How to extend Rails Mountable Engine Assets in Application?

Question

Imagine we have Rails Engine blog .

The engine's structure is:

blog
    assets
    javascripts
        blog
            master.js
            application.js
    controllers
        ...
    helpers
        ...

application.js is

//= require_tree .

master.js holds some JavaScript code.

Also I have my application using this engine at /blog .

My question is: How can I add some JavaScript code to engine from my application?

Answer 1

Solution is:

1. Ensure bundle files (application.js, application.css) on plugin and application have different names. In my example plugin's bundle will be bundle.js, and application's bundle — application.js

2. bundle.js will look like:

   require_tree .

3. application.js will look like:

   require blog/bundle

   require_tree .

The problem was in name overlapping - application's bundle was overlapping engines one.
