I'm having a new issue related with this. I have been searching the reason
of it but I cannot fix it.
I have this button:
*<%= button_to 'Go to Gallery', loading_gallery_path,
remote: true %>*
And this is the controller function:
*def gallery respond_to do |format| format.html { redirect_to
user_path(current_user.id) } format.js format.json { render
action: 'show', status: :created, location: @comment } end end*
This is the code of the 'gallery.js.erb' => *$('#user-comments').html("<%=
escape_javascript render(:partial => 'change.html.erb') %>");*
And this is the template that the browser is not rendering: *<% print
'CHANGING' %><p>Testing<p>*
In the log of the application I can see that this template is being opened
by the browser but never rendered in the screen. Below is the log:
