示例1: _is_type_bound
# 需要导入模块: from sqlalchemy import types [as 别名]
# 或者: from sqlalchemy.types import SchemaType [as 别名]
def _is_type_bound(constraint):
# this deals with SQLAlchemy #3260, don't copy CHECK constraints
# that will be generated by the type.
if sqla_100:
# new feature added for #3260
return constraint._type_bound
else:
# old way, look at what we know Boolean/Enum to use
return (
constraint._create_rule is not None and
isinstance(
getattr(constraint._create_rule, "target", None),
sqltypes.SchemaType)
