Class function is not found

Question

I have the problem with creation of Referral from pinax-referrals package. Referral class has class function create(...) When I am trying to create referral inside view like:

from pinax.referrals.models import Referral

def createReferral(user):

    referral = Referral.create(
        user = user,
        redirect_to = "/"
    )

It throws me following error:

type object 'Referral' has no attribute 'create'

The code inside Pinax model looks ok:

@classmethod
def create(cls, redirect_to, user=None, label="", target=None):
    if target:
        obj, _ = cls.objects.get_or_create(
            user=user,
            redirect_to=redirect_to,
            label=label,
            target_content_type=ContentType.objects.get_for_model(target),
            target_object_id=target.pk
        )
    else:
        obj, _ = cls.objects.get_or_create(
            user=user,
            label=label,
            redirect_to=redirect_to,
        )

    return obj

As I understand the problem is not connected to the Pinax package itself and looks really strange. Does anybody have any ideas?

Answer 1

It sounds like you have defined another class Referral inside the same module, that has replaced Pinax's Referral model.

This could happen because you have defined a class,

class Referral(View):
    ...

or maybe you have imported another class Referral. It might not be obvious this has happened if you do a * import.

from mymodule import *

A useful tool to debug is to add print(Referral) to you view. Then you will see whether the Referral class is the one you expect.
