How to update an object in Django rest framework

I have a custom user model, and have its model seriazer to with. Its modelviewset also works in displaying the user list.

class UserSerializer(serializers.ModelSerializer):
    password1 = serializers.CharField(write_only=True, style={'input_type': 'password'})
    password2 = serializers.CharField(write_only=True, style={'input_type': 'password'})
    mobile = serializers.IntegerField()

    class Meta:
        model = User
        fields = ('id', 'first_name', 'last_name', 'email', 'mobile', 'password1', 'password2')

    def validate(self, data):
        if data['password1'] != data['password2']:
            raise serializers.ValidationError({'password1': 'Both password must be equal.'})
        return data

    def create(self, validated_data):
        if self.is_valid(True):
            return User.objects.create_user(
                validated_data.get('email'),
                validated_data.get('first_name'),
                validated_data.get('last_name'),
                validated_data.get('mobile'),
                validated_data.get('password1'),
            )

class UserViewSet(viewsets.ModelViewSet):
    queryset = User.objects.all()
    serializer_class = UserSerializer

However, I am trying to update a User object by posting the model's fields and its value in json key value pair format in PUT http method.

{
    "first_name": "Some"
    "last_person": "name"
    "mobile": "0123456789" 
}

But this gives me a 400 bad request error:

{
    "password1": [
        "This field is required."
    ],
    "password2": [
        "This field is required."
    ],
    "email": [
        "This field is required."
    ]
}

How can I update an object with only the partial model fields?

Serializer is considering this fields as obligatory, probably you are putting in your custom model null = False.

That's what PATCH is for as opposed to PUT. It'll pass the partial flag to the serializer will will bypass missing field's validation.
