drf - 仅对post（）方法使用序列化程序

问题描述 投票：0回答：2

我正在使用Django Rest Framework。我已经定义了一个序列化器 - 没有模型的ReceiptLog，当对收据日志发出post（）请求时，它应该在TestCaseCommandRun和TestCaseCommandRunResults中创建条目。收货日志在数据库中不存在，我将其用作端点来接受组合的有效负载并在基础表中创建条目。我不想要对ReceiptLog序列化程序的get（）请求。

以下是代码段。

问题：

  1. 如何确保我只有post（）工作和get（）返回异常
  2. 使用序列化器是最好的方法吗？或者我应该使用viewsets？
  3. 我有一个可浏览的API，它列出了urls.py中的所有api。因此，当我点击收据日志api时，它不应显示任何数据，因为不允许使用get（）。我如何确保这一点？

URLs.朋友

router = routers.DefaultRouter()

router.register(r'test_case_command_runs', views.TestCaseCommandRunViewSet)
router.register(r'test_case_command_run_results', views.TestCaseCommandRunResultsViewSet)
router.register(r'receipt_log', views.ReceiptLogViewSet, base_name='ReceiptLog')

urlpatterns = [
    url(r'^buildInfo', views.build_info),
    url(r'^isActive', views.is_active),
    url(r'^dqf_api/', include(router.urls)),
]

任何帮助都非常感谢。

DRF中的视图非常模块化，您可以选择仅使用所需的HTTP方法。在您的情况下，最好的选择是使用CreateAPIView。

from rest_framework.generics import CreateAPIView


class ReceiptLogView(CreateAPIView):
    serializer_class = serializers.ReceiptLog

这也将确保在使用GET或其他方法时，即使在可浏览的API中也会返回不允许的405方法

我不太了解你的第二个问题，因为视图（和视图集）和序列化器用于不同的目的并且不可互相干扰。

我也建议你改进你的命名。序列化程序名称应以Serializer结尾，以免将它们与模型混淆。

我更新了我的urls.py以包含以下行

url(r'^dqf_api/ReceiptLog/', views.ReceiptLogView.ReceiptLogViewSet.as_view(), name='ReceiptLog')
