Django TestCase对象没有属性'；登录'；

我已经使用selenium测试了我的登录方法，它运行良好。然后，我试着测试网站的其他部分。所以，我需要在测试中创建一个用户。为此，我使用了客户机而不是请求工厂（因为有中间件类）。但是，我得到了一个错误：

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

我有一个自定义的身份验证后端，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以下代码：

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

以下是我的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)

为什么运行测试时会出现错误，但在控制台中使用相同的代码运行正常

编辑1:将设置中的登录和响应更改为self.login和self.response以保持一致性。我仍然得到一个错误：

TypeError: 'AnonymousUser' object is not iterable

编辑2:完全回溯：

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

如前所述，您尚未将变量

分配给

self

你应该这样做

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)

---

使用

login

/

response

或

self.login

/

self.response

，根据您是否想在

测试用户登录时使用

您在此处分配变量
login
：

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

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

然后尝试访问
self.login
此处：

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

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

同样适用于
response
和
self.response

最终代码可以类似于：

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)

print（'Login successful？'，self.Login）
您没有将Login分配给
self
它只是一个局部变量。您需要将其分配给
self
（
self.login=self.client.login（…）
），或者不将其作为
self'
（
print（'login successful？'.login）
）上的属性引用同样适用于
self.response
虽然应该将login更改为self.login，但它对实际登录过程没有影响。login
self.client.login
应该返回True或False，而不管您将其放置在哪里，login或self.login。从那时起，self.client应该经过身份验证，以返回状态为200的响应。我确实按照您的建议更改了我的代码，但我仍然收到一个错误：
TypeError:“AnonymousUser”对象不可编辑
虽然登录应更改为self.login，但它对实际登录过程没有影响。login
self.client.login
应返回True或False，无论您将其放置在何处，login或self.login.From然后，self.client应该经过身份验证，以返回一个状态代码为200的响应。我确实按照您的建议更改了代码，但仍然得到一个错误：
TypeError:“AnonymousUser”对象不可编辑
它对登录过程没有影响，但对您在原始帖子中提到的错误有影响。@Early编码器，无论哪种方式，您都应该添加完整的错误回溯您注意到一个错误是正确的，
AttributeError:'ProjectListTestCase'对象没有属性'login'
但是，主要错误是由于登录：
TypeError:'AnonymousUser'对象不可编辑
我将更新您的答案，因为它成功地调试了一个错误，但我仍将等待解决主要错误的答案。因此，我没有包含修饰的分派方法。因此，使用mixin的替代方法是使用
@method\u decorator（需要登录）
在分派时。由于我的同一代码在其他项目中工作，因此很难调试，并且我无法找出导致错误的原因。非常感谢您花时间找出根本原因。
