我不確定嵌入類的控制器應該發生什麼。傳遞的參數會顯示所有嵌入的類屬性,包括圖像屬性,但只有非圖像參數纔會保存在數據庫中。這告訴我,這個問題是不是與ORM的(Mongoid在這種情況下)的選擇,而是與我使用的載波方式:Rails:與載波的嵌套形式
Parameters: {"article"=>{"name"=>"New article", "comments_attributes"=>{"0"=>{"remote_image_url"=>"", "name"=>"Comment 1", "content"=>"comment content....", "image"=>#<ActionDispatch::Http::UploadedFile:0x10339d880 @headers="Content-Disposition: form-data; name=\"article[comments_attributes][0][image]\"; filename=\"dh.png\"\r\nContent-Type: image/png\r\n", @original_filename="dh.png", @tempfile=#<File:/var/folders/A1/A1SUPUTUFA8BYB5j+RD2L++++TI/-Tmp-/RackMultipart20120228-21178-1vckii1-0>, @content_type="image/png">}}, "content"=>"article content"}, "commit"=>"Create Article", "authenticity_token"=>"i14YuJs4EVKr5PSEw9IwKXcTbQfOP4mjbR95C75J2mc=", "utf8"=>"\342\234\223"}
MONGODB (89ms) freedb['system.namespaces'].find({})
MONGODB (0ms) freedb['articles'].insert([{"name"=>"New article", "comments"=>[{"name"=>"Comment 1", "_id"=>BSON::ObjectId('4f4daf6a58001652ba000012'), "content"=>"comment content...."}], "_id"=>BSON::ObjectId('4f4daf6958001652ba000011'), "content"=>"article content"}])
父模型:
class Article
include Mongoid::Document
field :name, :type => String
field :content, :type => String
embeds_many :comments
accepts_nested_attributes_for :comments
end
子模型:
require 'carrierwave/mongoid'
class Comment
include Mongoid::Document
field :name, :type => String
field :content, :type => String
field :image, :required => true
field :remote_image_url
embedded_in :article, :inverse_of => :comments
mount_uploader :image, ImageUploader
end
父控制器:
def new
@article = Article.new
@article.comments.build
end
def create
@article = Article.new(params[:article])
end

我面臨同樣的問題。 Dave ans爲我工作。 http://stackoverflow.com/questions/6447278/uploading-multiple-files-at-once-to-rails-app-with-carrierwave-html5 – Tim 2012-02-29 10:10:13
