Rails - Jul 2006 - Calling Method

Is there a way to call a method if I only have a string that contains 
the method name.

For example:

@methods = [''method1'', ''method2'',
''method3'']
@step = 1

# I want to call method2 which has a definition in this class

Not sure what you mean by "call" but if, for example, you were trying
to
redirect_to I think...

redirect_to :action => eval(@methods[1])

might do what you want.

Thanks for the pointer.

self.send(@methods[@step]) worked.
