django - SimpleTestCase 中不允许对“默认”的 Django 数据库查询

Question

我尝试运行以下测试，但它们都失败了。我不明白这个错误，因为我的视图没有包含模型。

看法

class ClassroomGradebookView(TemplateView):
    """for choosing first gradebook"""
    template_name = "gradebook/gradebookstart.html"

网址

urlpatterns = [
    path('', views.index, name='index'),
    ....
    path('gradebookstart/', views.ClassroomGradebookView.as_view(),
         name='gradebookstart'),
    ]

测试

class ClassroomGradebookTests(SimpleTestCase):

    def test_classroomgradebook_url_name(self):
        response = self.client.get(reverse('gradebook:gradebookstart'))
        self.assertEqual(response.status_code, 200)

    def test_classroomgradebook_status_code(self):
        response = self.client.get('/')
        self.assertEqual(response.status_code, 200)

错误

AssertionError: Database queries to 'default' are not allowed in SimpleTestCase subclasses. Either subclass TestCase or TransactionTestCase to ensure proper test isolation or add 'default' to gradebook.tests.ClassroomGradebookTests.databases to silence this failure.

触发错误的行是：

response = self.client.get(reverse('gradebook:gradebookstart'))
response = self.client.get('/')
