Comment:
I agree it's kind of tricky when the user can change the ID (as expeced
behaviour is not clear), but the issue also happens in a very normal case,
simply when one is using UUIDs instead of regular autoincremented IDs :
{{{
#!python
from django.db import models
import uuid
class Event( models.Model ):
id = models.UUIDField(primary_key=True, default=uuid.uuid4)
name = models.CharField(max_length=10, blank=False)
def __str__(self):
return self.name
class Person( models.Model ):
id = models.UUIDField(primary_key=True, default=uuid.uuid4)
parent = models.ForeignKey('Event', null=True, blank=True,
related_name='children')
name = models.CharField(max_length=10, blank=True)
def __str__(self):
return self.name
class Visitor(Person):
pass
}}}
{{{
#!python
from django.contrib import admin
from .models import Event, Visitor
class VisitorInline( admin.TabularInline ):
model = Visitor
show_change_link = True
class EventAdmin( admin.ModelAdmin ):
inlines = [VisitorInline,]
admin.site.register(Event, EventAdmin)
}}}
