Can I create a ViewHelper for a javascript-block?

Question

I'm cleaning up my code of my Rails-app. I'm using the Raty-gem for my rating system. To render a #average_rating I'm using a script-block (picked this up in some tutorial) in the specific views. But since I'm using the #average_rating in over 6 different views, I was hoping that I could do this more efficient. I already tried to use a HelperMethod for it, but i guess that it doesn't accept 'javascript'.

Script-block:

<script>
$('#average_rating').raty({
    path: '',
    readOnly: true,
    score: <%= @project.average_rating %>
});
</script>

What is the cleanest way of doing this in Rails?

Answer 1

Yes there is cleaner way of defining a JavaScript block using content_for helper method provided by rails. You can define a code snippet inside a named content_for block and can be used anywhere in your views. e.g

<% content_for :rating_code do %>
  $('#average_rating').raty({
    path: '',
    readOnly: true,
    score: <%= @project.average_rating %>
  });
<% end %>
