示例1: connection
# 需要导入模块: from sqlalchemy import testing [as 别名]
# 或者: from sqlalchemy.testing import provide_metadata [as 别名]
def connection(self):
eng = getattr(self, "bind", config.db)
conn = eng.connect()
trans = conn.begin()
try:
yield conn
finally:
if trans.is_active:
trans.rollback()
conn.close()
# propose a replacement for @testing.provide_metadata.
# the problem with this is that TablesTest below has a ".metadata"
# attribute already which is accessed directly as part of the
# @testing.provide_metadata pattern. Might need to call this _metadata
# for it to be useful.
# @config.fixture()
# def metadata(self):
# """Provide bound MetaData for a single test, dropping afterwards."""
#
# from . import engines
# metadata = schema.MetaData(config.db)
# try:
# yield metadata
# finally:
# engines.drop_all_tables(metadata, config.db)
