Unable to get current user inside django rest serializer - django

Question

I'm unable to get current user inside serializer. I have passed context but still i get error like
"user": [
"This field is required."
]
#Serializer.py
class AddressSerializer(ModelSerializer):
class Meta:
model = Address
fields = "__all__"
def create(self, validated_data):
request = self.context["request"]
validated_data["user"] = request.user
return super().create(validated_data)
#Views.py
class AddAddress(APIView):
permission_classes = [IsAuthenticated]
def post(self, request):
print(request.user)
serializer = AddressSerializer(data=request.data, context={"request":request})
if serializer.is_valid():
serializer.save()
return Response(serializer.data, 200)
return Response(serializer.errors)
#Models.py
class Address(models.Model):
user = models.ForeignKey(Account, on_delete=models.CASCADE)
full_name = models.CharField(max_length=35)
email = models.EmailField(max_length=100)
phone = models.BigIntegerField()
address_line_1 = models.TextField(max_length=500)
address_line_2 = models.TextField(max_length=500)
zip_code = models.IntegerField()
city = models.CharField(max_length=20)
state = models.CharField(max_length=15)
country = models.CharField(max_length=15)
class Meta:
verbose_name_plural = "Address"
def __str__(self):
return self.full_name
I exactly don't know the problem behind this

Answer 1

You can do this with the save() method
class AddAddress(APIView):
permission_classes = [IsAuthenticated]
def post(self, request):
print(request.user)
serializer = AddressSerializer(data=request.data, context={"request":request})
if serializer.is_valid():
serializer.save(user=request.user)
return Response(serializer.data, 200)
return Response(serializer.errors)

Answer 2

Try this:
request = self.context.get('request', None)
instead of this request = self.context["request"]

Answer 3

It because user is required in serializer, mean that user data must be sent when post request.
From your code, you want to add the address according to the user who is logged in. So, user no need send by frontend. Try below:
class AddressSerializer(ModelSerializer):
class Meta:
model = Address
fields = "__all__"
extra_kwargs = {
"user": {"read_only": True}
}
def validate(self, attrs):
# make sure that you have passed request in context serializer
attrs["user"] = self.context["request"].user
return attrs

Answer 4

It is a foreign key. You need to assign the id to it, instead of the entire user.
validated_data["user"] = request.user.id
Event hen if the error persists, then the issue seems to be there is no "user" field in your validated_data. There is issue with the data you are sending in the request to the serializer. If it doesnt match the required fields, then validated data will be empty. Print and check your validated data, and also your request data.
