I am using Paperclip to upload multiple item images. I followed some of this tutorial <a href="http://sleekd.com/general/adding-multiple-images-to-a-rails-model-with-paperclip/" rel="nofollow">http://sleekd.com/general/adding-multiple-images-to-a-rails-model-with-paperclip/</a> My models are: Item.rb <pre><code>has_many :item_images, :dependent => :destroy accepts_nested_attributes_for :item_images, :reject_if => lambda { |l| l['item_image'].nil? } </code></pre> ItemImage.rb <pre><code>class ItemImage < ActiveRecord::Base belongs_to :item belongs_to :user #for image. Paperclip following Bootstrap sizes. has_attached_file :image, :styles => { :large => ["330x230>",:png], :medium => ["210x150>",:png], :small => ["90x90>",:png], :thumb => ["32x32>", :png] }, :default_url => '/images/missing_image_:style.png', :storage => :s3, :bucket => 'iscomp', :s3_credentials => "#{RAILS_ROOT}/config/amazon_s3.yml", :path => "iscomp/:attachment/:style/:id.:extension" validates_attachment_presence :image validates_attachment_size :image, :less_than => 5.megabytes end </code></pre> My issue is that because the images are stored on a second model, I am not able to access a default blank image when there are no images/records on the @item.item_image. If I had used paperclip directly on @item, Paperclip will return default image for me. What's the best way of doing this if I do not want to keep adding in if/unless statements whenever I call for a thumbnail?

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.
