Overview

This class acts as a registry for reminders. Each reminder needs a name, and a generator class, that will be used for generating the actual sendable reminders. Reminder times could be used to define intervals between reminders, so that user is not reminded too often. In addition, you can register form and command classes for additional features, such as order reminders can be sent manually from the admin panel. Notice that if you implement admin panel functionality, you should add 118n messages too.

In order to register a reminder, you can follow this example:

Decidim.reminders_registry.register(:orders) do |reminder_registry|
  reminder_registry.generator_class_name = "Decidim::Budgets::OrderReminderGenerator"
  reminder_registry.form_class_name = "Decidim::Budgets::Admin::OrderReminderForm"
  reminder_registry.command_class_name = "Decidim::Budgets::Admin::CreateOrderReminders"

  reminder_registry.settings do |settings|
    settings.attribute :reminder_times, type: :array, default: [2.hours, 1.week, 2.weeks]
  end

  reminder_registry.messages do |msg|
    msg.set(:title) { |count: 0| I18n.t("decidim.budgets.admin.reminders.orders.title", count: count) }
    msg.set(:description) { I18n.t("decidim.budgets.admin.reminders.orders.description") }
  end
end

Reminders need to be registered in the ‘engine.rb` file of each module.
