????????send_mail(subject,?message,?from_email,?[self.email],?**kwargs)第一：像first_name?=?models.CharField(_('first?name'),?max_length=30,?blank=True)
和
verbose_name?=?_('user')里面添加的? ?_?? 是什么意思呀，一般我都寫(xiě)成first_name?=?models.CharField(max_length=30,?blank=True)
和
verbose_name?=?user第二：USERNAME_FIELD?=?'username'
REQUIRED_FIELDS?=?['email']上面的寫(xiě)的什么意思呢？
求助：python源代碼解讀
