How to require assets only for development environment

Question

I'm using the assets pipeline from Rails 3.1 and I want to include some javascript files only if it's the development environment.

Example:

//= require application/jquery
//= require application/jquery_ujs
// next ones only for development environment
//= require application/badglobals
//= require application/consul

Its there a standar way of doing this? Any suggestions?

Update

Looking at the Sprockets current documentation, seems like there is not a way to do this.

Why not just require these in the view? Is it important that they are loaded in the asset? To load them in the view:

<% if Rails.env.development? %>
  <%= javascript_include_tag "application/badglobals" %>
  <%= javascript_include_tag "application/consul" %>
<% end %>

You're right, since I want it only for development really don't need the assets pipeline here. – PabloRosales Oct 04 '11 at 05:20
My first question, a bad one... anyway thanks for the answer. Subscribed to your blog! – PabloRosales Oct 04 '11 at 05:36
@mooddha: Not a bad one at all! It was clear what you were trying to do, you just weren't doing it in the right way. That's all. – Ryan Bigg Oct 04 '11 at 08:18

If you rename your application.js file (or whichever file you're calling //= require ... in) to application.js.erb, you can take advantage of require_asset. i.e:

//= require application/jquery
//= require application/jquery_ujs
<% if Rails.env.development? %>
  <%= require_asset 'application/badglobals' %>
  <%= require_asset 'application/consul' %>
<% end %>
