Rails Generated Methods

One of the downsides to Rails' automatic method generation is that sometimes it bites you in the butt.

I've been tearing my hair out trying to figure out why ActionView::Helpers::AssetTagHelper.image_path was behaving strangely all of a sudden.  It didn't help that I had a boatload of local changes and there were multiple layers causing problems.  I am using the Rails Engines plugin, which was alias_method_chaining that method, and I thought the problem was in the aliasing.  But the other AssetTagHelper methods (stylesheet_link_tag, javascript_include_tag, and image_tag) were all correctly aliased and working fine.

It turns out that when I created a RESTful route for my new Image ActiveRecord class that it automatically created an image_path method, overriding the normal one.

I'm going to go look for some glue to see if I can get this hair to stick back on my head.
