在项目中导入tastypie

Question

我正在学习如何使用 tastypie，并且我通过命令 sudo pip install django-tastypie 安装了它。

我想试一下：

from tastypie.resources import ModelResource
from tastypie.resources import ALL
from models import Article

但是我得到了：

Traceback:

你可能忘记了两件事：

1) 在你的 setting.py 文件中，把 tastypie 加入到已安装的应用列表里。

INSTALLED_APPS = (
    .....
    'tastypie',


)

或者

2) 你可能在 env 环境之外安装了 tastypie。
