Assuming your variable contains a string, try this:

  method_name = "feed"
  pet.send(method_name)

-mats

Subject: Newbie question: variable method call

Is there a way to use the value of a variable to call a method of that
name?

For example, rather than use the following code to determine which
method of the 'pet' object to call:

if action == "feed"
     pet.feed
elsif action == "walk"
     pet.walk
elsif action == "pat"
    pet.pat
#etc...
end


I'd rather just do something like this:

pet.action


The problem is, Ruby thinks I am trying to call a method named 'action',
instead of evaluating the variable and using its value (e.g. 'feed').
