Describe the bug
After creating the migration with the model containing foreign key to itself, migration is failing due to KeyError
. After quick investigation, the exact line containing the bug is ForeignKeyField(model=migrator.orm["model"], ...)
. During execution of this code, "model"
is not yet added to migrator.orm
dict. Instead, the call should look like: ForeignKeyField(model="self", ...)
. After changing it the proposed way, migration has completed successfully.
To Reproduce
Steps to reproduce the behavior:
- Write a model containing a self-referencing foreign key:
class TestModel(Model):
parent = ForeignKeyField("self")
- Create a migration
- Run the migration
Expected behavior
Migration should pass correctly.
