Ruby on Rails - add ID parameter to all routes

问题

I am wondering what is the best way to implement the following functionality in the Rails routing:

Scenario: an website where users sign up for accounts => accountID (Account) becomes the main entity within the website.

Example: https://basecamp.com/:ID/ - takes the authorized users to the Basecamp dashboard. From here all the URLs contain the :accountID as in https://basecamp.com/:ID/projects - list all the projects under the account.

Many thanks in advance!

Use route prefixing:

scope ":account_id" do
  resources :projects
  ...
end

This will always give you params[:account_id] on each resource controller that is defined within the scope.

Update: Here's an entire example including your "dashboard" default route

scope ":account_id" do
  root :to => "dashboard#index"  # http://example.com/12323/
  resources :projects            # http://example.com/12323/projects
  resources :todos               # http://example.com/12323/todos
  ...
end
