possible to extend (not overwrite) a plugin method?

Hi,

Is it possible to extend a plugin method?

In a class that uses a plugin which already defines, say, a before_create method, is it possible to extend this before_create so the code in the plugin's method is also invoked ? Something in effect like calling super in an inherited class' overwriting method. I suppose this is either easy with some less-known syntax, which I haven't found, or this is impossible currently (I know it's not a biggie to copy over the code from the plugin method, but...)

Thanks!

I agree that subclasses are better when possible. That said, if you do have to alias and chain, use alias_method_chain to keep it cleaner:

Thanks Alex! Unfortunately the plugin offers mixin methods, such as one of those acts_as_... plugins.... So, there is no class I can subclass from.

What a wicked double alias.... This is oddly cool in a way....

Thanks Rob! Pretty cool.

So glad to know advanced RoR'ers out there like you and Alex.
