How to run variable method names?

Ruby
1

Lets say object has a method called id.

How do I do the the following?

method_name = “id”
object.method_name

I know the above doesnt work, but I want method_name to be replaced
by its value so it would run id.

Thanks for the help.

Thank You,

In this case Ruby is interpreting method_name as the method to call.
Check out Object#send

object.send(method_name.to_sym)

No need to call to_sym – send will accept a string.

You would use __send__' in the eventsend’ is overriden.

‘neb’.send(:reverse) #=> ‘ben’
