module Quartz::Verifiable

Overview

Provides a runtime verification framework for your models.

Example:

class WeightModel
  include Quartz::Verifiable

  property weight : Float64 = 0.0 # in kg
  check :weight, numericality: {greater_than: 40, lesser_than: 160}
end

model = WeightModel.new
model.weight = 75.0
model.valid?   # => true
model.invalid? # => false

model.weight = 200.0
model.valid?          # => false
model.invalid?        # => true
model.errors.messages # => { :weight => ["must be lesser than 160"] }
