从索引向Rails脚手架类添加操作

Question

I've created a new todo object with

rails g scaffold todo title:string commplete:boolean 

And want to add an action to the index to complete a todo with one click.

So I created an action complete on the todos controller and then add the following to the index page .

<td><%= link_to 'Complete', complete_todo_path(todo) %></td>

While this is the same as the edit command it will not work.

I just get undefined method complete_todo_path

Why does edit work, but the new method does not?

Answer 1

Try this.

resources :todos do
  member do
    get :complete
  end
end

You have edit to your routes.rb file as above.

Note: add complete action to before_action :set_todo to access the todo object in complete action view file
