A listing has_one country A Country has_many listings A listing has_and_belongs_to_many ExportCountries An ExportCountry has_and_belongs_to_many Listings If I had two separate models I would probably do this: class Listing < ActiveRecord::Base belongs_to :country has_and_belongs

问题 I am implementing background email processing with Resque using the resque_mailer gem (https://github.com/zapnap/resque_mailer). I was able to get it to work for all my emails except the ones sent by Devise.
