Question

So I have a function which creates a dynamic model. I accomplish this in a way very similar to AuditTrail (see django wiki).

Sample of code is here:

Is there any way I can make a dynamically-generated class pickle-able? Ideally something thats not a crazy monkeypatch/hack?

Answer 1

I am aware of the problem where pickle can’t store a generated or dynamic class. I solved this by rigging in my dynamic type into the modules dict like so:

new_class = type(name, (models.Model,), attrs)
mod = sys.modules[new_class.__module__]
mod.__dict__[new_class.__name__] = new_class

It’s FAR from a clean or elegant solution, so if someone can think of a more django-friendly way to make this happen, I am all ears. However, the above code does work.
