# Card

17
# Note that we store a card_type_id, as opposed to a card_type, because
18
# otherwise we can't use pickled databases, as the card_types themselves are
19
# not stored in the database. It is also closer the SQL implementation.
20
#
21
# 'fact_view' indicate different cards generated from the same fact data,
22
# like reverse cards. TODO: do we need a mapping from this integer to a
23
# description?
24
#
25
# For UI simplicity reasons, the user is not allowed to deleted one of a set
26
# of related cards, only to deactivate them. This is a second, orthogonal
27
# selection mechanism to see if cards are active, together with not being
28
# in a deactivated category.
17
# Essentially the coming together of a Fact and a FactView.
