Question

也许我要问的问题非常笼统，没有具体的答案。情况是我花了几天时间试图找到答案，我很遗憾。我将不胜感激任何形式的回应或对任何可以帮助我的书籍或手册的参考。

我正在尝试使用测试重新创建Django身份验证过程，我将检查用户的用户和密码。

测试功能代码如下。

import sys, os
import unittest, mock, kiss

from sqlite3 import connect, PARSE_DECLTYPES
from datetime import date

from twisted.python import log
from twisted.cred import credentials
from twisted.cred.error import UnauthorizedLogin

from ampauth.testing import DjangoAuthChecker

"""
Some irrelevant code for this question.
"""

    def test_GoodCredentials(self):
    creds = credentials.UsernamePassword(self.username, self.password)
    checker = DjangoAuthChecker()
    d = checker.requestAvatarId(creds)

其中self.username是用户名，self.password是密码。

当我尝试使用DjangoAuthChecker类创建用户的头像时出现问题。

import os

from zope.interface import implements
from twisted.python import failure, log
from twisted.cred import portal, checkers, error, credentials
from twisted.internet import defer

from django.contrib.auth.models import User

class DjangoAuthChecker():
    implements(checkers.ICredentialsChecker)
    credentialInterfaces = (credentials.IUsernamePassword,
    credentials.IUsernameHashedPassword)

    def _passwordMatch(self, matched, user):
        if matched:
            return user
        else:
            return failure.Failure(error.UnauthorizedLogin())

    def requestAvatarId(self, credentials, connection):
        try:
            user = User.objects.get(username=credentials.username)
            return defer.maybeDeferred(
                check_password,
                credentials.password,
                user.password).addCallback(self._passwordMatch, user)
        except User.DoesNotExist:
            return defer.fail(error.UnauthorizedLogin())

之前的代码在屏幕上显示以下错误。

(.venv_test)sgongar@debian8-64bits-dev:~/Dev/client/protocol/tests$ python test_creds.py

    % (desc, ENVIRONMENT_VARIABLE))
django.core.exceptions.ImproperlyConfigured: Requested setting CACHES, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

所以问题是，我可能需要一个设置文件才能使用单个django类吗？我以为我可以在不需要设置文件的情况下导入一个类。

如何用模拟对象替换设置文件？

解决

好吧，我添加了几行来配置设置，我设法避免了错误。现在我有另一个问题，即为用户创建表格，但会将问题发布在另一页面上。

from django.conf import settings

settings.configure(DEBUG=True, 
                    DATABASES = {'default': {'ENGINE': 'django.db.backends.sqlite3',
                    'NAME': os.path.join(BASE_DIR, 'test.db'),
                    'TEST_NAME': os.path.join(BASE_DIR, 'test.db'),}},
                    INSTALLED_APPS = ('django.contrib.auth',))

from django.contrib.auth.models import User, check_password
from django.db import models

在模拟补丁的测试中使用django类

解决
