Django Allauth:如何在注册表单上添加更多自定义字段？

# models.py
from django.contrib.auth.models import AbstractUser
from django.db import models

class CustomUser(AbstractUser):
    # 添加自定义字段
    custom_field = models.CharField(max_length=100)

# settings.py
AUTH_USER_MODEL = 'your_app.CustomUser'
ACCOUNT_SIGNUP_FORM_CLASS = 'your_app.forms.CustomSignupForm'

# forms.py
from django import forms
from allauth.account.forms import SignupForm

class CustomSignupForm(SignupForm):
    # 添加自定义字段
    custom_field = forms.CharField(max_length=100)

    def save(self, request):
        user = super().save(request)
        # 保存自定义字段的值到用户模型
        user.custom_field = self.cleaned_data['custom_field']
        user.save()
        return user

# signals.py
from allauth.account.signals import user_signed_up
from django.dispatch import receiver

@receiver(user_signed_up)
def save_custom_field(sender, request, user, **kwargs):
    # 保存自定义字段的值到用户模型
    user.custom_field = request.POST.get('custom_field')
    user.save()
