I'm coding a simple blog with posts and I can't seem to be able to get the code right for going back to the index page after "destroying" a post. I'm following this tutorial and I'm stuck around minute 14 Tutorial I'm working with ruby 3.0.3 and Rails 7.0.3, the error I'm getting is the following: Error

Below are the relevant pieces of code:

• Controller

    class PostsController < ApplicationController
    before_action :find_post, only: [:show, :edit, :update, :destroy]
    def index
    end
  
    def new
        @post = Post.new    
    end
  
    def create
        @post = Post.new post_params
  
        if @post.save
            redirect_to @post, notice: "post has been saved"
        else
            render 'new', notice: "Post could NOT be saved"
        end
    end
  
    def show
  
    end
  
    def edit
  
    end
  
    def update
        if @post.update post_params
        redirect_to @post, notice: "Your article has been updated"
    else
        render 'edit'
    end
  
    end
  
    def destroy
        @post.destroy
        respond_to do posts_path
    end
    end
  
    private
  
    def  post_params
        params.require(:post).permit(:title, :content)
    end
  
    def find_post
        @post = Post.find(params[:id])
  
    end
  
    end
  

• Show (view)

    <%= @post.title %><br>
    <%= @post.content %>
  
     <br>
     <br>
  
     <%= link_to "Edit", edit_post_path(@post) %>
     <%= link_to "Delete", post_path(@post), data: { :turbo_method => :delete, 
     :turbo_confirm => 'Are you sure?'} %>
  

• Routes

     Rails.application.routes.draw do
      resources :posts
  
     end
  

• Migration

    class CreatePosts < ActiveRecord::Migration[7.0]
     def change
      create_table :posts do |t|
       t.string :title
       t.text :content
  
       t.timestamps
      end
      end
      end
  

I would deeply appreciate any help.

CodePudding user response：

# DELETE /posts/1
def destroy
  @post.destroy
  redirect_to posts_url, notice: "Post was successfully destroyed."
end

This destroy method works with button_to:

<%= button_to "Destroy post", post_path(@post), method: :delete %>

If you want to use link_to:

<%= link_to "Destroy post", post_path(@post), data: { turbo_method: :delete } %>

redirect status has to be changed to status: :see_other:

# DELETE /posts/1
def destroy
  @post.destroy
  redirect_to posts_url, status: :see_other, notice: "Post was successfully destroyed."
end

Turbo DELETE request work in progress: https://github.com/hotwired/turbo-rails/issues/259

CodePudding user response：

When you didn't find a record, is no way to destroy it. Rewrite post finder to:

def find_post
  @post = Post.find_by(id: params[:id])
end

I replaced respond_to with redirect_to, but it is not a principal:

  def destroy
    @post.destroy
  ensure
    redirect_to posts_path
  end

CodePudding user response：

The above error seems to have been fixed with

       def destroy
       @post.destroy
    ensure
        redirect_to posts_path
    end

Now I'm getting a different error referring to my show page:
