[10:00:04] crst: Hi, I have a general question. What issues do you most often run-in with rails's implementation of MVC?

[10:35:09] crst: Hi, I have a custom env staging and staging.log is created but the file is always 0KB. config.log_level = :warn I have the suspicion that it just doesn't log anything.
[10:40:11] crst: wbednarski: that works. I don't suspect a permission issue, the same user can run production and dev and the logs are created.
[10:40:32] crst: created and filled with data
[10:40:48] crst: on staging it's just created and keeps 0KB

[10:17:01] crst: dionysus69: ok, thank you
[10:39:36] crst: dionysus69: In that context the same could be achieved with cancancan (which is already implemented), right?

[12:26:56] crst: Hi, is there anything one needs to be aware of when upgrading from 5.1.5 -> 5.2 ?
[12:28:29] crst: *anything special
[12:51:00] crst: Is there a particular reason rspec is not included in "rails new" (v5.2 at least)?
[12:53:27] crst: May I ask how you prefer testing?
[12:54:24] crst: that's a relief
[13:14:13] crst: dminuoso: I've never used minitest
[13:15:01] crst: Also I'm, not much into rspec either, but I assigned writing tests in rspec recently.

[21:03:51] crst: Hi, when I run Model.where(status: 'paid').each {|f| f.calculate_total_price } in console it stops during the process but doesn't show me the error. How can I see what caused the interruption?
[21:31:10] crst: havenwood: oh yeah, indeed. it finishes through everything and is super fast. Unfortunately the results aren't stored in the db. http://dpaste.com/1495XS6
[21:36:10] crst: havenwood: wow the find_each is so much better. What does OOM mean? At the moment it does not make sense to me why it's not saving, honestly.
[21:36:48] crst: that makes sense. it's a couple of thousand records
[21:41:29] crst: Is it replaced by FREE?
[21:45:40] crst: havenwood: a little better FREE though :D
[21:47:49] crst: havenwood: Thanks so much for the explanation. I commented out the before_save and ran it again. Can you tell me if it is supposed to work then? I'm asking because it seems all fields were emptied by the calculation.
[22:32:02] crst: havenwood: Thanks man! I did this and it works now: Model.where(status: 'paid').find_each {|f| f.calculate_total_price; f.save }
[22:44:21] crst: havenwood: hmm that's strange, when I use .find_each(&:calculate_total_price) instead nothing gets updated.

[17:38:41] crst: Hi, I'm trying to upgrade 4.2 -> 5.1. Added gem 'rails', '5.1.5'. But when I run bundle update rails I get: The bundle currently has rails locked at 4.2.10. Try running `bundle update rails`
[17:39:49] crst: mroutis: It's a loop
[17:43:42] crst: mroutis: It's so strange, isn't it? I've been avoiding deleting Gemfile.lock since I run into multiple issues when I did.
[17:45:27] crst: yep, rbenv
[17:50:25] crst: Maybe it's because some gems link to github directly
[17:53:34] crst: lol, now when I bundle install after removal of Gemfile.lock I get: Could not find gem 'rails (= 5.1.5)' in any of the gem sources listed in your Gemfile.
[17:55:22] crst: mroutis: This is the Gemfile: https://bpaste.net/show/f16ba897aeec
[18:01:38] crst: wait, I've got it. It's been either rbenv-bundle-exec or rbenv-binstubs which caused that. Good riddance.

[07:55:19] crst: Good Morning
[16:16:53] crst: Any idea how one can make the following with chartkick: There's a table bills, each record has a number value and a date. Now I'd like to group the x-axis my month (or else) and show the number values on the y-axis. (I'm actually trying to create a profit over time chart)
[16:33:28] crst: Or any idea how one can generate the following data set for chartkick with activerecord: There's a table `bills`, each record has a number value and a date. Whenever some records share the same day, week, month (depending on range) the number values will be summed up.
[16:50:03] crst: Exuma: thanks! This needs to be encapsulated, right?
[16:50:46] crst: In something which injects @start_date and @end_date to get the range
[16:53:38] crst: According to the first example at https://www.chartkick.com why can't one just do something like <%= line_chart Bill.amount.group_by_day(:created_at).count %> ?
[16:55:07] crst: dminuoso: I can't. I get: undefined method `amount'
[16:55:58] crst: And apart from that I have no idea how to make something better or why it's considered bad.
[16:57:15] crst: dminuoso: It has, when doing `Bill.last.amount` I get the value
[17:02:37] crst: dminuoso: Please give me another hint
[17:04:10] crst: dminuoso: Do you have an idea what Bill.group_by(...) is supposed to do?

[10:50:09] crst: Hi, what can you do when the main script is in the head but js only works when it's after certain dom elements? The snippet is already inside $(document).ready
[10:52:16] crst: tbuehlmann: yep
[10:53:35] crst: not in this project, no
[10:56:39] crst: tbuehlmann: for one this: https://bpaste.net/show/2f025c392326
[10:57:42] crst: I have the suspicion the issue relates to the external scripts
[11:01:29] crst: This is from the view: https://bpaste.net/show/f0643099adb5 When my js is inside the <script> tag here it works
[11:02:05] crst: Strange, console says: Uncaught ReferenceError: jQuery is not defined
[11:02:32] crst: But it certainly is included
[11:04:35] crst: tbuehlmann: https://bpaste.net/show/7b7c377d0cae
[11:08:13] crst: dminuoso: I'm having huge latency when using webpacker at least in a certain app. Might this be related to your issue?
[11:11:19] crst: dminuoso: loading, reloading, and ajax takes a couple of seconds
[11:13:05] crst: dminuoso: yep
[11:26:45] crst: dminuoso: Loading a request feels way longer than the time the profiler gives me. It seems like the profiler gives me the time the page usually loads without webpacker installed.
[11:27:21] crst: chrome gives me 35s profiler gives me 1.5s
[11:32:32] crst: dminuoso: 0.18ms according to chrome. Where can I find the Middleware stack infos that you need? I'm sorry no pro here.
[11:38:37] crst: dminuoso: I can only tell of development. Even a fresh webpacker:install without adding anything to the views is enough to trigger the latency. "Error: Command 'middleware' not recognized"
[11:39:06] crst: rails is 4.2 in this case btw
[11:39:30] crst: I need to rake, one sec
[11:40:37] crst: dminuoso: https://bpaste.net/show/a9d01a6645bd
[12:34:27] crst: dminuoso: Unfortunately not, I signed an NDA and can't reproduce the issue. Thanks anyway!
[12:39:01] crst: All right thanks. It might take me a couple of days/weeks to find the time for this.
[12:39:42] crst: There's also an upgrade to 5 planned and maybe that'll resolve the issue
[12:52:43] crst: dminuoso: Absolutely. Atm the webpack issue isn't high priority though :)
[13:05:13] crst: at the moment
[13:06:11] crst: fox_mulder_cp: gem install ud; ud atm :)

[13:16:29] crst: Hi, this looks really strange to me. Does it make sense? supplier_fuel_price * (invoice_order_amount || order_amount)
[13:17:08] crst: Xeago: logic
[13:18:14] crst: lol, that's a great comment actually
[13:18:41] crst: it calcultes records ind a db table
[13:18:58] crst: what if both are present? or both are null
[13:25:49] crst: dminuoso: thanks for the explanation, it makes more sense to me now
[13:27:19] crst: canton7 ^
[13:34:46] crst: dminuoso: There's not much reliability on the new project I'm working on. It's a mess to be honest and needs a big cleaning.
[13:36:18] crst: I have been working with laravel for last couple of months. Really happy working with rails again, though laravel is really ok
[13:47:09] crst: an idea why?
[13:47:09] crst: Hi, I'm using 'ajax-datatables-rails' and in the records.map do |record| there's buying_cost: record.supplier_fuel_total_price which relies on def supplier_fuel_total_price; supplier_fuel_price * (invoice_order_amount || order_amount); end This particular columns is not sortable on click when I have buying_cost: { source: "FuelQuote.supplier_fuel_total_price" }, in view_columns Anybody
[13:55:49] crst: Mhm, maybe it's because I'm getting => #<Money fractional:2934558.0 currency:USD> for FuelQuote.first.supplier_fuel_total_price
[19:54:34] crst: What is the terminology of having a method in the model file like this: `def test; "AAA" ;end` what gives: `Model.last.test => "AAA"`
[20:02:12] crst: Ah ok, thanks. I can call the instance method this way and get a result in the console, but when I use ajax-datatables-rails I get: PG::UndefinedColumn ERROR: column Model.test does not exist I think that's because it's not really a column of the model. Is there a way to attach the instance method that it behaves like a virtual column?
[20:05:40] crst: My current query is like this: Model.includes(:client_company).where(status: 'paid').references(:client_company).distinct

[15:03:13] crst: Hey guys! chrisfix here. :) Why is /usr/local/var/rbenv/shims always on top of my paths? It messes around with normal binaries which I can't use properly then.
[15:46:39] crst: havenwood: that's right. I'm using rbenv to manage my ruby versions and like to keep using it. But when I want to use rg -irl 'active' . for instance it interferes with redgreen-1.2.2/bin/rg That's just one example of a handful
[15:48:13] crst: havenwood: exactly
[15:51:23] crst: havenwood: yeah, for this reason I keep my main installation path /usr/local/bin on top of all other paths, but then rbenv forces it's shims on top of that. I manage my paths pretty well but once in a while rbenv interferes and I'd like to use paste commands or use history and avoid aliasing the command.
[15:52:21] crst: havenwood: I know, but then I'd have to do that each time :)
[15:55:19] crst: havenwood: ok, thanks a lot! matthewd: I'm fairly certain it is required by at least one rails project I'm working on. havenwood: There are some gems I use often in the cli and like to avoid renaming them, too.
[15:59:34] crst: havenwood, matthewd: I see, thanks for suggesting me these possibilities! I keep these in mind while trying to create a workaround.

[06:33:33] crst: tamouse__: I'm sorry, I don't understand what you're saying. What does that mean?
[06:38:59] crst: I see. So I can use value: "anything" unless @book.perstited?
[06:39:35] crst: tamouse__: perfect, thank you!
[06:42:15] crst: tamouse__: yeah, it does that automatically for edit

[13:23:00] crst: Hi, how can I make this work? = f.submit (current_page?(user_path) ? : "t" : "f")
[13:27:28] crst: dminuoso: it should give either f.submit "t" or f.submit "f"
[13:30:12] crst: maybe this is better, i tried so much already: f.submit current_page?(user_path) ? "t" : "f"
[13:32:45] crst: oh, it does work now...
[13:32:51] crst: thanks :)
[13:35:20] crst: dminuoso: how is your lambda calculus going?
[13:37:08] crst: cool, keep up the good work :)
