Righto -- unfortunately that's the best solution I've come up with to date. Here's the detailed version: # models.py def get_upload_path(instance, filename): return "%s/%s/%s" % (instance.__class__.__name__.lower(), instance.uuid, filename,) def get_uuid(): import uuid return

Write yourself a context processor and register it in your settings.TEMPLATE_CONTEXT_PROCESSORS. For example, registering myapp.context_processors.template_defaults: # myapp/context_processors.py def template_defaults(request): return { "BASE_TEMPLATE": "base/base.html",

Re: access value from request.GET.get in request.method == 'POST

First thing would be to ensure that when you submit the form back to itself, the querystring remains. It's all well and good to visit a form like this: /someapp/myform/?token=blah But if your HTML form tag is: Then you'll lose the "?token=blah" part when you submit. Other than that, nothing

Re: QuerySet.distinct and aggregates

I'd try both and compare the processing time. What is the nature of the Beta.name equivalent in your actual model? If it is a simple field (e.g. INT) I doubt the overhead would be too bad. What might be tripping me up is having your Gamma being linked to your Alpha through an intermediate model.

Re: fixtures for test fail to load

Your fixture probably contains objects whose model(s) contain foreign keys to other objects. class A(models.Model): pass class B(models.Model): a = models.ForeignKey(A) If your fixture only contains B objects, then importing will fail if the A objects they're keyed to don't exist. Test
