What is the "best practice" for determining whether or not
a model object corresponds to a database record that has been
deleted?
Say I have a collection of Book objects, some of which have
been removed from the database with:
@book = Book.find(blah)
@book.destroy
...
@books << @book # don't know at this point whether @book has been destroyed
Now when I iterate through @books, I'd like to detect the
ones that have been destroyed.
It appears that the destroyed ones will be "frozen" (@book.frozen? == true),
but assuming that frozen == destroyed seems somehow indirect
and side-effecty. Is there a more straighforward way (short of re-querying
the database) that I'm missing?
Thanks...
