Question

Is there call_user_func_array() analog in Ruby? And how about create class from string, that contains class name. I found only with “eval”…

Answer 1

If you want to call a dynamic method name, use send:

user.send("method_#{i}")

This, if i = 1 will call the method_1 on user object.

Ruby uses the terminology “an object sends a message to another object” instead “calls a method/function”.
