Quartz::Verifiers::RuntimeChecker

A simple base class that can be used along with Verifiable#check_with

class MyModel
  include Verifiable
  check_with MyVerifier
end

class MyVerifier < RuntimeChecker
  def check(model)
    if some_complex_logic
      model.errors.add(:base, "This model is invalid")
    end
  end

  private def some_complex_logic
    # ...
  end
end

Any class that inherits from RuntimeChecker must implement a method called #check which accepts a model.

class MyModel
  include Verifiable
  check_with MyVerifier
end

class MyVerifier < RuntimeChecker
  def check(model)
    model # => The model instance being validated
  end
end

To cause a verification error, you must add to the model's errors directly from within the verifiers message.

class MyVerifier < RuntimeChecker
  def check(model)
    model.errors.add :attr1, "This is some custom error message"
    model.errors.add :attr2, "This is some complex validation"
    # etc...
  end
end

Note that the verifier is initialized only once for the whole application life cycle, and not on each verification run.
