Hi all,

I'm trying to DRY my latest Rails project and have run into a problem for
which the answer appears to lie in my personal sea of ignorance.

I want to write a helper that will let me set the fields I want to display
before I start looping.

Basically I wish to pass the class name and an array of fields to be ignored
to the helper and have it give me an array of the fields I want.

The problem is this, I have no idea how to get Ruby to treat the string I
pass as a classname.  I did some searching and didn't find anything that
looked like it would solve my problem.

I'd rather not have to create a new instance if I don't have to.

Thanks,
Glen
