Hey All,

I've just written a custom model field for storing anything which is
pickle-able (generally this will be used for storing dictionaries). It
all works great, apart from when I want to perform a query on objects
using the field as an argument. When doing something like:

SomeModel.objects.filter(my_field={'foo': 'bar', 'bar': 'baz'})

However, it seems to reduce my dictionary to an iterable containing
just the dictionary keys (so, in this case ['foo', 'bar']). I presume
Django is doing this by iterating over the dictionary, but obviously
this doesn't work for my field. Is there any way to stop Django from
doing this, away from overriding query methods in the manager to
convert the dictionary to something non-iterable?

Any help much appreciated!

Thanks,
O
