我正在使用DRFandPycharm 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，它给我以下错误：
代码
from items_app.serializers import ItemSerializer
s = ItemSerializer()
print(repr(s))
然后导致以下错误回溯：

但是当我使用终端（而不是pycharm django控制台）时，它可以正常工作！我知道这有问题，Pycharm但我不知道如何解决！
加载应用程序注册表是该django.setup方法的一部分。如果在开始使用控制台时未加载应用程序注册表，则最有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。
试试下面的代码。如果这样可以解决，那么您确实在使用普通的python控制台。
>>> import django
>>> django.setup()
