Jbuilder gives you a simple DSL for declaring JSON structures that beats manipulating giant hash structures. This is particularly helpful when the generation process is fraught with conditionals and loops. Here's a simple example:.

QUESTION
I recently upgraded from Rails 6.1.4.6 to 7.0.2.2. With this upgrade I switched from webpacker to import maps with sprockets. My repo didn't include turbolinks or stimulus and I didn't feel like adding them now either. So I re-added UJS and most of my tests pass except the action cable feature tests. It seems I cannot get action cable to connect.
Any help would be appreciated!

...ANSWER
Answered 2022-Mar-09 at 22:08Figured out the problem was because I had two applications.js
files. One in app/assets/javascripts/
and another in app/javascript
. Sprockets was serving my asset version of application.js due to my manifest pointing there. I adjusted the manifest and deleted the secondary application.js and all is working.
QUESTION
I'm trying to test my pagination feature with rspec/capybara. I created the articles using FactoryBot but encountered two issues. If I create the data:
- in a
before
block, the data is saved to the database and not wiped after the suite runs. - inside a scenario block and use
save_and_open_page
to see if the data shows on the screen, it doesn't show. So, I believe that the data doesn't have enough time to save.

...ANSWER
Answered 2022-Feb-26 at 19:38Your main issue here is out-of-order execution. You're visiting the page before creating the objects needing for your test, therefore the objects aren't visible on the rendered page (they didn't exist when the page was rendered). For most tests you won't want to be calling visit
in a before block, unless you have a series of test that all require the same test data, and visiting the same page. In this case just move the visit
into the scenario. Additionally, don't over-specify the selectors for the elements you're looking for because it will make your tests brittle. You don't show what your html looks like, but assuming this page is only showing one list of articles then checking for just one of your classes may be enough, or scoping your expectation to a page area, and then using a more general CSS selector

QUESTION
I'm very new to Rails and full-stack development in general. I've just finished Michael Hartl's Ruby on Rails Tutorial 6th edition and am walking through it again to build my first project (i.e. an app that's different from the sample app built in the book, but draws on a lot of the same lessons). Catch is that new project is using Rails 7.
It was going well until I ran into issues around Chapter 7; my app will not render a partial with error messages for bad submissions to the new user form. The code in the partial executes (as verified with debugger, and later with a puts statement to output on console), but the HTML doesn't output (i.e. it cannot be found when inspecting the page in Chrome). There is a CSS issue related to newer version of bootstrap, but I even tried downgrading to the bootstrap version from the book (3.4.1) with no luck. (the offending CSS segment is commented out below)
I've banged my head on this for a few hours. Hoping it's just something dumb I'm missing. If it's a broader issue with Bootstrap vs Importmaps or something I'd also appreciate references on good places to learn these. I am extremely grateful for any ideas!
Edit This definitely isn't an issue with passing local variables into the partial; see code snippet and comment added at the end of this post.

Answered 2022-Feb-14 at 02:28Try this in app/views/users/new.html.erb
<%= render 'shared/error_messages', user: @user %>
If it's a shared partial, maybe make the instance variable generic rather than @user
also. That way it can be reused and less confusing later.

I am upgrading to Rails 7.1 and get a weird error in a view using a JS partial:
Missing partial account/_stripe.js.erb, application/_stripe.js.erb with {:locale=>[:fr], :formats=>[:html], :variants=>[], :handlers=>[:raw, :erb, :html, :builder, :ruby, :jbuilder]}.

QUESTION
I have a Ruby on Rails App that uses jbuilder. I am using jbuilder to help render json responses. Is there a way assign the jbuilder partial to a variable without rendering the result? I have been trying to do something like below, but I am getting this undefined method 'key' for nil:NilClass
error. It seems I am not correctly passing the users model to the user.json.jbuilder
Can anyone offer any help?
ANSWER
Answered 2022-Feb-04 at 00:32You can return the JSON from Jbuilder directly with JbuilderTemplate
combined with .target!
, but the filename is required to start with an underscore. Starting the filename with and underscore denotes it as a partial which means it can't be rendered directly.

I'm trying to set up my first Rails 7 app and have installed Bootstrap 5 properly (you can see by the CSS) and gotten rid of all the error messages, but the javascript functions (i.e. dropdown menus, offcanvas, etc.) aren't working.

I have a new rails 7 application which is using the importmap-rails
gem to manage the javascript frontend libraries.
I am attempting to use the Semantic-UI library, but the dependency for jQuery is not being recognized by the Semantic-UI javascript.
I was unable to pin the Semantic-UI library via importmap, so I added this library to the importmap.rb
manually. Here is a link the cdn for semantic.min.js I am using.
The following error message appears in the console on Chrome Web Tools and the collapsible accordions are not functioning that I have on the page to validate the javascript.

ANSWER
Answered 2022-Jan-10 at 09:40Have you created a Rails app? Looks like you're running rails console
in a directory that has no Rails app created yet.
You should create a new app using rails new [app_name]
, then run rails console
. Or, make sure that you're in the root directory of your existing Rails app.
