    <p>I've been trying to implement @mentions for my application using the At.js library from</p> <p><a href="https://github.com/ichord/At.js" rel="nofollow">https://github.com/ichord/At.js</a></p> <p>I'm having some issues triggering the at functionality (triggered by the callback in the code below). I have setup the following coffeescript:</p> <pre><code>$ -&gt; $("textarea").atWho "@", (query, callback) -&gt; console.log("@who") $.ajax url: "/users/mentions.json" param: q: query done: (data) -&gt; console.log("in callback") console.log(data) names = $.parseJSON(data) console.log(names) callback names </code></pre> <p>From the js and rails consoles I can see that the controller action is getting called, however no other calls are made. </p> <p>This library has been working fine for me with static data so I think that the callback syntax is an issue. Does anyone have any pointers for this?</p> <p>EDIT:</p> <p>I've adapted Nick's solution below and changed to use a get request and this works fine for querying and returning data from the rails app using the following revised code:</p> <pre><code>$ -&gt; $("textarea").atWho "@", (query, callback) -&gt; console.log("@who") $.get "/users/mentions.json", q: query, ((result) -&gt; console.log("in callback") console.log("result: ") console.log(result) names = $.parseJSON(result) console.log(names) callback names ), "json" </code></pre> <p>However there is still a problem with the parseJSON(result) line - it returns null every time. I have tried changing the json which I am sending to the very simple {"name":"james"} and it is still not returning anything - can anyone help with this issue?</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.
