Ruby on rails -- Render partial file inside .js.erb file

Question

In the HTML header this small javascript works:

application.html.erb

<script type="text/javascript">
               alert("<%= escape_javascript(render('resources/positions')) %>");
</script>

But When I tried to put the same code in a js.erb file, it doesn't work.

I tried to inlcude the file, but not working both ways:

<script src="/assets/resources.js.erb" type="text/javascript"></script>
<%= javascript_include_tag 'resources' %>

app/assets/javascripts/resources.js.erb

alert("<%= escape_javascript(render('resources/positions')) %>");

any ideas ?

Thanks in advance for any help.

I'd check in the generated html that the file you're getting (/assets/resources.js) exists and contains what you expect — Anthony Alberto

So what's the content of /assets/resources.js? Also check the JS console to see if there's any error message — Anthony Alberto

You might have a problem with the asset pipeline then ... what's your configuration for it ? — Anthony Alberto

Sounds like a problem with the asset pipeline.

Try adding

config.serve_static_assets = true

In development.rb

restarted the server and still the same.. I have to use javascript_include_tag ?

<%= javascript_include_tag 'resources' %> and here is my file app/assets/javascripts/resources.js.erb

Yes use javascript_include_tag

Even a simple alert(1); doesn't work.. You're sure it's the good path app/assets/javascripts/resources.js.erb ?

I don't know, it's your app! How does the generated html script tag look?
