How to prevent Rails controller generator to modify config/routes.rb

Question

Sometimes I run a command like rails g controller foo index to generate skeletons for controller and template.

Because I don't want to have helpers and assets for every controller, I put following codes into config/application.rb:

config.generators do |g|
  g.helper false
  g.assets false
end

There is another thing I don't want to happen. The generator adds a line get "foo/index" to my config/routes.rb. How can I prevent it?

Is someone going to create a pull request for this feature? – Ivan Denysov Jan 09 '14 at 20:13 — Ivan Denysov, Jan 09 '14 at 20:13
@IvanDenisov it's now part of Rails as of Rails 4.2. – sevenseacat Oct 27 '14 at 00:58 — sevenseacat, Oct 27 '14 at 00:58

As of Rails 4.2, it's possible to disable route generation with the following code in your application.rb:

config.generators do |g|
  g.skip_routes  true
end

Looks like routes generation is hardcoded. Have a look at this method https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/controller_generator.rb#L12

I think, the simplest way is to override with monkey-patch . Something like

module Rails
  module Generators
    class ControllerGenerator < NamedBase 
      def add_routes
        #do nothing...
      end
    end
  end
end

you can put it to initializer and try.

Thanks. It seems that there is no easy way to disable this feature of controller generator. It will be enough for me to confirm this fact... – Tsutomu Jan 08 '14 at 10:10
This is no longer a correct answer. `skip_routes true` is the correct solution as of Rails 5 – ekampp Mar 09 '16 at 19:17

untested...

config.generators do |g|
  g.resource_route false
end

Mr. Ronald, unfortunately, your suggestion does not change the behavior of controller generator. Tested on Rails 4.1.0.beta1. Thanks, anyway. – Tsutomu Jan 01 '14 at 10:26
This should be the code: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/assets/assets_generator.rb => DOES include options. https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/resource_route/resource_route_generator.rb => DOES NOT include options :-( – Mr. Ronald Jan 02 '14 at 15:16
It seems that `g.resource_route` controls the behavior of resource generator, but does not change that of controller generator. – Tsutomu Jan 03 '14 at 04:46
Agree with your comment above that it doesn't look like you can stop the controller generator from generating a route (unless you don't pass it any actions - it appears if there are no actions passed no route is generated). You could also write a template to run after you generate a controller that used `gsub_file` to remove the offending routes. But I would agree if you felt that all of these solutions sound like more work than just deleting the routes from routes.rb. – Steve Rowley Jan 05 '14 at 21:08

If you want to avoid assets or helpers for all controllers, then you can write the following lines in application.rb

config.generators.stylesheets = false
config.generators.javascripts = false
config.generators.helper = false

But if want to avoid for any 1 controller then you generate controller like this

rails g controller test --no_assets
rails g controller test --no_helper
rails g controller test --no_javascripts
rails g controller test --no_stylesheets

Since you want this particular application to not generate routes.

You can deploy your gems to local/project folder and override them.

In your rails project folder

bundle install --path /my_rails_path/lib/

Now you can see all of you libraries ported to your project lib/ folder

Go to the below file (path changes depending upon your versions)

lib/ruby/1.9.1/gems/railties-3.2.15/lib/rails/generators/rails/controller/controller_generator.rb

and comment the function add_routes

  def add_routes
    #actions.reverse.each do |action|
    #  route %{get "#{file_name}/#{action}"}
    #end
  end

NOTE: This trick will not affect any other rails application in your system

This is counter intuitive, but here it is what you're looking for:

config.generators do |g|
  g.skip_routes true
end
