S3存儲失敗，霧0.7.2 + carrierwave主分支

當試圖存儲文件，我得到以下幾點：S3存儲失敗，霧0.7.2 + carrierwave主分支

我試着手動調試，我和懷疑問題是否關係中事實上@content_type被設置爲零，儘管我還沒有能夠比這更進一步推論。

這是一個S3（或霧，我沒有任何其他供應商）具體問題，我的項目使用時工作正常：文件存儲。思考？

這個問題只是咬我一口。

S3_CONFIG = YAML.load_file(Rails.root.join('config', 'amazon_s3.yml'))[Rails.env] 

CarrierWave.configure do |config| 
    config.storage    = :s3 
    config.s3_access_policy  = :public_read 
    config.s3_access_key_id  = S3_CONFIG['access_key_id'] 
    config.s3_secret_access_key = S3_CONFIG['secret_access_key'] 
    config.s3_bucket   = S3_CONFIG['bucket'] 
end

，並把這個在config/amazon_s3.yml：

development: 
    access_key_id: xxxxxxxxxxxxxxxxxxxx 
    secret_access_key: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx 
    bucket: your-dev-bucket 

test: 
    access_key_id: xxxxxxxxxxxxxxxxxxxx 
    secret_access_key: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx 
    bucket: your-test-bucket 

production: 
    access_key_id: xxxxxxxxxxxxxxxxxxxx 
    secret_access_key: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx 
    bucket: your-prod-bucket

我在嘗試啓動服務器時遇到同樣的問題。 /Users/my-machine/.rvm/gems/ruby-1.9.3-p327/gems/carrierwave-0.7.1/lib/carrierwave/uploader/configuration.rb:73:in'eval'：can not convert nil轉換爲String（TypeError）。有沒有人有關於這個問題的任何其他說明。我複製了您的帖子中的所有內容，但仍然出現錯誤。 – Chapsterj 2013-01-28 17:57:22

已解決。我使用的是自述文件中陳述的過時配置，而不是文檔中的新方法。

對於carrierwave的新開發人員一定要閱讀實際的RDOC，而不是自述文件。

能否請您發佈錯誤的，這裏的正確的配置我將這個標籤在config/initializers/carrierwave.rb解決它？我試圖使用RDoc中的配置，但這使它變得更糟。也許我們正在研究不同的RDoc。 – 2011-05-22 16:36:07

我試圖在這裏發佈我的解決方案，但評論SO是如此痛苦。我將我的評論轉到「答案」。 – nickh 2011-07-25 00:08:46
