Array Inquirer ↑

Wrapping an array in an ArrayInquirer gives a friendlier way to check its string-like contents:

variants = ActiveSupport::ArrayInquirer.new([:phone, :tablet])

variants.phone?    # => true
variants.tablet?   # => true
variants.desktop?  # => false
Methods
A

Instance Public methods

any?(*candidates)

Passes each element of candidates collection to ArrayInquirer collection. The method returns true if any element from the ArrayInquirer collection is equal to the stringified or symbolized form of any element in the candidates collection.

If candidates collection is not given, method returns true.

variants = ActiveSupport::ArrayInquirer.new([:phone, :tablet])

variants.any?                      # => true
variants.any?(:phone, :tablet)     # => true
variants.any?('phone', 'desktop')  # => true
variants.any?(:desktop, :watch)    # => false
