gql如何按用户属性选择

query = GqlQuery("SELECT * FROM Atable WHERE owner = :1", users.get_current_user())

您可以尝试GQL方式:

results = db.GqlQuery("SELECT * FROM Atable WHERE owner = :1", users.get_current_user().key())

或者python查询方式:

query = db.Query(Atable)
results = query.filter('owner =', users.get_current_user())

如果您只需要为该用户获取一些数据,那么python查询方法可能更简单。

例如,在类something(db.model)中,可以定义:

@staticmethod
def get_something_by_user(user):

        query = db.Query(Something).filter('users =', user)
        result = query.fetch(limit=1000)

        return result

然后你这样称呼它:

user = users.GetCurrentUser()
results = Something.get_something_by_user(user)
