我试图在我的应用程序中实现flask-login,它也使用了flask-mongoengine。这是我的用户原型:
class User(db.Document, UserMixin):
username = db.StringField(max_length=80)
email = db.StringField(max_length=255, unique=True)
password = db.StringField(max_length=255, required=True)
active = db.BooleanField(default=True)
def __init__(self, *args, **kwargs):
super(db.Document, self).__init__(self)
try:
self.username = kwargs['username']
self.email = kwargs['email']
self.password = kwargs['password']
except:
flash('Bad arguments for User')
@staticmethod
def salt_password(password):
return generate_password_hash(password)
@property
def is_authenticated(self):
return True
@property
def is_active(self):
return self.active
@property
def is_anonymous(self):
return False
def get_id(self):
return unicode(self._id)
def __repr__(self):
return '<User %r>' % (self.username)
def check_pwd(self, password):
return check_password_hash(self.password, password)
但是,当我从登录视图中调用login_user(user)
函数时,它会调用get_id
的{{1}}方法,但User
会返回self._id
。我也试过None
同样的结果。然后,我尝试明确地添加self.id
字段:
_id
但是,class User(db.Document, UserMixin):
_id = db.ObjectIdField(default=bson.ObjectId())
给了我self._id
而不是用户ID。
如何检索用户的'User u'username'>
?

我找到了解决此问题的方法。我的用户原型使用pymongo更新如下:
def get_id(self):
user_queried = self._get_collection().find_one({'username':self.username, 'email':self.email, 'password':self.password})
if user_queried is not None:
return unicode(user_queried['_id'])
else:
return 'None'

虽然我不知道是否仍然需要您的问题的答案 - 您找到了一个解决方案,您的问题已经过时了。但如果有其他人到来我用以下代码解决了它:
from mongoengine import Document, StringField, FloatField, BooleanField
class User(Document):
name = StringField(primary_key=True, required=True, max_length=50)
mail = StringField(required=True, max_length=255)
password = StringField(required=True, max_length=80)
first_name = StringField(max_length=255)
second_name = StringField(max_length=255)
authenticated = True # BooleanField(required=True, default=True)
is_active = True # BooleanField(required=True, default=True)
meta = {'db_alias': 'users'}
@property
def is_authenticated(self):
return True
@property
def is_active(self):
return True
@property
def is_anonymous(self):
return False
def get_id(self):
return self.name
并添加了以下user_loader
@login_manager.user_loader
def load_user(user_id):
user = User.objects(name=user_id)[0]
return user
