Question

我有一个小的django应用程序，它允许显示与用户相关的一些信息。这个信息存储在sqlite中，我很好。用户的登录名和密码存储在另一个oracle数据库中，我的问题是：如何使用存储在oracle db中的creditinals来授权用户？我想，直接访问db（select）会没问题，因为不能更改oracle db中的数据。还有另外一个问题：如何存储django超级用户数据？提前谢谢。

有关如何在此处使用oracle数据库的信息：https://docs.djangoproject.com/en/1.8/ref/databases/#oracle-notes

另外，这里有一个关于如何使用自定义身份验证后端的好例子：

https://djangosnippets.org/snippets/1678/

from django.contrib.auth.models import User
from django.conf import settings
import cx_Oracle

# set in config or here depending on your taste
try:
    ORACLE_CONNECT = settings.ORACLE_CONNECT
except:
    ORACLE_CONNECT = None

# when using runserver I turn debugging on, you can
# set to false of remove.
try:
    DEBUG = settings.DEBUG
except:
    DEBUG = False

class OracleAuthBackend:
    """
    This class is used to authenticate against an Oracle database and
    adds a user if authentication is successful.  It uppercases the
    username since oracle usernames are not currently case sensitive.
    Additionally I append _ORACLE to the username to help make it
    easier to identify what auth source was used and to avoid conflicts
    with ldap authenticated sessions.
    """
    def authenticate(self, username=None, password=None):
        if DEBUG:
            print "Attempting to log in as %s" % (username)
        if ORACLE_CONNECT == None:
            constr = '%s/%s' % (username, password)
        else:
            constr = '%s/%s@%s' % (username, password, ORACLE_CONNECT)
        try:
            auth_con = cx_Oracle.connect(constr.encode('ascii','ignore'))
            auth_con.close()
        except Exception, e:
            if DEBUG:
                print e
            return None
        oracle_user = username.upper() + '_ORACLE'
        try:
            if DEBUG:
                print 'Looking up: %s' % oracle_user
            user = User.objects.get(username=oracle_user)
        except:
            if DEBUG:
                print 'Adding user: %s' % oracle_user
            user = User(username=oracle_user)
            user.set_unusable_password()
            try:
                user.save()
            except:
                if DEBUG:
                    print "ERROR: adding %s" % oracle_user
                return None
        return user

    def get_user(self, user_id):
        try:
            return User.objects.get(pk=user_id)
        except User.DoesNotExist:
            return None

复制代码...以供参考。没有经过我的测试。我对oracle数据库了解不多。希望这会有所帮助...

默认情况下，Django支持多个数据库。官方documentation附带了大量示例，也符合您的标准。

您可以使用Database routers指示Django使用哪个数据库进行身份验证。

直接访问数据库以便在django中进行身份验证
