Откат транзакции с валидаций сворачивается в ActiveRecord

Question

Модель:

class Project < ActiveRecord::Base 

    attr_accessible :description, :due_date, :expiration_date, :extra_reward, :hours_needed, :location, :mission, :participants_id, :project_picture, :required_skill, :title, :gnikles, :topic, :community_id 
    belongs_to :user 
    belongs_to :community 
    has_many :skills 

    validates :title, :presence => true, :length => { :maximum => 100 } 
    validates :hours_needed, :presence => true, :inclusion => { :in => 0..20 }, :numericality => true 
    validates :description, :presence => true 
    validates :required_skill, :presence => true 
    validates :due_date, :presence => true 
    #validates :expiration_date, :presence => true 

end 

Попытка создать тестовый проект, я получаю это:

1.9.3-p194 :025 > Project.create(:title =>"Testings", :description =>"fdsafdsfsa", :topic => 33, :community_id => 3, :expiration_date => "09/09/2013", :due_date =>"09/28/2013", :hours_needed => 1, :required_skill =>1) 
    (0.1ms) begin transaction 
    (0.0ms) rollback transaction 
=> #<Project id: nil, title: "Testings", description: "fdsafdsfsa", required_skill: 1, extra_reward: nil, expiration_date: "2013-09-09 00:00:00", due_date: nil, hours_needed: 1, views: nil, user_id: nil, topic: 33, gnikels: 0, completed: 0, created_at: nil, updated_at: nil, community_id: 3> 

Почему бы due_date не получить прошли вместе, но expiration_date показывает без проблем?

Answer 1

Поскольку "09/28/2013" не является допустимой строка даты:

'09/28/2013'.to_date # => ArgumentError: invalid date 
'28/09/2013'.to_date # => Sat, 28 Sep 2013 
'2013-09-28'.to_date # => Sat, 28 Sep 2013
