Django测试客户端不会创建用户对象，但会创建一个匿名用户对象

Question

我已经为我的项目实现了用户注册，并且我确实能够从Django shell客户端中找到使用User.objects.get（）创建的对象。

但是在运行测试时，似乎创建了AnonymousUser对象而不是User对象。

我有以下代码;

forms.py;

from django import forms 
from django.contrib.auth.models import User 
from django.contrib.auth.forms import UserCreationForm 

class UserCreateForm(UserCreationForm): 
    """ 
    Extends Django's UserCreationForm 
    """ 
    email_exists_message = "A user with that email id already exists." 
    email = forms.EmailField(required=True) 
    first_name = forms.CharField(required=True) 
    last_name = forms.CharField() 

    class Meta: 
     model = User 
     fields = ("first_name", "last_name", "username", "email", "password1", "password2") 

    def clean_email(self): 
     email = self.cleaned_data["email"] 
     try: 
      User._default_manager.get(email=email) 
     except User.DoesNotExist: 
      return email 
     raise forms.ValidationError(
      self.email_exists_message, 
      code='duplicate_email', 
     ) 

    def save(self, commit=True): 
     user = super(UserCreateForm, self).save(commit=False) 
     user.email = self.cleaned_data["email"] 
     user.first_name = self.cleaned_data["first_name"] 
     user.last_name = self.cleaned_data["last_name"] 
     if commit: 
      user.save() 
     return user 

urls.py;

. 
. 
. 
from stationrunner.forms import UserCreateForm 
. 
. 

urlpatterns = patterns('', 
    url('^registration/', 
     CreateView.as_view(template_name='auth/register.html', 
         form_class=UserCreateForm, 
         success_url='/stations/create' 
     ), 
     name='userregistration' 
    ), 
    . 
    . 
    . 
) 

and finally my tests.py;

from django.test import TestCase 
from django.core.urlresolvers import reverse 
from django.contrib.auth.models import User 

class TestUserSignUp(TestCase): 
    . 
    . 
    . 
    def test_submission_form_creates_user_object(self): 
    """ 
    Tests if submission of the form on page for creation of a 
    user creates a user object and its attributes take the 
    expected values 
    """ 
    first_name = "somename" 
    last_name = "somename" 
    email = "someemail@someservice.com" 
    username = "someusername" 
    password = "somepassword" 
    response = self.client.post(reverse("userregistration"), 
           {"first_name": first_name, 
           "last_name": last_name, 
           "email": email, 
           "username": username, 
           "password": password}, 
           follow=True) 
    assert "user" in response.context 
    user = response.context["user"] 
    assert user.first_name == first_name 
    assert user.last_name == last_name 
    assert user.email == email 
    assert user.username == username 
    assert user.password == user.set_password(password) 

如上用户对象说确实得到保存到数据库和我进一步确信它使用userobject.is_authenticated（）从Django的壳

但是当我运行我的测试，我得到以下故障

>  assert user.first_name == first_name 

stationrunner/tests.py:145:

self = <SimpleLazyObject: <django.contrib.auth.models.AnonymousUser  object at 0x7f815ac211d0>>, args = ('first_name',) 

    def inner(self, *args): 
     if self._wrapped is empty: 
      self._setup() 
>  return func(self._wrapped, *args) 
E  AttributeError: 'AnonymousUser' object has no attribute 'first_name' 

我是新手到Python/Django和我非常期待着有人向我解释这是怎么发生的

更新;

我导入了身份验证并登录到了我的forms.py，并将save（）方法改为看起来像;

def save(self, commit=True): 
    user = super(UserCreateForm, self).save(commit=False) 
    user.email = self.cleaned_data["email"] 
    user.first_name = self.cleaned_data["first_name"] 
    user.last_name = self.cleaned_data["last_name"] 
    if commit: 
     user.save() 
     authenticate(username=user.username, password=user.password) 
     log_user_in(user) 
    return user 

并添加了预期的log_user_in（）方法为;

def log_user_in(self, user): 
    login(self.request, user) 

我试图登录用户，因此期望我的response.context不包含匿名用户对象，但包含用户对象本身。

但代码似乎不起作用。我仍然得到同样的错误。正如已经说过的我是一个新手，所以请原谅，如果有任何愚蠢。

您正在创建一个新用户，但您没有以该用户身份进行身份验证。因此，您从response.context读取的用户是AnonymousUser。

如果您确实想在创建时登录用户，最好的方法可能是创建您自己的表单视图。

否则，您必须更改测试以从数据库中读取新创建的用户。
