I have never understood this construct method and have been wanting too f=
or a
while. Can someone tell me if this is a accurate undertanding?

construct takes a hash and turns it into an object. You execute a sql sta=
tement
to retrieve the data efficiently-- joins and all that -- so that several
queries are not executed to create the objects as happens typically when =
an
object has_a and has_many things. So something like the above example can=
 be
much faster than a simple retrieve_all.=20

Is that on target?

thanks.
