删除/销毁在 Rails 中不起作用 [英] Delete/Destroy is not working within Rails

问题描述

我正在尝试使用我在 tags_controller 页面中编写的一段代码使删除按钮工作；

I am trying to get a delete button to work using a piece of code I have written within my tags_controller page;

  def destroy
    @tag = Tag.find(params[:id])
    @tag.destroy

    redirect_to :back, notice: 'Tag was successfully deleted!'
  end

当我从本地主机运行时，它抛出如下所示的异常；

When I run from my local host, it throws an exception as shown below;

Routing Error
No route matches [DELETE] "/admin/tags/37/edit"

Rails.root: /Users/laurenwoodhams/Desktop/PROJECT/RAILS-BLOG/-t

这是我的配置路由；

Rails.application.routes.draw do

get '/login' => 'admin/sessions#new'
get '/logout' => 'admin/sessions#destroy'

namespace :admin do
    resources :posts
    resources :tags, except: [:index]
    resources :sessions, only: [:new, :create, :destroy]
    resources :administrators, only: [:index, :edit, :update]
end
end

能否请您检查并解释为什么会发生这种情况?

Could you please examine and explain why this may be occurring?

谢谢

推荐答案

DELETE 是 HTTP 动词(如 GET 或 POST)，意思是..

DELETE is the HTTP verb (like GET or POST) which means..

要创建删除标签的链接，您需要在视图中执行类似操作.

To make a link to delete your tag you'll need to do something like this in your view.

<%= link_to "Delete Tag", @tag, method: "delete" %>

然后它应该可以正常工作.

Then it should work properly.

附言你可以运行 bin/rake routes 来查看你的路由.

P.S. You can run bin/rake routes to see your routes.
