Rails post 删除路径被分配给 GET 方法而不是 DELETE

问：

在我关联评论和帖子后，post_delete_path开始发送 GET 请求而不是 Delete 请求，显示以下错误： <没有路由匹配 [DELETE] “/delete_post.3”>

routes.erb 文件：

Rails.application.routes.draw do
  #get 'posts/index'
  resources :posts do
    resources :comments, only: [:destroy, :create]
  end

  delete'/delete_post', to: 'posts#destroy'

  resources :likes, only: [:destroy, :create]

  resources :sessions, only: [:create, :destroy]
  get 'sessions/new'
  get 'sing_in', to: 'sessions#new'
  get 'sign_out', to: 'sessions#destroy'

  resources :users, only: [:create, :destroy]
  get 'users/new'
  get '/register', to: 'users#new'

  root 'posts#index'
end

职位总监 ：

class PostsController < ApplicationController

  before_action :ensure_user
  before_action :correct_user, only: [:edit, :update, :destroy]

  def index
    @posts = Post.all.order("created_at DESC")
  end

  def show
    @post = Post.find(params[:id])
  end


  def new
    @post = current_user.posts.new
  end


  def create
    @post = current_user.posts.new(post_params)

    if @post.save
      redirect_to post_url(@post)
    else
      render 'new', notice: "Couldn't create the post!"
    end

  end

  def edit
    @post = set_post
  end

  def update
    @post = current_user.posts.find(params[:id])

    if @post.update(post_params)
      redirect_to post_url(@post)
    else
      redirect_to post_url(@post), notice: "Couldn't update the post!"
    end
  end


  def destroy
    @post = current_user.posts.find([params[:id]])

    if @post.destroy
      redirect_to posts_path, notice: "Post has been deleted!"
    else
      redirect_to post_url(@post), notice: "Couldn't delete the post!"
    end
  end


  private

  def correct_user
    @post = current_user.posts.find_by(id: params[:id])
    redirect_to root_path, notice: "You are not authorized to edit this post!" if @post.nil?
  end

  def set_post
    return Post.find(params[:id])
  end

  def post_params
    params.require(:post).permit(:title, :content)
  end


end

在帖子视图中显示文件中的删除按钮：

<%= button_to 'Delete', delete_post_path(@post), method: :delete %>

删除带有 DELETE 请求的帖子的路由未显示，即使在路由文件中指定后也是如此：在此处输入图像描述

我尝试在帖子资源下的路由中指定删除路径，但它使用 GET 方法而不是 DELETE 显示新路径。

resources :posts do
    resources :comments, only: [:destroy, :create]
    delete'/post_delete', to: 'posts#destroy'
end

resources :posts do
   resources :comments, only: [:destroy, :create]
end
delete'/post_delete', to: 'posts#destroy'

此外，我尝试在button_to和link_to之间切换，尽管它没有帮助。

更新：

我发现导致问题的有两件事，首先是路由问题，我用 get 方法而不是 delete 方法定义了一个post_delete路由，尽管我有可以使用的方法，所以我摆脱了它。其次，在删除带有相关评论或点赞的帖子时，我收到 NotNullViolation 错误，因为评论和点赞的post_id不能为空，所以为了克服这个问题，在帖子控制器的 destroy 函数中，我在删除帖子之前删除了与帖子相关的所有评论和点赞： ``` def 销毁 @post = current_user.posts.find（参数[：id]）resources :posts

@post.likes.destroy_all
@post.comments.destroy_all

if @post.destroy
  redirect_to posts_path, notice: "Post has been successfully deleted!"
else
  redirect_to @post
  flash[:notice] = "Can't delete the post!"
end
