Author:: Tim Graham
Comment:: Correction: 8f30556329b64005d63b66859a74752a0b261315 is the commit where the regression appeared. I'm updating the description with a copy/paste version of the models/admin that I used.

Ticket #28262
- Property Severity Normal → Release blocker
- Property Triage Stage Unreviewed → Accepted
- Property Summary Using lookup with autocreated fields crashes django admin → ModelAdmin.lookup_allowed() incorrectly raises DisallowedModelAdminLookup lookup with reverse relation to origin model

-              v2
+              v3
 {{{
+class AuditSession(Model):
+    auditor = models.ForeignKey(User)
+from django.db import models
+from django.contrib.auth.models import User
+class Institution(Model):
+class AuditSession(models.Model):
+    auditor = models.ForeignKey(User, on_delete=models.CASCADE)
+class Institution(models.Model):
     name = models.CharField(max_length=100)
+class Auditor(Model):
+    user = models.OneToOneField(User)
+    institution = models.ForeignKey(Institution, null=True, blank=True)
+    def __str__(self):
+        return self.name
+class Auditor(models.Model):
+    user = models.OneToOneField(User, on_delete=models.CASCADE)
+    institution = models.ForeignKey(Institution, on_delete=models.CASCADE, null=True, blank=True)
 }}}
 And the following filter in audit session admin:
 {{{
+class AuditSessionAdmin(ModelAdmin):
+from django.contrib import admin
+from .models import AuditSession, Institution, Auditor
+@admin.register(AuditSession)
+class AuditSessionAdmin(admin.ModelAdmin):
     list_filter = (
         ('auditor__auditor__institution'),
+    )
+admin.site.register((Institution, Auditor))
 }}}
