Is there a simple way to limit nesting to one or two levels deep?

I've been trying to add a feature here where we can also EDIT our comments. 

In comments controller I have added:

  def edit
      @comment = @commentable.comments.find(params[:id])
    end

    def update
       @comment.update!(comment_params)
       redirect_back(fallback_location: root_url)
       render "edit"
    end

__________________________________

And in our views _comment.html.erb partial i added in the div 'links'

<%= link_to 'Edit', [:edit, comment.commentable, comment] %>

__________________________________________________________

I am confused what to populate the edit.html.erb file with. Do you have any suggestions?

Thanks

  azback5 Since the edit link_to  isn't a remote: true, you would be rendering a new view. You might be able to render the comment form within there. If you want it to be a bit more of an SPA feel, you could use the remote: true and then that would render the edit.js.erb where you can then render the form partial and display a modal.

If you want to make it load a new page to edit the comment, then you would need to render the form.

thanks for your help! 

I'm a rookie with javascript and I'm eager to learn it, so I feel obliged to ask...

How would you go about writing the JS to render the form partial and display a modal? 

(Great tutorial by the way, I've been teaching myself and this helped me a great deal)

Thanks for your video. 
I have followed it but I got an error on creating a reply. I'm able to create a comment and delete a reply. 
I get below error header + previous comment when I create a reply. Although when I refresh item show view i see all replies.

NoMethodError at /comments/12/comments
undefined method `comment_url' for #<Comments::CommentsController:0x00000000025e18>
Did you mean?  comment_comment_url

While I followed your video, I have different setup for items:
#controllers/items/comments_controller.rb
@commentable = Item.friendly.find(params[:item_id])

#routes.rb
resources :items do
 resources :comments, only: %i[new create destroy], module: :items
end

What am I missing? 
Thanks

  AhmedNadar It looks like your instance variable commentable got set to a Comment instance instead of an Item. Do you have the app set up for a comment to receive a comment? And when you set the commentable, you should likely be passing in the Item instead of the Comment.
