35690	Calling queryset.in_bulk() after queryset.values() or queryset.values_list() results in unhelpful error	john-parton	john-parton	"Calling
{{{
MyModel.objects.values().in_bulk()

Results in a rather annoying error message that doesn't help the user.


{{{
Traceback (most recent call last):

}}}

This is because the `in_bulk` method assumes that the queryset has the default `_iterable_class` (`ModelIterable`) and is attempting to access a property on an object, but the `_iterable_class` returns dictionaries.

The correct behavior should be either to:

1. Raise a more helpful error if the user attempts to call `in_bulk()` where the _iterable_class isn't the standard ModelIterable; or
2. Define behavior for when `in_bulk()` is called in that case. (I think that might be rather challenging, so Behavior 1 is probably the better option.)
