Django-Allauth未调用自定义注册表单问题求助

我使用Django-Allauth搭配React作为前端，给自定义用户模型添加了name字段，在forms.py中重写了SignupForm以保存该字段，同时按照文档要求在settings.py中配置了：

ACCOUNT_FORMS = {'signup': 'XXXX.forms.CustomSignupForm'}

但注册时自定义表单并未初始化（添加的打印语句无输出），用户虽能创建，但未保存新增的name字段，且前端已正确发送请求体。

forms.py代码 #

class CustomUserCreationForm(UserCreationForm):
    name = forms.CharField(max_length=30, required=True, help_text='Enter your name.')

    class Meta:
        model = CustomUser
        fields = ("email", "name")


class CustomSignupForm(SignupForm):
    name = forms.CharField(max_length=40, required=True, help_text='Enter your name.')
    
    def __init__(self, *args, **kwargs):
        print("CustomSignupForm is being initialized")
        super().__init__(*args, **kwargs)
        
    def save(self, request):
        print("im working")
        user = super().save(request)
        user.name = self.cleaned_data['name']
        user.save()
        return user 

urls.py配置 #

urlpatterns = [
    path("admin/", admin.site.urls),
    path('', include('XXXX.urls')),
    path('accounts/', include('allauth.urls')),
    path("_allauth/", include("allauth.headless.urls")),
]

尝试过的解决方法 #

• 尝试在settings中配置ACCOUNT_ADAPTER，adapters.py代码如下：

class CustomAccountAdapter(DefaultAccountAdapter):
#     def get_signup_form_class(self):
#         return CustomSignupForm

但仍未调用自定义表单。

• 修改过CustomUserManager，但认为表单处理在管理器之前，因此无效果。

翻遍文档都没找到解决方案，恳请帮助！

补充settings.py配置 #
