Rails Controller Namespace

问题

What are advantages and disadvantages of using namespace in ruby on rails. For example: I've many controllers like

CompanyLocations 
CompanyXXXX 
CompanySports 
CompanyActivites
CompanyQQQQQ

I want to put all these controllers in Company folder. What is the rails best practice for this ?

回答1:

You have to create a subfolder inside your controller/ directory, and the same in your views/ directory.

Your controller file should look like

module Company
 class SportsController < ApplicationController

 def index
 end

 end
end

...or

class Company::SportsController < ApplicationController

 def index
 end

end

You can also call your partials this way

render :template => "company/sports/index"

Then in routes.rb

namespace :company do
 resources :sports
end

Just pull your controllers in the folder.
create folder app/controllers/company

and create a controller locations_controller.rb with structure:

module Company
  class LocationsController < ApplicationController
    layout '/path/to/layout'
    append_view_path 'app/views/path/to/views'

    def index
    end

  end
end

in routes.rb use scope :module:

scope module: 'company' do
  get '/locations', to: 'locations#index' # this route in scope
end

this generate routes:

locations_path   GET     /locations(.:format)    company/locations#index

update:

Just tips. For views and layout you can use: ActionController#layout and ActionController#append_view_path.
