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.
QUESTION
I am learning Hotwire-rails, following both the gorails.com and the Hotwire.dev examples. I am running Ruby 3.0.2 and Rails 6.1.4.1. The symptom is at the very start. After rails new xxx, I edit Gemfile to add gem 'hotwire-rails', then bundle install. At this point my app/javascript/packs/application.js is now:
...ANSWER
Answered 2021-Nov-11 at 12:27This seems like everything is working correctly rails just likes to output what its doing to the console but it should have added those to your file.

In RSpec I would use the following to obtain a Random
which is seeded from the test order random seed. This would give us a reproducible RNG for things like fuzzing:
ANSWER
Answered 2022-Jan-24 at 16:11You can use the --seed parameter when calling minitest or the SEED environment variable, [source code](https://github.com/seattlerb/minitest/blob/fe3992e85b40792cf7bff2a876887d8d9e392068/lib/minitest.rb#L190
QUESTION
I've been stuck on trying to write a system test for a form that manually works in the browser.
I have a Speaker
model that has_one :individual
. The form field looks like this:
ANSWER
Answered 2022-Jan-08 at 01:56Without actually seeing any of the test code the error is coming from it's impossible to know for sure, and I have no idea where Capybara is fitting into this. I'm guessing that what you have is a Speaker model that seems to depend on there being an individual
associated with it, but that's not actually enforced anywhere so when you create the speaker instance in your test without an associated individual it's not being flagged as invalid. If Speaker is supposed to support there not being an associated individual
then your issue is that your full_name
method is returning nil when a string is required. To fix that you could do

QUESTION
I'm trying to learn the TDD approach, to do so I'm using pure Ruby app which is responsible for formatting UK phone number. In my class I want to test if the whitespaces and are removed from given phone number. Basically I'm trying to test the Ruby .delete(' ')
method.
Tested module
...ANSWER
Answered 2021-Oct-05 at 23:04You must define a test-method (the method name must start with test_
).
Inside the test method you define your assertions. In your case, you compare the expected value with the result of your method.
QUESTION
I'm seeing the following error it only is appearing in cron jobs using the whenever gem. The application is working correctly otherwise. The scheduled job doesn't run. But I can run it manually and it does work.
...ANSWER
Answered 2021-Sep-23 at 15:08The issue was related to environment variables and not being able to find the correct path for the gems. I found a solution and updated the schedule.rb file.
QUESTION
In a Rails app, I'm writing Minitest unit tests for a helper class which generates and returns some HTML (to be used as the body content of an outgoing email message). I'm using assert_select
to verify that a particular element is present in the generated HTML.
When the test is run, the line with the assert_select
throws this error:
ANSWER
Answered 2021-Sep-22 at 20:04This error is happening because the test isn't (in more typical Rails fashion) making an HTTP request to a Rails controller, and therefore, assert_select
doesn't automatically know what HTML to inspect, since there's no HTML response.
As the error message suggests, you can fix this by implementing a method named document_root_element
in your test class, and having it return the root node of the HTML that you want inspected. For example:
QUESTION
I'm having trouble developing unit tests for a method that calls itself (a game loop) in Ruby using minitest. What I've attempted has been stubbing the method I'm trying to call in said game loop with my input. Here's the game loop:
...ANSWER
Answered 2021-Sep-21 at 00:21I'm not very familiar with minitest, but I expect you need to wrap the raise(exception)
in a block, otherwise your test code is raising the exception immediately in your test (not as a result of the stubbed method being called).
Something like:

ANSWER
Answered 2021-Aug-02 at 08:30I think you need a webpacker.yml
file in your apps config
file. I also suggest running bundle install
and bundle update
commands before launching the rails server after you installed a gem. Here's a closed issue similar to your problem; https://github.com/rails/webpacker/issues/940
