Ruby: toggle a boolean inline?

Question

How can I get the opposite of a boolean in Ruby (I know that it is converted to 0/1) using a method inline?

say I have the given instance:

class Vote

  def return_opposite
    self.value
  end

end

Which obviously doesn't do anything, but I can't seem to find a method that is simple and short something like opposite() or the like. Does something like this exist and I'm just not looking at the right place in the docs? If one doesn't exist is there a really short ternary that would toggle it from 1 => 0 or 0 => 1?

Answer 1

I like to use this

@object.boolean = [email protected]
