Reposting from an issue I opened as I was told this would be more appropriate (https://github.com/rails/rails/issues/7265 ) Although `helper.asset_paths.compute_public_path` is publicly available, it won''t actually return the right value for the asset. It is used by helpers like `image_tag`, but `sprockets` is actually overriding these methods. I''m probably not being super clear. In any case, it makes it very difficult to know what''s going on, and very hard to add your own type of asset, as I''m doing in my gem `swf_fu`. See https://github.com/marcandre/swf_fu/issues/8 My feeling is that it would be best if Rails could cooperate nicely with the gems it uses out of the box so that methods are not overriden by the gems, especially not in an incompatible way. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Core" group.
