Using Rails 3.1, where do you put your “page specific” JavaScript code?

Question

To my understanding, all of your JavaScript gets merged into 1 file. Rails does this by default when it adds //= require_tree . to the bottom of your appl

Answer 1

I see that you've answered your own question, but here's another option:

Basically, you're making the assumption that

//= require_tree .

is required. It's not. Feel free to remove it. In my current application, the first I'm doing with 3.1.x honestly, I've made three different top level JS files. My application.js file only has

//= require jquery
//= require jquery_ujs
//= require_directory .
//= require_directory ./api
//= require_directory ./admin

This way, I can create subdirectories, with their own top level JS files, that only include what I need.

The keys are:

1. You can remove require_tree - Rails lets you change the assumptions it makes
2. There's nothing special about the name application.js - any file in the assets/javascript subdirectory can include pre-processor directives with //=

Hope that helps and adds some details to ClosureCowboy's answer.
