On the model
{{{
class Product(Model):
properties = JSONField()
}}}
when querying with {{{Product.objects.values('properties__color')}}}, the
resulting query is {{{SELECT ("product"."properties" -> 'color') FROM
"product"}}}
However, when using the equivalent F() expression {{{product =
Product.objects.values(color=F('properties__color'))}} the resulting query
is {{{SELECT "product"."properties" AS "color" FROM "product"}}}, which
ignores part of the field name
