define method for instance of class
- by aharon
Let there be class Example defined as:
class Example
def initialize(test='hey')
self.class.send(:define_method, :say_hello, lambda { test })
end
end
On calling Example.new; Example.new I get a warning: method redefined; discarding old say_hello. This, I conclude, must be because it defines a method in the actual class (which makes sense, from the syntax). And that, of course, would prove disastrous should there be multiple instances of Example with different values in their methods.
Is there a way to create methods just for the instance of a class from inside that instance?
Thanks so much.
