Description

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
