How to retrieve and create data from model via DJANGO REST API?

Question

I am new to Django and Django Rest Framework so I need some help.

I want to receive time data from my model in Django. If there is no time stored for a particular user, it should create it, save it in my model and return that time data. I am also using Simple-JWT for token authentication which means that no one can access the database without a valid token.

This is my code so far:

models.py:

class Mymodel(models.Model):
    emp= models.ForeignKey(User, on_delete = models.CASCADE)
    time = models.DateTimeField()

views.py:

def get_time(request):
    if (request.method == 'GET'):
        tk = request.GET.get('token') #token stored in LocalStorage
        headers = {'Authorization': 'Bearer ' + tk}
        url = 'http://127.0.0.1:8000/my_api/'
        response = requests.get(url, headers)
        if response:
            user_id = User.objects.get(username=request.GET.get('username')).pk
            user = User.objects.get(id = user_id)
            if not Mymodel.objects.filter(emp=user).exists():
                current_time = timezone.now()
                create_time = Mymodel.objects.create(emp=user, time=current_time)
                data = create_time.time
        return HttpResponse(data)

class MyAPI(generics.ListAPIView):
    permission_classes = [IsAuthenticated]  #need to pass in JWT token in order to access the model.
    serializer = MySerializer
    def get_queryset(self):
        user_id = User.objects.get(username=request.GET.get('username')).pk
        user = User.objects.get(id = user_id)
        user_data = Mymodel.objects.all()
        queryset = user_data.filter(id=user_id)
        return queryset

serializers.py:

class MySerializer(serializers.ModelSerializer):

    class Meta:
        model = Mymodel
        fields = ('time')

I just want to read from my table and check whether if time is present for a user. If not, it should create time within the model. But, where am I going wrong? Did I pass in the Bearer token right and isn't the API structure correct? Thank you in advance!

First of all, it's not best practice to use django method based and class based view together and in your model just and auto_now=True

class Mymodel(models.Model):
    emp= models.ForeignKey(User, on_delete = models.CASCADE)
    time = models.DateTimeField(auto_now=True)

it will be automatically filled when instance created and you don't need to do this:

create_time = Mymodel.objects.create(emp=user, time=current_time)
