#
# The most important aspect of the new Property API is that
# property inheritance should not be used to instruct
# adapters how to persist data. It means, for example, that 
# you should not use Integer as the base class for your custom
# property just because it is persisted as an integer. Right now
# Enum inherits from Integer because it is stored as an integer.
# It is a mistake, because a value of Enum property can be either
# a string or a symbol, not integer. The fact that it is persisted

# Computes STI models who are grandchildren or more.
#
# In a STI the root class and its subclasses work normally, but if there are
# grandchildren we need to preload them. Reason is, given A < B < C, if you
# for example compute B.count without loading A, only B records are taken into
# account in the query (where a clause about the type column intervenes). This
# is not a bug, Active Record is simply not aware of A. Once it is, the clause
# becomes an OR with all relevant types.
#
# I used this script to compute them.
