Rails - Model name ends with S

Question

I have a model named ActiveDns. When I run

rails g scaffold_controller ActiveDns

I get the message

Plural version of the model detected, using singularized version. Override with --force-plural.

Now, the controller and views are generated pretending that the singular is ActiveDn and the plural is ActiveDns, and I get silly stuff like link_to new_dn_path. The --force-plural argument doesn't appear to fix this:

rails g scaffold_controller ActiveDns --force-plural

still results in controllers using variables named @active_dn and views using new_dn_path, with rails 3.2.3. I am removing files between tries using rails d scaffold_controller ActiveDns.

What's the right way to do this?

Instead of removing the incorrect files manually, you can also just `rails destroy scaffold_controller ActiveDns` — Ben Taitelbaum, Aug 13 '12 at 06:16

What's the right way to do this?

I use inflections to document uncountable entities.

config/initializers/inflections.rb

ActiveSupport::Inflector.inflections do |inflect|
  inflect.uncountable "ActiveDns"
end

Then you get:

$ rails g scaffold_controller ActiveDns
      create  app/controllers/active_dns_controller.rb
      invoke  erb
      create    app/views/active_dns
      create    app/views/active_dns/index.html.erb
      create    app/views/active_dns/edit.html.erb
      create    app/views/active_dns/show.html.erb
      create    app/views/active_dns/new.html.erb
      create    app/views/active_dns/_form.html.erb
      invoke  test_unit
      create    test/functional/active_dns_controller_test.rb
      invoke  helper
      create    app/helpers/active_dns_helper.rb
      invoke    test_unit
      create      test/unit/helpers/active_dns_helper_test.rb

Is this what you wanted?

I tested with rails-3.2 (I guess it should work with rails-3.x)

Open your config/initializers/inflections.rb and add a rule:

ActiveSupport::Inflector.inflections do |inflect|
  inflect.irregular 'dns', 'dnses'
end

And generate the controller

rails g scaffold_controller ActiveDns

And add routes to your config/routes.rb file

resources :active_dnses

Then you should see:

$ rake routes

   active_dnses GET    /active_dnses(.:format)          active_dnses#index
                POST   /active_dnses(.:format)          active_dnses#create
 new_active_dns GET    /active_dnses/new(.:format)      active_dnses#new
edit_active_dns GET    /active_dnses/:id/edit(.:format) active_dnses#edit
     active_dns GET    /active_dnses/:id(.:format)      active_dnses#show
                PUT    /active_dnses/:id(.:format)      active_dnses#update
                DELETE /active_dnses/:id(.:format)      active_dnses#destroy

This solution almost worked for me, with exception of route helper methods. Alhought `rake routes` begaves correctly, the method `new_active_dns_path` does not exist, only `new_active_dnses_path` does, which is strange. Also the method `form_for(@active_dns)` keeps pluralizing in a wrong way — gorn, May 29 '18 at 17:14

I want to share about how I solve my problem.

I have an MVC with a name of Pacman under Data_Warehouse.

Where Pacman is a proper noun. (Cannot be Pacmen with an e, but should be Pacmans with an s)

And Data_Warehouse is like a platform name. (Could be anything, in this case its DataWarehouse::Pacman)

So, I have

Models name - models/data_warehouse/pacman.rb

Views name - views/data_warehouse/pacmans/index.slim

Controller name - controller/data_warehouse/pacmans_controller.rb

The problem is, Rails read this path

data_warehouse_pacmans_path

as

data_warehouse_pacmen_path

because of pluralization.

So

I solved this by adding

ActiveSupport::Inflector.inflections do |inflect|
   inflect.uncountable %w( pacmans )
end

to the inflections.rb file in Rails.

Hope this would helps
