Access variables programmatically by name in Ruby

Question

I\'m not entirely sure if this is possible in Ruby, but hopefully there\'s an easy way to do this. I want to declare a variable and later find out the name of the variable.

Answer 1

I do not know of any way to get a local variable name. But, you can use the instance_variables method, this will return an array of all the instance variable names in the object.

Simple call:

object.instance_variables

or

self.instance_variables

to get an array of all instance variable names.
