django – HttpRequest对象没有属性’session’

我似乎无法让会议工作. Django抱怨HttpRequest对象没有名为’session’的属性.在文档中,它清楚地表明,如果您启用了中间件,并且已安装的应用程序中包含 django.contrib.sessions,那么您就可以开始了.我使用单元测试得到这个错误.

在我的views.py中：

def home_page(request):
    response = render(request,'home.html',{'message_text' : request.session.get('message_text',''),'ip_address'    :   request.session.get('ip_address','port_number'   :   request.session.get('port_number','command_text'  :   request.session.get('command_text',})

    request.session['message_text'] = ''

    return response

我试图获得的会话值是我试图在views.py中的其他地方的表单post方法中设置的.

它还声明在新项目上默认启用这些.所以我创建了一个全新的django项目并在控制台中检查了session属性.这正是我所做的：

(django1.5)Python $django-admin.py startproject testing
(django1.5)Python $cd testing/
(django1.5)testing $python manage.py shell
Python 2.7.3 (v2.7.3:70274d53c1dd,Apr  9 2012,20:52:43)

>>> from django.http import HttpRequest
>>> r = HttpRequest()
>>> r.session
Traceback (most recent call last):
  File "<console>",line 1,in <module>
AttributeError: 'HttpRequest' object has no attribute 'session'
>>>

我错过了什么？

更新：这仅在使用单元测试进行测试时才会发生.以下是导致异常的测试：

def test_home_page_returns_correct_html(self):
        request = HttpRequest()
        response = home_page(request)
        expected_html = render_to_string('home.html')
        self.assertEqual(response.content,expected_html)

from django.conf import settings
from django.utils.importlib import import_module

def test_home_page_returns_correct_html(self):
    request = HttpRequest()
    engine = import_module(settings.SESSION_ENGINE)
    session_key = None
    request.session = engine.SessionStore(session_key)
    response = home_page(request)
    expected_html = render_to_string('home.html')
    self.assertEqual(response.content,expected_html)
