Hello Lauree,
I change the way to introduce Ajax on the application, I'm following the "Agile Web development for Rails 4.0".
This is the part of the part of the view related with the issue:
<%= form_for(@comment) do |f| %>
<% if @comment.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(@comment.errors.count, 'error') %> prohibited this comment from being saved:</h2>
<ul>
<% @comment.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul> r
</div>
<% end %>
<p style= 'padding-top:10px;'>
<%= f.text_field :text , class:'form-control', required:'', placeholder: 'What is your plan?',style: 'display:table-cell'%>
<%= f.submit 'Post', class: 'btn', style: 'display:table-cell' %>
<%= button_to 'Post', comments_path(comment_id: f),
remote: true %>
</p>
<% end %>
When 'button_to' is selected in the browser it goes to this action in the comments_controller.rb :
def create
@comment = Comment.new(comment_params)
print 'ID of the user that already saved the comment: ' + String(current_user.id)
@comment.users_id = current_user.id
respond_to do |format|
if @comment.save
format.html { redirect_to user_path(current_user.id) }
format.js {}
format.json { render action: 'show', status: :created, location: @comment }
else
format.html { render action: 'new' }
format.json { render json: @comment.errors, status: :unprocessable_entity }
end
end
end
But the line 'format.js' is not launching the file 'create.js.erb' that is in the same folder of the rest of the views of comments... When I check the log it creates the comment and redirect the page to "user_path" but never loads the js file.
Any idea?. I did try with the original app of the book and it works fine, so the problem is in my code.
Thanks & Best regards.

Hello Alfredo,
The problem here is the script tag as you are using it without any attribute as type/language.
Please refer https://developer.mozilla.org/
en/docs/Web/HTML/Element/ for more details. The script tag if not given type will be treated as JavaScript tag.script Hence in your case browser is considering that this script tag contains JavaScript code and giving such errors.
For using coffeescript in script tags you can refer http://forgivingworm.
