Define_method with dynamic method name

Ruby
1

Hi
I want to define new method with dynamic name eg:

def method_name
“abrakadabra”
end

define_method(method_name.to_sym){puts “done.”}

I cant do it this way, it causes: undefined local variable or method
`method_name’
Is there any other way to achieve this?

Are you using define method directly in the class body or from within an
instance method? In the first case (and also if you’re using it from a
class
method), then you need to define method_name as a class method, not as
an
instance method:

class C

def self.method_name
“abrakadabra”
end

define_method(method_name){puts “done.”}

end

C.new.abrakadabra

By the way, you don’t need to call to_sym, since define_method also
accepts a
string as argument.

I hope this helps
