Constantize

March 30, 2011

Consider a variable like

var = “Klass” how you do you something equivalent to

Klass.method_name?

Answer:

var.constantize.method_name
Example:

ruby-1.9.2-p136 :086 > "Resource".constantize.count
 => 5
ruby-1.9.2-p136 :087 > "resource".classify.constantize.count
 => 5
