示例1: get_tm_session
# 需要导入模块: from zope import sqlalchemy [as 别名]
# 或者: from zope.sqlalchemy import orm [as 别名]
def get_tm_session(session_factory, transaction_manager):
"""
Get a ``sqlalchemy.orm.Session`` instance backed by a transaction.
This function will hook the session to the transaction manager which
will take care of committing any changes.
- When using pyramid_tm it will automatically be committed or aborted
depending on whether an exception is raised.
- When using scripts you should wrap the session in a manager yourself.
For example::
import transaction
engine = get_engine(settings)
session_factory = get_session_factory(engine)
with transaction.manager:
dbsession = get_tm_session(session_factory, transaction.manager)
"""
dbsession = session_factory()
zope.sqlalchemy.register(
dbsession, transaction_manager=transaction_manager)
return dbsession 示例2: get_tm_session
