获取 getattr()：运行 django 测试时属性名称必须是字符串错误

如何解决获取 getattr()：运行 django 测试时属性名称必须是字符串错误

我是 Django 的新手。我正在构建一个应用，需要对用户对各种用途和功能的访问进行大量控制。

为此，我创建了一个名为“UserType”的模型，其中包含一些用户组作为对象，即扫描仪、守望者、枪手和管理员。

另一个模型，AssignedType，将用户分配给一个或多个 UserType。它有两个字段。 'user' 与 User 模型相关，'user_type' 与 UserType 模型相关。

文件“rights.py”控制用户访问。

一切正常，直到我尝试在 tests.py 中进行测试

以下是我来自tests.py的代码

{'name': 'jack','date': 'Jan-06-2021','age': '24'}

然而，这是抛出以下错误：

from django.test import TestCase,Client
from django.urls import reverse
from DataMech.models import User,UserType,AssignedType 

class TestScanner(TestCase):
    def setUp(self):
        scanner1 = User.objects.create(username='scanner1',password='abc')
        scanner2 = User.objects.create(username='scanner2',password='abc')
        overwatch1 = User.objects.create(username='overwatch1',password='abc')
        overwatch2 = User.objects.create(username='overwatch2',password='abc')
        lancer1 = User.objects.create(username='lancer1',password='abc')
        lancer2 = User.objects.create(username='lancer2',password='abc')
        lancer3 = User.objects.create(username='lancer3',password='abc')
        lancer4 = User.objects.create(username='lancer4',password='abc')
        admin1 = User.objects.create(username='admin1',password='abc')
        scanner,created = UserType.objects.get_or_create(name='scanner')
        overwatch,created = UserType.objects.get_or_create(name='overwatch')
        lancer,created = UserType.objects.get_or_create(name='lancer')
        admin,created = UserType.objects.get_or_create(name='admin')
        AssignedType.objects.create(user=scanner1,user_type=scanner)
        AssignedType.objects.create(user=scanner2,user_type=scanner)
        AssignedType.objects.create(user=overwatch1,user_type=overwatch)
        AssignedType.objects.create(user=overwatch2,user_type=overwatch)
        AssignedType.objects.create(user=lancer1,user_type=lancer)
        AssignedType.objects.create(user=lancer2,user_type=lancer)
        AssignedType.objects.create(user=lancer3,user_type=lancer)
        AssignedType.objects.create(user=lancer4,user_type=lancer)
        AssignedType.objects.create(user=admin1,user_type=admin)
        AssignedType.objects.create(user=admin1,user_type=scanner)

    def test_allow_access_only_if_user_is_authorized_GET(self):

        c = Client()
        c.login(username='scanner1',password='abc')
        response = c.get(reverse('scanner'))
        self.assertEquals(response.status_code,200)
        self.assertTemplateUsed(response,'DataMech/scanner.html')
        c.logout()

        c = Client()
        c.login(username='scanner2','DataMech/scanner.html')
        c.logout()

        c = Client()
        c.login(username='overwatch1',403)
        c.logout()

我的urls.py如下：

ERROR: test_allow_access_only_if_user_is_authorized_GET (DataMech.tests.TestScanner)

我在这里做错了什么？如果需要更多代码，请告诉我。
