    <p>I have a Post model which has_many :photos. While User creating a new post, user should be also able to select photos for given post.</p> <p>I am using RAILS 3.2.9, nested_form, carrierwave and jquery-fileupload-rails gem and ryan bates <a href="http://railscasts.com/episodes/381-jquery-file-upload">railscasts</a> as a guide.</p> <p>All seems to be set up correctly, but problem is, when User choose a photo (a fileupload() function is triggered), new Post and new Photo record are created. Once I press "create post" another post record is again created.</p> <p>Any help/idea is appreciated.</p> <p>Thank you very much.</p> <p>Petr</p> <pre><code>class Post &lt; ActiveRecord::Base has_many :photos, as: :attachable, :dependent =&gt; :destroy accepts_nested_attributes_for :photos, :allow_destroy =&gt; true end class Photo &lt; ActiveRecord::Base belongs_to :attachable, polymorphic: true attr_accessible :image, :description, :post_id, :attachable_id, :attachable_type mount_uploader :image, PhotoUploader end # Post Controller def create @post = Post.new(params[:post]) @post.save end # _form.html.erb &lt;%= nested_form_for @post, :html =&gt; { :multipart =&gt; true } do |f| %&gt; &lt;%= f.fields_for :photos do |photo| %&gt; &lt;% if photo.object.new_record? %&gt; &lt;%= photo.file_field :image, id: "fileupload" %&gt; &lt;%= photo.hidden_field :id %&gt; &lt;%= photo.hidden_field :attachable_id %&gt; &lt;%= photo.hidden_field :attachable_type %&gt; &lt;% else %&gt; &lt;%= image_tag(photo.object.image.url(:thumb)) %&gt; &lt;%= photo.check_box :_destroy %&gt; &lt;% end %&gt; &lt;% end %&gt; &lt;% end %&gt; #application.js $('#fileupload').fileupload(); </code></pre>

    1. COWhat is the source of your file_upload function? That's probably your problem...

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
