Calling Method

Rails
1

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

Thanks for the pointer.

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

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.
