Class Method Details

.setup_after ⇒ Object

Wrapping optional associations requires that we include the module after the class is first evaluated, so that it can define its associations for later reflection.

def self.setup_after
  Zeitwerk::Loader.eager_load_all
  setupable = defined?(ApplicationRecord) ? ApplicationRecord : ActiveRecord::Base
  setupable.descendants.each do |model|
    next unless begin
      model.table_exists?
    rescue StandardError
      false
    end

    model.include Errgonomic::Rails::ActiveRecordOptional
  end
end

.setup_before ⇒ Object

We provide helper class methods, like ‘delegate_optional`, which need to be included into ActiveRecord::Base before any models are evaluated.
