jay*_*l d 2 django django-models
我正在使用Django1.4和PostgreSQL.我正在开发一个应用程序,其中我有两个模型,即学生,公司.
class students(models.Model):
first_name = models.CharField(**option)
last_name = models.CharField(**option)
username = models.EmailField(max_length=100, unique=True)
password = models.CharField(_('password'), max_length=128)
# Some other attributes for Student models
class company(models.Model):
compnay_name = models.CharField(**option)
username = models.EmailField(max_length=100, unique=True)
password = models.CharField(_('password'), max_length=128)
#Some other attributes for company models

由于我没有使用或扩展用户模型,我无法使用django内置登录和身份验证方法.
如何编写自定义身份验证方法,该方法应检查学生/公司用户名和密码中的用户凭据.(为学生和公司提供2种不同的登录表格)
请帮我.
感谢您阅读我的查询.
class LoginBackend:
def authenticate(self, username=None, password=None, model=None):
if model == "Student":
lookup_model = Student
elif model == "Employer":
lookup_model = Employer
try:
user = lookup_model.objects.get(email=username)
except Exception, e:
return None
return user

def check_auth(request):
user_object = Student.objects.get(email__iexact = unicode(email))
if check_password(password, user_object.password):
print authenticate(username = email, password = password, model = "Student")
login(request, user_object)

/xx/login /的AttributeError
'学生'对象没有属性'后端'
编写自定义身份验证后端.读这个:
[更新]
通过编写和注册自定义身份验证后端,您只需使用标准的Django身份验证模式.看看你的示例代码,我的印象是你对它有不同的理解.
由于电子邮件是您的唯一密钥,我建议使用电子邮件登录密钥,首先检查针对学生的登录名/密码,如果失败,请查看公司.
from django.contrib.auth.models import User
class JayapalsBackend(object):
def authenticate(self, username=None, password=None):
try:
o = Student.objects.get(email=username, password=password)
except Student.DoesNotExist:
try:
o = Company.objects.get(email=username, password=password)
except Company.DoesNotExist:
return None
return User.objects.get(email=o.email)
def get_user(self, user_id):
try:
return User.objects.get(pk=user_id)
except User.DoesNotExist:
return None

然后只使用标准的Django装饰器:
@login_required
def some_private_view(request):
