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.
