strategy.html seems relevant
[02:23:27] greghoggard: they are defined in my parents controller

[02:24:53] DoctorMonocular: has joined #RubyOnRails
[02:25:04] tjbiddle: greghoggard: Yes, but how
[02:26:17] baweaver: has joined #RubyOnRails
[02:26:20] tjbiddle: @greghoggard http://stackoverflow.com/questions/29887829/how-to-convert-activerecordquerymethodswherechain-to-activerecord-relation
[02:26:26] greghoggard: i changed the find(:all) to where() because i saw a deprecation notice and that ruined it
[02:26:37] tjbiddle: WhereChain doesn't have an each method - you want relation. So however you're getting @parents should be changed
[02:26:43] greghoggard: thank you @tjbiddle
[02:26:55] greghoggard: that makes sense
[02:26:58] sevenseacat: well to be fair find(:all) fell out of fashion about five years ago
[02:27:00] greghoggard: thank you again
[02:27:16] greghoggard: what should i replace find(:all) with?
[02:27:18] sevenseacat: actually, longer now
[02:27:37] Radar: greghoggard: "all"
[02:27:43] sevenseacat: either `all` or nothing
[02:27:47] sevenseacat: depending on the rest of the line
[02:27:53] Radar: Yeah, depends on the ... I'll let sevenseacat talk
[02:28:09] tjbiddle: sevenseacat: No luck =\ Still insanely slow
[02:28:21] boontdustie: has joined #RubyOnRails
[02:28:22] sevenseacat: tjbiddle: define "insanely slow"
[02:28:46] norc_: has joined #RubyOnRails
[02:30:03] tjbiddle: sevenseacat: Just running my models (Which are the lightest part of my test suite, very short currently and about 1/8th of the test count as well) - With seeds: 41 seconds, without: 1.11seconds
[02:30:16] sevenseacat: so the seeds are the slow part, not the db cleaner?
[02:30:31] tjbiddle: sevenseacat: Correct - But I don't know why. Shouldn't it only add to the initial first few seconds?
[02:30:38] tjbiddle: If I run them by hand it probably takes 3 seconds to load
[02:30:41] Radar: Are you running the seeds per test?
[02:30:48] tjbiddle: @Radar before(:suite)
[02:30:53] tjbiddle: https://gist.github.com/thomasbiddle/626c1e458d2bd1ce132a
[02:31:03] sevenseacat: so whats in these seeds?
[02:31:16] sevenseacat: because it apparently takes 40 seconds
[02:31:17] tjbiddle: sevenseacat: Loading 216 records of a single model, that has one column
[02:31:28] pawnbox: has joined #RubyOnRails
[02:31:35] tjbiddle: sevenseacat: rake db:seed 2.94s user 0.81s system 95% cpu 3.912 total
[02:32:01] tjbiddle: sevenseacat: Because I have other records that use them as a relation; I can't think of another design that would do better
[02:32:05] Radar: tjbiddle: anything standing out in test.log? Like long queries?
[02:32:41] matthewd: tjbiddle: Time when running a single test?
[02:33:00] rattatmatt: has joined #RubyOnRails
[02:33:38] tjbiddle: Okay - I think I see it
[02:34:05] tjbiddle: When I create a certain record, I have it create 2 records for each of this other model that's referenced
[02:34:25] tjbiddle: I'll see what I can do to optimize it; so guess the seeds and dbcleaner are working right - just false flag on my bad design :)
[02:34:37] tjbiddle: Thanks guys @Radar - test.log was key on that one ;)
[02:34:52] tjbiddle: Will add it to my notes; hadn't even though about logs for tests
[02:37:20] chouhoulis: has joined #RubyOnRails
[02:37:43] tjbiddle: If I could gather some design advice: I have 2 records being created when a user is created - Basically example records so the user can delete/edit or just create new ones in addition - but so that they aren't seeing an empty selection when they first start. Would there be a better way to go about this?
[02:38:44] sevenseacat: not enough info to say, for me
[02:38:49] Radar: same here

[02:50:28] hnanon: has joined #RubyOnRails
[02:50:39] tjbiddle: So there are "Services" that the user can create that they say they offer. These services have a title and description. They can have as many of these as they way want. When the user is created, I create two of these automatically as a placeholder so when they go to /services they see them - and it gives them a bit of a feel for what they can do with the application.
[02:51:01] uglybandersnatch: has joined #RubyOnRails
[02:51:21] hnanon: If I have a blog post that I want to classify as article, video, audio, etc, what do you suggest as an attribute instead of "type," Category is already used for something else.
[02:53:27] baweaver: has joined #RubyOnRails
[02:53:39] boontdustie: has joined #RubyOnRails
[02:55:51] sevenseacat: tjbiddle: sounds like seed data.
[02:56:09] tjbiddle: sevenseacat: The record belongs to the user though; user's are created dynamically
[02:56:16] techsethi: has joined #RubyOnRails
[02:56:59] sevenseacat: okay, so you create two records when you create a user record
[02:57:00] tjbiddle: hnanon: Classification sounds good
[02:57:01] tjbiddle: https://www.google.com/search?q=synonym+category&gws_rd=ssl
[02:57:02] sevenseacat: whats the issue?
[02:57:09] Devalo: has joined #RubyOnRails
[02:57:27] tjbiddle: sevenseacat: I don't know if there is an issue; that's why I was asking for design advice :) Wasn't sure if that was a messy way or not
[02:57:49] tjbiddle: hnanon: Also, may be a case for polymorphic association.
[02:57:50] delgiudices: I want to render 3 products per row in a products page
[02:58:08] delgiudices: I want to do something like <% products.each3 do |product %>
[02:58:21] sevenseacat: delgiudices: in_groups_of might be your friend
[02:58:32] tjbiddle: delgiudices: http://railscasts.com/episodes/28-in-groups-of
[02:58:37] delgiudices: tjbiddle thanks
[02:58:51] tjbiddle: sevenseacat: Beat me to it :p
[02:58:59] hnanon: Rail is so awesome. I never knew about in_groups_of either.
[02:59:24] hnanon: It's so well thought-out.

[03:01:11] pawnbox: has joined #RubyOnRails
[03:01:21] delgiudices: So how am i supposed to know about these kinds of stuff
[03:01:30] delgiudices: Should i read the entire documentation before developing an app?
[03:01:43] delgiudices: In order to avoid reinventing the wheel

[03:02:06] DmitryBochkarev: has joined #RubyOnRails
[03:02:24] tjbiddle: delgiudices: I didn't know about in-groups-of until you asked
[03:02:29] tjbiddle: Took me about 10 seconds to Google
[03:02:40] delgiudices: i tried googling and didn't find
[03:02:45] delgiudices: So how did yo ugoogle it
[03:02:48] tjbiddle: Just need to know the right kinds of keywords
[03:03:08] delgiudices: Yes so how did you google it
[03:03:29] tjbiddle: delgiudices: https://www.google.com/search?q=rails+each+3&gws_rd=ssl was my first one https://www.google.com/search?q=rails+each+in+groups+of&gws_rd=ssl was my second
[03:03:33] sevenseacat: there's no shame in asking people if you can't find things in google
[03:03:36] tjbiddle: Both of which lead me to in-groups-of
[03:03:42] tjbiddle: Yeah, no shame
[03:03:52] rattatmatt: has joined #RubyOnRails
[03:03:59] sevenseacat: I probably only knew about it becuase I've seen someone ask the question before
[03:04:00] tjbiddle: I'm just saying - You don't need to read the entire documentation (Although totally useful if you spend extra time on it)
[03:04:00] boontdustie: has joined #RubyOnRails
[03:04:04] delgiudices: Yeah i know i just want to improve my googling skills
[03:04:13] delgiudices: But you actually googled in groups of
[03:04:33] tjbiddle: delgiudices: Got lucky on that one that it matches
[03:04:40] tjbiddle: You said 3 per page - my immediate thought was a group
[03:04:48] tjbiddle: Couldn't think of another word
[03:04:49] tjbiddle: Let's try collection
[03:05:12] _Tariq: has joined #RubyOnRails
[03:05:33] sevenseacat: there is shame in asking people if you can't be bothered to google first (IMO), but that's not the case here
[03:05:35] tjbiddle: delgiudices: https://www.google.com/search?q=rails+each+collection&gws_rd=ssl#q=rails+each+collection+at+a+time lead me to it
[03:05:51] westoque: has joined #RubyOnRails
[03:06:11] tjbiddle: Yeah - definitely no harm in asking. Just in your googling try to think of different ways to phrase a question. A lot of the time my first few attempts are terrible wording, but then I'll learn of some terminology along the way
[03:06:19] tjbiddle: And then I'll throw that in the search - and then winnner

[03:37:33] jottr: So, I have this annoyingly slow query, which takes ~60 seconds to complete, generating a timeout on heroku. I've been trying to improve it, by adding includes() to the query. That improved the query a little bit: https://git.io/vaepv

[03:43:00] jottr: Wish.find(43).users is especially slow, since it iterates over all the users. I have no hunch how I could improve the query speed. Maybe someone in here has a few pointers?
[03:43:21] sevenseacat: iterating seems bad
[03:44:27] sevenseacat: does wish 43 have 2538 users or just one?
[03:44:37] sevenseacat: are you actually rendering a json feed for 2538 users?
[03:44:52] jottr: to all the above
[03:45:22] Sigma00: jottr: sounds like you're missing indexes on your table
[03:45:27] sevenseacat: I think you might want something like Wish.includes(users: [:chances, :payments]).find(43)
[03:45:36] sevenseacat: payment sorry, not payment
[03:45:58] sevenseacat: oh right I missed the .first in the second query
[03:46:06] Arcaire: Have you tried just
[03:46:15] Arcaire: But for real I'm with Sigma00 here.
[03:46:22] sneakerhax: has joined #RubyOnRails

[03:57:22] sevenseacat: where it is there is fine

[04:02:24] sevenseacat: what queries are being run now?

[04:19:13] jottr: ^ Wish.includes(users: [:chances, :payment]).find(params[:id]).users.order(avatar: :desc) is the query I now use in the controller.

[04:31:00] jottr: What it is doing seems to not necessarily correlate with what it should be doing...
[04:31:05] matthewd: The danger there is normally some more subtle spelling of Model.includes(:foo).load.order(:bar).each -- order gives you a new relation, so bye-bye loaded data
[04:31:30] sevenseacat: I think thats exactly whats happened
[04:31:31] matthewd: Or similar-but-differently, Model.includes(:foo).each {|m| m.foo.where(true) }
[04:31:40] sevenseacat: jottr: wanted to eager load users, and then order them also
[04:31:55] matthewd: Should be fine as long as the load doesn't happen early
[04:32:32] sevenseacat: oh so maybe order(users: [:avatar]).users instead of users.order(:avatar) ?
[04:32:38] matthewd: jottr: No to_json methods defined?
[04:33:01] Radar: just use mongo

[04:35:59] jottr: I've tried with Wish.includes(users: [:chances, :payment, :wishes]).find(params[:id]).users.order(avatar: :desc)
[04:36:08] jottr: ...which made it even slower.
[04:36:23] matthewd: Am I completely misremembering the default AR#to_json behaviour? I thought it included attributes but not associations
[04:37:00] sevenseacat: I don't think I've ever used the default behaviour, so i have no idea
[04:38:09] matthewd: If it automatically included associations, you'd get a big infinitely recursive mess, surely
[04:38:56] matthewd: jottr: Can you please `User.first.to_json` in a console?

[04:51:26] matthewd: Yeah, so https://github.com/jottr/meingrundeinkommen/blob/develop/app/serializers/user_serializer.rb#L30 is an instance of the second bad example I showed
[04:52:02] matthewd: The order breaks the includes, because we can't apply the order to the already-loaded-at-that-point data; we have no choice but to re-query

[05:56:04] arup_r: so now what wrong you see in this outcome ?
[05:56:07] tjbiddle: arup_r: Doesn't seem to be doing that. When you say type - is that a specific attribute?
[05:56:26] arup_r: without that column, STI is incomplete

[05:58:13] tjbiddle: arup_r: That's funny. I originally had "type" in my table completely by coincidence; and I was wondering why it was saving as the Class name. So I changed it to something else.

[08:34:02] tjbiddle: I have an STI relation for 3 of my models. They're used in a cascading way, so if C has a value, then B and A are ignored. But if C does not have a value it will fall back to B, if B doesn't - then it falls to A (Which always does). I'm doing this this way: https://gist.github.com/thomasbiddle/1c6038bc6fbfc2bed400
[08:34:50] tjbiddle: However it ends up making ~5 different SELECT statements this way. Is there a pattern that would follow this already in place to get this down?
[08:35:07] rvanlieshout: in like 105% of the cases i've seen people use STI they would be better of not using it
[08:35:22] tjbiddle: rvanlieshout: It's actually cleaned up my code quite a bit

[08:41:28] rvanlieshout: moving back will eventually save you more time :)
[08:42:13] tjbiddle: rvanlieshout: Hopefully :) I am checking though - I'm seeing some reasons not to use STI on one part of my app; but the one I mentioned I'm not so sure. The one mentioned above all share the exact same columns (Price & duration) and will *always* stay in sync
[08:42:30] tjbiddle: They're basically ways to scope down to more specific settings; but the settings will never have different options
[08:43:18] tjbiddle: The other thing I have definitely should be changed from STI though I think; I'll check into that later though
[08:43:34] rvanlieshout: tjbiddle: and even then, why is it bad to have multiple tables?

[08:45:32] tjbiddle: I'll play around with it. Thanks for reminding me of Concerns :)
[08:47:32] rvanlieshout: :) do that! maintaining multiple tables is way way way easier then STI

[08:49:15] alfie_max15: i'm using a query like this : User.select("DISTINCT ON (email, domain, ip_address) *")
[08:49:41] alfie_max15: how should i index my fields so that this query wont be so expensive in the long run
[08:50:04] rvanlieshout: add an index for those 3 columns?
[08:50:17] rvanlieshout: also you could just make sure the set is unique using a validation
[08:50:27] rvanlieshout: and prevent double entries in the db. then you don't have to distict it on query
[08:50:50] alfie_max15: i dont want them to be uniq
[08:51:18] rvanlieshout: then why distinct them?
[08:51:18] sevenseacat: then what do you want returned? >_>
[08:51:23] alfie_max15: but i would also want to get the count and show in in the index, which is still something i dont know what to do
[08:51:36] gr3yR0n1n: has joined #RubyOnRails
[08:51:47] alfie_max15: sevenseacat, hope you get the idea
[08:51:55] rvanlieshout: the count of what?
[08:53:42] alfie_max15: there can be many users with the same email + domain + ip, so i want to list them in a table, (for which i use distinct)
[08:54:03] rvanlieshout: why would you want to list them unique if you don't want them to be unique?
[08:54:05] alfie_max15: and in the table i want a column which shows the count of that user based on email, ip, domain
[08:54:34] rvanlieshout: make a query that returns 4 values, email, domain, ip-address and count(*)
[08:54:36] rvanlieshout: User.pluck that
[08:54:36] alfie_max15: instead of showing duplicate entries i would show the count
[08:54:37] rvanlieshout: use the array
[08:55:42] alfie_max15: could you help me out with that, plucking the three fields is fine, but what about count? (no idea about that)
[08:56:23] arup_r1: alfie_max15: seems like you want group by
[08:57:11] arup_r: "there can be many users with the same email + domain + ip, so i want to list them in a table," ... if so, group by and then count the result in each group will do it..
[08:57:27] arup_r: with distinct on, you can't take the count
[08:57:48] alfie_max15: let me try that
[08:58:15] rvanlieshout: alfie_max15: User.group('email, domain, ip_address').pluck('email, domain, ip_address, COUNT(*)')
[08:58:18] tetraktys: has joined #RubyOnRails
[08:58:24] arup_r: alfie_max15: ^^
[08:58:24] rvanlieshout: don't count them in ruby
[08:58:27] rvanlieshout: that would be slow :)
[08:58:36] rvanlieshout: and, add an index on the users table for those 3 columns
[08:58:38] arup_r: ready made solution.. provided by rvanlieshout :)
[08:58:39] nocontrol: has joined #RubyOnRails
[08:59:39] arup_r: rvanlieshout: one question, why are you interested to get an Array, instead of AR wrapper object around them, as we get when we `.select`?
[08:59:54] nocontrol: I am running a simple post/create controller test with rails embedded test engine and it fails simply with "didn't change by 1" or "expected 2, got 1". Is there any chance I may get more information ? This doesn' help at all
[09:00:25] alfie_max15: rvanlieshout, yeah, having an array wont work, as i want it to be an AR object
[09:00:27] arup_r: nocontrol: yes, use a Gist, add test code and exception there
[09:00:31] finnnnnnnnnnn: has joined #RubyOnRails
[09:00:51] rvanlieshout: arup_r: because the count isn't part of the model and you just want to present a list. no need to create objects in memory for them
[09:00:51] nocontrol: arup_r: can I get a more verbose output ? I tried with --verbose but nothing changed
[09:01:28] rvanlieshout: alfie_max15: why?
[09:01:48] arup_r: because he want to iterate over in view?
[09:02:21] rvanlieshout: and you're unable to iterate over an array?
[09:02:46] johnflux: has joined #RubyOnRails
[09:02:52] arup_r: doesn't look good as it does while iterating over an AR.. hehe..
[09:03:21] rvanlieshout: it's just an .each
[09:03:22] arup_r: anyway, in this case I might use `.select` .. not liking `.pluck`.. but that's me.
[09:03:30] alfie_max15: yeah, is there a way i can get AR objects instead
[09:03:31] rvanlieshout: select makes it slower :) but hey
[09:04:01] arup_r: alfie_max15: just replace the .pluck with .select in rvanlieshout solution...

[09:04:35] rvanlieshout: that won't work
[09:04:36] arup_r: nothing big deal. but I appreciate the explanation of using .pluck .. thanks for that
[09:04:42] alfie_max15: yeah, i tried that
[09:04:49] rvanlieshout: then you'll have to to name them
[09:04:56] arup_r: why.. umm
[09:05:08] rvanlieshout: just use pluck
[09:05:13] pawnbox: has joined #RubyOnRails
[09:05:16] rvanlieshout: or give them a name in your select
[09:05:30] alfie_max15: give them a name in select like?
[09:05:47] arup_r: like COUNT(*) AS user_count
[09:05:54] arup_r: or some good name..
[09:06:08] arup_r: I thought Rails give it for us..
[09:06:35] mrbubbles: has joined #RubyOnRails
[09:06:41] rvanlieshout: really. why not pluck?
[09:07:04] rvanlieshout: it's faster and doesn't require that fictive attribute
[09:07:11] rvanlieshout: als your result isn't a user
[09:07:17] rvanlieshout: it's just the combination of those 3 values
[09:07:22] rvanlieshout: why threat it as a user?
[09:07:22] drptbl: has joined #RubyOnRails
[09:07:34] alfie_max15: well the real reason is that i am using active admin, and i'm trying to write my own scoped_collection
[09:07:49] alfie_max15: so it has to be a AR wrapper object
[09:08:02] arup_r: ah,, game is over.

[09:09:42] rvanlieshout: you might have it in a day, but spend weeks and weeks in trying to add simple stuff
[09:09:51] rvanlieshout: where if you would spend 2 days you would have something extensible
[09:09:51] wldcordeiro: has joined #RubyOnRails
[09:09:54] rvanlieshout: cause an admin panel just isn't that hard
[09:10:15] sevenseacat: lol, active admin

[10:37:09] pawnbox: has joined #RubyOnRails
[10:37:20] EdwardIII: this isn't to do with turbolinks events not firing, it's because when you click 'back' the old page content includes the spinner heh hrm
[10:37:42] Wobni: has joined #RubyOnRails
[10:37:47] EdwardIII: but it doesn't seem to fire 'turbolinks:render' or ':load'
[10:38:02] matthias_: has joined #RubyOnRails

[10:39:35] hahuang61: has joined #RubyOnRails
[10:39:46] finnnnnnnnnnn_: has joined #RubyOnRails
[10:40:12] EdwardIII: it looks a bit like 'turoblinks:load' gets triggered before the reload of the previous page in the buffer has finished? is that possible?
[10:41:45] lxsameer: I have a broken "require" statement in a css manifest in my project, but i didn't use that manifest in my layout, but I get an sprokects::FileNotFound, is that normal ?
[10:42:17] DaniG2k: hmm there might be a bug with the by_star gem
[10:42:28] DaniG2k: regarding my previous comments about failing tests in rspec
[10:42:40] DaniG2k: because @articles.by_section(@section).by_year(year) works fine
[10:42:49] jeanlinux: has joined #RubyOnRails
[10:42:59] DaniG2k: but adding the by_month(12) returns nothing despite having a created date of December
[10:43:45] sevenseacat: so what does by_month do ?
[10:43:48] DaniG2k: im quite sure this is a bug
[10:43:56] EdwardIII: hrm this is confusing heh
[10:44:01] universa1: what does by_month(11) return
[10:44:01] EdwardIII: i've looked at pretty much every event
[10:44:10] DaniG2k: sevenseacat: by_month should just get the articles by month creation date
[10:44:24] sevenseacat: should, or does?
[10:44:25] DaniG2k: universa1 I've tried by_month with every number from 1 to 12 and they all return []
[10:44:33] EdwardIII: turbolinks:before-cache and turbolinks:render both fire when you click 'back', but $('body').remove('.spinner-wrap') does nothing on both
[10:44:54] EdwardIII: i thought if i put it in turbolinks:before-cache that would ensure no page ever gets stored with a spinner in it, but that doesn't work
[10:45:01] DaniG2k: sevenseacat: and I'm looking on github, it seems the normalization.rb for the by_star gem was updated recently

[10:55:03] DaniG2k: universa1: thats interesting....Article.by_month(12, year: 2012) returns the correct result but Article.by_month(12).by_year(2012) does not
[10:55:10] universa1: DaniG2k: first is: in 2012, second is: in december 2016 ...unless you can bend space-time this seems fairly impossible to me.
[10:55:26] DaniG2k: yea deffo a bug

[13:38:40] passick: How do I do that?

[13:41:51] Megamos: has joined #RubyOnRails
[13:42:04] rietta: passick, what do you mean?
[13:42:27] rietta: Specifically by “chantge some information about the event”?
[13:42:38] rietta: Sounds like access control, you can still use something like cancancan for that.
[13:42:40] Detch: has joined #RubyOnRails
[13:44:57] passick: I have two models: Event and Picture, Event has many Pictures. I also have users, and I want them to be able to upload their pictures for events. As far as I understand, when I do a nested resource, I will have to submit pictures through a form for editing the event, but wouldn’t the user then have the ability to modify the information about the event itself?
[13:45:45] rvanlieshout: passick: your nested resource assumption is wrong
[13:45:58] rvanlieshout: you should just create a controller for those pictures
[13:46:10] rvanlieshout: make it a nested resource so you can use /events/123/pictures/new over /pictures/new?event_id=123
[13:46:22] thebastl: has joined #RubyOnRails
[13:46:48] passick: And if I want to be able to upload several new pictures at once?
[13:46:55] rietta: passick, you will have a controller actian that has a event_id along with the :id of the picture (for actions other than index and create)
[13:47:20] aaronr: has joined #RubyOnRails
[13:48:00] rietta: I find it useful to include pry-rails and then throw a binding.pry in the controller create or update controller action. Then inspect the params hash to see what’s there. It becomes clear quickly what magic is going on.

[14:19:58] arup_r: yeah, but that will not work
[14:20:10] arup_r: because last zone will override the first one

[14:54:17] workmad3: delgiudices: sounds like you recently updated rails

[14:54:47] emilkarl: has joined #RubyOnRails
[14:55:08] workmad3: delgiudices: that could also do it... it may not be that anything actually 'changed' in your database, simply that the schema dumper picked up more details from db introspection and reflected them in schema.rb

[15:13:17] chouhoulis: has joined #RubyOnRails
[15:13:31] jhass: hnanon render takes an action name of the same control or a template path, it does not take a route
[15:13:41] jhass: *same controller
[15:14:00] hnanon: What's an example of a template path?
[15:14:13] SteenJobs: hnanon: try redirect_to
[15:14:17] jhass: a path relative to app/views
[15:14:28] jhass: you can also omit the extension of the file
[15:14:40] SteenJobs: unless you explicitly want to render and not redirect
[15:15:06] hnanon: SteenJobs, jhass: Thanks.
[15:15:20] SteenJobs: subtle differences, but different nonetheless
[15:15:33] jhass: not that subtle tbh
[15:17:24] SteenJobs: subtle doesn’t mean not profound
[15:17:42] arup_r: has joined #RubyOnRails
[15:18:01] SteenJobs: just for a lot of people they may mistakenly presume they do very similar things
[15:18:40] arup_r: finnnnnnnnnnn: try this also before_update :do_summat, if: :name_changed?
[15:19:31] finnnnnnnnnnn: arup_r: that works too
[15:20:00] hnanon: jhass: So I tried edit_user_card_path(@user) and I'm getting the same error. Card is a nested resource under users.
[15:20:17] SteenJobs: then you need to pass @card as well
[15:20:26] hnanon: There is no card object.
[15:20:27] SteenJobs: check rake routes and make sure you know what the route expects
[15:20:52] jhass: how is that different from.... nvm I'll bail

[15:21:47] jhass: I had that fun yesterday already
[15:22:03] SteenJobs: hnanon: or did you follow jhass’ rec and change the path youre passing to render?
[15:22:16] hnanon: Template error. I followed jhass' advice.
[15:22:37] hnanon: Previously it was edit_user_path(@user)
[15:22:51] SteenJobs: hnanon: if the controller action that’s being routed to is cards#edit
[15:22:57] sp1rs: has joined #RubyOnRails
[15:23:03] SteenJobs: then you need an edit.html.erb in the cards directory
[15:23:04] n008f4g_: has joined #RubyOnRails
[15:23:15] hnanon: I have one there.
[15:23:46] SteenJobs: then i need to see more code, but humor me and use redirect_to your_path_helper
[15:24:23] jhass: and give up preserving what the user entered previously...
[15:24:58] jhass: that's typically the reason you render instead of redirect
[15:25:04] SteenJobs: but that would be in the update action
[15:25:13] SteenJobs: edit is just presenting a new edit view

[15:25:57] jhass: they try to "render" an edit action

[15:36:25] tubbo: tbh i've found that most of the time, if you're overriding devise's most basic features, you probably don't want to be using devise.

[15:39:31] delgiudices: And why do i have to test the controller if it's being tested in the feature
[15:39:46] SteenJobs: tubbo: haha it’s true. i wonder why i haven’t migrated away from it. more often than not you’re overriding the views, overriding the routing, and very often overriding some controller actions. so there’s not much left...
[15:40:30] tubbo: SteenJobs: see i've had the polar opposite experience, only had to ever override views.
[15:41:11] SteenJobs: tubbo: honestly part of it is really my fault. i could’ve designed things to avoid having to override any controllers by just moving some user attributes to a separate model
[15:41:25] tubbo: delgiudices: they all test different parts of the application logic. your unit tests won't catch issues with user input, your controller tests won't catch rendering problems.
[15:41:46] tubbo: delgiudices: your feature tests will be too slow and "high-level" to be of any use when the issue is deep within your models.
[15:41:52] ace05_: has joined #RubyOnRails
[15:42:13] SteenJobs: tubbo: like i wanted a user bio to be part of the user model, and since the bio was being updated with ajax, i needed to handle the response in the registrations controller. but that could’ve just been abastracted to a separate user_info table or what not
[15:42:14] ferr1: I get json response https://gist.github.com/Fercell/fda15d458532899747bc and how would I turn it into hash so I could work with entries?
[15:42:22] tubbo: SteenJobs: or a Profile :)
[15:42:28] SteenJobs: ferr1: JSON.parse
[15:42:30] tubbo: many people use the User / Profile abstraction for that
[15:43:24] SteenJobs: tubbo: yea was pretty stupid. and then as i added more bio like attributes, i just kept at it..i’m gonna migrate everything to a profile table eventually, when i get the courage to sift thru the db migrations and make sure there are no conflicts
[15:43:47] artto: has joined #RubyOnRails
[15:43:49] tubbo: SteenJobs: i thought there was a method you could override somewhere that let devise deal with more attrs though..

[15:44:01] SteenJobs: tubbo: yea there is
[15:44:08] gbgdev: has joined #RubyOnRails
[15:44:16] SteenJobs: but the attributes are edited in-place on the user profile
[15:44:30] SteenJobs: so it’s a JSON reeq
[15:44:56] SteenJobs: so i needed to squeeze a response into the appropriate controller action
[15:45:59] SteenJobs: tubbo: most things there are straightforward ways to customize, like updating profile w/o password, etc. but with routing, i wanted my login/signup views to be on the same page (using tabs)
[15:48:43] tubbo: well there are two solutions to that problem
[15:48:44] openstruct: has joined #RubyOnRails
[15:48:51] tubbo: #1 - just copy/paste the two forms side by side
[15:48:58] rubyonrailed: has joined #RubyOnRails
[15:48:59] tubbo: #2 - use tabs and request each form via ajax
[15:49:16] tubbo: make sure you have a means of turning off the layout on any XHR request in ApplicationController.

[18:21:54] chridal: tubbo: Cheers. Did you see a hit on your RPM when you started rate limiting in the app?
[18:22:07] SteenJobs: tubbo: i figured it out though…seems like if you create your own custom field it needs to be tied to a model attribute, which was why it wasn’t working for me.

[18:22:31] SteenJobs: tubbo: but then looked through the source code and saw that they have Field::HasMany anyway, which i can use to show the association count, so all good.
[18:22:42] tubbo: chridal: we actually haven't deployed that version of the API yet so i don't know :)
[18:22:53] fox_mulder_cp: tubbo: and what u mean about your administrate using?
[18:23:09] tubbo: fox_mulder_cp: what part of "yes i use administrate" did you not understand?
[18:23:20] tubbo: i know that sounded harsh but i couldn't think of a better way to say it lol
[18:23:22] chridal: tubbo: Will have to have a look at it. Cheers.
[18:23:55] fox_mulder_cp: tubbo: u use it's customizing, or only this default table style views?

[18:24:31] naftilos76: Hi everyone, i am facing an issue with an html a tag: <a style="text-decoration: none; color: white;" href="/lists/home">Home</a> and a js script : window.location.href = '/lists/home/'; The js script is causing a full page reload (js, images etc) but the a tag is (obviously) using turbolinks and the request is the only thing that is receiving a response. How can i get the same behavior using window.location.href ?
[18:24:35] tubbo: fox_mulder_cp: oh, yeah i've just used the table-style views for now. customized the forms pretty heavily.
[18:24:41] tubbo: well, i'm going to at least :D
[18:24:46] Psy-Q: when i save a record in an rspec test and then ask for foo.associated_thing.new_record? i still get "true" despite the associated record seeming to have been saved, and id is nil. when i use pry in the same spot and call foo.save by hand, id is 1 and new_record? is false, the associated record is saved. can i not save associated records and check for them with rspec?
[18:24:47] flashpoint9: has joined #RubyOnRails

[18:26:50] t4nk190: has joined #RubyOnRails
[18:26:53] tubbo: naftilos76: don't use window.location.href, use Turbolinks.visit().
[18:27:01] ModusPwnens: I need to make some async calls in my before(:all) block of an rspec test to setup test data. Would it be bad practice to use capybara expectations in the before block just to use their implicit wait_until functionality?
[18:27:36] naftilos76: tubbo, use Turbolinks.visit() within js? is that a js func?
[18:28:28] tubbo: fox_mulder_cp: yeah, i was actually halfway through creating my own scalable admin implementation, but administrate is effectively what i was building anyway. i just didn't have dashboards.
[18:28:50] tubbo: fox_mulder_cp: so i used administrate because it was already there and did everything i needed to do.
[18:29:25] SteenJobs: tubbo: more like it didn’t do everything you didn’t need it to do :)
[18:29:28] tubbo: fox_mulder_cp: you can see the source of my site at https://github.com/waxpoetic/brotherly

[18:32:19] tubbo: naftilos76: consult the README or other documentation, but it's definitely a method on the Turbolinks object.
[18:32:59] SteenJobs: there should just be an error that says “eff turbolinks” whenever the server senses turbolinks running
[18:33:05] naftilos76: tubbo, Turbolinks is definitely an object , i get that . Let see what i can find. Thanks

[20:48:36] alaing: ciree: I would like it to not include the square brackets or "\"
[20:49:00] ciree: u want, all the values from checkVisible.uniq, to be in actual_result?
[20:49:39] alaing: so it should be "should" or "should not, should"

[21:03:05] SteenJobs: Radar: i was going to but just realized it won’t matter, it’s not a rails thing - the post req is being placed from Parse cloud code, and even the response there is messed up JSON, and the entire second tier in the JSON response is a string for some reason. i presume it’s a parse issue so i’m gonna look into it now that i’ve isolated it.

[21:09:32] siaW: any gem for that?
[21:09:37] Radar: rattatmatt: I think an events table with STI would be fine.

Is there a better way to get this b

[21:29:43] Hates_: cabinB: ahhh, that makes things complicated then
[21:29:54] Hates_: cabinB: their docs say you can use phpmyadmin
[21:29:57] aaronang: arup_r: By the way, we chose Rails ;)
[21:30:01] cabinB: Hates_, yeah i know :-/
[21:30:09] fox_mulder_cp: cabinB: yes. use system wide phpadmin, if u want use mysql or pgadmin even pgsql

[21:33:06] aaronang: Well, arup_r you are right, we actually ask you guys. So for our course we are required to demonstrate that we are able to contribute to Rails. We did some documentation-related contributions but would really like to do some more challenging tasks.

[21:34:58] aaronang: Hates_: Although it is strange, we really like it :)
[21:35:03] Hates_: aaronang: well you can start with the rails issue list :) https://github.com/rails/rails/issues
[21:35:39] aaronang: Hates_: We already had a look at it but it is kind of difficult for us to estimate what is actually doable in one week (note, we cannot spend one week full time)
[21:36:01] aaronang: Hates_: Thanks for your suggestion though :)

[21:49:00] tubbo: aaronang: have you considered analyzing a project that was a little smaller than rails?
