    <p>I have a rails app I'm trying to set up with sortable lists using the acts_as_list plugin. The position field in the db is getting updated, but when the page is rendered, the order is not considered. I'm looking for some help, I guess. </p> <p>Here are my models...</p> <pre><code>class QuestionMembership &lt; ActiveRecord::Base belongs_to :form belongs_to :question acts_as_list end class Form &lt; ActiveRecord::Base has_many :question_memberships has_many :questions, :through =&gt; :question_memberships end class Question &lt; ActiveRecord::Base has_many :question_memberships has_many :forms, :through =&gt; :question_memberships acts_as_list end </code></pre> <p>And the sloppy view code that gives me the list...</p> <pre><code>&lt;% @form.question_memberships.each do |qm| %&gt; &lt;% q_id = "question_#{qm.id}" %&gt; &lt;li class="question" id=&lt;%= q_id %&gt; &gt; &lt;div style="color: #999; font-size: 8pt"&gt; &lt;%=h qm.question.content %&gt; &lt;/div&gt; &lt;/li&gt; &lt;%= draggable_element(q_id, :revert=&gt;true) %&gt; &lt;% end %&gt; </code></pre> <p>The drag and drop works for the reordering. The position value updates in the DB for the QuestionMembership objects and the page actually shows the reorder correctly. The problem is that on a page reload, it defaults back to whatever order it feels like. I think it defaults to the question id for the order instead of the question_membership position, but I'm not sure.</p> <p>Any ideas on how I can make it actually order on the initial render by the position field of the QuestionMembership?</p>

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.
