如何在Django中创建用户？

Question

我正在尝试通过以下代码在Django项目中创建一个新用户,但突出显示的行会触发异常.

def createUser(request):
    userName = request.REQUEST.get('username', None)
    userPass = request.REQUEST.get('password', None)
    userMail = request.REQUEST.get('email', None)

    # TODO: check if already existed

    **user = User.objects.create_user(userName, userMail, userPass)**
    user.save()

    return render_to_response('home.html', context_instance=RequestContext(request))

有帮助吗？

Answer 1

在Django中创建用户的正确方法是使用create_user函数.这将处理密码的散列等.

from django.contrib.auth.models import User
user = User.objects.create_user(username='john',
                                 email='jlennon@beatles.com',
                                 password='glass onion')

Answer 2

你确认你传递的是实际值而不是None吗？

from django.shortcuts import render

def createUser(request):
    userName = request.REQUEST.get('username', None)
    userPass = request.REQUEST.get('password', None)
    userMail = request.REQUEST.get('email', None)

    # TODO: check if already existed
    if userName and userPass and userMail:
       u,created = User.objects.get_or_create(userName, userMail)
       if created:
          # user was created
          # set the password here
       else:
          # user was retrieved
    else:
       # request was empty

    return render(request,'home.html')

批量用户创建 set_password

我正在创建几个测试用户,bulk_create速度要快得多,但我们不能使用create_user它.

set_password 是另一种生成散列密码的方法:

def users_iterator():
    for i in range(nusers):
        is_superuser = (i == 0)
        user = User(
            first_name='First' + str(i),
            is_staff=is_superuser,
            is_superuser=is_superuser,
            last_name='Last' + str(i),
            username='user' + str(i),
        )
        user.set_password('asdfqwer')
        yield user

class Command(BaseCommand):
    def handle(self, **options):
        User.objects.bulk_create(iter(users_iterator()))

如果您正常创建用户，则将无法登录，因为密码创建方法可能有所不同。您可以使用默认的注册表单

from django.contrib.auth.forms import UserCreationForm

您也可以扩展

from django.contrib.auth.forms import UserCreationForm

class UserForm(forms.ModelForm):
    mobile = forms.CharField(max_length=15, min_length=10)
    email = forms.EmailField(required=True)
    class Meta:
        model = User
        fields = ['username', 'password', 'first_name', 'last_name', 'email', 'mobile' ]

然后在视图中使用此类

class UserCreate(CreateView):
    form_class = SignUpForm
    template_name = 'registration/signup.html'
    success_url = reverse_lazy('list')

    def form_valid(self, form):
        user = form.save()
