Numericality :within validator

[kristianmandrup]

I am trying to simplify the numericality validator a little by allowing something like

validates :price_range, :numericality => {:within => 10..20}

instead of

validates :price_range, :numericality => {:greater_than_or_equal_to => 10, :less_than_or_equal_to => 20}

It looks to me like the :within option currently only works for the length of an attribute?

I tried to add a test case and an update to the translation file, but I don't know enough about the Rails internals for validations and how it works behind the scenes.

You don't need to add a new translation option. You just need to break :within into two options. For example: :within => 10..20 should become :less_than_or_equal_to => 20 and :greater_than_or_equal_to => 10. I believe this is how the length validator behaves.
