为什么名字和姓氏字段没有保存在 django-registration 中？

Question

我在django-registration 表单中包含了firstname 和lastname 的字段。但是注册后我的admin page没有显示注册的first name和last name，它是空白的，但显示username和email address。

请阅读下面source code 中提供的docstring：

这是来自django-registration的RegistrationForm的代码

from django.contrib.auth.models import User
from django import forms
from django.utils.translation import ugettext_lazy as _

    Validates that the requested username is not already in use, and
    requires the password to be entered twice to catch typos.

    Subclasses should feel free to add any additional validation they
    need, but should avoid defining a ``save()`` method -- the actual
    saving of collected user data is delegated to the active
    registration backend.

Answer 1

由于 teewuane 提到的更正后现在无法正常工作是因为method signature

考虑一下：

def create_inactive_user(self, username, email, password,
                         site, send_email=True, first_name=None, last_name=None):

但是在上面的register method你打个电话：

new_user = RegistrationProfile.objects.create_inactive_user(username, email, password, site, first_name, last_name)

因为send_email=True 是default 的值，所以first_name 得到的任何东西都会作为send_email 传入，last_name 会传递给first_name。因此，您将拥有last_name 作为None。

修复很简单。只需将方法签名更改如下：

def create_inactive_user(self, username, email, password,
                             site, first_name=None, last_name=None, send_email=True):

Answer 2

更新：

您可以将Registration/Models.py 上的create_inactive_user 更改为如下所示...

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。还要注意new_user.first_name = first_name 和new_user.last_name = last_name

然后在 Registration/backends/default/views.py 上，您会希望 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

注意firstname（这是您的表单获取它的方式）和first_name（这是存储的内容，然后传递给create_inactive_user。
