python - 为什么我不能在 Django rest-framework unittest 中传递位置参数

问题描述

我已经实现了一个测试方法，如下所示：

request = self.factory.get(reverse('users:user-details', kwargs={'user_id': 'd6cb0d1850241a04caaae516f27762d0c0cbc716'}))
response = UserDetailsAPIView.as_view()(request)

URL路径如下：

url(
        r'users/(?P<user_id>\w+)/details/?$',
        UserDetailsAPIView.as_view(),
        name='user-details'
)

它的API视图如下：

class UserDetailsAPIView(APIView):
    http_method_names = ['get']

    def get(self, request, user_id, *args, **kwargs):

为什么我收到以下错误：

Traceback (most recent call last):
  File "/home/.local/lib/python3.5/site-packages/mock/mock.py", line 1305, in patched
    return func(*args, **keywargs)
  File "/vagrant/apps/users/tests/test_views.py", line 95, in test_get_user_detail_by_user_id
    response = UserDetailsAPIView.as_view()(request)

    response = handler(request, *args, **kwargs)
TypeError: get() missing 1 required positional argument: 'user_id'

解决方案

您作为 kwargs 而不是 args 传递。

替换这个：

request = self.factory.get(reverse('users:user-details', args=('d6cb0d1850241a04caaae516f27762d0c0cbc716',)))
