Django社会认证在创建配置文件时不返回first_name和last_name

Question

我使用自定义用户模型来维护django 1.5的用户详细信息，下面是我的代码。当使用社会验证时，一切似乎都工作得很好，接受first_name和last_name。

在我的table表结构中，我没有first_name和last_name，相反，我有一个字段全名。

但是，我在管理器中创建了一个方法来接受姓和名并合并它们。但是，仍然收到空值，关于为什么会发生这种情况的任何建议?

class UserManager(BaseUserManager):
    """
    UserManager()
    """
    def create_user(self, username, email=None, password=None, first_name='', last_name='', **extra_fields):
        if not username:
            raise ValueError('Users must have a username')
        user = self.model(
            username=username,
            email=UserManager.normalize_email(email),
            full_name='%s %s' % (first_name, last_name),
        )
        user.set_password(password)
        user.save(using=self._db)
        return user

class User(AbstractBaseUser, PermissionsMixin):
    """
    Accounts/User
    """
    GENDERS = (
        (u'M', _('Male')),
        (u'F', _('Female')),
    )

    username = models.CharField(_('username'), max_length=30, unique=True,
        help_text=_('Required. 30 characters or fewer. Letters, numbers and '
                    '@/./+/-/_ characters'),
        validators=[
            validators.RegexValidator(re.compile('^[w.@+-]+$'), _('Enter a valid username.'), 'invalid')
        ])

    email           = models.EmailField(_('email address'), blank=True)

    is_staff = models.BooleanField(_('staff status'), default=False,
        help_text=_('Designates whether the user can log into this admin '
                    'site.'))
    is_active = models.BooleanField(_('active'), default=True,
        help_text=_('Designates whether this user should be treated as '
                    'active. Unselect this instead of deleting accounts.'))
    date_joined = models.DateTimeField(_('date joined'), default=timezone.now)
    # user details and information
    full_name           = models.CharField(_('full name'), max_length=30, )
    date_of_birth       = models.DateField(_('birthday'), null=True, blank=True)
    bio                 = models.TextField(_('biography / about you'), null=True, blank=True, help_text=_('Biography / About you'))
    gender              = models.CharField(_('gender'), max_length=1, blank=True, null=True, choices=GENDERS)
    # follows / followers
    followings           = models.ManyToManyField('self', through='Relationship', symmetrical=False, related_name='followers')
    objects             = UserManager()
    USERNAME_FIELD = 'username'
    REQUIRED_FIELDS = ['email', 'date_of_birth', 'full_name',]

Django-social-auth在创建用户时不是这样工作的，而是在你的管理器中调用create_user时，它只是传递用户名和电子邮件，正如你在这里看到的。稍后在管道中，当调用它时，会更新用户模型中的更多字段，但正如代码所述，它执行getattr(user, name, None)，在您的first_name和last_name的情况下，返回None，因为这些字段未在您的模型中定义。

你可以通过在你的模型中定义一些属性来欺骗系统，像这样:

class User(...):
    @property
    def first_name(self):
        if not hasattr(self, '_first_name'):
            self._first_name = self.full_name.split(' ', 1)[0]
        return self._first_name
    @first_name.setter
    def first_name(self, value):
        self._first_name = value
        self.build_full_name()
    @property
    def last_name(self):
        if not hasattr(self, '_last_name'):
            self._last_name = self.full_name.split(' ', 1)[-1]
        return self._last_name
    @first_name.setter
    def last_name(self, value):
        self._last_name = value
        self.build_full_name()
    def build_full_name(self):
        self.full_name = ' '.join([self._first_name, self._last_name])
