如何覆盖 CarrierWave 存储图像的位置？ def store_dir 似乎不起作用
我正在从 Attachment_fu 迁移到 Carrierwave，因为 Attachment_fu 在 Rails 3 中被破坏了，并且希望能够使用我已有的 Attachment_fu 图像文件，而不是 Carrierwave 制作新图像文件并将它们移动到其他地方。
我的图像按 ID 分区，因此如果用户 ID 为 61 并且他们上传名为 "foo.png" 的文件，那么他们的旧 Attachment_fu 图像将位于 “public/images/users/0000/0061/foo.png”
在我的用户模型中，我安装了 Carrierwave 图像上传器：
attr_accessible :user_avatar
mount_uploader :user_avatar, UserAvatarUploader
在我的 UserAvatarUploader 中，我有这个：
def store_dir
File.join Rails.root, "public/images/users", ("%08d" % model.id).scan(/\d{4}/).join("/")
end
所以当我设置了 :user_avatar，我应该得到 "public/images/users/0000/0061/foo.png"
但是当我尝试设置 :user_avatar< /code> 将 User 模型中的旧图像
user.user_avatar = "#{Rails.root}/public/images/users/0000/0061/foo.png"
返回为类似的内容"/uploads/tmp/20110916-1244-15398-7724/foo.png"
似乎 store_dir 没有被正确覆盖。我需要做什么才能使这项工作正常进行？
I'm moving from attachment_fu to carrierwave, since attachment_fu is broken with Rails 3, and would like to be able to use the attachment_fu image files that I already have, instead of carrierwave making new ones and moving them somewhere else.
My images are partitioned by id, so if the user id is 61 and they upload a file called "foo.png", then their old attachment_fu image would be at "public/images/users/0000/0061/foo.png"
In my users model, I mount the carrierwave image uploader with:
attr_accessible :user_avatar
mount_uploader :user_avatar, UserAvatarUploader
In my UserAvatarUploader, I have this:
def store_dir
File.join Rails.root, "public/images/users", ("%08d" % model.id).scan(/\d{4}/).join("/")
end
so when I set :user_avatar, I should get "public/images/users/0000/0061/foo.png"
but when I try to set the :user_avatar in the User model to the old image
user.user_avatar = "#{Rails.root}/public/images/users/0000/0061/foo.png"
it comes back as something like "/uploads/tmp/20110916-1244-15398-7724/foo.png"
It seems that store_dir is not being overwritten properly. What do I need to do to make this work right?

Carrierwave 默认基本位置是公共文件夹，
尝试使用以下命令更改它
Carrierwave default base location is the public folder
try to change it by using
