Referring to previously overridden method without subclass

Ruby
1

I’m trying to debug a bit of code. I want to output all the parameters
passed to PGconn#exec each time it is called but still have the method
function as it should.

I tried this:

class PGconn
def exec(*args)
puts “exec: #{args}”
super *args
end
end

But super ends up calling Kernel#exec, how can I refer to the version of
exec before I added the puts enhancement?

I tried this:

class PGconn

  • alias_method :old_exec, :exec

def exec(*args)
puts “exec: #{args}”

  •   super *args

  •  old_exec(*args)
