Django链接两个应用程序

我目前面临的问题是，我想从我的主应用程序（博客应用程序）中的另一个应用程序（保存用户模型的帐户应用程序）调用视图

这是我得到的错误：

django.core.exceptions.FieldError: Unknown field(s) (username) specified for User

url.py

...
from quickblog import views as core_views
from accounts import views as views_accounts

...
url(r'^myaccount/$', views_accounts.view_profile, name='myaccount'),

views.py（账户应用程序）：

这是我的第一个django应用程序，关于在一个项目中链接两个应用程序，可能有什么我需要知道的吗

---

谢谢

此错误似乎与链接应用程序无关。你怎么会这么认为？你做过迁移吗？显示您的视图.py。此错误似乎未与URL链接。py@Wariored更新。
