Django unit testing: AttributeError: 'WSGIRequest' object has no attribute 'user'

Question

当运行测试输出以下错误时：

用户=self.request.user AttributeError: 'WSGIRequest' 对象没有属性 'user'

我试过从 MIDDLEWARE 切换到 MIDDLEWARE_CLASSES，反之亦然。目前，我是运行 Django 2.1.

此外，我尝试过切换中间件位置，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

用户=self.request.user AttributeError: 'WSGIRequest' 对象没有属性 'user'

Answer 1

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，如果您使用 RequestFactory 并且您必须明确设置用户，则不会执行中间件。所以如果你想再次测试AnonymousUser，你应该设置request.user = AnonymousUser()。如果不这样做，请求对象将没有 user 属性，因此会出现错误。
