[17:17:31] amperry: Hey folks, in a 'respond_to' block in my properties controller, I have in the 'else' clause the following: "format.html { redirect_to [:admin, @property], alert: 'property was not updated.' }". I'm hoping to get that to redirect to '/admin/properties/edit/'. But if there's an error updating, I only get the error "No template found for Admin::PropertiesController#update, rendering head :no_content".
[17:18:08] amperry: Why should that be? I'm not trying to go to update, I'm trying to go to edit.

[18:15:56] amperry: Hey folks, I've got a select input that maps to an ActiveRecord relation supers, defined as: "@supers = User.where(role: :supervisor) || {}". I put the '|| {}' to avoid a NoMethodError when the results are empty, but is there a more ActiveRecord/Rails-ish way to do that?
[18:17:16] amperry: context: hrm. I don't know why it would say that, then.
[18:18:15] amperry: context: if .where returns a relation with a count of 0, I get that error in the form view that uses it.
[18:19:06] amperry: context: "<%= f.collection_select(:supervisor, @supers, :id, :name, include_blank: '-- select --') %>"
[18:22:13] amperry: lemme see, one moment
[18:23:35] amperry: context: hmmm... adding '.all' seems to have done the trick, but I don't know why.
[18:25:03] amperry: context: thanks.

But it just started happening. I rebooted, and am running no other rails process. Why would that happen?

[18:36:59] amperry: Hey folks, I've got a page I want to reload on a change to a select tag, passing the selected value back to the same controller. (A query might return several results, and I want the user to be able to select one). How is that done?
[18:38:41] amperry: I don't see how form_with, link_to, or button_to would do it, and I've tried to create a jquery event listener, but I'm hoping there's a more rails-idiomatic way because I suck at js.

[22:11:53] amperry: hey folks, I've got a scope for a model, Unit.non_revs, which, to_sql, becomes "SELECT `units`.* FROM `units` WHERE `units`.`non_revenue_status_id` IS NOT NULL AND `units`.`null_unit` IS NULL".
[22:13:03] amperry: In the console, I've looked for one unit, u, which I *know* has a non-null 'non_revenue_status_id', and a null 'null_unit'; but Unit.non_revs gives me empty brackets.
[22:14:28] amperry: I don't even know how to troubleshoot this from here.
[22:17:11] amperry: lupine: find_by_id works; when you say by the two args directly, you mean something like Unit.where.not(non_revenue_status_id: nil) ?
[22:17:32] amperry: because u.non_revenue_status_id = 6, which is a valid value, and u.null_unit is nil
[22:20:27] amperry: yeah; it might be that I've changed something in the console and haven't saved it, derp.
[22:20:48] amperry: yup, just me being fuzzy-headed
[22:21:03] amperry: lupine: but thanks anyhow
[22:30:19] amperry: Quit: Thanks, bye for now

[19:09:30] amperry: Hi folks, I'm having a problem with the cocoon gem and a has_many association. When I add multiple associated records to an object, only the last one gets passed to params. (Also, the autonumeric gem doesn't seem to work for fields in the associated record's partial). Gist here: https://gist.github.com/amp108/6d16b42fe89b1ee1adda180544f0ac3a
[19:17:10] amperry: Okay, after some cosmetic editing, problem #2 in my little gist there is fixed, so now I'm just wondering why autonumeric isn't working.
[19:22:26] amperry: Ne'ermind, RTFM'ed on the autonumeric as well.

[16:47:50] amperry: I have weird behavior with a form submission where the request hits the controller and the console claims to render the page for the next action, but the browser window doesn't appear to change (i.e., it's still on the page with the form). Anyone have a guess as to why that might happen?

[16:05:08] amperry: hey folks, I've got a weird 'byebug' problem. I've put it as the very first line in a controller method, but when I invoke that action, I'm dumped into /gems/devise-4.6.1/lib/devise/controllers/helpers.rb, in 'def current_#{mapping}' instead of the first line of my method.
[16:05:12] amperry: why would that be?
[16:05:59] amperry: the *second* line of that method is Pundit.policy_scope call.
[16:07:29] amperry: although stopping and starting the server seems to have fixed it, ne'ermind. I just hate to do the IT Crowd fix without knowing why

[07:24:20] amperry: what could be wrong with me/it?

[12:51:57] amperry: ss942: seems like I was missing a route. But where would I put the Rails.logger.error, assuming (as it was in this case) that no error was logged? (I.e., what 'some string' would I look for?)
[13:03:20] amperry: Giorgio: that's what I would have expected. But it simply silently declined to render anything in the '<%= yield %>' section.

[13:56:57] amperry: is there a way to force ActionView::Template::Error to be more verbose?

[13:59:15] amperry: come to think of it, that is in the gist

[14:02:22] amperry: hi folks, anyone know of either a rake task I can schedule with the 'whenever' gem, or the right way to set up the environment in a crontab to (a) see if a rails server is running, and (b) if not, restart it?
[14:02:54] amperry: https://stackoverflow.com/questions/51831343/cron-job-to-keep-rails-server-running, for context
[14:03:17] amperry: dminuoso: how do I not do that?
[14:04:26] amperry: should be a one-line entry in a crontab, but there seems to be some context and environmental variables that don't get set up when I'm not logged in, and I don't know what all of them are.
[14:14:13] amperry: dminuoso: I don't even know how I'd write the script if "ps auwwx | grep -v grep | grep puma || rails s" works from the command line, but "ps auwwx | grep -v grep | grep puma || /every/path/ive/tried/rails s" fails in a crontab
[14:15:05] amperry: ACTION didn't want to be sysadmin for this, but stumbled into it
[14:16:12] amperry: dminuoso: Scrabe?
[14:20:38] amperry: dminuoso: I'll try that, but that still doesn't get to the problem I'm facing, which is, once I see the server isn't running, how do I get it to start?
[14:22:33] amperry: I'd been just running "rails s" from the command line. (I'm utterly unprepared to be the sysadmin, but the task fell on me against my wishes.)
[14:26:38] amperry: dminuoso: okay. Starting from the ground up, I'm looking at https://docs.docker.com/compose/rails/; do you recommend another resource?

[20:27:37] amperry: Hi folks, I'm getting an error that I have very little to go on, so as a workaround until I can fix that, I want to use either a cron job or scheduled rake task to check if the server is up, and if not, to restart it. I'm having bad luck with the cron approach, however, and I have no idea what a rake task would look like to do this.

[15:21:09] amperry: hi folks, I'm using the nested_form gem and I'm trying to direct to an action, placements#_lease. I've go a line in the template that looks like this:
[15:21:30] amperry: <%= nested_form_for @placement, controller: :placements, action: "_lease" do |f| >
[15:21:45] amperry: ... but the rendered html looks like this:

[15:23:54] amperry: Any idea what I'm doing wrong? How do I make the form go to the action I want it to?
[15:30:28] amperry: Inside: let me try that.
[15:36:45] amperry: Inside: looks like that did it, thanks. (Now off to fix the subsequent errors, sigh...)
[15:42:30] amperry: if I weren't freelancing, I would. But as I'm behind schedule, "security" is the last thing I'm feeling :(
[15:43:40] amperry: I started this thing with (a) a much higher opinion of my Rails skills than I really had, and (b) a much lower appreciation for how messed up the client's original app was.
[18:40:38] amperry: dminuoso: agreed, but what it really lacks is an agreed-upon architecture for doing non-CRUD activities.

[21:42:56] amperry: Hi folks, in addition to STI, how can you model OO-style inheritance between tables with Rails? (I might be fine with STI alone, but I'm looking for options.)
[21:50:13] amperry: GOOD MORNING, RADAR
[22:45:41] amperry: is there a method or command in the rails console to list an object/model's associations?
[22:50:51] amperry: Radar: groovy, thx
[22:58:08] amperry: does it make sense for one model to 'has_many' another model, and the other model to 'has_many' that model, without either of them 'has_and_belongs_to_many'? I'm tempted to try something, but the idea sounds dumb to me.
[23:04:17] amperry: dionysus69: yeah. right now I have a have a model, Placement, which has_many Residents, which (most of the time) act like they belong_to that one Placement. But a Resident can move, and get a new Placement. Placement is a container for everything rental related, including Lease, Apt, Residents, and Ledger.
[23:05:26] amperry: they can also sign a Lease before moving, or renew a Lease (which is not really 'renewing' it, but it's really signing a new one), so they can still be in their current Placement while awaiting the move to the new one.
[23:07:56] amperry: Placement is a container; I would have gone with Lease, but a Resident can be associated with an Apt by placing a deposit on it before they actually sign. This is based on an old app that didn't even have a Lease table, but instead (a) listed everybody on the Lease as a single resident, and (b) created a new Resident every time they moved or re-signed.
[23:08:05] amperry: to give you a taste of the insanity I'm working with.
[23:09:33] amperry: so I needed a way to group people together and conditionally associate them with an Apt, even if they don't sign a Lease, because a non-refundable deposit fee is associated with the Apt and I need to account for that.
[23:11:56] amperry: 19/20 times or more, I'll be querying their present location; but there are some reports and some odd processes that need to see their past locations (including two roommates who go their separate ways) and possible future/prospective one.

[00:23:31] amperry: hi folks, got a question. It looks like, with cocoon, you can't transitively add an association through belongs_to -> has_many. In more concrete terms, my model, Lease belongs_to the model Placement, which has_many MonthlyCharges. I'm trying to use cocoon's link_to_add_association to add one or more MonthlyCharges to the Lease. gist here: https://gist.github.com/amp108/b18acf50ac9395af19324aac55c49257
[00:24:17] amperry: seems like you maybe can't do that, but I'm wondering what my options might be at this point.

[19:37:04] amperry: hi folks, I fear the answer is "no, you've got to roll your own", but can someone confirm that you cannot do transitive (i.e., `:has_many :through`) associations when using cocoon's `link_to_add_association` helper? Gist here: https://gist.github.com/amp108/b18acf50ac9395af19324aac55c49257
[19:43:00] amperry: afk, going to look up nested forms using jquery, et al; I really think there's no way to get cocoon to do it.
[21:29:00] amperry: so if I have a method, placements#sign_lease, how do I create a link_to it? I've tried this:
[21:29:03] amperry: <td><%= link_to 'Move In', :sign_lease , method: :post, id: r.id %></td>
[21:29:43] amperry: but the link that creates doesn't include the id, and therefore neither does the resulting params hash.
[22:01:08] amperry: anyone here at the moment?
[22:02:42] amperry: curious: I've got a method, placements#sign_lease, and a link that goes to http://localhost:3000/sign_lease/71, but I seem to be sidestepping placements#sign_lease.
[22:03:07] amperry: also, a route: POST /sign_lease/:id(.:format) placements#sign_lease
[22:03:41] amperry: but I have byebug in the definition of sign_lease, and I'm not hitting it; instead, I'm redirecting to the home page
[22:04:39] amperry: are there common reasons why this would be?
[22:06:16] amperry: I'm not 100% on that, but I *think* so.
[22:06:34] amperry: I mean, the view where the link is created looks okay (now).
[22:07:11] amperry: And I would expect rails to halt inside 'def sign_lease' before it complained about missing templates or something.
[22:07:44] amperry: hard to say; relatively small, but there are definite oddities about it due to how weird the legacy data is.
[22:13:28] amperry: samort7: https://gist.github.com/amp108/e5b7ab5792d3f89788afab1b8f3028b3
[22:14:11] amperry: I know there's some silliness in the '@lease = @placement.build_lease' and such
[22:16:27] amperry: I might. This is a pretty nascent method right now, I was just wondering why I couldn't actually get to it.
[22:17:34] amperry: and now, with some fiddling, I think I've got it, but still have no real indication of what was wrong in the first place.
[22:18:21] amperry: samort7: thanks for being a sounding board, anyhow
[22:19:39] amperry: okay, here's weirdness:
[22:20:33] amperry: the link_to call specifies 'method: :post', but if I remove "get '/sign_lease/:id'" from routes.rb, it doesn't go to the right place.
[22:22:10] amperry: so if params[:method] = "post", has it really been posted?
[22:35:16] amperry: samort7: googling and seeing something about jquery and turbolinks, so that could be something. Won't be the first time Rails' magic was a little too little David Copperfield and a little too much David Blaine.
[22:37:38] amperry: samort7: thx

[19:55:07] amperry: hey folks, brain freezing here for a second: is there an easier way of writing this: r.lines&.select {|line| line.date >= start_date }.select {|line| line.date <= end_date }
[20:20:02] amperry: dminuoso: thanks.
[20:20:08] amperry: brain no worky today

[22:10:49] amperry: Hey folks, git cloned a repository into a new host and am having trouble getting 'bundle install' to work. I get the error: "An error occurred while installing ffi (1.9.21), and Bundler cannot continue. Make sure that `gem install ffi -v '1.9.21'` succeeds before bundling." and I can't get `gem install ffi -v '1.9.21'` to work, either.
[22:11:25] amperry: it tells me to check a temp file which does not exist for more detail.
[22:20:36] amperry: nope, ubuntu
[22:20:52] amperry: ruby is: 2.3.1p112
[22:21:15] amperry: ubuntu is 16.04.1
[22:28:27] amperry: although it seems like this answer does the trick: https://stackoverflow.com/a/48790761
[22:36:45] amperry: tycoon177: it seems unfortunate, but ultimately inevitable, that one needs to issue (multiple) administrative commands to enable what is (at least in part) a package manager to succeed.
[22:36:50] amperry: but yes, that did it.
[22:40:38] amperry: I get it, it just becomes frustrating, especially when the error messages are not informative :(

[19:44:10] amperry: on a different tack, how do you manually ensure that a submit button will send certain params?
[19:54:07] amperry: mattwc: that could be the problem. What I have is a form that basically presents what's going to be created, then asks for an "okay".
[19:55:01] amperry: So it looks like I just have to re-create the same variables in 'def create' action that I did in 'def new', which seems... whatever.
[19:56:19] amperry: so perhaps using a form was the wrong choice
