Dr. Dobbs Article

[Andy Stone]

I just received the latest DDJ which contained an article titled
"Databases & Dynamic Ruby Classes." I haven't had the chance to read
it (too busy), but it was good to see Ruby getting more exposure.
(Especially in a magazine such as DDJ)

Just an fyi for the group.

Well I just read it. Pretty interesting. It was about using
method_missing to do DB updates (ie something.property =
something_else, update the DB at the key propety, etc.) and some
interesting stuff about storing ruby code in the database as opposed
to in the source. Pretty neat.

To me, as a ruby slightly-post-newby, method_missing is a unique and
powerfull feature that makes ruby feel like a truely 'real' OO
language. That is message passing rather than method calls with
implicit this objects.

I love it! If only you could catch java.lang.NoSuchMethodError in the
callee rather than the caller...

Since java is a strongly typed language that won't happen :/ The method
must exist on the receiver. You're probably already aware of it, but you
can do something similar by using dynamic proxies in java. Check out
java.lang.reflect.Proxy and java.lang.reflect.InvocationHandler.
