用于添加用户的等效get_or_create

Question

添加用户的方式是否比使用以下模式更简单？

    try:
        new_user = User.objects.create_user(username, email, password)
    except IntegrityError:
        messages.info(request, "This user already exists.")
    else:
        new_user.first_name = first_name
        # continue with other things

Answer 1

在Django 1.4中,用户存在get_or_create().

from django.contrib.auth.models import User

_user = User.objects.get_or_create(
        username=u'bob',
        password=u'bobspassword',
    )

Answer 2

最好不要IntegrityError因为其他原因而抓住它.您需要检查用户是否存在,不包括密码.如果用户已存在,请设置密码.

user, created = User.objects.get_or_create(username=username, email=email)
if not created:
    user.set_password(password)

Answer 3

我不这么认为。但是您可以代理 Django 用户：

class MyUser(User):
    class Meta:
        proxy = True

    def get_or_create(self, username, email, password, *args, **kwargs):
        try:
            new_user = User.objects.create_user(username, email, password)
        except IntegrityError:
            return User.objects.get(username=username, email=email)
        else:
            new_user.first_name = kwargs['first_name'] # or what you want
            ...etc...

        return new_user
