I tried to override the controller test generator for scaffolding in rails 5.
I found the original file, but can't place it in the template directory.
If I read correctly this post Changing scaffold-controller-generator-templates in Rails, the path should be :
lib/templates/rails/test_unit/controller.rb
or
lib/templates/rails/test_unit/functional_test.rb # from the scaffold sources
Finally I tested lots of combinaisons of directories and files names, but none work.
Does anybody know how to do that ?
How about this path? I found it by chance :)
lib/templates/test_unit/scaffold/functional_test.rb
Maybe following directories are also available for minitest templates
./test_unit
./test_unit/controller
./test_unit/helper
./test_unit/integration
./test_unit/mailer
./test_unit/model
./test_unit/plugin
./test_unit/scaffold

I'm a beginner to both ruby and rails, and using Rails 5.17 to develop a web app for a class.
Creating the empty Rails project was successful, but something is going wrong when creating a new controller. I generated a new controller named cars from the root of the project, which was successful. There was a file in app/controllers named cars_controller.rb which looks like this:
class CarsController < ApplicationController
end
I added a method to this file named hello that does nothing.
I then created a file named cars.html.erb in the app/views/layouts directory. This file is a basic page of html code.
In config/routes.rb, I added the following:
get '/cars', to:: 'cars_controller#hello'
resources: cars
After all of this, I ran rails server, and opened localhost:3000 in a browser. This brings up the normal Ruby on Rails welcome page.
But when I go to localhost:3000/cars, I get the following:
Routing Error
uninitialized constant CarsControllerController
I've tried changing the name of the cars_controller.rb file. I've tried changing the name of the class in the controller file from CarsController to Cars. I've tried many different routes in routes.rb. I finally tried uninstalling Rails 5.17 and installing Rails 5.13.
I'm very confused, and I'd be grateful for any advice I can get. Thanks in advance!
One of the great things about Rails is its preference for convention over configuration. However, for this to really benefit you, you need to stick to doing things “The Rails Way” rather than your own way, wherever possible.
In this case, start by getting rid of your custom get route, and just use resources :cars.
From the command line, run rake routes (you might be able to run rails routes on your rails version too) and see the routes that it has created for you.
Now, rename the method you added to your CarsController from hello to index.
Move your hello.html.erb file from app/views/layout to app/views/cars/index.html.erb.
Finally, start the rails server (rails start) and load the url http://localhost:3000/cars in your browser.

Note that templates in app/views/layout have a special purpose. These are used to apply a general template to your views. Look up the use of layout within a controller for more details
I think you have an error in how you had defined your route - you don't need _controller.
Instead, try this:
get '/cars', to: 'cars#hello'
Also, keep in mind that in your cars directory you need the view: hello.html.erb
I want to customize the controller views generated by haml-rails. According to the Rails guide I am supposed to put my customized templates (e.g. index.html.haml) into lib/templates/[subfolders].
In this case I tried several subfolders (e.g. lib/templates/haml/scaffold, lib/generators/haml/scaffold/templates) but I could not get my custom templates to be used.
I know that I could write another generator easily, but I am wondering if there is a more DRY way to do so. In theory it should be possible:
In Rails 3.0 and above, generators don't just look in the source root for templates, they also search for templates in other paths.
I am using Rails (4.2.5.2), haml (4.0.7) and haml-rails (0.9.0).
Holy moly. It worked after all. It is correct to put the templates into lib/templates/haml/scaffold. And now comes the catch: spring will cache the templates. Hence, you must either restart spring after changes or prepend DISABLE_SPRING to the generator command:
DISABLE_SPRING=true rails g scaffold ...
I'm using emacs 24.3.1 for rails development and currently I end up with enh-ruby-mode when in my rails model files. I would like to use yasnippets for rails commands eg: typing 'bt' + tab expands to belongs_to.
Should my rails templates be put into my enh-ruby-mode snippets directory?
It looks like the repository for the snippets has enh-ruby-mode as a symlink to ruby-mode. Check your yasnippets snippets directory to see if that symlink exists. If not, either update your yasnippets or add the link yourself.

I have an API that has many controllers and models.
I installed Rspec and every new resource I create, the corresponding test files are created automatically.
Is there a way to generate these files for all others old resources including REST tests?
For instance, I have a file costumers_controller.rb created before I install Rspec, is there a way to generate the default file costumers_controller_spec.rb?
I found the answer:
rails g rspec:scaffold controller_name
This generate also the request and routing file.
In order to generate the model just use:
rails g rspec:model model_name
And all test files will be ready to use.
Thanks.
Generate a controller with simple spec examples for the specified actions:
rails g rspec:controller Posts index show create
I'm trying to get custom scaffolding working from my engine.
I followed some tutorial on customizing Rails 3.2 scaffolding in a normal Rails App and put my customized templates in the engines /lib/templates/erb/scaffold directory but they don't get picked up by the app that includes the engine. Any suggestions?
Update:
I also tried to override the Rails ScaffoldGenerator's source_path and tried some other paths to put my template in, like:
lib/rails/generators/erb/scaffold/templates
zarazan's answer got me most of the way there, but there are a couple of things wrong with it. Here's what worked for me:
class Engine < Rails::Engine
config.generators do |g|
g.templates.unshift File::expand_path('../../templates', __FILE__)
end
end
Note that this goes in the generators section, not app_generators, and that the path is slightly different.
Also, I think the correct path to store your templates is lib/templates/erb/scaffold, optionally replacing erb with whatever language you are using (like haml or slim.) I know this works for slim. The file names are {_form,edit,index,new,show}.html.erb.
In the file that you declare your engine use this command:
class Engine < Rails::Engine
config.app_generators do |g|
g.templates.unshift File::expand_path('../templates', __FILE__)
end
end
It should shift the preference of what template folder Rails uses by default.
Now just put the template files in lib/templates/erb/scaffold/template_name.erb
Where template_name is one of the following: _form.html.erb, edit.html.erb, index.html.erb, new.html.erb, show.html.erb
Once you include the gem you should be able to use the rails generate scaffold command as normal.
Here is an example of an engine that overrides the default scaffolding in rails:
https://github.com/brocktoncg/gemboree
This is where the template directory is located:
https://github.com/brocktoncg/gemboree/tree/master/lib/templates/erb/scaffold
Are you talking about a controller template? Than you are using the wrong directory. Save your template at
lib/templates/rails/scaffold_controller/controller.rb
Have a look at http://xyzpub.com/en/ruby-on-rails/3.2/templates.html for an example.
