#27004 closed Bug (fixed)

InconsistentMigrationHistory has false positives with squashed migrations

Reported by: Jarek Glowacki Owned by: nobody
Component: Migrations Version: 1.10
Severity: Release blocker Keywords: InconsistentMigrationHistory squashed migrate

Description 

a -> b -> c

a_sq_b

Migrations a, b, c applied. a_sq_b not.
When graph is built, since a and b are applied, a_sq_b replaces them and becomes c's dependency. However this means that a_sq_b is unapplied while c is. This results in an InconsistentMigrationHistory error when you try to run migrations...

Looks like the results of #25850.

Unless I'm mistaken this seems like quite a critical error..
