Looks like the validator in the minutes model should be updated since we aren't 'importing' minutes anymore and it appears we have minutes in the database without dates. The validator below in models/minute.rb should be updated by dropping the unless (perhaps?):
class Minute < ActiveRecord::Base
belongs_to :item
belongs_to :meeting
belongs_to :minst
validates :date, presence: true, unless: "Rails.application.config.importing"
end
