Assets break in sub URI deployments

[Benedict Lee]

When deploying to a sub URI, X::Editable::Rails is still looking for assets at /assets instead of /sub-uri/assets, breaking the images and glyphicons.

Edit: This is on Rails 4.0.2, and X::Editable::Rails 1.5.1

So after many hours of trying to figure out the issue, it seems that this is an issue with Capistrano, rake, rails, and sprockets rather than X::Editable::Rails directly. Basically, in order to precompile assets properly, the relative URL root has to be passed to the assets:precompile task. In the end I simply set config.action_controller.relative_url_root = '/sub_uri' inside environments/production.rb and that allowed the paths to compile correctly.
