Question

我正在使用DRF和Pycharm 3.4.1以及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：

代码

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

然后导致以下错误追溯：

    raise AppRegistryNotReady("Models aren't loaded yet.")
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Pycharm存在问题，但我不知道如何修复它！

加载app注册表是django.setup方法的一部分。如果在开始使用控制台时没有加载app注册表，最可能的原因是它是一个普通的python控制台而不是完全成熟的Django控制台。

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()
