[C.L.R],[RoR] How I convert string to method?

Hi,

suppose I have 2 strings:

s1 = “hello” s2 = “capitalize”

I want to do this:

m = s2.to_method s1.m => “Hello”

I’m working on a Rails project where I want to call arbitrary methods of a model class.

At run-time … I know how to get the names of the methods, but can’t figure out how to call the corresponding methods.

How I convert string to method?

I found the answer in the Pick Axe book:

s1.send(s2.to_sym)

"hello".send("capitalize".to_sym) => "Hello"

Or probably even better __send__ instead of send.
