Missing translations with default values as option

[nitxal]

Hi there, I am using Missing Module, everything works well without default option, like this

I18n.t('hi')

however I need to save as well in translations table, missing translations although exists default values as option, for example in the following line codes, records are not created

I18n.t('hello', default: 'Hello')
I18n.t('hello', locale: 'es', default: 'Hello')
I18n.t('hello', locale: 'ja', default: 'Hello')

How do I achieve this? This is my configuration:

I18n.load_path += Dir[Rails.root.join('config', 'locales', '*.{rb,yml}')]

I18n.available_locales = [:en, :es, :ko, :ja]

I18n.default_locale = :en

I18n::Backend::ActiveRecord.configure do |config|
  config.cache_translations = Rails.env.production?
end

if Translation.table_exists?
  I18n.backend = I18n::Backend::ActiveRecord.new

  I18n::Backend::ActiveRecord.send(:include, I18n::Backend::Memoize)
  I18n::Backend::ActiveRecord.send(:include, I18n::Backend::Flatten)
  I18n::Backend::ActiveRecord.send(:include, I18n::Backend::Cache)

  I18n::Backend::Simple.send(:include, I18n::Backend::Memoize)
  I18n::Backend::Simple.send(:include, I18n::Backend::Pluralization)

  I18n::Backend::Chain.send(:include, I18n::Backend::ActiveRecord::Missing)
  I18n.backend = I18n::Backend::Chain.new(I18n.backend, I18n::Backend::Simple.new)
end

Unfortunately, the current implementation of the Missing module doesn't allow saving default values.
So I am afraid there is no way to achieve this without changing the implementation.

The idea of the Missing module is to create blank records for missing translations so translators can review them, so I am not entirely sure that saving default values by default would be right.
But this can be an optional behaviour configured with the I18n::Backend::ActiveRecord.configure

Feel free to send a pull request, otherwise, I will try to look at it when I have some time
