如何在Django测试框架中修改会话

Question

我的网站允许个人在没有登录的情况下通过基于当前session_key创建用户来贡献内容

我想为我的视图设置一个测试,但似乎无法修改request.session:

我想这样做:

from django.contrib.sessions.models import Session
s = Session()
s.expire_date = '2010-12-05'
s.session_key = 'my_session_key'
s.save()
self.client.session = s
response = self.client.get('/myview/')

但我得到错误:

AttributeError: can't set attribute

关于如何在获取请求之前修改客户端会话的想法？我已经看到了这个,它似乎并没有工作

Answer 1

django测试框架的客户端对象使触摸会话成为可能.请查看http://docs.djangoproject.com/en/dev/topics/testing/?from=olddocs#django.test.client.Client.session了解详情

小心 : To modify the session and then save it, it must be stored in a variable first (because a new SessionStore is created every time this property is accessed)

我认为下面这样的事情应该有效

s = self.client.session
s.update({
    "expire_date": '2010-12-05',
    "session_key": 'my_session_key',
})
s.save()
response = self.client.get('/myview/')

Answer 2

这就是我做到的方式(灵感来自http://blog.mediaonfire.com/?p=36中的解决方案).

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

class SessionTestCase(TestCase):
    def setUp(self):
        # http://code.djangoproject.com/ticket/10899
        settings.SESSION_ENGINE = 'django.contrib.sessions.backends.file'
        engine = import_module(settings.SESSION_ENGINE)
        store = engine.SessionStore()
        store.save()
        self.session = store
        self.client.cookies[settings.SESSION_COOKIE_NAME] = store.session_key

之后,您可以创建测试:

class BlahTestCase(SessionTestCase):

    def test_blah_with_session(self):
        session = self.session
        session['operator'] = 'Jimmy'
        session.save()

等等...

Answer 3

正如安德鲁·奥斯汀已经提到的那样,由于这个错误它不起作用:https://code.djangoproject.com/ticket/11475

你可以做的是:

from django.test import TestCase
from django.test.client import Client
from django.contrib.auth.models import User

class SessionTestCase(TestCase):
    def setUp(self):
        self.client = Client()
        User.objects.create_user('john', 'lennon@thebeatles.com', 'johnpassword')
        self.client.login(username='john', password='johnpassword')

    def test_something_with_sessions(self):
        session = self.client.session
        session['key'] = 'value'
        session.save()

使用User.objects.create_user()和self.client.login()创建并登录用户后,如上面的代码所示,会话应该有效.
