So I checked out new [Rails Routing from the outside in](http://guides.rubyonrails.org/routing_outside_in.html) guide and discovered bunch of useful tricks that I (and maybe you) had no idea you could do. Here they are: + +### Multiple resource definitions on a single line + +```ruby +map.resources :photos, :books, :videos +``` + +### Impose a certain format for resource identifiers + +```ruby +map.resources :photos, :requirements => { :id => /[A-Z][A-Z][0-9]+/ } +``` + +This way, `/photos/3` would not work, but `/photos/DA321` would. + +### Friendlier action names + +Say for your application ‘create’ and ‘change’ make more sense than the default ‘new’ and ‘edit’ you can do + +```ruby +map.resources :photos, :path_names => { :new => 'make', :edit => 'change' } +``` + +You can also do this site-wide also, in your environment.rb + +```ruby +config.action_controller.resources_path_names = { :new => 'make', :edit => 'change' } +``` + +### Trim the fat off resources with :only and :except + + +When you use map.resources, rails generates 7 restful routes for that resource; But what if that resource only needed to be seen and listed, never edited or created? + +```ruby +map.resources :photos, :only => [:index, :show] +``` + +If your application uses a lot of `map.resources` calls but not neccesarily all its generated routes, you can save memory this way. + +### Adding extra routes to your resources + +Instead of fighting the `map.resources` generator by placing a horror like this atop your routes.rb + +```ruby +map.connect '/photos/:id/preview', { :controller => 'photos', :action => 'preview' } +``` + +You can do this to your already mapped resource + +```ruby +map.resources :photos, :member => { :preview => :get } +``` + +This will map all GET’s to `/photos/3` to the preview action of your photos controller + +This can also be used in collections instead of singular members, just change `:member` to `:collection` + +```ruby +map.resources :photos, :collection => { :search => :get } +``` + +This will give you `/photos/search` and hit the search action within the photos controller |
