Well, I think I have to answer to this. The problem is that Django caches its models in a singleton (singleton like structure) called AppCache. Basically, to reload Django models you need to first reload and re-import all the model modules stored in the AppCache. Then you need to wipe out the AppCache. Here’s the code for it:
import os
from django.db.models.loading import AppCache
cache = AppCache()
curdir = os.getcwd()
for app in cache.get_apps():
f = app.__file__
if f.startswith(curdir) and f.endswith('.pyc'):
os.remove(f)
__import__(app.__name__)
reload(app)
from django.utils.datastructures import SortedDict
cache.app_store = SortedDict()
cache.app_models = SortedDict()
cache.app_errors = {}
cache.handled = {}
cache.loaded = False
I’ve put all of this in a separate file called reloadmodels.py in the root directory of my Django site. Using IPython I can reload everything by running:
%run ~/mysite/reloadmodels.py
