问题描述

我正在使用 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，它给了我以下错误:

I'm using DRF and Pycharm 3.4.1 and Django 1.7. When I try to test my serializer class via Pycharm django console, it gives me the following error:

代码

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

然后导致以下错误回溯:

then cause the following error traceback:

但是当我使用终端(而不是pycharm django控制台)时，它可以正常工作！我知道 Pycharm 有问题，但我不知道如何解决！

but when I'm using my terminal(instead of pycharm django console), It works properly! I know there is a problem with Pycharm but I don't know how to fix it!

推荐答案

加载应用程序注册表是 django.setup 方法的一部分.如果开始使用控制台时未加载应用程序注册表，则最可能的原因是它是普通的python控制台，而不是功能齐全的Django控制台.

Loading the app registry is part of the django.setup method. If the app registry is not loaded when you start using the console, the most likely reason is that it is a plain python console instead of a fully blown Django console.

尝试以下代码.如果能够解决问题，则说明您确实在使用普通的python控制台.

Try the following code. If that solves it, you are indeed using a plain python console.

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