How to append URL param through controller?

In my Rails app I want to forward my users to their personal sign in page which is stored in a cookie :user_subdomain. So when a user goes to www.app.com/sign_in, s/he should be automatically forwarded to www.app.com/sign_in/mycompany.

How can this be achieved?

I would like to keep my sign_in_path helper method because it's sprinkled all over my app.

If I simply redirect the new action using redirect_to sign_in_path(:name => cookies[:user_subdomain]) I end up in a loop.

Thanks for any pointers.

# routes.rb:

get 'sign_in', :to => 'sessions#new'

 # sessions_controller.rb:

class SessionsController < ApplicationController

  def new
    params[:name] ||= cookies[:user_subdomain]
  end

  ...

end

Then the solution is easy. You do not need to redirect, you just need optional parameter for your routes.

bound parameters

# routes.rb:

get 'sign_in(/:company_name)', :to => 'sessions#new'
# This will allow
# /sign_in
# and
# /sign_in/mycompany
# Both will lead to same action and you can keep your helper



# sessions_controller.rb:

class SessionsController < ApplicationController

  def new
    params[:company_name] ||= cookies[:user_subdomain]
    # You logic here
  end

...

end
