I get AttributeError: 'SubscriptionForm' object has no attribute 'model' when I try runserver and makemigrations

Question

当我执行 python manage.py runserver 或 makegrations 时，我遇到了这个回溯问题。我哪里出错了？请帮忙。我也在尝试将其添加到管理站点。谢谢

这实际上工作了一次，所以我不确定我做错了什么或者我做了什么导致这个错误出现。

我已经追溯了我的步骤，可以说当我尝试将订阅模型注册到管理页面时会发生这种情况。我应该从进口 .models 导入订阅或 .forms 导入 SubscriptionForm?

admin.py

from django.contrib import admin

from .models import Profile, Subscription

admin.site.register(Profile, Subscription)

我在导入 Subscription 和 SubscriptionForm 时仍然遇到相同的属性错误

Answer 1

注册模型的方式不同。不在同一行 admin.site.register（个人资料，订阅）

from django.contrib import admin

from .models import Profile, Subscription

admin.site.register(Profile)
admin.site.register(Subscription)

Answer 2

您应该从模型中导入并单独传递模型：

admin.site.register(Profile)
admin.site.register(Colaborador)

register() 的第二个参数是 ModelAdmin。

我不确定这是否足够。将您的导入和文件路径添加到问题中。
