示例1: update_object
# 需要导入模块: import peewee [as 别名]
# 或者: from peewee import CompositeKey [as 别名]
def update_object(obj, only=None):
"""Update object asynchronously.
:param obj: object to update
:param only: list or tuple of fields to updata, is `None` then all fields
updated
This function does the same as `Model.save()`_ for already saved object,
but it doesn't invoke ``save()`` method on model class. That is
important to know if you overrided save method for your model.
.. _Model.save(): http://peewee.readthedocs.io/en/latest/peewee/
api.html#Model.save
