Does anyone have any experience making this work? I installed the plugin and tried the following:

class SomeClass < ActiveRecord::Base    acts_as_Taggable end

class SubClass1 < SomeClass end

class SubClass2 < SomeClass end

SubClass1.tag_with("tag")

and notice that taggable_type = SomeClass

when I do SubClass2.find_tagged_with("tag") a SubClass1 object is returned.

Any help would be greatly appreciated!

Yeah, it has issues. The STI mechanism will force the 'class' column to be 'SomeClass' even if it is actually a subclass of that.

I had to do some nasty hackery to get around that. It involved adding another column that stored the classname of the object. It's messy, and untested, so I would be hesitant about sharing it.

You can get around this by doing this...

SubClass.find_tagged_with("tag").delete_if {|x| !x.kind_of? SubClass1 }
