Django单元测试：AttributeError：'WSGIRequest'对象没有属性'user' [英] Django unit testing: AttributeError: 'WSGIRequest' object has no attribute 'user'

问题描述

运行测试时，我输出以下错误：

When running the tests i get outputted following error:

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

user = self.request.user AttributeError: 'WSGIRequest' object has no attribute '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。

I have tried switching from MIDDLEWARE to MIDDLEWARE_CLASSES and vice versa. Currently, I'm running Django 2.1.

此外，我尝试过切换中间件的位置，但无济于事。

Also, I have tried switching middleware positions and it didn't help.

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

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'

error output

user = self.request.user AttributeError: 'WSGIRequest' object has no attribute 'user'

推荐答案

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 / zh-CN / 2.1 / topics / testing / advanced /＃the-request-factory ，如果您使用 RequestFactory 并且必须进行设置，则不会执行中间件用户明确。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 user 属性，因此将出现错误。

In the first test test_anonymous, you are not actually setting the user. As per documentation https://docs.djangoproject.com/en/2.1/topics/testing/advanced/#the-request-factory, the middleware are not executed if you use RequestFactory and you have to set the user explicitly. So if you want to test again AnonymousUser, you should set request.user = AnonymousUser(). If you don't do this, the request object will not have the user attribute, and thus the error.
