Question

        coachings GET    /coachings(.:format)                        {:action=>"index", :controller=>"coachings"}
                  POST   /coachings(.:format)                        {:action=>"create", :controller=>"coachings"}
     new_coaching GET    /coachings/new(.:format)                    {:action=>"new", :controller=>"coachings"}
    edit_coaching GET    /coachings/:id/edit(.:format)               {:action=>"edit", :controller=>"coachings"}
         coaching GET    /coachings/:id(.:format)                    {:action=>"show", :controller=>"coachings"}
                  PUT    /coachings/:id(.:format)                    {:action=>"update", :controller=>"coachings"}
                  DELETE /coachings/:id(.:format)                    {:action=>"destroy", :controller=>"coachings"}

我的路线是正确的，这是我的视图索引

＆lt;％= link_to'摧毁'，指导，：确认'你确定吗？'，：method =＆gt; ：destroy％＆gt;

这是我的控制器

def destroy
    @coaching = Coaching.find(params[:id])
    @coaching.destroy

    respond_to do |format|
      format.html { redirect_to coachings_path }
      format.json { head :ok }
    end
end

为什么我收到此错误的任何想法？我是RoR的新手，这是我自己完成的第一个项目。

Answer 1

使用:delete方法

<%= link_to 'Destroy', coaching, :confirm => 'Are you sure?', :method => :delete %>

Answer 2

在您的link_to中，您使用的destroy方法不是有效的HTTP动词，因此Rails可能默认为POST。您需要使用DELETE代替：

<%= link_to 'Destroy', coaching, confirm: 'Are you sure?', method: :delete %>

在尝试使用Destroy时，没有路由匹配[POST]“/ coachings / 4”
