I was following following this online video ( here [this video] ) tutorial for a simple blog. Inside these blog posts are comments. In this tutorial the Devise gem was used and a migration was performed to assign add user_id to posts. I did a migration of add_user_id_to_comments similar to was done in the user_id migration for posts. class AddUserIdToComments < ActiveRecord::Migration def change add_column :comments, :user_id, :integer add_index :comments, :user_id end end My models contain the following: Comment model class Comment < ActiveRecord::Base belongs_to :post belongs_to :user end User model class User < ActiveRecord::Base has_many :posts has_many :comments # Include default devise modu

I am following this tutorial [this video] I am trying to authorize user only If user is admin he should be able to see all post and comments otherwise the normal user can see its own post only .I have read github page but was quite confusing [post_controller.rb] class PostsController < ApplicationController before_action :authenticate_user!, except: [:index, :show] def index @posts = Post.all.order('created_at DESC') end def new @post = Post.new end def show @post = Post.find(params[:id]) end def create @post = Post.new(post_params) @post.user = current_user if @post.save redirect_to @post else render 'new' end end def edit @post = Post.find(params[:id]) end def update @post = Post.find(params[:i

Cites Ignacio Palma Balboa · 2016-03 · Stack Overflow · on “How does blog comments works?”

I was watching rails tutorial by mckenzie [this video] and cannot understand how he makes the comments work for each post. _form partial looks like this: <%= form_for([@post, @post.comments.build]) do |f| %> <p> <%= f.label :name %> <%= f.text_field :name %> </p> <p> <%= f.label :description %> <%= f.text_area :description %> </p> <p> <%= f.submit %> </p> <% end %> So why does he has to call for this [@post, @post.comments.build] ?? Then he makes another partial for _comments that looks like this: <div> <h3><%= comment.name %></h3> <p><%= comment.description %></p> </div> So, how is he able to just call for "comment.name" without using the @ sign if there is no loop going on like @comment.each do

I am making a website for K-pop fans to post whatever about K-pop. I am currently following a tutorial to build the website, however I would like for the user to have the option to upload no photos or one or more photos. How can I achieve this?
