    <p>I am using the <a href="https://github.com/crowdint/rails3-jquery-autocomplete" rel="nofollow">rails3-jquery-autocomplete gem</a> and it works neat when using it for fields that exist in the model. However, I have been trying to use it for associations and I fail to see how to make it work. So let's explain what I have:</p> <p><strong>Models</strong>:</p> <pre><code>class Receipt &lt; ActiveRecord::Base belongs_to :user end class User &lt; ActiveRecord::Base has_many :receipts end </code></pre> <p><strong>Controller</strong></p> <pre><code>class Admin::ReceiptsController &lt; AdminController autocomplete :user, :name def index @receipts = Receipt.all end def show @receipt = Receipt.find_by_id(params[:id]) end def edit @receipt = Receipt.find_by_id(params[:id]) @users = User.all end end </code></pre> <p><strong>View (form)</strong>:</p> <pre><code>&lt;%= form_for(@receipt, :url =&gt; admin_receipt_path, :html =&gt; { :multipart =&gt; true }) do |f| %&gt; &lt;div class="clearfix"&gt; &lt;%= f.label :value, "Value($)" %&gt; &lt;div class="input"&gt;&lt;%= f.text_field :value %&gt;&lt;/div&gt; &lt;/div&gt; &lt;div class="clearfix"&gt; &lt;%= f.label :user_id, "User" %&gt; &lt;div class="input"&gt; &lt;%= f.autocomplete_field :user_id, autocomplete_user_name_admin_receipts_path %&gt; &lt;/div&gt; &lt;/div&gt; ..... </code></pre> <p>The thing is... I am able to fetch user names, but I want to actually store the user id in there. The same way I would like to show the name when the admin tries to edit an existing receipt with a user associated. Something that I am able to do with this drop down:</p> <pre><code>&lt;div class="clearfix"&gt; &lt;%= f.label :user_id, "User" %&gt; &lt;div class="input"&gt;&lt;%= f.select :user_id, @users.collect {|p| [ p.name, p.id ] },{:prompt =&gt; 'Select a User'} %&gt;&lt;/div&gt; &lt;/div&gt; </code></pre> <p>I am failing to see how would I do this with this gem....</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.
