我使用了 Cloudinary gem,到目前为止,它作为Photo
Mongoid 中的嵌入式模型运行良好:
class PhotoUploader < CarrierWave::Uploader::Base
include Cloudinary::CarrierWave
def public_id
return model.id
end
end
class Photo
include Mongoid::Document
include Mongoid::Timestamps
embedded_in :place#, :inverse_of => :photos, :autosave => true
mount_uploader :image, PhotoUploader
#...
end
但是,升级到 Mongoid 3 后,获取图像 URL 不再有效。考虑这个照片模型:
1.9.3p194 :019 > p
=> #<Photo _id: 507bc3c82a450b14bd00e00a, _type: nil, created_at: 2012-10-15 08:05:28 UTC, updated_at: 2012-10-15 08:05:28 UTC, image_filename: nil, caption: nil, original_url: "http://www.reactionny.com//images/assets/101755_316529.JPG", image: "v1350288333/507bc3c82a450b14bd00e00a.jpg">
1.9.3p194 :020 > p.image
=> /assets/fallback/default.png
1.9.3p194 :021 > p.image_url
=> "/assets/fallback/default.png"
1.9.3p194 :022 > p['image']
=> "v1350288333/507bc3c82a450b14bd00e00a.jpg"
为什么它不再以 形式返回完全限定的 Cloudinary URL http://res.cloudinary.com/XXXXXX/image/upload/v1350288842/507bc5ca2a450b14bd00e896.jpg
