Hello,
I struggeling with an error message for more than a day now and I
can't figure out what I'm doing wrong. I'm still kindof a newbie with
python/django so it might be very obvious..
I am trying to create an inline form and I want to hide a field in
this form (specific: I want to hide the pk field, for some reason
django doesn't hide this one when it has a different name than "id").
To achieve this I create a class which inherits admin.StackedInline.
In this class I define formset=modelformset_factory(ClientContact).
When trying to view te form in the admin I get an error, the Traceback
is below.
For testing purposes I made a very simple Client/Client model example,
the code is below.
I really appreciate any tips/suggestions/ideas :)

model.py

from django.db import models
class Client(models.Model):
name = models.CharField(max_length=100)
city = models.CharField(max_length=100)
class ClientContact(models.Model):
contact_id = models.IntegerField("id", primary_key=True) #
my database requires this
title = models.CharField(max_length=250)
client = models.ForeignKey('Client')

this line out there is no problem
class ClientAdmin(admin.ModelAdmin):
inlines = [
ClientContactInline,
]
admin.site.register(Client, ClientAdmin)
