Rails: wrong number of arguments (0 for 1) for .destroy

ruby-on-rails

Solution

You need to provide the `ID` to the `destroy` method:

Post.destroy(params[:id])

As stated here: http://api.rubyonrails.org/classes/ActiveRecord/Relation.html#method-i-destroy

Problem

My error message is "wrong number of arguments (0 for 1)" for this line: @post = Post.destroy in my ``` PostsController#destroy ``` I have a model which is post.rb My Posts Controller is here ``` 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 ``` In my view I have this code: ``` <%= link_to 'Destroy', post_path(post), method: :delete, data: { confirm: 'Are you sure?' } %> ``` This is what it says I have for the parameters in the request ``` {"_method"=>"delete", "authenticity_token"=>"Pzsnxv8pt+34KIKpYqfZquDv3UpihkINGSJxomMNsW4=", "id"=>"3"} ``` What in the heck am I doing wrong??
