i use peewee on many microservices, the time has come for the migration system, i decided on the automatic solution.
I chose your solution, but I have an error at the start
adds one new field to a database table
is_root2 = peewee.BooleanField(default=False)
and the command migrate returns
ValueError: is_root2 is not null but has no default
`"""Peewee migrations -- 002_next.py.
Some examples (model - class or model name)::
> Model = migrator.orm['model_name'] # Return model in current state by name
> migrator.sql(sql) # Run custom SQL
> migrator.python(func, *args, **kwargs) # Run python code
> migrator.create_model(Model) # Create a model (could be used as decorator)
> migrator.remove_model(model, cascade=True) # Remove a model
> migrator.add_fields(model, **fields) # Add fields to a model

Hi,

`
I changed one field in the database table, and the migration shows how I would change more fields, why?
is this solution stable at all? Better to write migrations by hand?
I am using the latest version of peewee and the migrator
peewee==3.14.4 peewee-migrate==1.4.3
