sqlatracker

Inspired by django-field-history

Example

from sqlalchemy import BigInteger, Column
from sqlalchemy.ext.declarative import as_declarative
from sqlatracker.field_tracker import FieldTracker


@as_declarative()
class Base:
    id = Column(BigInteger, primary_key=True, autoincrement=True)


class Example(Base):
    example_field_1 = Column(BigInteger)
    example_field_2 = Column(BigInteger)


FieldTracker.listen_for(
    Example.example_field_1,
    Example.example_field_2,
)

Integrate with your metadata for alembic

from sqlatracker.field_tracker import FieldTracker
from sqlatracker.utils import merge_metadata

target_metadata = merge_metadata(your_metadata, FieldTracker.metadata)
