Hi again, According to what i have understood the problem till now. You are trying to implement it the wrong way. This is not python, Everything is already built using classes, you are already overriding a class, then extending an overriden class seems complicated. Modularity and loose coupling can be achieved through a completely different way here. Be it clear, a model creates a table in the database. Why are you trying to create the same table again and again with more or less attributes ? Try implementing manytomany fields, foreign =key etc. This may solve your problem .
