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

Question

我已经实现了如下所示的测试方法：

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):

为什么会出现以下错误：

Traceback (most recent call last):

    return func(*args, **keywargs)

    response = UserDetailsAPIView.as_view()(request)

Answer 1

你传递的是 kwargs 而不是 args。

替换为：

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