Comment (by hugotacito):
Hello MarkusH, the problem is that my code is used by different companies
with different databases, so I think it's hard to manage squashed
migrations between all the companies. Although I solved my problem with
this diff:
{{{
diff --git a/django/db/migrations/executor.py
b/django/db/migrations/executor.py
index fb9c7a9..25170c3 100644
--- a/django/db/migrations/executor.py
+++ b/django/db/migrations/executor.py
@@ -135,6 +135,8 @@ class MigrationExecutor(object):
# Only mutate the state if the migration is actually
applied
# to make sure the resulting state doesn't include
changes
# from unrelated migrations.
+ if 'apps' in state.__dict__:
+ delattr(state, 'apps') # Remove the render all
migration.mutate_state(state, preserve=False)
applied_migrations.remove(migration)
}}}
