在我的Linux开发环境设置回形针与S3是易如反掌 - 一切正常开箱。但是,我无法得到它的工作在Heroku上。
Setting up paperclip with S3 in my linux dev environment was a snap -- everything works out of the box. However, I can't get it to work on Heroku.
当我尝试做一个上传,日志显示:
When I try to do an upload, the log shows:
Processing ItemsController#create (for 72.177.97.9 at 2010-08-26 16:35:14) [POST]
Parameters: {"commit"=>"Create", "authenticity_token"=>"0Hy3qvQBHE1gvFVaq32HMy2ZIopelV0BHbrSeHkO1Qw=", "item"=>{"photo"=>#<File:/home/slugs/270862_4aa601b_4b6f/mnt/tmp/RackMultipart20100826-6286-1256pvc-0>, "price"=>"342", "name"=>"a new item", "description"=>"a new item", "sold"=>"0"}}
Paperclip::PaperclipError (Item model missing required attr_accessor for 'photo_file_name'):
我发现,引用此错误的一个博客网站的帖子,并说把它添加到我的模型:
I found one blog post that referenced this error, and it said to add this to my model:
attr_accessor :photo_file_name
attr_accessor :photo_content_type
attr_accessor :photo_file_size
attr_accessor :photo_updated_at
这确实使模型缺少photo_file_name错误消失要求attr_accessor,但它仍然无法正常工作。请参阅my另一个问题,了解详细信息。正如我已经想通了,与attr_accessor线添加到我的模型上传我开发的系统故障,甚至,我怀疑是不是正确的答案。
That does indeed make the model missing required attr_accessor for 'photo_file_name' error go away, but it still doesn't work. See my other question for details. As I have figured out that with the attr_accessor lines added to my model the uploads fail even on my dev system, I suspect that is not the right answer.
推荐答案
发现问题:需要对数据库进行更新
Found the problem: needed to update the database.
Heroku的运行rake:分贝:迁移
heroku run rake:db:migrate
Heroku的重启
我已经做了我认为将完成同样的事情早已:
I had done what I thought would have accomplished the same thing already:
Heroku的耙分贝:模式:负载
heroku rake db:schema:load
但也许不工作或出事了这一进程。
but perhaps that doesn't work or something went wrong in the process.
