Validation du document incorporé dans Mongoid

Question

J'ai un document Design.rb qui a un document attaché Attachment.rb qui effectue une validation. Si Attachment.rb échoue, le Design.rb doit également échouer, mais ce n'est pas le cas.

Des suggestions sur l'échec de ma classe de conception en cas d'échec du document incorporé?

Design.rb:

class Design 

    embeds_many :attachments, :as => :attachable 

    validates_associated :attachments 

    accepts_nested_attributes_for :attachments, :allow_destroy => true 

    field :description 
    field :title 
    field :tags, type: Array 
    field :featured, :type => Boolean, :default => false 
    field :full_member, :type => Boolean, :default => false 
    field :first_design, :type => Boolean, :default => false 
    field :option, :type => String 
    field :app_store_url, :type => String 
    field :design_in_progress, :type => Boolean 

    attr_accessible :design_in_progress, :tags, :description, :title, :featured, :project_number, :show, :option, :app_store_url, :temp_number, :option, :attachments_attributes 

    validates :description, :tags, :title, :presence => true 

end 

Attachment.rb

require 'carrierwave/mongoid' 

class Attachment 

    embedded_in :attachable, :polymorphic => true, :inverse_of => :attachments 

    field :image 
    field :width, :type => Integer 
    field :height, :type => Integer 
    field :option, :type => String 

    attr_accessible :image, :width, :height, :option, :normal, :url 

    mount_uploader :image, ImageUploader 

    validate :validate_minimum_image_size 

    def validate_minimum_image_size 
     self.option = self.attachable.option 

     case self.option 
     when "iphone" 
      width = 640 
      height = 960 
      type = "iPhone" 
     when "ipad" 
      width = 1536 
      height = 2048 
      type = "iPad" 
     when "icon" 
      width = 1024 
      height = 1024 
      type = "Icon" 
     when "wp" 
      width = 480 
      height = 800 
      type = "Windows Phone" 
     when "android" 
      width = 480 
      height = 800 
      type = "Android" 
     end 

     geometry = self.image.geometry 
     unless geometry.nil? 
      self.width = geometry[0] 
      self.height = geometry[1] 
     end 

     unless (self.width == width && self.height == height) 
      puts "INSIDE ERROR STATEMENT" 
      errors.add :base, "Naughty you... "+type+" designs should be "+width.to_s+"px times "+height.to_s+"px. We want to see your awesome design in retina :-)." 
     end 
    end 
end

Vous pourriez essayer d'ajouter

embeds_many :attachments, :as => :attachable, cascade_callbacks: true 

qui appellera les validations lorsque des changements sont effectués par le modèle de conception.
