Refactoring boolean conditions

Question

How can I simplify this method?

def check(foo, bar = nil)
  if bar
    @object.foo > foo && @object.bar > bar
  else
    @object.foo > foo
  end
end

Answer 1

def check(foo, bar = nil)
  @object.foo > foo && (bar.nil? || @object.bar > bar)
end

Another option if such checks are common place and longer.

def checkif(m,x)
  return x.nil? || @object.send(m) > x
end

def check(foo, bar = nil)
  [[:foo,foo], [:bar,bar]].all?{|v| checkif(v[0],v[1]) }
end
