are using mezzanine? i'm new django if read mezzanine's documentation advice inherit page (additionally richtext) , blogpost classes. found myself same trouble twice while adding translation capabilities , new custom post types. if object doesn't fit of 2 classes, can inherit models , inject changes desire: http://mezzanine.jupo.org/docs/model-customization.html

i think that's mezzanine way..
