Routes for STI models

sti_routes.rb

# If you want url_for(CoolProject) to give you 'cool_projects/1' but still go to ProjectsController then:
resources :cool_projects, :controller => :projects

# If you want url_for(CoolProject) to give you 'projects/1' and also go to ProjectsController then: 
resources :cool_projects, :controller => :projects, :as => :projects

# If you want to reuse stuff inside resources:
projects_inner = lambda do
  member do
    resources :submodels
  end
end
resources :cool_projects, :controller => :projects, :as => :projects, &projects_inner
resources :projects, &projects_inner

# If you want to pass a parameter of type then:
resources :cool_projects, :controller => :projects, :as => :projects, :type => 'CoolProject', &projects_inner
resources :projects, :type => 'Project', &projects_inner
