ruby-on-rails-3 - Rails 从另一个控制器中调用 destroy 方法

Question

我有一个，friendships_controller但我想从. 实际上，按照我的设置方式，该方法可以正常工作，但不能。createdestroyusers_controllercreatedestroy

用户/索引

<%= button_to "+ Add Friend", :controller => "friendships", :action => 'create', :method => "post", :id => user.id %>
<%= button_to "- Unfriend", {:controller => "friendships", :action => 'destroy'}, :confirm => "Are you sure you want to unfriend #{user.username}?", :method => :delete, :id => user.id %>

如果我单击 Unfriend 按钮，我会得到跟随 rails 异常：

ActiveRecord::RecordNotFound in FriendshipsController#destroy
Couldn't find User with ID=destroy

这是destroy里面的动作friendships_controller：

  def destroy
    @accepting_user = User.find(params[:id])
    @friendship = Friendship.find_by_accepting_user_id_and_requesting_user_id(@accepting_user.id, current_user.id)
    @friendship.destroy
    flash[:notice] = "You unfriended #{@friendship.accepting_user.username}."
    redirect_to(:back)
  end

有人对此有任何想法吗？谢谢。

rake routes | grep friendship

                 friendships GET    /friendships(.:format)                                            {:controller=>"friendships", :action=>"index"}
                             POST   /friendships(.:format)                                            {:controller=>"friendships", :action=>"create"}
              new_friendship GET    /friendships/new(.:format)                                        {:controller=>"friendships", :action=>"new"}

                             PUT    /friendships/:id(.:format)                                        {:controller=>"friendships", :action=>"update"}
                             DELETE /friendships/:id(.:format)                                        {:controller=>"friendships", :action=>"destroy"}

得到它的工作，只需要移动我经过的地方:id

最终结果如下所示：

<%= button_to "- Unfriend", {:controller => "friendships", :action => 'destroy', :id => user.id}, :confirm => "Are you sure you want to unfriend #{user.username}?", :method => :delete %>
