在Rails 3中路由自定义操作

Question

I have a very simple question. Trying to figure out what is the simplest way to route the custom action in rails 3.

Let's say i have controller UsersController and action promote_to_premium

Nor

http://localhost:3000/users/#{user_id}/promote_to_premium  

neither

http://localhost:3000/users/promote_to_premium/#{user_id}

works.

Should I specify in routes.rb every custom action that differs from new/delete/update/create/ect/....?????

Thank You.

Answer 1

Yes you need to specify in your routes.rb.
Example:

resources :users do
  member do
    post :promote_to_premium
  end
end

This way you can access the route like this:

http://localhost:3000/users/#{user_id}/promote_to_premium

Answer 2

你应该在routes.rb中使用它：

match "/users/:id/promote_to_premium" => "users#promote_to_premium"

Answer 3

You should mention the route in routes.rb file for custom methods in the controller.

You can specify the routes using either get"" or a match""=>"" or a "post"
when you write get "controller/something" something should be an action(method) called by the name "something" in your controller. But in your case you cannot use get"controller/:id" as there is no ":id" method in your controller. So, you should match your controller/:id to some 'action' in your controller. Hence you need to write

"match users/:id/promote_to_premium"=>  "users#promote_to_premium"

But if you are writing something into the database then you should use ' post '. From whatever i know, i think you can try

match 'users/:id/promote_to_premium' => 'users#promote_to_premium', :via => :post

Yes you need to specify every route. Actually you define the normal routes too with the resource command.

There is a specific wildcard command to allow access of any action, but it is only for debug purposes, because it allows access to actions you may not want to be accessible:

match ':controller(/:action(/:id(.:format)))'
