Rails4 Mongoid Paperclip不上传文件，但其他一切

我有一个使用Mongoid和Mongoid-Paperclip的Rails4项目。 我有ImageMagick刚刚设置，命令似乎工作。 创建了保存图像的模型，所有图像字段都被填充。 唯一不起作用的是将文件复制到public / system / ...文件夹（在我的mac上的开发模式下）。

以下是代码和输出：

目录图像（由部件嵌入）

class CatalogImage
  include Mongoid::Document
  include Mongoid::Paperclip

  field :caption

  embedded_in :part, inverse_of: :catalog_images
  has_mongoid_attached_file :image,
      :path => ":rails_root/public/system/:attachment/:id/:style/:filename",
      :url => "/system/:attachment/:id/:style/:filename",
      :styles => { :small => "200x200>", :medium => "500x500>" }
  validates_attachment_content_type :image, :content_type => %w(image/jpeg image/jpg image/png)
end

部分（嵌入许多目录图像）

class Part
  include Mongoid::Document
  field :name
  field :description
  field :price
  field :clickout

  embeds_many :catalog_images

  accepts_nested_attributes_for :catalog_images

end

的Gemfile 

...
gem 'mongoid', '4.0.0.beta1', github: 'mongoid/mongoid'
gem 'bson_ext'

gem "mongoid-paperclip", :require => "mongoid_paperclip", :git => "git://github.com/meskyanichi/mongoid-paperclip.git", :branch => "develop"
...

先谢谢， Steff

答案 0 :(得分：2)

保存父级时，不会保存嵌入文档中的文件。这意味着除非您明确说明，否则无法保留文件。在你的情况下：

embeds_many :catalog_images, cascade_callbacks: true

来自https://github.com/meskyanichi/mongoid-paperclip

  

关于嵌入式文档的注意事项：如果您计划保存或更新父文档，则必须将cascade_callbacks：true添加到embeds_XXX语句中。否则，您的数据将被更新，但回形针功能将无法运行以复制/更新您的文件。

答案 1 :(得分：0)

感谢veritas1，我能够修复它。 我不得不在“embeds_many”行添加“cascade_callbacks = true”。

class Part
  include Mongoid::Document
  field :name
  field :description
  field :price
  field :clickout

  embeds_many :catalog_images, cascade_callbacks: true

  accepts_nested_attributes_for :catalog_images

end
