Subject: Getting Object From String?

Howdy,

I have a class called 'NewsItem'.

In one of my Rails classes, I have a place to pass in a string (from a HTTP
parameter). That string's value is 'NewsItem', the class name.

How can I convert that to use as the class?

I.e.

@model = params[:modelname]
@items = @model.find(:all)

This doesn't work. I was hoping it would work the same way as:
@items = NewsItem.find(:all)

How can I pull this off?

Thanks!
