        "timezone": "US/Samoa",
        "activity_periods": [
             {
                "log_in": "2020-06-09T21:53:25.120897Z",
                "log_out": null
            },
            {
                "log_in": "2020-06-09T22:02:35.289891Z",

        "username": "karen",
        "timezone": "US/Samoa",
        "activity_periods": []
    }

how can i add activity data to user...?

models.py

class User(models.Model):
    name = models.CharField(max_length=20)
    username = models.CharField(max_length=20)
    password = models.CharField(max_length=20)
    timezone = models.CharField(max_length=32, choices=TIMEZONES, default='UTC')

    def __str__(self):
        return self.name



class Activity(models.Model):
    user = models.ForeignKey(User, related_name="activity_periods",on_delete=models.CASCADE,null=True, blank=True)
    log_in = models.DateTimeField(null=True, blank=True)
    log_out = models.DateTimeField(null=True, blank=True)

    def __str__(self):
        return self.user.name

serializers.py

 class ActivitySerializer(serializers.ModelSerializer):
        class Meta:
            model = Activity
            fields = ['log_in', 'log_out']


 class UserSerializer(serializers.ModelSerializer):
        # Passing login Logout to User
      activity_periods = ActivitySerializer(many=True, read_only=True)

      class Meta:
          model = User
          fields = ['name', 'username','timezone', 'activity_periods']

views.py

class ActivityListView(generics.ListCreateAPIView):

    queryset = User.objects.all()
    serializer_class = UserSerializer
    name = "activity-list"

urls.py

 path('rest/',views.ActivityListView.as_view())

how can i add activity data to user...?

In your UserSerializer, you have the following line:

activity_periods = ActivitySerializer(many=True, read_only=True)

Since read_only is set to True, when you POST data it will not be written to the database. Try setting it to False instead.
