Question

from django.test import TestCase
from data.models import Projects

class ProjectTestCase(TestCase):

    def test_project(self):

        Projects.objects.create(name="lion")
        lion = Projects.objects.get(name="lion")
        self.assertEqual(lion.count(), 1)

我使用上面的示例测试用例以及使用此命令运行时 python manage.py test -v3 tests

它正在抛出波纹管错误。

Answer 1

第一：运行makemigrations。

试试这个：

python manage.py makemigrations

第二：lion是Projects object，而不是查询集如果您想获得Projects的计数，请尝试将断言更改为：

self.assertEqual(Projects.objects.count(), 1)

Django unittest失败，找不到表
