Question

我正在尝试设置自定义用户模型，但在尝试验证成员时，我的登录页面上出现以下错误

ImportError at /members/login/ cannot import name check_password

我知道check_password方法存在，但不确定我缺少什么。尝试导入时我在做什么呢？

/members/backends.py

from django.conf import settings
# failing to import check_password here
from django.contrib.auth.models import check_password
from members.models import Member


class EmailAuthBackend(object):
    """Custom authentication backend the allows users to log in using
    their email address."""

    def authenticate(self, email=None, password=None):
        """Authentication method."""
        try:
            member = Member.objects.get(email=email)
            if member.check_password(password):
                return member
        except Member.DoesNotExist:
            return None

mebers / views.py

from django.shortcuts import render_to_response, redirect
from django.template import RequestContext
from django.contrib.auth import login as django_login, authenticate, logout as django_logout

from members.forms.login import LoginForm
from members.forms.register import RegisterForm

def login(request):
    """Login view."""
    if request.method != 'POST':
        form = LoginForm()

    form = LoginForm(data=request.POST)

    if form.is_valid():
        member = authenticate(email=request.POST.get('email'),
                              password=request.POST.get('password1'))
        if member is not None:
            if member.is_active:
                django_login(request,  member)
                return redirect('/')
    else:
        form = LoginForm()

    return render_to_response('members/login.html', {
        'form': form
    }, context_instance=RequestContext(request))

你似乎对功能和方法有点困惑。 check_password是auth.models.User类的一个方法;你不能自己导入它。而你无论如何都不能使用它;你在你自己的成员班上调用 - 完全独立的 - check_password方法;没有必要在那里进口任何东西。

尝试一下：

from django.contrib.auth.hashers import check_password

Django：无法导入名称check_password
