我正在使用Carrierwave上傳文件。在運行OS X 10.8的開發機器上,我可以上傳文件並按預期下載文件。尾礦的開發日誌中我看到:Carrierwave空文件 - 文件「MyDocument.pdf」無法打開,因爲它是空的
Started GET "/resources/download_file/11" for 127.0.0.1 at 2013-03-24 06:29:33 -0400
Processing by ResourcesController#download_file as HTML
Parameters: {"id"=>"11"}
Resource Load (0.2ms) SELECT "resources".* FROM "resources" WHERE "resources"."id" = ? LIMIT 1 [["id", "11"]]
Sent file /Users/scervera/rails_apps/mdn/public/uploads/resource/document/11/MyDocument.pdf (0.1ms)
Completed 200 OK in 2ms (ActiveRecord: 0.2ms)
與Capistrano的部署到我的Ubuntu 12.04服務器虛擬機後,我能上傳文件(並驗證它是物理服務器上),然而,當我點擊鏈接下載文件我收到一條消息,說:
「文件」MyDocument.pdf「無法打開,因爲它是空的。」
拖尾production.log表明這一點:
Started GET "/resources/download_file/1" for 192.168.0.90 at 2013-03-24 06:31:12 -0400
Processing by ResourcesController#download_file as HTML
Parameters: {"id"=>"1"}
Sent file /var/mdnapp/releases/20130322184251/public/uploads/resource/document/1/MyDocument.pdf (0.1ms)
Completed 200 OK in 2ms (ActiveRecord: 0.1ms)
注意,這個SQL行缺少:
Resource Load (0.2ms) SELECT "resources".* FROM "resources" WHERE "resources"."id" = ?
當我試圖打開文件時,它確實是空的。
另外,我還嘗試添加以下到我的deploy.rb,但在這是有益的,並沒有解決這個特定的問題:
set :shared_children, shared_children + %w{public/uploads}
其他細節 我有一個方法resources_controller稱爲download_file。見下:
def download_file
@resource = Resource.find(params[:id])
send_file(@resource.document.path,
:type => 'application/pdf',
:disposition => 'attachment',
:url_based_filename => true)
end
在我看來,我有一個鏈接標記,調用此方法。請參見下面視圖代碼:
<% if @resources.empty? %>
<p>There are no resources available at this time.</p>
<% else %>
<% @resources.each do |resource| %>
<div class="resource_wrap clearfix">
<h1><%= resource.title.html_safe %></h1><h2><%= resource.subtitle.html_safe %></h2>
<p><%= image_tag resource.image_url(:wallet).to_s %><%= resource.description.html_safe %></p>
<div id="attachments">
<% if resource.document? %>
<p>Get the resource:<%= link_to 'Download File', :action => 'download_file', :id => resource.id %></p>
<% end %>
<% if resource.video? %>
<p>Get the video:<%= link_to 'Download Video', :action => 'download_video', :id => resource.id %></p>
<% end %>
</div>
</div>
<% end %>
<% end %>
我運行軌道3.2.11,紅寶石1.9.3p194,carrierwave 0.8.0,rmagick 2.13.2
請讓我知道如果您需要任何其他細節。
同樣的問題在這裏,謝謝!我使用的是Nginx,但由於某種原因仍然使用我認爲適用於Apache的「X-sendfile」。我將它設置爲'config.action_dispatch.x_sendfile_header ='X-Accel-Redirect'#for nginx',因爲它應該是,並且它工作正常。 – ryan2johnson9 2016-04-04 23:57:08
