I have some classes that inherit from one another, here are the
mappers:
mapper(Content, content, polymorphic_on=content.c.type,
polymorphic_identity='content')
mapper(TvContent, content_tv_metadata, inherits=Content,
polymorphic_identity='tv show')
mapper(SoftwareContent, content_software_metadata, inherits=Content,
polymorphic_identity='software')
mapper(MusicContent, content_music_metadata, inherits=Content,
polymorphic_identity='music')
mapper(MovieContent, content_movie_metadata, inherits=Content,
polymorphic_identity='movie')
And the error I'm getting?
Traceback (most recent call last):

Any ideas? This is using 0.4.1
