    <p>I am working on a app that plays music files. Part of the app lists tracks available to be played in a rails table:</p> <pre><code>&lt;table class="table table-hover"&gt; &lt;thead&gt; &lt;tr&gt; &lt;th&gt;#&lt;/th&gt; &lt;th&gt;Title&lt;/th&gt; &lt;th&gt;Featured Artist&lt;/th&gt; &lt;th&gt;Length&lt;/th&gt; &lt;th&gt;Size&lt;/th&gt; &lt;th&gt;&lt;/th&gt; &lt;th&gt;&lt;/th&gt; &lt;/tr&gt; &lt;/thead&gt; &lt;% album.tracks.each do |t| %&gt; &lt;tbody&gt; &lt;tr&gt; &lt;td&gt;&lt;%= t.track_number.to_s.rjust(2, '0') %&gt;&lt;/td&gt; &lt;td&gt;&lt;%= t.title %&gt;&lt;/td&gt; &lt;td&gt;&lt;%= t.artists.map{ |a| [a][0].name }.join(", ") %&gt;&lt;/td&gt; &lt;td id="time"&gt;&lt;%= "#{((t.length) / 60)}:""#{(t.length % 60).to_s.rjust(2, '0')}" %&gt;&lt;/td&gt; &lt;td&gt;&lt;%= "#{t.size} MB" %&gt;&lt;/td&gt; &lt;td&gt; &lt;div class="btn-group btn-group-hover pull-left" data-id="&lt;%= t.id%&gt;" data-url="&lt;%= t.track_path%&gt;"&gt; &lt;a class="btn btn-mini icon-play"&gt;&lt;/a&gt; &lt;a class="btn btn-mini icon-volume-up"&gt;&lt;/a&gt; &lt;a class="btn btn-mini icon-trash"&gt;&lt;/a&gt; &lt;/div&gt; &lt;/td&gt; &lt;td&gt;&lt;%= rating_for t, "sound" %&gt;&lt;/td&gt; &lt;td&gt;&lt;/td&gt; &lt;/tr&gt; &lt;/tbody&gt; &lt;% end %&gt; &lt;/table&gt; </code></pre> <p>When I click the play button and the track begins to play, I want to append the track time column with the current track time data so it looks like this: 4:34/00:10 Where the time on the left I have in the table already and I want to append the new data after the /.</p> <p>My javascript code for soundmanager looks like this:</p> <pre><code> whileplaying: function() { var track_time = $('#time').html(); var seconds = Math.round(this.position/1000); var r = seconds % 60; var m = Math.floor(seconds / 60); var duration = (m &lt; 10 ? '0' + m : m) + ":" + (r &lt; 10 ? '0' + r : r); $('#time').html('&lt;p&gt;' + duration + '&lt;/p&gt;'); </code></pre> <p>Problem is that this current code completely replaces the current track time value instead of appending it, and if I use</p> <pre><code>$('#time').append('&lt;p&gt;' + duration + '&lt;/p&gt;'); </code></pre> <p>or</p> <pre><code>$('#time').text('&lt;p&gt;' + duration + '&lt;/p&gt;'); </code></pre> <p>It writes a new value in addition to the existing value which eventually scrolls across the page instead of simply replacing the existing data with the new values in place.</p> <p>Any ideas on how to do this? I'm very new to development and been stuck on this for about 2 days now.</p> <p>Thanks.</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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
