validates_numericality_of just got a shot of mojo this weekend in the form of some highly useful options.

Prior to this recent change, your numerical validation options were limited to only_integer and allow_nil. Any desires to do anything slightly more complex meant dropping down into your own validation routine. Now, some of the more common validations one might want on a number parameter have been option-ized, including:
  • greater_than
  • greater_than_or_equal_to
  • equal_to
  • less_than
  • less_than_or_equal_to
  • odd
  • even

Which allows us to do things such as:

1
2
3
4

validates_numericality_of :salary, :greater_than_or_equal_to => 40000
validates_numericality_of :ten, :equal_to => 10
validates_numericality_of :bonus, :less_than => 5000
validates_numericality_of :prime, :odd => true

So put away that crusty custom validate and plug into these fresh validation options. Guaranteed to make your life easier.
