validate blocks raise an exception about missing messages

[ThisIsMissEm]

Hi! I've the following code:

class MyValidator
  include Hanami::Validations::Form

  predicates Hanami::Validations::EmailPredicate
  validations do
    optional(:Properties).maybe(:hash?)
    validate(valid_properties: :Properties) do |rooms|
      properties.all? do |key, value|
        PropertyValidator.new(value).valid?
      end
    end
  end
end

Then else where I do: (there's a bit of additional abstraction, but it seems to not be important)

PropertyValidator.new(params).validate.success?

This then triggers the following error:

Dry::Validation::MissingMessageError (message for valid_properties was not found):

I've tried setting messages_path, and various other combinations of things that I've found between the Hanami::Validations and Dry::Validations READMEs and docs, but nothing seems to resolve this error.

What do I need to do in order to use the validate method in my validations block?

[ThisIsMissEm]

I'm needing to use the validate block because I've a schema where I have arbitrary keys in the hash, as per: dry-rb/dry-schema#37

@ThisIsMissEm I can't reproduce the problem, as the validations context doesn't respond to properties, so it crashes. Any hint on how to fix this script? 👇

# frozen_string_literal: true

require "bundler/setup"
require "hanami/validations"
require "hanami/validations/form"

module EmailPredicate
  include Hanami::Validations::Predicates

  self.messages_path = "./errors.yml"

  predicate(:email?) do |current|
    current.match(/@/)
  end
end

class PropertyValidator
  include Hanami::Validations::Form

  validations do
  end
end

class MyValidator
  include Hanami::Validations::Form

  predicates EmailPredicate

  validations do
    optional(:Properties).maybe(:hash?)

    validate(valid_properties: :Properties) do |rooms|
      rooms.all? do |_key, value|
        PropertyValidator.new(value).valid?
      end
    end
  end
end

params = {}

PropertyValidator.new(params).validate.success?
MyValidator.new(params).validate.success?
