I've configured user's username field in following way

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. This value may contain only '
                  'letters, numbers ' 'and ./+/-/_ characters.')
            ),
        ],
        error_messages={
            'unique': _("A user with that username already exists."),
        },
    )

I'm getting error in admin panel but not in django-shell.

Though django raises an error for maximum length in shell.

Is it a bug? Or am I missing something.

This has nothing to do with being in the shell.

Validators aren't run on save, and that is the case everywhere, as noted explicitly in the validators documentation: https://docs.djangoproject.com/en/1.10/ref/validators/#how-validators-are-run
