Rails 5.0 - How to implement in-place editing without using best_in_place gem
I'm building an Events site using RoR which I've just upgraded to v5.0.1 (not moving to 5.1 just yet). My events show page has a comments section at the foot of the page which, so far, only has a create and delete functionality.
I want to add an Edit/Update function to comments so only the user who created the comment can edit the comment if they see fit. I want them to be able to edit their comment whilst on the same page. I don't want to use best_in_place gem as this appears to be on the verge of being dormant having not been updated for 3 years.
I'm trying to implement these changes using remote: true & Ajax but I've never done this before and there doesn't appear to be a clear guide via the internet/SO. Here's my views & controller code -
_comment.html.erb
<% if user_signed_in? %>
<p><%= link_to "Edit", remote: true %></p>
<p><%= link_to 'Delete', [comment.event, comment],
method: :delete,
class: "button",
data: { confirm: 'Are you sure?' } %></p>
<% end %>
*Comments_controller.rb *
def update
@comment.user = current_user
respond_to do |format|
if @comment.update
format.html { redirect_to @comment, notice: 'Comment was successfully updated.' }
format.js { }
format.json { render :show, status: :created, location: @comment }
else
format.html { render :new }
format.json { render json: @comment.errors, status: :unprocessable_entity }
end
end
end
My understanding is that I need to include a .js.erb file in my views/comments folder to deal with this ( edit.js.erb ?) but what I'm not clear on is exactly what javascript code I need to include in order for this to work. Also, I don't think my controller code above seems right - should this go in the Edit action? Do I also need an Event#show action in my events controller as this is where it sits in the views?
Any assistance would be greatly appreciated.
