    <p>I have a Rails app with Expenses that belongs_to Vendors.</p> <p>While the user is adding a new Expense, they might need to add a new Vendor.</p> <p>I thought I could just add a button and a Vendor partial to the Expense form.</p> <p>Like this:</p> <pre><code>&lt;%= simple_form_for @expense, :html =&gt; {:class =&gt; 'form-horizontal'} do |f| %&gt; &lt;div class="span5"&gt; &lt;a data-toggle="modal" href="#vendorform"&gt; &lt;p class="pull-right btn btn-primary btn-mini"&gt;New Vendor&lt;/p&gt;&lt;/a&gt; &lt;%= render :partial =&gt; "vendors/vendorform" %&gt; &lt;/a&gt; &lt;%= f.association :vendor, :label_method =&gt; :vendor_name, :label =&gt; 'Vendor', collection: Vendor.order('vendor_name ASC') %&gt; </code></pre> <p>The _vendorform.html.erb looks like this:</p> <pre><code>&lt;div id="vendorform" class="modal hide fade" tabindex="-1" role="dialog" aria-labelledby="vendorformLabel" aria-hidden="true"&gt; &lt;div class="modal-header"&gt; &lt;a class="close" data-dismiss="modal"&gt;&amp;#215;&lt;/a&gt; &lt;h4 id="vendorformLabel"&gt;Add Vendor&lt;/h4&gt; &lt;/div&gt; &lt;div class="modal-body"&gt; &lt;%= simple_form_for Vendor.new do |f| %&gt; (bunch of fields) &lt;/div&gt; &lt;div class="modal-footer"&gt; &lt;%= f.submit 'Save Vendor', :class =&gt; 'btn btn-mini btn-primary' %&gt; &lt;a class="btn btn-mini" data-dismiss="modal" href="#"&gt;Close&lt;/a&gt; &lt;% end %&gt; &lt;/div&gt; &lt;/div&gt; </code></pre> <p>This partial shows up OK. But, the Vendor record doesn't get created. The submit of the partial actually somehow triggers the submit for the Expense. The page comes back with all of the required Expense fields red.</p> <p>I think it's posting to the Expenses controller when the <code>f.submit</code> button in the Vendor partial is pressed !!!</p> <p>Do I need something in the Expense controller?</p> <p>Or is there a better way?</p> <p>Thanks for the help!</p>

    1. COHow are you trying to create the vendor object, by clicking the submit button on the vendor form or by clicking the submit button on the expense form?

    2. COClicking the button on in the partial Vendor form. But, it looks like that is posting to the Expenses controller - don't know why?

    3. COBasically you have nested `html` form elements. You shouldn't be doing that. You should move the fields in another partial, then render that partial within `fields_for` so that the associations are also automatically created. Hope this makes sense!

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.
