from piccolo.columns import ForeignKey, JSON
from piccolo.table import Table


class User(Table):
    info = JSON()


class Book(Table):
    user = ForeignKey(references=User)
    info = JSON()

when use:user= Book.objects(Book.user).output(load_json=True)

.output(load_json=True) only deserialise Book.info to dict, and User.info is stil str

Is this a designed feature?
