    <p>I'm making a small website for school, it's an image based gallery where you can vote and comment. At the moment they're all on one page and all have a rating form.</p> <p>So at the moment the default rating is working, but I cant update it (I frankly don't know how) Here's how it looks now</p> <p><a href="http://i.imgur.com/M4ZOtUG.png" rel="nofollow">http://i.imgur.com/M4ZOtUG.png</a></p> <p>The user is supposed to enter a rating, and then it should show the new value of the rating.</p> <p>I'm pretty close since when I rate the first image 3; I get: (in my console)</p> <p>"c1, 3"</p> <p>And when I rate the 4th image 5, I get:</p> <p>"c4, 5"</p> <p>etc.</p> <p>Now how do I update the default rating? (default ratings are set in my collection)</p> <p>Example code of image in collection</p> <pre><code>{image: "images/gifs/water.gif", rating: 5, comments: "Love the detail in this one!", title:"Water", category:"Nature"} </code></pre> <p>Here's how it's in my view:</p> <pre><code>gifs_html += '&lt;td&gt;' + "&lt;span class=\"stars\"&gt;" + gifs[gif].get("rating") + ".0&lt;/span&gt;" + "\n" + "&lt;form data-id=\"" + gifs[gif].cid + "\"&gt;&lt;input type=\"text\" name=\"amount\" size=\"5\" value=\"\"/&gt;" + "\n" + "&lt;input type=\"submit\" value=\"Rate\"&gt;" + "&lt;input type =\"hidden\" name=\"cid\" value=\"" + gifs[gif].cid + "\"&gt; &lt;/form&gt;" + '&lt;/td&gt;'; </code></pre> <p>Then I'm giving this jquery function (to update the star image)</p> <pre><code>$('span.stars').stars(); </code></pre> <p>and this event</p> <pre><code> events:{ 'submit form':function(ev){ var $form = $(ev.currentTarget); var id = $form.data("id"); var rating = $("input[name=amount]", $form).val(); console.log(id + ", " + rating); return false; } </code></pre> <p>Help would be greatly appreciated. Thanks.</p>

    1. COWhat do you mean with default rating? Do you mean the arithmetic mean which is the sum of all the ratings divided by number of votes?

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.
