I'm getting AssertionError: Not implemented when I tried to change a relation between 2 models to Required to Optional.
Steps to reproduce:
I got in my model user = Required(lambda: User) and then change it to user = Optional(lambda: User, default=None, nullable=True)python migrate.py make, no errorspython migrate.py apply:
Applied:
Traceback (most recent call last):
File "migrate.py", line 8, in <module>
models.db.migrate(**app.config['DB_PARAMS'])
File "/home/www/env/lib/python3.6/site-packages/pony/orm/core.py", line 728, in migrate
return migrate(self, command)
File "/home/www/env/lib/python3.6/site-packages/pony/migrate/command.py", line 61, in migrate

op.apply(db)
File "/home/www/env/lib/python3.6/site-packages/pony/migrate/diagram_ops.py", line 154, in apply
assert False, 'Not implemented'
AssertionError: Not implemented
When I delete the entire DB and all my migrations and run make & apply again all works fine, but now I have to do this migration in my production server.
