Get constant value by using string?

ruby-talk
1

Hi,

My question is really simple :slight_smile:

class MyClass
  ANYTHING = "huh"
end

How can I print out huh from string?

MyClass::"anything".upcase

Is there any way to do that ?

:slight_smile:

Thanks for help...

Sure, for example:

   MyClass.module_eval("ANYTHING")
   MyClass.const_get("ANYTHING")

In Rails you also have:

   "MyClass::ANYTHING".constantize
