    copied!<p>I have rewritten this question as the other one seemed too verbose. I have the following model structure and am interested in having a set of files uploaded (2 at a time via a builder). I am not sure if the polymorphic relat</p> <pre><code>class Item &lt; ActiveRecord::Base has_many :assets, :as =&gt; :assetable, :dependent =&gt; :destroy accepts_nested_attributes_for :assets, :allow_destroy =&gt; true, :reject_if =&gt; lambda { |a| a[:asset].blank? } attr_accessible :assets_attributes, :asset ... end class Asset &lt; ActiveRecord::Base belongs_to :assetable, :polymorphic =&gt; true attr_accessible :name, :user_id, :description ... ... end </code></pre> <p>I have copied out the entirety of the form: </p> <pre><code>&lt;form accept-charset="UTF-8" action="/arc/items/70" class="edit_item" enctype="multipart/form-data" id="edit_item_70" method="post"&gt;&lt;div style="margin:0;padding:0;display:inline"&gt;&lt;input name="utf8" type="hidden" value="&amp;#x2713;" /&gt;&lt;input name="_method" type="hidden" value="put" /&gt;&lt;input name="authenticity_token" type="hidden" value="NnaCxwmfy2zT8MnN7oNQnOx0xYXkgKUs+NbIh8+8cL4=" /&gt;&lt;/div&gt; &lt;div class='files'&gt; &lt;input id="item_assets_attributes_70_asset" name="item[assets_attributes][70][asset]" type="file" /&gt; &lt;input id="item_assets_attributes_70_description" name="item[assets_attributes][70][description]" size="30" type="text" /&gt; &lt;input id="item_assets_attributes_71_asset" name="item[assets_attributes][71][asset]" type="file" /&gt; &lt;input id="item_assets_attributes_71_description" name="item[assets_attributes][71][description]" size="30" type="text" /&gt; &lt;/div&gt; &lt;input name="commit" type="submit" value="Update Menu item" /&gt; &lt;/form&gt; </code></pre> <p>and here is the controller for interacting with it: </p> <pre><code>class ItemsController &lt; ApplicationController ... def update item=params[:item] item[:assets_attributes].values do |v| v[:asset][:user_id]=3 # just hard-code it to see if workig end if @item.update_attributes(item) flash[:notice]="Menu Item has been updated #{undo_link}" else flash[:notice]="Menu Item has not been updated" end end </code></pre> <p>In my asset class, the user_id NEVER gets set. How would I make this work? I obviously want to get the current_user.id.</p> <p>thx</p> <p><strong>edit #1</strong> </p> <p>Using Rails 3.1</p> <p><strong>edit 2</strong></p> <p>One thing that I've noticed is that if I set an instance variable in the loop and then debug it into the view, it wasn't set meaning that this loop isn't even running. </p> <pre><code>item[:assets_attributes].values do |v| v[:user_id]=3 @a="here is a string" end </code></pre> <p>I have also updated the Item model with the appropriate attr_accessible for the item class.</p>
