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’).
