Broken migration: 0018_merge_20251008_1414.py references non-existent 0017_model_status_rocksdb_conversion_and_more

[Mounika-Badadh]

Problem

Running python manage.py makemigrations or migrate fails with:

django.db.migrations.exceptions.NodeNotFoundError: Migration ifc_validation_models.0018_merge_20251008_1414 dependencies reference nonexistent parent node ('ifc_validation_models', '0017_model_status_rocksdb_conversion_and_more')

Cause

The merge migration migrations/0018_merge_20251008_1414.py depends on two 0017 migrations:

1. 0017_add_user_ci_index — ✅ exists
2. 0017_model_status_rocksdb_conversion_and_more — ❌ missing

The second migration was never committed or was accidentally deleted. This was introduced in commit db726dc ("Add migration").

Current migrations directory

0016_alter_validationrequest_channel.py
0017_add_user_ci_index.py
0018_merge_20251008_1414.py ← broken
0018_model_status_magic_clamav_alter_validationtask_type.py
0019_alter_validationrequest_file.py

Steps to reproduce

1. Clone the repository
2. Set up the Django environment
3. Run python manage.py makemigrations or python manage.py migrate

Environment

• Django: 5.1.1+
• Python: 3.11

That's interesting, please use the v0.8.3 version that (which was just released) https://github.com/buildingSMART/ifc-validation-data-model/tree/release/0.8.3/migrations while we sort this out. Otherwise, that migration that is being referenced is available in the draft PR text here: buildingSMART/validate#228

@aothms Got it, thanks. We’ll use the v0.8.3 migrations for now while this is being sorted out, and fall back to the migration in draft PR #228 if needed.
