    <p>I have set up my models to use a polymorphic Image model. This is working fine, however I am wondering if it is possible to change the :styles setting for each model. Found some examples using STI (Model &lt; Image) However this is not an option for me, because I am using a has_many relation.</p> <p>Art</p> <pre><code>has_many :images, :as =&gt; :imageable </code></pre> <p>Image</p> <pre><code>belongs_to :imageable, :polymorphic =&gt; true has_attached_file :file, :styles =&gt; { :thumb =&gt; "150x150&gt;", :normal =&gt; "492x600&gt;"} #Change this setting depending on model </code></pre> <h2>UPDATE</h2> <p>I tried starting up a debugger inside the Proc method. Only fields related to the attached file is populated:</p> <pre><code>run'irb(Image):006:0&gt; a.instance =&gt; #&lt;Image id: nil, created_at: nil, updated_at: nil, imageable_id: nil, imageable_type: nil, file_file_name: "IMG_9834.JPG", file_content_type: "image/jpeg", file_file_size: 151326, file_updated_at: "2010-10-30 08:40:23"&gt; </code></pre> <p>This is the object from ImageController#create</p> <pre><code>ImageController#create @image =&gt; #&lt;Image id: nil, created_at: nil, updated_at: nil, imageable_id: 83, imageable_type: "Art", file_file_name: "IMG_9834.JPG", file_content_type: "image/jpeg", file_file_size: 151326, file_updated_at: "2010-10-30 08:32:49"&gt; </code></pre> <p>I am using paperclip (2.3.5) and Rails 3.0.1. No matter what I do the a.instance object is the image with only the fields related to the attachment populated. Any ideas?</p> <h2>UPDATE2</h2> <p>After reading a lot on the Paperclip forum I don't believe it's possible to access the instance before it has been saved. You can onlye see the Paperclip stuff and that's it.</p> <p>I got around this problem by presaving the image from the Image controller with a before filter - without the attachment</p> <pre><code> before_filter :presave_image, :only =&gt; :create ... private def presave_image if @image.id.nil? # Save if new record / Arts controller sets @image @image = Image.new(:imageable_type =&gt; params[:image][:imageable_type], :imageable_id =&gt; params[:image][:imageable_id]) @image.save(:validate =&gt; false) @image.file = params[:file] # Set to params[:image][:file] if you edit an image. end end </code></pre>

    1. COperhaps it is really due to the polymorphic association - or something similar, at least you have now a solution.

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.
