员工没有在Django-allauth自定义注册表单中更新

from django import forms
from allauth.account.forms import SignupForm
from .models import Employee  # 假设Employee是员工模型

class CustomSignupForm(SignupForm):
    # 添加自定义字段
    employee_id = forms.CharField(max_length=20, label='员工ID')
    department = forms.CharField(max_length=50, label='部门')

    def save(self, request):
        # 保存自定义字段到员工模型
        user = super().save(request)
        employee = Employee.objects.create(
            user=user,
            employee_id=self.cleaned_data['employee_id'],
            department=self.cleaned_data['department']
        )
        return user

ACCOUNT_FORMS = {
    'signup': 'your_app_name.forms.CustomSignupForm',
}
