Django测试框架中的login() [英] login() in Django testing framework

问题描述

我已经开始使用Django的测试框架，并且一切正常，直到我开始测试经过身份验证的页面为止.

I have started using Django's testing framework, and everything was working fine until I started testing authenticated pages.

为简单起见，我们说这是一个测试:

For the sake of simplicity, let's say that this is a test:

class SimpleTest(TestCase):
    def setUp(self):
        user = User.objects.create_user('temporary', '[e-mail]', 'temporary')

    def test_secure_page(self):
        c = Client()
        print c.login(username='temporary', password='temporary')
        response = c.get('/users/secure/', follow=True)
        user = User.objects.get(username='temporary')
        self.assertEqual(response.context['email'], '[e-mail]')

运行此测试后，它失败，并且我看到login()的打印返回值返回 True ，但是 response.content 被重定向到登录页面(如果登录失败，身份验证装饰器将重定向到登录页面.我在做身份验证的装饰器中设置了一个断点:

After I run this test, it fails, and I see that printing return value of login() returns True, but response.content gets redirected to login page (if login fails authentication decorator redirects to login page). I have put a break point in decorator that does authentication:

def authenticate(user):
    if user.is_authenticated():
        return True
    return False

，它实际上返回 False . test_secure_page()中的第4行正确地检索了用户.

and it really returns False. Line 4 in test_secure_page() properly retrieves user.

这是查看功能:

@user_passes_test(authenticate, login_url='/users/login')
def secure(request):
    user = request.user
    return render_to_response('secure.html', {'email': user.email})

当然，如果我尝试通过应用程序登录(测试之外)，一切正常.

Of course, if I try to login through application (outside of test), everything works fine.

推荐答案

问题是您没有将RequestContext传递给模板.

The problem is that you're not passing RequestContext to your template.

此外，您可能应该使用login_required装饰器和TestCase类中内置的客户端.

Also, you probably should use the login_required decorator and the client built in the TestCase class.

我会这样重写它:

#views.py
from django.contrib.auth.decorators import login_required
from django.shortcuts import render
from django.contrib.auth import get_user_model

@login_required(login_url='/users/login')
def secure(request):
    user = request.user
    return render(request, 'secure.html', {'email': user.email})



#tests.py
class SimpleTest(TestCase):
    def setUp(self):
        User = get_user_model()
        user = User.objects.create_user('temporary', '[e-mail]', 'temporary')

    def test_secure_page(self):
        User = get_user_model()
        self.client.login(username='temporary', password='temporary')
        response = self.client.get('/manufacturers/', follow=True)
        user = User.objects.get(username='temporary')
        self.assertEqual(response.context['email'], '[e-mail]')
