Transaction Wrapper
FIXME
DBObjectBase
DBObjectBase is a base class for mapped classes.
Example:
from datetime import datetime
from sqlalchemy import Column, DateTime, Integer, String
from sqla_utils import DBObjectBase, Transaction
class DBAppointment(DBObjectBase):
__tablename__ = "appointments"
id = Column(Integer, primary_key=True)
date = Column(DateTime, nullable=False)
description = Column(String(1000), nullable=False, default="")
Appointment items can then be queried like this:
from sqla_utils import begin_transaction
with begin_transaction() as t:
app123 = DBAppointment.fetch_by_id(t, 123)
great_apps = DBAppointment.fetch_all(t, DBAppointment.description.like("%great%"))
It is recommended to add custom query, creation, and update methods:
class DBAppointment(DBObjectBase):
...
@classmethod
def create(cls, t: Transaction, date: datetime, description: str) -> DBAppointment:
o = cls()
o.date = date
o.description = description
t.add(o)
return o
@classmethod
def fetch_all_after(cls, t: Transaction, date: datetime) -> List[DBAppointment]:
return cls.fetch_all(t, cls.start >= dates.start)
def update_description(self, t: Transaction, new_description: str) -> None:
self.description = new_description
t.changed(self)
