    <p>First Initialize FB Javascript SDK as following.</p> <pre><code>&lt;div id="fb-root"&gt;&lt;/div&gt; &lt;script&gt; window.fbAsyncInit = function() { // init the FB JS SDK FB.init({ appId : 'YOUR_APP_ID', // App ID from the App Dashboard channelUrl : '//WWW.YOUR_DOMAIN.COM/channel.html', // Channel File for x-domain communication status : true, // check the login status upon init? cookie : true, // set sessions cookies to allow your server to access the session? xfbml : true // parse XFBML tags on this page? }); // Additional initialization code such as adding Event Listeners goes here }; // Load the SDK's source Asynchronously (function(d){ var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0]; if (d.getElementById(id)) {return;} js = d.createElement('script'); js.id = id; js.async = true; js.src = "//connect.facebook.net/en_US/all.js"; ref.parentNode.insertBefore(js, ref); }(document)); &lt;/script&gt; </code></pre> <p>The above code will initialize your FB SDK. Now in JavaScript write following function. Refer <a href="https://developers.facebook.com/docs/reference/javascript/FB.login/" rel="nofollow">this document</a> for more details.</p> <pre><code>function initiateFB Login() { FB.login(function(response) { if (response.authResponse) { //Login Success if you want you can initiate request for friend list here only. FB.api('/me/friends/fields=id,username', function(resp) { /// Process the resp over here. This resp will be JSON response of friend request } ); } else { console.log('User cancelled login or did not fully authorize.'); } }); } </code></pre> <p>You can get the username i.e. FB User Name. Below is the request for that.</p> <pre><code>me/friends?fields=id,username </code></pre> <p>This request will give you a JSON response of following format. </p> <pre><code>{ "data": [ { "id": "FB_ID", "username": "FB_USER_NAME" }, { "id": "FB_ID", "username": "FB_USER_NAME" } ] } </code></pre> <p>You can parse this and get the username.</p> <p>Hope this helps.</p> <p>Thanks</p> <p>Kaushik</p>

    2. COOK got you. Before making this request are you asking using user to login to FB in your application? Once you do that an access token will be assigned to your application and further FB Graph API call will be able to use it. As a side note once an access token is issued then it is valid for about 2 hours

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.
