    <p>I have a form that looks like this:</p> <pre><code>&lt;%= form_tag site_update_admin_settings_path, :method =&gt; :put do %&gt; &lt;fieldset&gt; &lt;legend&gt; &lt;h2&gt;Default Meta Information&lt;/h2&gt; &lt;/legend&gt; &lt;% for setting in @settings[:default_meta] %&gt; &lt;div class="form-group"&gt; &lt;label&gt;&lt;%= setting.name %&gt;&lt;/label&gt; &lt;span class="help-block"&gt;&lt;%= setting.description %&gt;&lt;/span&gt; &lt;input type="text" class="form-control" name="settings[&lt;%= setting.id %&gt;]" value="&lt;%= setting.value %&gt;" /&gt; &lt;/div&gt; &lt;% end %&gt; &lt;/fieldset&gt; &lt;fieldset&gt; &lt;legend&gt; &lt;h2&gt;Social Media Information&lt;/h2&gt; &lt;/legend&gt; &lt;% for setting in @settings[:social_media] %&gt; &lt;div class="form-group"&gt; &lt;label&gt;&lt;%= setting.name %&gt;&lt;/label&gt; &lt;span class="help-block"&gt;&lt;%= setting.description %&gt;&lt;/span&gt; &lt;input type="text" class="form-control" name="settings[&lt;%= setting.id %&gt;]" value="&lt;%= setting.value %&gt;" /&gt; &lt;/div&gt; &lt;% end %&gt; &lt;/fieldset&gt; &lt;fieldset&gt; &lt;legend&gt; &lt;h2&gt;Analytics Information&lt;/h2&gt; &lt;/legend&gt; &lt;% for setting in @settings[:analytics] %&gt; &lt;div class="form-group"&gt; &lt;label&gt;&lt;%= setting.name %&gt;&lt;/label&gt; &lt;span class="help-block"&gt;&lt;%= setting.description %&gt;&lt;/span&gt; &lt;input type="text" class="form-control" name="settings[&lt;%= setting.id %&gt;]" value="&lt;%= setting.value %&gt;" /&gt; &lt;/div&gt; &lt;% end %&gt; &lt;/fieldset&gt; &lt;%= submit_tag "Save Settings", class: "btn btn-primary" %&gt; &lt;% end %&gt; </code></pre> <p>The form ends up with about 10 fields on it that can be edited. The values for each field maps to the value column for each record in the database. An example of the database table looks like this:</p> <pre><code>| id | name | value | ------------------------------------------------------- | 1 | site_title | Page Title | | 2 | twitter_username | TwitterHandle | </code></pre> <p>So basically, the form fields turn into an array of settings that would be held in <code>params[:settings]</code>. The settings param holds key value pairs (id => value) for each field. The form only updates the value column for a specific row (determined by the id). I have the form submitting and creating the <code>params[:settings]</code> hash but haven't figured out how to get the controller to update the records. Thoughts? Please let me know if you need more information as well.</p> <p><strong>UPDATE:</strong> In the params hash, <code>settings</code> looks like this:</p> <pre><code>"settings"=&gt;{"1"=&gt;"Website Title", "5"=&gt;"TwitterHandle", "10"=&gt;"FooBar"} </code></pre> <p>The key is the id for the settings table record and the value is what needs to go to the value column in the settings table.</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.
