django-allauth DefaultAccountAdapter clean_password（）获得了意外的关键字参数'user'

Question

I have written my own custom account adapter using django-allauth and django 1.10, so that I can specify a regex patterns for passwords to be validated.

This is a snippet of my code:

class MyAccountAdapter(DefaultAccountAdapter):
    def clean_password(self, password):
        if re.match(settings.ACCOUNT_PASSWORD_REGEX, password):
            return password
        else:
            raise ValidationError("Password must be at least 8 characters long, contain one digit and one captalised alphabet")  

I have specified to use this class in my settings.py :

ACCOUNT_ADAPTER = 'app.adapters.MyAccountAdapter'

When I attempt to sign up (ie submit a filled in form), I get the following error:

TypeError at /accounts/signup/

clean_password() got an unexpected keyword argument 'user'

Traceback:

Exception Value: clean_password() got an unexpected keyword argument 'user'

What's the meaning of this cryptic error, and how do I fix it?

Answer 1

Take a look at DefaultAccountAdapter implementation of clean_password :

def clean_password(self, password, user=None):
        """
        Validates a password. You can hook into this if you want to
        restric the allowed password choices.
        """

You are missing the user keyword parameter.
