我正在处理一个处理图片的网络应用程序。我使用Ruby on rails，Heroku和图片，上传完成感谢回形针和亚马逊AWS S3上的存储。
当我在本地测试它时，它运行得很好，但是当我提交它并在网上测试它时，它不起作用！我可以选择要上传的文件但是当我提交时，我有一个错误：
We're sorry, but something went wrong.
If you are the application owner check the logs for more information.
图像不在亚马逊上。
这是我的代码：
观点： photo.html.erb：
<h1>New photo</h1>
<%= form_for @photo, :html => { :multipart => true } do |f| %>
<div class="field">
<%= f.file_field :image %>
</div>
<div class="action">
<%= f.submit %>
</div>
<% end %>
* show.html.erb *
型号： photo.rb：
class Photo < ActiveRecord::Base
has_attached_file :image,
:styles => { :medium => "x300", :thumb => "x100" },
:default_url => "www.google.fr",
:storage => :s3,
:s3_host_name => 's3-eu-west-1.amazonaws.com',
:bucket => 'pyloriruc',
:s3_credentials => S3_CREDENTIALS
end
环境/初始化程序： s3.rb：
if Rails.env == "production"
# set credentials from ENV hash
S3_CREDENTIALS = { :access_key_id => 'AKI*****************', :secret_access_key => 'Aiqpd******************************', :bucket => 'pyloriruc'}
else
# get credentials from YML file
S3_CREDENTIALS = Rails.root.join("config/s3.yml")
end
if Rails.env == "development"
# set credentials from ENV hash
S3_CREDENTIALS = { :access_key_id => 'A*************', :secret_access_key => 'Aiq************************', :bucket => 'pyloriruc'}
else
# get credentials from YML file
S3_CREDENTIALS = Rails.root.join("config/s3.yml")
end
这里我的heroku记录：

我不知道您是否需要更多代码来帮助我解决此问题。谢谢。
答案 0 :(得分：1)
尝试
if Rails.env == "production"
# set credentials from ENV hash
S3_CREDENTIALS = { :access_key_id => 'AKI*****************', :secret_access_key => 'Aiqpd******************************', :bucket => 'pyloriruc'}
else
# get credentials from YML file
S3_CREDENTIALS = { :access_key_id => 'AKI*****************', :secret_access_key => 'Aiqpd******************************', :bucket => 'pyloriruc'}
end
只是为了看看它是否可以解决你的问题，然后才能制作出更好的代码..
