如何在Django用户名中允许空格？ [英] How can I allow spaces in a Django username?

问题描述

我试图在Django应用中允许用户名中的空格。这是从我的形式：

I'm trying to allow spaces in usernames in my Django app. This is from my form:

class SignUpForm(django.forms.ModelForm):
...
    username = django.forms.RegexField(
       regex=r'^[a-zA-Z]{1}[a-zA-Z -]{1,29}$'

我希望以一个字母开头的用户名，然后我允许使用字母和空格和连字符。 我不知道为什么，其他地方的空格有限制吗？

I want username to start with a letter. After that I allow letters and spaces and hyphens. Somehow the form fails validation with "John Smith" and I have no idea why. Is there a restriction on spaces somewhere else?

推荐答案

django auth用户基于抽象用户类（django.contrib.auth.models）。您的绑定表单可能是有效的，但如果您尝试保存用户对象验证失败。

the django auth user is based on an abstract user class (django.contrib.auth.models). Your bound form may be valid, but if you try to save the user object validation fails.

查看来自django.contrib.auth.models的用户名：

Have a look at the source from django.contrib.auth.models regarding the username:

class AbstractUser(AbstractBaseUser, PermissionsMixin):
    """
An abstract base class implementing a fully featured User model with
admin-compliant permissions.

Username, password and email are required. Other fields are optional.
"""
    username = models.CharField(_('username'), max_length=30, unique=True,
        help_text=_('Required. 30 characters or fewer. Letters, digits and '
                    '@/./+/-/_ only.'),
        validators=[
            validators.RegexValidator(r'^[\w.@+-]+$', _('Enter a valid username.'), 'invalid')
        ])

希望对此有所了解。
