    <p>I have a GalleryPhoto model with a paperclip attachment that gets processed into a number of styles. Some styles need to be publicly readable; some need to be private.</p> <p>Here's my model:</p> <pre><code>class GalleryPhoto &lt; ActiveRecord::Base has_attached_file :image, :storage =&gt; :s3, :bucket =&gt; ":bucket.myapp_#{Rails.env == 'production' ? 'production' : 'development'}", :path =&gt; "images/galleries/:gallery_id/:id/:style_:id.:extension", :url =&gt; "/images/galleries/:gallery_id/:id/:style_:id.:extension", :s3_credentials =&gt; { :access_key_id =&gt; 'XXXXXXXXX', :secret_access_key =&gt; 'XXXXXXXXX' }, :s3_permissions =&gt; { :thumbnail =&gt; :public_read, :small =&gt; :public_read, :medium =&gt; :public_read, :large =&gt; :public_read, :small_download =&gt; :private, :original =&gt; :private }, :styles =&gt; { :thumbnail =&gt; { :geometry =&gt; "80x80&gt;" }, :small =&gt; { :geometry =&gt; "200x200&gt;" }, :medium =&gt; { :geometry =&gt; "400x400&gt;" }, :large =&gt; { :geometry =&gt; "600x600&gt;" }, :small_download =&gt; { :geometry =&gt; "600x600" } } end </code></pre> <p>Here's my paperclip initializer:</p> <pre><code>Paperclip.interpolates :bucket do |attachment, style| [:original, :small_download].include?(style) ? "private" : "public" end Paperclip.interpolates :gallery_id do |attachment, style| attachment.instance.gallery_id end </code></pre> <p>I have four buckets as such:</p> <pre><code>private.myapp_development private.myapp_production public.myapp_development public.myapp_production </code></pre> <p>The private.xxx buckets shouldn't be publicly accessible, but the public.xxx buckets should be publicly readable.</p> <p>I can get the app to serve the styles that have been marked public in the public buckets, but I cannot do uploads or have my download action, which serves the private styles, work.</p> <p>Here's the log when I try to do an upload:</p> <pre><code>[paperclip] Saving attachments. [paperclip] saving images/galleries/242/22034/original_22034.jpg (0.8ms) ROLLBACK Completed 500 Internal Server Error in 8013ms Errno::EPIPE (Broken pipe): app/controllers/gallery_photos_controller.rb:13:in `create' </code></pre> <p>Here's the log when I try to use my download action for the private styles:</p> <pre><code>Sent file images/galleries/222/19515/original_19515.jpg (0.2ms) Completed 500 Internal Server Error in 861ms ActionController::MissingFile (Cannot read file images/galleries/222/19515/original_19515.jpg): app/controllers/gallery_photos_controller.rb:22:in `download' </code></pre> <p>What am I missing?</p> <pre><code>rails 3.1.1 paperclip 2.7.0 aws-sdk 1.3.7 </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
