python - 使用 django 序列化程序将数据保存在数据库中的更好方法

Question

您好，我正在做一个正在制作序列化程序的项目
我使用 postman 发送帖子请求。这工作正常，但这只是应用程序的一小部分，代码会变得非常大。如果有更好的方法来编写更小的代码，那么我想使用它。
现在我保存信息的方式如下
模型.py

class Services(models.Model):
    business = models.ForeignKey(Business, on_delete=models.CASCADE)
    service = models.CharField(max_length=30, blank=True)

序列化程序.py

class ServiceSerializer(serializers.ModelSerializer):
    class Meta:
        model = Services
        fields = ('id', 'business', 'service')

View .py

class ServiceAPIView(APIView):
    permission_classes = [IsAuthenticated]

    def post(self, request):
        data = request.data

        business = Business.objects.get(user=request.user)
        data['business'] = business.pk
        serializer = BusinessSerializer(data=data)
        if serializer.is_valid():
            serializer.save()
            return Response(serializer.data, status=status.HTTP_200_OK)

        return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)

网址.py

urlpatterns = [
    path('service/', ServiceAPIView.as_view()),
]

这是商业模式

class Business(models.Model):
    user = models.ForeignKey(User, on_delete=models.CASCADE)

    business_name = models.CharField(max_length=50, blank=True)

    invoices_terms = models.TextField(max_length=100, blank=True)
    desc = models.TextField(max_length=1000, blank=True)

    website = models.URLField(max_length=200, blank=True)

    tax_percentage = models.DecimalField(blank=True, max_digits=5, decimal_places=3)
    labour_rate_per_hour = models.DecimalField(blank=True, max_digits=5, decimal_places=2)

    tax_hst_number = models.IntegerField(blank=True)

好吧，代码看起来不错，拥有深度模块也可以。
一些更新可能如下:

class ServiceAPIView(APIView):
    permission_classes = [IsAuthenticated,]
    serializer_class = ServiceSerializer
    def post(self, request):
        data = request.data
        business = Business.objects.get(user=request.user)
        data['business'] = business.pk
        serializer = self.get_serializer(data=data)
        serializer.is_valid(raise_exception=True):
        serializer.save()
        return Response(serializer.data, status=status.HTTP_200_OK)

这样你可以为每个 View 请求方法只写一个响应行，避免使用 if/else 语句
