I am creating a simple registration/login app in Django Rest Framework using Rest APIs with Django Rest Knox's authentication, in which, upon registration, user will also upload a CSV File (which is an optional field).
I have a Person Model which is an extended (derived or OneToOne) Model of User Model and has FileField for the file to be uploaded.
I have two ModelSerializers, one is based on User Model named MainRegisterSerializer and serializes username, email and password fields, and the other is based on Person Model named RegisterSerializer, which serializes FileField and register field (that is initialized with MainRegisterSerializer class's constructor.
Now, in views.py, I am accessing the RegisterSerializer, to get the data from front that which includes username, email and password fields from User Model, and FileField from Person Model.
But, when I enter data in front-end and upload the file, and click on POST button, I get the following error:
KeyError at /api/v1/register
'username'
on the code line user = User.objects.create_user(validated_data['username'], validated_data['email'], validated_data['password'], validated_data['file']) in serializers.py file.
My views.py is:
from rest_framework.response import Response
from knox.models import AuthToken
from .serializers import RegisterSerializer
class RegisterAPI(generics.GenericAPIView):
serializer_class = RegisterSerializer
def post(self, request, *args, **kwargs):
serializer = self.get_serializer(data=request.data)
serializer.is_valid(raise_exception=True)
user = serializer.save()
token = AuthToken.objects.create(user)
return Response({
"users": UserSerializer(user, context=self.get_serializer_context()).data,
"token": token[1]
})
My serializers.py is:
from .models import Person
from django.contrib.auth.models import User
from rest_framework import serializers
class MainRegisterSerializer(serializers.ModelSerializer):
class Meta:
model = User
fields = ('username', 'email', 'password')
class RegisterSerializer(serializers.ModelSerializer):
register = MainRegisterSerializer()
class Meta:
model = Person
fields = ['register', 'file',]
optional_fields = ['file',]
extra_kwargs = {'password': {'write_only': True}}
def create(self, validated_data):
user = User.objects.create_user(validated_data['username'], validated_data['email'], validated_data['password'], validated_data['file'])
return user
My models.py is:
from django.db import models.
from django.contrib.auth.models import User
class Person(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
file = models.FileField(verbose_name="CSV File")
I have already worked around by trying various solutions told here on stackoverflow, but none of them worked for me, that's why I am posting the question. Any help will surely be appreciated. Thanks.
