Description

Hello,
Most filtering methods use the following syntax: method("field__subfield")

However, it seems that distinct uses the raw input.
MyObject.objects.distinct("field__subfield") does not return anything, whereas
MyObject.objects.distinct("field.subfield") does.

Shouldn't this be harmonized to use the same syntax as the other methods?

Thanks !
