- model copy
- 3 (after 3 ratings)
Create a copy of a model instance.
Works in model inheritance case where
instance.pk = None is
not good enough, since the subclass instance refers to the
parent_link's primary key during save.
M2M relationships are currently not handled, i.e. they are not copied.
See also Django #4027.

from django.db.models import AutoField def copy_model_instance(obj): initial = dict([(f.name, getattr(obj, f.name)) for f in obj._meta.fields if not isinstance(f, AutoField) and\ not f in obj._meta.parents.values()]) return obj.__class__(**initial)
