Rails Controller

Posted by On 12月 26, 2013 0 Comment

Create basic controller

rails g controller name method

Only controller name

rails generate controller

name is controller name.
If you want to associate it with model, add s.
Example

rails generate controller items

Even if create controller from command, routing is not set by default.

Remove controller

To delete controller, to delete controller files in rails.
But, rails prepares command for it

rails destroy controller name

Add controller to routes.rb as resouces

Route file is in config/routes.rb

ApplicationName::Application.routes.draw do
    resources :items
end

In this way, there are no action in controller.
items#index We can make basic RESTful.
Also, you need to add view by yourself.

Create Controller with Actions

Example

rails generate controller items new show

new, show is action name
In that case , view is also generated
app/views/items/new.html.erb, app/views/items/show.html.erb



class ItemssController < ApplicationController
  def new
  end

  def show
  end
end
[/ruby]
Access
http://localhost:3000/items/new -> new action and go new.html.erb
