#21968 closed Bug (fixed)

Django doesn't detect initial migration when an app is a dependency

Reported by: Ubercore Owned by: Andrew Godwin <andrew@…>
Component: Migrations Version: master
Severity: Release blocker Keywords:
Cc: Triage Stage: Accepted
Has patch: no Needs documentation: no
Needs tests: yes Patch needs improvement: no
Easy pickings: no UI/UX: no


I have app A, and app B, neither of which have migrations defined (new project, new apps). app A imports a model as an FK from app B. I make app A's migrations with ./ makemigrations app_a , and app_a/migrations/ is created. In it, app B is marked as a dependency: dependencies = [('app_b', '__first__'),] . If I try to run ./ makemigrations app_b , I get No changes detected in app 'app_b'

If I remove app A's migrations entirely, and re-run app B's makemigrations, I get an initial migration as I would expect.
