Have you thought about using more meaningful key values? E.g.,
TYPE = (('FOO', 'foo display'), ('BAR', 'bar display'))
If you're stuck with magic numbers as keys you could always flip the
tuples for key lookup by value:
TYPE_KEYS = dict([(v,k) for k,v in TYPE])
Foo.objects.filter(type=Foo.TYPE_KEYS['foo display'])
You could also hang code-friendly values off your Foo object so you
could do:
class Foo(Model):
foo_display = TYPE_KEYS['foo display']
Foo.objects.filter(type=Foo.foo_display)
I'd push for the more readable keys.
