Here is the controller :-
class CommentsController < ApplicationController
before_filter :load_article, :except => :destroy
before_filter :authenticate, :only => :destroy
def new
respond_to do |format|
format.js
end
end
def create
@comment = @article.comments.new(comment_params)
if @comment.save
redirect_to @article, notice: 'Thanks for your comment'
else
redirect_to @article, alert: 'Unable to add comment'
end
end
def destroy
@article = current_user.articles.find(params[:article_id])
@comment = @article.comments.find(params[:id])
@comment.destroy
redirect_to @article, notice: 'Comment Deleted'
end
private
def load_article
@article = Article.find(params[:article_id])
end
def comment_params
params.require(:comment).permit(:name, :email, :body)
end
end
---------------------
app/views/articles/show.html.erb
-------------------------
<%= render @article %>
<h3>Comments</h3>
<div id="comments">
<%= render @article.comments %>
</div>
<%= link_to "new comment", new_article_comment_path(@article, :format => :js),
:remote => true, :id => 'new_comment_link' %>
---------------
app/views/comments/new.js.erb
$("<%= escape_javascript render(file: 'comments/new.html.erb')
%>").insertAfter('#comments');
$('#new_comment_link').hide();
I am getting the below error :-

Debugging is twice as hard as writing the code in the first place. Therefore,
if you write the code as cleverly as possible, you are, by definition, not
smart enough to debug it.
