Overview

The rules for parsing validations are such:

  • Validations are method calls (starting with the string ‘validates_`)

  • followed by field names as regular arguments (as symbols)

  • any options are included in an options hash, eg. is: String

  • and native blocks are reserved for children-validations

For example:

validates_subhash :iap1, :iap2, when: -> { type == :iap } do
  validates_type_of :id,   is: String
  validates_type_of :tier, is: Numeric
end
