bixomix 0.1.1

Collection of SQLAlchemy mixins

Bixomix

bixomix is a collection of SQLAlchemy mixins.

Support

• Python 3.9+
• SQLAlchemy 2.0+

Install

pip install bixomix

Usage

Add mixins after the Base class in each model’s parent classes. The order of the mixins doesn’t matter.

from sqlalchemy.orm import DeclarativeBase

from bixomix import CreatedAtMixin, EnabledMixin


class Base(DeclarativeBase):
    pass


class MyModel(Base, CreatedAtMixin, EnabledMixin):
    # Add your own fields here
    ...

Mixins

• CreatedAtMixin: add a created_at datetime field that’s automatically filled with the record’s creation date
• UpdatedAtMixin: add an updated_at datetime field that’s automatically filled with the record’s last update date. Note that on Postgres this is done in Python; for a database-level update you have to create a trigger.
• CreatedUpdatedAtMixin: combined version of the previous two mixins
• EnabledMixin: add an enabled boolean field (default is true)
• EnabledNoMixin: same as EnabledMixin, but the default value is false
• UpdateFromDictMixin: add an update_from_dict method to update a model in-place given a dictionary of attributes
