Django rest-auth allauth注册电子邮件，名字和姓氏，没有用户名

Question

我正在使用django-rest-auth和allauth在我的django应用程序中登录和注册。我没有为登录或注册编写任何额外的单行代码。使用emailid和提供的密码注册成功。

我不使用用户名进行身份验证，而是使用电子邮件

在我可浏览的注册api中，我得到以下内容：

除了这些字段，我想要first_name和last_name（默认的auth_user表有这些列），这样我新创建的auth_user也会设置这些字段以及电子邮件和散列密码。

我怎样才能做到这一点？这个可浏览的表单本身并不那么重要，但能够存储first_name和last_name是我主要需要的。

Answer 1

1. 确保你的ACCOUNT_USERNAME_REQUIRED = False文件中有settings.py。
2. 对于first_name和last_name你需要写一个自定义RegisterSerializer（https://github.com/Tivix/django-rest-auth/blob/master/rest_auth/registration/serializers.py#L166）

这是serializers.py的示例代码

from allauth.account import app_settings as allauth_settings
from allauth.utils import email_address_exists
from allauth.account.adapter import get_adapter
from allauth.account.utils import setup_user_email

class RegisterSerializer(serializers.Serializer):
    email = serializers.EmailField(required=allauth_settings.EMAIL_REQUIRED)
    first_name = serializers.CharField(required=True, write_only=True)
    last_name = serializers.CharField(required=True, write_only=True)
    password1 = serializers.CharField(required=True, write_only=True)
    password2 = serializers.CharField(required=True, write_only=True)

    def validate_email(self, email):
        email = get_adapter().clean_email(email)
        if allauth_settings.UNIQUE_EMAIL:
            if email and email_address_exists(email):
                raise serializers.ValidationError(
                    _("A user is already registered with this e-mail address."))
        return email

    def validate_password1(self, password):
        return get_adapter().clean_password(password)

    def validate(self, data):
        if data['password1'] != data['password2']:
            raise serializers.ValidationError(
                _("The two password fields didn't match."))
        return data

    def get_cleaned_data(self):
        return {
            'first_name': self.validated_data.get('first_name', ''),
            'last_name': self.validated_data.get('last_name', ''),
            'password1': self.validated_data.get('password1', ''),
            'email': self.validated_data.get('email', ''),
        }

    def save(self, request):
        adapter = get_adapter()
        user = adapter.new_user(request)
        self.cleaned_data = self.get_cleaned_data()
        adapter.save_user(request, user, self)
        setup_user_email(request, user, [])
        user.profile.save()
        return user

3. 在settings.py中，请确保添加以引用新的Serializer。

   REST_AUTH_REGISTER_SERIALIZERS = {
           'REGISTER_SERIALIZER': 'path.to.RegisterSerializer',
   }

您也可以在custom_signup上覆盖用于此目的的RegisterSerializer方法。

from rest_auth.registration.serializers import RegisterSerializer
from rest_auth.registration.views import RegisterView
from rest_framework import serializers


class NameRegistrationSerializer(RegisterSerializer):

  first_name = serializers.CharField(required=False)
  last_name = serializers.CharField(required=False)

  def custom_signup(self, request, user):
    user.first_name = self.validated_data.get('first_name', '')
    user.last_name = self.validated_data.get('last_name', '')
    user.save(update_fields=['first_name', 'last_name'])


class NameRegistrationView(RegisterView):
  serializer_class = NameRegistrationSerializer

然后在你的urls.py中使用以下内容

url(r'^rest-auth/registration/name-registration/$', NameRegistrationView.as_view(), name="rest_name_register")

或者在REGISTER_SERIALIZER中设置settings.py

REST_AUTH_REGISTER_SERIALIZERS = {
    'REGISTER_SERIALIZER': 'path.to.RegisterSerializer',
}

更优雅的解决方案是从RegisterSerializer继承并根据需要进行扩展。

class MyRegisterSerializer(RegisterSerializer):
    first_name = serializers.CharField(required=True, write_only=True)
    last_name = serializers.CharField(required=True, write_only=True)

    def get_cleaned_data(self):
        return {
            'first_name': self.validated_data.get('first_name', ''),
            'last_name': self.validated_data.get('last_name', ''),
            'password1': self.validated_data.get('password1', ''),
            'email': self.validated_data.get('email', ''),
        }

    def save(self, request):
        adapter = get_adapter()
        user = adapter.new_user(request)
        self.cleaned_data = self.get_cleaned_data()
        adapter.save_user(request, user, self)
        setup_user_email(request, user, [])
        user.save()
        return user
