Question

I would like to update a vote count by javascript.

My show action:

 <%= render :partial => @car.reviews %> 

The review partial has:

 <p id="review_<%= review.id%>"><%= pluralize(review.votes_count, 'vote') %>

votes/create.js.erb

  $("review_<%= review.id %>").html("<%= pluralize(review.votes_count, 'vote') %>");

The vote gets posted without any problem. But the javascript does not work, ActionView::Template::Error (undefined local variable or method `review’

Answer 1

So the solution is to include the loop in the .js.erb file.

<% @car.reviews.each do |review| %>
 $("#review_<%= review.id %>").html("<%= pluralize(review.votes_count, 'vote') %>");
<% end %>
