When monkey patching a method, can you call the overridden method from the new implementation?

So I wish to simply add some conditional checks to a method by overriding it, but then I want the original method to be called. How does one do this in ruby?

ie.

method exists

def fakeMethod(cmd)
  puts "#{cmd}"
end

and I want to add

if (cmd) == "bla"
  puts "caught cmd"
else
  fakeMethod(cmd)
end

Any ideas?

Answer 1

alias :old_fake_method :fake_method
def fake_method(cmd)
  if (cmd) == "bla"
    puts "caught cmd"
  else
    old_fake_method(cmd)
  end
end
