After user-registration, user wants to post data into Client model ( OnetoOne relationship with User model ). So, I want to access the requested user object inside the serializer-class to create a new row in Client model associated with the requested user.

models.py

class Client(models.Model):
user= models.OneToOneField(User, on_delete=models.CASCADE, null=False, blank=False)
sex = models.CharField(max_length = 6, blank=False, null=False)
location = models.CharField(max_length = 30, null = False, blank = False)  

views.py

class ClientRegister(GenericAPIView):
def post(self, request):  
    user = request.user
    serializer = ClientSerializer(data= request.data)
    if serializer.is_valid():       
        serializer.save()           
        return Response(status= status.HTTP_201_CREATED)
    else:
        return Response(data= 'Invalid Form', status= status.HTTP_400_BAD_REQUEST)

serializers.py

class ClientSerializer(serializers.ModelSerializer):  
class Meta:
    model = Client
    fields = ['sex', 'location']  

def create(self, validated_data):
    sex = validated_data.get('sex')
    location = validated_data.get('location')         

    user =  #------ Want requested user object here ------#
    
    if user.is_client:    
        client = Client(user=user, sex=sex, location=location)
        client.save()
        return client

I have manually added user oject into the data in serializer = CientSerializer(data=request.data). But, It didn't work. Please, tell me how to pass it from views.py or how to access it in serializers.py.

CodePudding user response：

Try to pass the user with sex and location in views

class ClientRegister(GenericAPIView):
    def post(self, request):  
        data = request.data
        user = request.user
         #add user in key
        data['user']=user
        serializer = ClientSerializer(data=data)
        if serializer.is_valid():       
            serializer.save()           
            return Response(status= status.HTTP_201_CREATED)
        else:
            return Response(data= 'Invalid Form', status= status.HTTP_400_BAD_REQUEST)

serializer:

class ClientSerializer(serializers.ModelSerializer):  
   class Meta:
      model = Client
      fields = '__all__'

CodePudding user response：

Pass user when you do serializer.save in post method of views like

def post(self, request):  
    u = request.user
    serializer = ClientSerializer(data= request.data)
    if serializer.is_valid():       
        serializer.save(user=u)           
        return Response(status= status.HTTP_201_CREATED)
    else:
        return Response(data= 'Invalid Form', status= status.HTTP_400_BAD_REQUEST)

Or you can read about passing context from views to serializers and in this context you can pass your required data like -

serializer = ClientSerializer(context = {'request':request}, data=request.data)

then you can have your request object in your serializers and you can get request.user or directly pass it in the context.
