Convert string to instance variable

Is there anyway to convert a string to an instance varible?

eg. Suppose I have @name defined. Is there any method that would return @name given the string "name" ?

Also, is there a similar method for local variables?

Thanks in advance, Thushan

Hi,

Thushan a écrit :

Yes there is. Just try instance_variable_get("@name") and you'll have the value of @name.

You should read the documentation of the Object class for more information :slight_smile: http://www.ruby-doc.org/core/classes/Object.html

Thanks Loïc. instance_variable_get and instance_variable_set worked for me.

What about local variables?
