can't adapt type error with models

[artscoop93.info@…]

Sometimes with Django you want to perform operations which need to pickle model objects, you end up with a can't adapt type error. This is often true when one uses celery, for example.
I have a simple way to resolve this issue for model classes, but I wonder if it's relevant to add this code to Django itself.
This would be a new function in the django.db.models.base.Model class

def __reduce__(instance):
    names = [f.name for f in instance._meta.fields]
    attributes = dict([(name, getattr(instance, name)) for name in names])
    return (instance.__class__, (), attributes)

Worth adding or not ?

Words like "sometimes" aren't very helpful in a bug report.

Django models *should* be serializable already. If you actually look at the code for django.db.models.base.Model, there is already an implementation of __reduce__, and it's a lot more complex than what you propose (for very good reasons).

If you're having problems pickling models, you'll need to provide a specific example that reproduces your problem.
