Django TestCase 对象没有属性“登录”

Question

我使用 selenium 来测试我的登录方法，它工作正常。 然后，我尝试测试网站的其他部分。 所以，我需要在我的测试中创建一个用户。 为此，我使用了客户端而不是请求工厂（因为有中间件类）。 但是，我收到错误：

AttributeError: 'ProjectListTestCase' object has no attribute 'login'

我确实有一个自定义身份验证后端，以允许使用电子邮件地址而不是用户名：

INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'phonenumber_field',
'rest_framework',

# 3rd party apps
'crispy_forms',

# Local apps 
'accounts',
...

我在控制台中尝试了代码：

>>> the_client = Client()
>>> the_client.login(email='test@testing.com', password='testingPassword')
True

这是我的 test_views.py 中的代码：

from django.core.urlresolvers import reverse
from django.core.exceptions import ObjectDoesNotExist, ValidationError
from django.test import TestCase
from django.test import RequestFactory

from model_mommy import mommy
from selenium import webdriver

from project_profile.models import Project
from user_profile.models import UserProfile

class ProjectListTestCase(TestCase):
    def setUp(self):

        # login the user
        self.login = self.client.login(email='test@testing.com', password='testingPassword')
        print ('Login successful? ', self.login)          # Just to see what's going on

        self.response = self.client.get(reverse('development:list_view_developmentproject') )
        print('response: ', self.response)                # Just to see what's going on


    def test_user_login(self):           
        self.assertEqual(self.response.status_code, 200)

为什么在运行测试时出现错误，但在控制台中使用相同的代码运行良好？

编辑 1：将 setUp 中的登录和响应更改为 self.login 和 self.response 以保持一致性。 我仍然收到一个错误：

TypeError: 'AnonymousUser' object is not iterable

编辑 3：添加DevelopmentProjectList

class DevelopmentProjectList(ListView):
    model = DevelopmentProject
    template_name = 'development/development.html'
    context_object_name = 'development_projects'



    def get_queryset(self, *args, **kwargs):
        logged_in_user = self.request.user
        user_development_projects = DevelopmentProject.objects.filter(project__users = logged_in_user)

        return user_development_projects

Answer 1

正如@Iain Shelvington 在此评论中提到的，您尚未将变量login分配给self

你应该做这样的事情，

class ProjectListTestCase(TestCase):
    def setUp(self):
        # login the user
        self.login = self.client.login(email='test@testing.com', password='testingPassword')
        print('Login successful? ', self.login)  # Just to see what's going on

        self.response = self.client.get(reverse('development:list_view_developmentproject'))
        print('response: ', self.response)  # Just to see what's going on

    def test_user_login(self):
        self.assertEqual(self.response.status_code, 200)

---

更新 1

在您看来，您并没有强制用户登录。 因此，将LoginRequiredMixin混合类添加到您的视图中，如下所示

from django.contrib.auth.mixins import LoginRequiredMixin


class DevelopmentProjectList(LoginRequiredMixin, ListView):
    ...
    # your code

Answer 2

一致地使用login / response或self.login / self.response - 基于您是否想在test_user_login使用它

您在此处分配变量login ：

login = self.client.login(email='test@testing.com', password='testingPassword')

然后尝试在此处访问self.login ：

print ('Login successful? ', self.login)          # Just to see what's going on

同样适用于response和self.response

最终代码可能如下所示：

from django.core.urlresolvers import reverse
from django.core.exceptions import ObjectDoesNotExist, ValidationError
from django.test import TestCase
from django.test import RequestFactory

from model_mommy import mommy
from selenium import webdriver

from project_profile.models import Project
from user_profile.models import UserProfile

class ProjectListTestCase(TestCase):
    def setUp(self):

        # login the user
        self.login = self.client.login(email='test@testing.com', password='testingPassword')
        print ('Login successful? ', self.login)          # Just to see what's going on

        self.response = self.client.get(reverse('development:list_view_developmentproject') )
        print('response: ', self.response)                # Just to see what's going on


    def test_user_login(self):           
        self.assertEqual(self.response.status_code, 200)
