How to check if a number is included in a range (in one statement)?
(1..10).include?(number)
is the trick.
Btw: If you want to validate a number using ActiveModel::Validations
, you can even do:
validates_inclusion_of :number, :in => 1..10
read here about validates_inclusion_of
or the Rails 3+ way:
validates :number, :inclusion => 1..10
(1..10).include? n
(1..10).cover? n
n.between? 1, 10
validates :n, numericality: {only_integer: true, greater_than_or_equal_to: 1, less_than_or_equal_to: 10}
validates :n, inclusion: 1..10
If it's not part of a validation process you can use #between?
:
2.between?(1, 4)=> true
