INSTALLED_APPS = [

from django.db import models

class Statistic(models.Model):
    name = models.CharField(max_length=100)

from rest_framework import serializers
from myapp.models import Statistic

class StatisticSerializer(serializers.ModelSerializer):
    class Meta:
        model = Statistic
        fields = '__all__'

from rest_framework import viewsets
from myapp.models import Statistic
from myapp.serializers import StatisticSerializer

class StatisticViewSet(viewsets.ModelViewSet):
    queryset = Statistic.objects.all()
    serializer_class = StatisticSerializer

from django.urls import include, path
from rest_framework import routers
from myapp.views import StatisticViewSet

router = routers.DefaultRouter()
router.register(r'statistics', StatisticViewSet)

urlpatterns = [
