Pycharm 3.4.1 - "AppRegistryNotReady:模型尚未加载".Django Rest framewrok

Question

我使用的是DRF和Pycharm 3.4.1和Django 1.7.当我尝试通过Pycharm django控制台测试我的序列化程序类时,它给出了以下错误:

码

from items_app.serializers import ItemSerializer
s = ItemSerializer()
print(repr(s))

然后导致以下错误回溯:

AppRegistryNotReady: Models aren't loaded yet.

但是当我使用我的终端(而不是pycharm django控制台)时,它正常工作!我知道有问题,Pycharm但我不知道如何解决它!

加载应用程序注册表是该django.setup方法的一部分.如果当您开始使用控制台不加载应用程序的注册表,最可能的原因是,它是一个普通的Python控制台,而不是一个完全成熟的Django控制台.

请尝试以下代码.如果这解决了它,你确实使用普通的python控制台.

>>> import django
>>> django.setup()
