This project exposes a bug when a default manager returns a queryset that has a deferred field.

DjangoBug

When the default manager returns a queryset with a deferred field, the dumpdata command fails to produce importable data.

Steps to reproduce

1. Setup the environment

   $ git clone https://github.com/cecedille1/DjangoBug.git . $ virtualenv . --python python3 $ source bin/activate $ pip install -r requirements.txt $ bug migrate $ bug loaddata initial

2. Reproduce the bug

   $ bug dumpdata [{"model": "my_bug.mymodel_deferred_an_expensive_value", "fields": {"value": "abc", "an_expensive_value": "dGhpcw=="}, "pk": 1}]>>

The name of the model is mymodel_deferred_an_expensive_value and Django wont be able to load it later.
