我收到属性错误：当我尝试运行服务器并进行迁移时'SubscriptionForm'对象没有属性'model'

Question

当我运行python manage.py runserver或makegration时，我会遇到这个回溯问题。我哪里错了？请帮忙。我"我也在试着把这个添加到管理网站上。谢谢

这实际上起过一次作用，所以我不确定我做错了什么，或者我做了什么改变才出现了这个错误。

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

管理员.py

from django.contrib import admin
from .models import Profile, Subscription
admin.site.register(Profile, Subscription)

当导入Subscription和SubscriptionForm 时，我仍然会得到相同的属性错误

Answer 1

您应该从模型导入并分别传递模型：

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。将导入和文件路径添加到问题中。

Answer 2

注册模型的工作方式不同。不在同一行admin.site.register(配置文件，订阅(

from django.contrib import admin
from .models import Profile, Subscription
admin.site.register(Profile)
admin.site.register(Subscription)
