Rails: 3.2.11
Ruby: 1.9.3p374

I created a js.erb assets and used url_for method in it. In order to get url_for working, I included:

<% environment.context_class.instance_eval { include ActionView::Helpers } %>
<% environment.context_class.instance_eval { include ActionDispatch::Routing } %>
<% environment.context_class.instance_eval { include Rails.application.routes.url_helpers } %>

at the top of the js.erb file, everything worked fine in development mode, and url_for method translated well into the url I need. But when I precompile assets, rails shows me

rake aborted!
No route matches {:controller=>"external", :action=>"register_event"}

This is what I had for js.erb:69

$('form[action="<%= url_for(controller: 'external', action: 'register_event') %>"]').on('submit', function(event) {

Routes should be fine, because everything worked fine everywhere else, even in live compile with production mode. The error only occurs in precompiling.


Did you disable loading the app on asset precompile? If so you won't have controllers loaded. This looks more like a stack overflow question than a bug report.


Yes. Agree with @schneems. I'm closing it know, but let us know if it is still occurring.

@schneems Thank you, I changed config.assets.initialize_on_precompile = true and everything worked.
