Django单元测试：AttributeError：'WSGIRequest'对象没有属性'user'

Question

运行测试时，我输出以下错误：

user = self.request.user AttributeError：“ WSGIRequest”对象没有属性“ user”

我尝试从MIDDLEWARE切换到MIDDLEWARE_CLASSES，反之亦然。目前，我正在运行Django 2.1。

此外，我尝试过切换中间件的位置，但没有帮助。

settings.py

MIDDLEWARE = (
    "django.contrib.sessions.middleware.SessionMiddleware",
    "django.middleware.common.CommonMiddleware",
    "django.middleware.csrf.CsrfViewMiddleware",
    "django.contrib.auth.middleware.AuthenticationMiddleware",
    "django.contrib.auth.middleware.SessionAuthenticationMiddleware",
    "django.contrib.messages.middleware.MessageMiddleware",
    "django.middleware.clickjacking.XFrameOptionsMiddleware",
    "django.middleware.security.SecurityMiddleware",
    "whitenoise.middleware.WhiteNoiseMiddleware",  # to serve static files
)

test_views.py

from django.test import (TestCase,
                     RequestFactory
                     )
from mixer.backend.django import mixer

from .. import views
from accounts.models import User


class TestHomeView(TestCase):
    def test_anonymous(self):
        req = RequestFactory().get("/")
        resp = views.HomeView.as_view()(req)
        self.assertEquals(resp.status_code, 200,
                          "Should be callable by anyone")

    def test_auth_user(self):
        req = RequestFactory().get("/")
        req.user = mixer.blend("accounts.User")
        resp = views.HomeView.as_view()(req)
        self.assertTrue("dashboard" in resp.url,
                        "Should redirect authenticated user to /dashboard/")

错误输出

user = self.request.user AttributeError：“ WSGIRequest”对象没有属性“ user”

在第一个测试test_anonymous中，您实际上并没有设置用户。根据文档https://docs.djangoproject.com/en/2.1/topics/testing/advanced/#the-request-factory，如果使用RequestFactory，并且必须显式设置用户，则不会执行中间件。因此，如果要再次测试AnonymousUser，则应设置request.user = AnonymousUser()。如果您不这样做，则请求对象将没有request属性，从而导致错误。
