Get constant value by using string?

Ruby
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…

MyClass.const_get(“anything”.upcase)

Sure, for example:

MyClass.module_eval(“ANYTHING”)
MyClass.const_get(“ANYTHING”)

In Rails you also have:

“MyClass::ANYTHING”.constantize
