    <p>I've been sifting through many jQuery ajax tutorials and attempting to incorporate it with my Play! app but I'm not quite understanding a few things. Is it possible someone could explain how to do the following through Ajax calls: </p> <p>1) Suppose I want to retrieve a list of Contacts from a controller (each Contact has name, phone, email). Does the controller need to "build" the proper response for the template? What does the controller look like? What does the javascript look like to retrieve it?</p> <p>2) For adding/updating a new Contact through an ajax call, what does the javascript look like?</p> <p>Here is code for an example of the explanation above (not using ajax):</p> <hr> <p><strong>Controller:</strong></p> <pre> public static void list() { List contacts= Contact.fetchAll(); render(contacts); } public static void add(String name, String phone, String email) { Contact contact = new Contact(); contact.name = name; contact.phone = phone; contact.email = email; contact.save(); } public static void update(Long id, String name, String phone, String email) { Contact contact = Contact.findById(id); contact.name = name; contact.phone = phone; contact.email = email; contact.save(); } </pre> <p><br/></p> <p><strong>Template (lists all contacts):</strong></p> <pre> #{list contacts, as:'contact'} ${contact.name} ${contact.phone} ${contact.email} #{/list} </pre> <p><br/></p> <p><strong>Template (add contact):</strong></p> <pre>#{form @Contacts.add(), id:'form'}</pre> <pre><code>&lt;input type="text" name="name" /&gt; &lt;input type="text" name="phone" /&gt; &lt;input type="text" name="email" /&gt; &lt;input type="submit" value="Add" /&gt; </code></pre> <pre>#{/form}</pre>

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.

SQuiL has stopped working due to an internal error.

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