我已在firstname表单中添加lastname和django-registration字段。但注册后我的admin page未显示已注册的first name和last name，但它是空白的，但会显示username和email address。
请阅读以下docstring中提供的source code：
以下是来自RegistrationForm
django-registration的代码

requires the password to be entered twice to catch typos.

saving of collected user data is delegated to the active
registration backend.

<强>更新
您可以将create_inactive_user上的Registration/Models.py更改为这样......
def create_inactive_user(self, username, email, password,
site, send_email=True, first_name=None, last_name=None):
"""
Create a new, inactive ``User``, generate a
``RegistrationProfile`` and email its activation key to the
``User``, returning the new ``User``.
By default, an activation email will be sent to the new
user. To disable this, pass ``send_email=False``.
"""
new_user = User.objects.create_user(username, email, password)
new_user.is_active = False
new_user.first_name = first_name
new_user.last_name = last_name
new_user.save()
registration_profile = self.create_profile(new_user)
if send_email:
registration_profile.send_activation_email(site)
return new_user
请注意，它现在接受first_name和last_name。另请注意new_user.first_name = first_name和new_user.last_name = last_name
然后在Registration/backends/default/views.py上，您希望register看起来像这样......
def register(self, request, **cleaned_data):
username, email, password, first_name, last_name = cleaned_data['username'], cleaned_data['email'], cleaned_data['password1'], cleaned_data['firstname'], cleaned_data['lastname']
if Site._meta.installed:
site = Site.objects.get_current()
else:
site = RequestSite(request)
new_user = RegistrationProfile.objects.create_inactive_user(username, email, password, site, first_name, last_name)
signals.user_registered.send(sender=self.__class__,
user=new_user,
request=request)
return new_user
请注意firstname（表单获取方式）和first_name（这是存储的内容，然后传递给create_inactive_user。

由于method signature
考虑一下：
def create_inactive_user(self, username, email, password,
site, send_email=True, first_name=None, last_name=None):
但在上面的register method中，您可以拨打电话：
new_user = RegistrationProfile.objects.create_inactive_user(username, email, password, site, first_name, last_name)
由于send_email=True是default值，first_name获得的内容会以send_email传递，last_name传递给first_name 。因此，last_name为None。
修复很简单。只需按如下方式更改方法签名：
def create_inactive_user(self, username, email, password,
site, first_name=None, last_name=None, send_email=True):
