ruby-on-rails – Rails：.destroy错误的参数数量(0表示1)

对于这一行：@post = Post.destroy in my

PostsController#destroy

我有一个post.rb的模型

我的帖子控制器在这里

class PostsController < ApplicationController
  def new
    @post = Post.new
  end

  def index
    @posts = Post.all
  end

  def create
    @post = Post.new(post_params)

    if @post.save
      redirect_to @post
    else
      render 'new'
    end
  end

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

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

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

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

    if @post.update(params[:post].permit(:title,:text))
      redirect_to @post
    else
      render 'edit'
    end
  end

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

    redirect_to posts_path
  end

end

在我看来,我有这个代码：

<%= link_to 'Destroy',post_path(post),method: :delete,data: { confirm: 'Are you sure?' } %>

这就是我对请求中的参数所说的内容

{"_method"=>"delete","authenticity_token"=>"Pzsnxv8pt+34KIKpYqfZquDv3UpihkINGSJxomMNsW4=","id"=>"3"}

我做错了什么？
