在Mongoengine 0.7.10中,我仍然可以做以下事情:

class User(db.Document):
    email = db.EmailField(unique=True, required=True)
    _password = db.StringField(max_length=255, required=True)

    @property
    def password(self):
        return self._password

    @password.setter
    def password(self, password):
        self._password = bcrypt.generate_password_hash(password)
user = User(email='1@1.com', password='12345')

但是,上面的代码在0.8.0中断: ValidationError: ValidationError (User:None) (_password.Field is required: ['User'])

似乎MongoEngine在启动期间无法识别我的自定义密码设置器.我必须手动编写这些来修复它:

user = User(email='1@1.com')
user.password='12345'

这可能是由于以下变化(来自Mongonengine 0.8升级说明):

Previously, if you had data the database that wasn’t defined in the Document definition, it would set it as an attribute on the document. This is no longer the case and the data is set …

我的Flask应用程序在过去一个月突然变得非常慢,我不知道哪些更改可以将响应时间从1s 提升到30s.

我一直在使用Flask和MongoEngine,Redis也用于缓存.MongoDB与Flask应用程序放在同一台服务器上.

我试过剖析Flask,这是报告:
