django-rest-framework how to make model serializer fields required

Question

I have a model that I\'m filling out step by step, it means I\'m making a form wizard.

Because of that most fields in this model are required but have null=Tru

Answer 1

According to link1 and link2, and due to the intended field is null=True, blank=True (like email field of django.contrib.auth.models.User in my example) this will work:

class UserSerializer(serializers.ModelSerializer):

    class Meta:
        model = User
        fields = ('username', 'email', 'password')
        extra_kwargs = {'email': {'required': True,
                                  'allow_blank': False}}
