TypeError: __init__() got an unexpected keyword argument about flask-mongoengine

Don't use md5 for password hashing. Use bcrypt.

Is this the reason it fails? Would you kindly give me an example? thanks

No. Use bcrypt. Flask-bcrypt

After active=True in init try adding (_args, *_kwargs) ?
Also WHY have you overrided init?

The way i did it is::::::pseudopython

class User(Document):
    password_hash = StringField()
    new_password = StringField()

    def save():
        if self.new_password:
            self.password_hash = bcrypt(self.new_password)
            self.new_password = None
        super. Document.save()

@houmie Yes, you are correct in that overriding __init__ is the problem and you didn't call super(). If you take a look at monogoengine.base.document.BaseDocument, it does quite a few things in its __init__, setting field values being one of them.

Regarding the actual problem, the error message says exactly what the problem is. Your __init__ didn't accept password_hash keyword.

Though using md5 or bcrypt is not related to the problem, another suggestion for setting a password hash is to do something similar to what Django does.

class User(...):
   def set_password(self, raw_password, hasher=bcrypt, salt_length=1234):
      self.password_hash = hasher(raw_password, salt_length)

user = User.objects.get(email=email)   # or User(email=email)
user.set_password('password123')
user.save()
