you need to pass the username in the serializer.

Then in serializer, you can do something like this:

serializers.py:

class ProfileSerializer(serializers.ModelSerializer):
    user = UserCreateSerializer() # create the serializer for user
    # mention all the other fields in profile model

    class Meta:
        model = Profile
        fields = ('user',) # change this as per your requirement

   def validate(self, attrs):
        # validate the data if you have any conditions.
        return attrs

    def create(self, validated_data):
        # pop out the username from dict to create profile data and then save the user.
        user = validated_data.pop('username')
        profile_obj = Profile.objects.create(**validated_data)
        profile_obj.user = user
        profile_obj.save()
        return {"success": True} # You can return anything that you want so that you can send this in reponse from api.py.

api.py

def post(self, request):
     request_data = request.data
     request_data.update({user: request.user.username})       
     serializer = ProfileSerializer(data=request_data)       
     if serializer.is_valid():
         return Response(serializer.validated_data)

Hi Soumen,

ModelSerializers do not behave in exactly the same way as ModelForm. However, there are intentional design decisions behind these differences. commit is not (and won't ever be) a keyword argument to save().

I believe that the usage of .save() is pretty much adequately documented here.

Hi Folks,

I'm getting this error when I declared like this:

def post(self, request):
        serializer = ProfileSerializer(data=request.data)
        username = request.user.username
        user_details = User.objects.get(username = username)
        if serializer.is_valid():
            serializer_data = serializer.save(commit=False)
            serializer_data.user = user_details
            serializer_data.save()

 File "/home/sou/halanx/env/lib/python3.6/site-packages/rest_framework/serializers.py", line 188, in save
    "'commit' is not a valid keyword argument to the 'save()' method. "
AssertionError: 'commit' is not a valid keyword argument to the 'save()' method. If you need to access data before committing to the database then inspect 'serializer.validated_data' instead. You can also pass additional keyword arguments to 'save()' if you need to set extra attributes on the saved model instance. For example: 'serializer.save(owner=request.user)'.'

please help me guys for this issue!!!

Thank You

Soumen
