Django post save function not able to save role id in profile model

Question

I am creating user in django, on post save using reciever signal to save the Profile, I have profile model like this:

class Profile(models.Model):
    user = models.OneToOneField(base_settings.AUTH_USER_MODEL,on_delete=models.CASCADE)
    has_sharkpod = models.BooleanField("The users organization has a sharkpod", default=False)
    role = models.ForeignKey(Role, on_delete=models.DO_NOTHING, default=1)

    def __str__(self):
        return "Profile: " + self.user.username

This is my role model:

class Role(models.Model):
role_name = models.CharField(null=True, max_length=100) #unique = true
permissions = JSONField()
user = models.ManyToManyField(
    base_settings.AUTH_USER_MODEL, blank=True)
date = models.DateTimeField(auto_now=True)

Now I want to save role as well that is passed in the request body of user creation, But I am not able to do that.

This is my post save function for profile:

@receiver(post_save, sender=User)
def create_user_profile(sender, instance, created, **kwargs):
    if created: 
        Profile.objects.create(user=instance)

Update

My User ViewSet:

class CreateUserViewSet(viewsets.ModelViewSet):
authentication_classes = [JWTAuthentication]
permission_classes = [IsAdminUser, IsAuthenticated]
serializer_class = UserSerializer

def post(self, request, *args, **kwargs):
    serializer = self.get_serializer(data=request.data)
    serializer.is_valid(raise_exception=True)
    user = serializer.save()
    return Response({
        "user": UserSerializer(user, context=self.get_serializer_context()).data,

    })

And my user serializer:

class UserSerializer(serializers.ModelSerializer):
class Meta:
    model = User
    fields = ('username', 'email', 'first_name',
              'last_name', 'id', 'is_active', 'password', 'profile')
    read_only_fields = ('profile', 'is_active', )
def create(self, validated_data):
    user = User.objects.create_user(**validated_data)
    password = validated_data.pop('password')
    user.set_password(password)
    return user

I am Posting this data from postman:

 {
  "username": "testUser",
  "email": "bol@example.com",
  "first_name": "test",
  "last_name": "user",
  "password": "test21234",
  "role_id":"45"
}

User creation is working fine, Profile is also created. Now I want the role_id: 45 to be saved in the database. that is not happening.

Do you have any other signals in the project that work? If not your signals may not have registered correctly. See this post: https://stackoverflow.com/a/21612050/1268926 — Kedar, Jun 10 '21 at 12:32
Please update question with the part of user creation and request. — intelis, Jun 10 '21 at 12:32
The `post_save` signal is **not** passed the request. Your use case is better suited to adding the related `Profile` in your _view_ itself. — Abdul Aziz Barkat, Jun 10 '21 at 12:42
Dear Kedar, Signal is working perfectly fine, I just want to save the role_id in the profile model but that is not happening, also How I will get the role id from request in create_user_profile() function ??? — Bilal Maher, Jun 10 '21 at 12:58
Dear @AbdulAzizBarkat I am saving profile after the user creation, that is working, additionaly i want to save the role id as well, i dont know how to save role id in profile model. — Bilal Maher, Jun 10 '21 at 13:01
