我有一个非常简单的 sinatra 应用程序,它使用 datamapper 和carrierwave。
我已将上传器减少到最低限度:
class PhotoUploader < CarrierWave::Uploader::Base
include CarrierWave::MiniMagick
storage :file
end
并有一个使用它的简单模型:
class Photo
include DataMapper::Resource
property :id, Serial
property :caption, String
property :position, Integer
property :created_at, DateTime
property :updated_at, DateTime
mount_uploader :source, PhotoUploader
belongs_to :album
end
碰巧当我使用它时:
post '/admin/album/:id/photo/create' do
album = Album.get(params[:id])
photo = Photo.create(params[:photo])
album.photos << photo
album.save!
redirect '/admin/album'
end
photo
正在数据库上正常创建,并且文件正在正常上传到缓存目录,但未移动到最终存储目标。
我已经进入了载波代码,并且可以验证cache!
正在调用该方法而不是该store!
方法。
我尝试使用与对象没有任何关联的上传器:
get '/lorem' do
f = File.open('test.png')
u = PhotoUploader.new
u.store!(f)
"ok"
end
在这种情况下,一切都按预期工作。

我相信我已经找到了问题的根源。在运行调试器时,我得到了这个:
gems/dm-core-1.2.0/lib/dm-core/query.rb:1014
conditions.each do |condition|
(rdb:1)
gems/carrierwave-0.6.2/lib/carrierwave/sanitized_file.rb:290
def sanitize(name)
(rdb:4)
gems/carrierwave-0.6.2/lib/carrierwave/sanitized_file.rb:299
def split_extension(filename)
(rdb:4)
gems/carrierwave-0.6.2/lib/carrierwave/sanitized_file.rb:29
self.file = file
(rdb:4)
gems/carrierwave-0.6.2/lib/carrierwave/sanitized_file.rb:269
if file.is_a?(Hash)
(rdb:4)
gems/carrierwave-0.6.2/lib/carrierwave/sanitized_file.rb:274
@file = file
(rdb:4) pp file
"/Users/jvalente/Projects/dummy/public/uploads/{:filename=>\"Screen Shot 2013-01-24 at 4.57.15 PM.png\", :type=>\"image/png\", :name=>\"photo[source]\", :tempfile=>#<File:/var/folders/jp/wm1gxk8558d36rh9vzkmx4jw0000gn/T/RackMultipart20130128-27245-105ybbf>, :head=>\"Content-Disposition: form-data; name=\\\"photo[source]\\\"; filename=\\\"Screen Shot 2013-01-24 at 4.57.15 PM.png\\\"\\r\\nContent-Type: image/png\\r\\n\"}"
这显然是错误的,因为它将不符合file.is_a?(Hash)
条件并进入:
@file = file
@original_filename = nil
@content_type = nil
不过,我不明白为什么会发生这种情况。
