Just read the django-extra-views documentation. Essentially a formset
can be as simple to use as any of the built-in class-based views, eg:
from extra_views import InlineFormSetView
class EditContactAddresses(InlineF
Any example?

In my experience you should avoid doing such things—it's likely to lead to an
unmanageable code mess. Keep it simple. Consider working without a relational
database.

you should read about metaclasses, basically it enables you to build class
definitions in runtime.

I think you just need to define a generic model. I dont see how what you
are asking is feasible since it would require that (on the fly that
migrations are made). You can write a generic model where the types can be

My idea was to build an user interface for the model definition, so the

But why? You can save the model definition on files, why saving them to

Hi Matthias ,
Thank you, I went for option 1 and it works perfectly!
Funny, the add_to_class function basically does "setattr(cls, name,
value)". So I had the right solution, only you have to do this after
class creation, not inside its __init__ function. Good to know, will
