Question

Given that I have controllers:

  app/controllers/app1/users_controller.rb
  app/controllers/app2/users_controller.rb

I have in my routes file:

["app1", "app2"].each do |n|

  constraints(:host => "#{n}.com") do
    scope({:as => vn, :module => vn}) do
      resources :users
    end
  end

end

This gives me routes like so:

GET app1_users_path (app1.com/users) { :controller => "app1/users", :action => "index" }
GET app2_users_path (app2.com/users) { :controller => "app2/users", :action => "index" }

I do this for every path, for every “app” in my application.

The problem is, as the no. of both apps and paths grows, so does the no. of paths

n = no_of_paths
a = no_of_apps
(n * a) = "LOADS"

Can anyone think of a way I can set the “module” part of my routes (the controller prefix) as a wildcard so I only have to name each route once?

Something like:

match ":controller/:action(/:id)" => ":host/:controller#:action"

maybe?

I’ve solved this…

Essentially, I was asking the wrong question.

My application serves more than one website so I thought it was prudent to create a controller (and therefore a route) for each “vertical” (site within my app).

The shared behaviour in these controllers went into a module which I included in each controller. ie:

# vertical1/users_controller.rb
class Vertical1::UsersController < ApplicationController
  include UsersControllerTemplate
end

# vertical2/users_controller.rb
class Vertical2::UsersController < ApplicationController
  include UsersControllerTemplate
end

# lib/users_controller_template.rb
module UsersContrllerTemplate

  def index() end

end

In practise, I found that 95% of the time I stuck with the shared behaviour.
Having separate controllers and routes was overkill.

Working fine (and faster) now with one instance for most controllers and one or two name-spaced controllers where I need to customise the behaviour.

I’ve also decided to inherit custom controllers from the default behaviour (rather than include modules):

# vertical1/users_controller.rb
class Vertical1::UsersController < UsersController
  # change some stuff here
end
