Rails is posting it's syntax out loud when it should be running behind the scenes?

Question

See update: for answer at bottom

Original question:

I have a <script></script> in my page and when it runs it does:-

<% Route.all.each do |route| %>
  var long = "<%= route.longitude %>";
  var lati = "<%= route.latitude %>";
  var title = "Route <%= route.route_number %> Stop <%= route.stop_number %>";
  var id = "<%= route.id %>";
<% end %>

But in Firebug I'm getting this error in console.

SyntaxError: syntax error
[Break On This Error]   
<% Route.all.each do |route| %>
 ^

Update: Turns out to be a firebug issue, works as intended but firebug will post as an error.

Answer 1

This is either related to your environment ("production" doesn't show detailed error and debug info)

Or related to firebug itself (god bless them, couldn't live without it)
