Model inheritance problem
Hi, I posted something similar also to italian Django-it group. I'm using neo4django, but I want to understand things in a more generic way. My case: class MyBaseModel(models.NodeModel): name=StringProperty() class Meta: abstract = True NodeModel it's a graph Node, like a record in a relational DB. I inherit from MyBaseModel: class User(MyBaseModel): email=StringProperty() I wish I could do the following: Tony=User.objects.create(name="Tony",email="t...@anymail.bah") but I got the error: TypeError: 'name' is an invalid keyword argument for this function Should I write the __init__?

Re: Model inheritance problem
Thanks, George, but as I said in the beginning, I'm using neo4django, which surely has StringProperty, otherwise I would have an AttributeError on StringProperty, which I don't have. I should have written: from neo4django.db import models and ... name = models.StringProperty(indexed=True) for completeness. I think I just discovered another neo4django issue, in fact it works perfectly only if such attribute is not defined with indexed = True.

Re: Model inheritance problem
Hmm, no, it does not work even without indexed=True, my mistake. So the "issue" remains.
