Using errors.add(:key, 'some text') doesn't translate :key in rails 5

[karlingen]

Attribute names are no longer translated. I'm not sure where the problem is, wether it is with reform-rails, i18n and/or rails. Maybe I'm calling the error messages in a wrong way.

Example:

module Documents::Contract
  class Create < Reform::Form

    property :name
    validate :file_has_valid_format?

    private

    def file_has_valid_format?
      errors.add(:name, I18n.t('validation.messages.error.file_type_upload_invalid'))
    end
  end
end

In rails 4 :name was translated to whatever I had defined in activerecord.en.yml:

en:
  activerecord:
    attributes:
      document:
        name: "The X File"
        description: "Descriptionzz"

I'm getting the error message like this:

@form.errors.full_messages.join(". ")

Gemfile.lock:

trailblazer-rails (1.0.2)
      reform-rails (>= 0.1.4, < 0.2.0)
      trailblazer (>= 2.0.0, < 2.1.0)
      trailblazer-loader (>= 0.1.0)

Hmm.. Perhaps this PR fixes it: #35
