In Django 5.0, if we create a model with primary ID field with UUIDField,
and another model referencing it, then in Django admin, if we create a
filter of the second model with the first model, an error of
DisallowedModelAdminLookup will be thrown.
in models.py
{{{
from django.db import models
import uuid
# Create your models here.
class Request(models.Model):
id = models.UUIDField(primary_key=True, default=uuid.uuid4,
editable=False, verbose_name='Request ID')
name = models.CharField(max_length=50, blank=True)
class RequestItem(models.Model):
request = models.ForeignKey(Request, on_delete=models.CASCADE,
related_name='items')
description = models.CharField(max_length=255, blank=True)
}}}
in admin.py
{{{
from . import models
@admin.register(models.RequestItem)
class RequestItemAdmin(admin.ModelAdmin):
list_display = (
'request',
)
list_filter = (
'request',
)
@admin.register(models.Request)
class RequestAdmin(admin.ModelAdmin):
list_display = (
'id', 'name'
)
list_filter = (
'id',
)
}}}
Then the filter of request in RequestItemAdmin will throw an error
{{{
DisallowedModelAdminLookup at /admin/uid/requestitem/
Filtering by request__id__exact not allowed
}}}
