Argument called `instance` can't be passed to object creation with G

[ilonajulczuk]

Argument called instance can't be passed to object creation with G. I have a class with instance field and there is a name collision in

self.set_data_for_a_field(model_class, instance, field, persist_dependencies=persist_dependencies, **configuration)

Whole traceback:

In [12]: G(AdminInstanceRole, instance=instance, admin=admin, role=role)

Thanks.

I naively thought that kind of error would never happen!

I will rename it.

In the mean time you can create a copy for the wrapper with a distinct variable name.

@paulocheque thanks :), I will wait for an updates and change pip dependency when the change is available.

Currently my workaround is just using normal django orm model creation for that, but I have a few models with instance field and would like to use django_dynamic_fixture with them too.
