Question

How can one define a dynamic initial value on a foreign key field?

With the code:

from django.db import models
from django.conf import settings
from django.contrib.sites.models import Site

class Example(models.Model):
    site = models.ForeignKey(Site, initial=settings.SITE_ID)

I’ve the following error:

site = models.ForeignKey(Site, initial=settings.SITE_ID)
Field.__init__(self, **kwargs)
TypeError: __init__() got an unexpected keyword argument 'initial'

I also tried with:

class Example(models.Model):
    site = models.ForeignKey(Site, initial=Site.objects.get(id=settings.SITE_ID))

Thanks in advance

Model fields don’t take an “initial” parameter, they take “default”.
