integrate django password validators with django rest framework validate_password

password_serializer.py

import django.contrib.auth.password_validation as validators
from rest_framework import serializers

class RegisterUserSerializer(serializers.ModelSerializer):

    password = serializers.CharField(style={'input_type': 'password'}, write_only=True)

    class Meta:
        model = User
        fields = ('id', 'username', 'email, 'password')

    def validate_password(self, data):
        # validators.validate_password(password=data, user=User)
        # return data
        
        # here data has all the fields which have validated values
        # so we can create a User instance out of it
        user = User(**data)

        # get the password from the data
        password = data.get('password')

        errors = dict() 
        try:
            # validate the password and catch the exception
            validators.validate_password(password=password, user=user)

        # the exception raised here is different than serializers.ValidationError
        except exceptions.ValidationError as e:
            errors['password'] = list(e.messages)

        if errors:
            raise serializers.ValidationError(errors)

        return super(RegisterUserSerializer, self).validate(data)

    def create(self, validated_data):
        user = User.objects.create_user(**validated_data)
        user.is_active = False
        user.save()
        return user

@Adegitetaiwo I had the same problem.

I changed line 18 to

user = self.instance

And it worked better for me.
