    <p>I can't get an image to show in a Formtastic form with radio buttons. Here's my form. The :activity_id, :as => radio is the issue:</p> <pre><code>&lt;%= semantic_form_for @event do |f| %&gt; &lt;%= f.inputs do %&gt; &lt;%= f.input :date, :as =&gt; :string, :input_html =&gt; { :class =&gt; 'jquery-ui-date'} %&gt; &lt;%= f.input :date, :as =&gt; :hidden, :input_html =&gt; { :id =&gt; 'date-alt'} %&gt; &lt;%= f.input :activity_id, :as =&gt; :radio, :collection =&gt; Activity.all %&gt; &lt;% end %&gt; &lt;%= f.actions do %&gt; &lt;%= f.action :submit, :as =&gt; :button %&gt; &lt;%= f.action :cancel, :as =&gt; :link %&gt; &lt;% end %&gt; &lt;% end %&gt; </code></pre> <p>That works fine as far as showing the radio button, the activity name, and saving correctly on submit. But I need to show the image that goes with the activity because most of my users cannot read and must rely on images and TTS. I've got the images showing in my other views.</p> <p>I've tried dozens of combinations of things with :hint, and :wrapper_html, and image_tag and so on. So many variations I've become scrambled in the brain-pan.</p> <p>A sample attempt:</p> <pre><code>&lt;%= f.input :activity_id, :as =&gt; :radio, :collection =&gt; Activity.all, :hint =&gt; f.template.image_tag(f.object.image_url(:thumb)) %&gt; </code></pre> <p>This gives me an "undefined method `image_url'" error. Yet this :hint works fine elsewhere.</p> <p>I'll switch back to a standard html.erb view if that helps, but my problem there was a "stringify_keys" error I was unable to solve.</p> <p>There's gotta be a way. Please? Thanks much. . .</p>

    1. COWhy can't you use:hint => f.template.image_tag(@event.image_url(:thumb))

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.
