Erreur lors de la soumission du processus de courrier personnalisé (à chaque fois que le plugin)

Question

J'essaie d'utiliser le plugin Whenever pour les rails pour effectuer un processus de modèle à certains moments.

Lorsque j'essaie d'utiliser le processus mail_out dans mon modèle utilisateur, j'obtiens l'erreur suivante. Quelqu'un peut-il me diriger dans la bonne direction de ce qui ne va pas?

/var/lib/gems/1.8/gems/rails-2.3.5/lib/commands/runner.rb:48: /var/lib/gems/1.8/gems/activerecord-2.3.5/lib/active_record/base.rb:1567:in `find_from_ids': Couldn't find User without an ID (ActiveRecord::RecordNotFound) 
    from /var/lib/gems/1.8/gems/activerecord-2.3.5/lib/active_record/base.rb:616:in `find' 
    from /home/tnederlof/Dropbox/Ruby/daily_trailer/app/models/user.rb:9:in `mail_out' 
    from (eval):1 
    from /usr/lib/ruby/1.8/rubygems/custom_require.rb:31:in `eval' 
    from /var/lib/gems/1.8/gems/rails-2.3.5/lib/commands/runner.rb:48 
    from /usr/lib/ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require' 
    from /usr/lib/ruby/1.8/rubygems/custom_require.rb:31:in `require' 
    from script/runner:3 

Mon schedule.rb est la suivante:

every 1.day, :at => '5:30 am' do 
    runner "User.mail_out" 
    end 

Mon modèle d'utilisateur est:

class User < ActiveRecord::Base 

    acts_as_authentic 

    def self.mail_out 

    weekday = Date.today.strftime('%A').downcase 

    @users = find(:conditions => "#{weekday}sub = t") 

    @users.each { |u| UserMailer.deliver_mail_out(u)} 


    end 

end 

Mon User_mailer est:

class UserMailer < ActionMailer::Base 
    def mail_out(users) 
    @recipients = { } 
    users.each do |user| 
     @recipients[user.email] = { :name => user.name } 
    end 


    from  "no-reply@dailytrailer.net" 
    subject  "Check out the trailer of the day!" 
    body  :user => user 
    end 

end 

Migration:

create_table "users", :force => true do |t| 
    t.string "email" 
    t.date  "birthday" 
    t.string "gender" 
    t.string "zipcode" 
    t.datetime "created_at" 
    t.datetime "updated_at" 
    t.string "crypted_password" 
    t.string "password_salt" 
    t.string "persistence_token" 
    t.string "mondaysub",   :default => "f", :null => false 
    t.string "tuesdaysub",  :default => "f", :null => false 
    t.string "wednesdaysub",  :default => "f", :null => false 
    t.string "thursdaysub",  :default => "f", :null => false 
    t.string "fridaysub",   :default => "f", :null => false 
    t.string "saturdaysub",  :default => "f", :null => false 
    t.string "sundaysub",   :default => "f", :null => false 
    end 

Answer 1

Modifier ceci:

find(:conditions => "#{weekday}sub = t") 

à

find(:all, :conditions => "#{weekday}sub = t")
