    <p><code>print user_dic[id]</code> displays the right result <code>PersonA</code>. This is when I input the id manually.</p> <pre><code>user_stream = {u'2331449': u'PersonB', u'17800013': u'PersonA'} user_dic= {} for item in user_stream: user_dic[item['id']] = item['name'] id = '17800013' print user_dic[id] #returns the right value </code></pre> <p>However, when I try to put the <code>user_id</code> through a for loop that iterates through json I get an error: <code>KeyError at 17800013</code> for the line <code>name = user_dic[user_id]</code>. I don't understand why the <code>user_dic[id]</code> works when manually inputting the id, but <code>user_dic[user_id]</code> doesn't work when going through the for loop even though the input is the same. </p> <pre><code>#right fql query fql_query = "SELECT created_time, post_id, actor_id, type, updated_time, attachment FROM stream WHERE post_id in (select post_id from stream where ('video') in attachment AND source_id IN ( SELECT uid2 FROM friend WHERE uid1=me()) limit 100)" fql_var = "https://api.facebook.com/method/fql.query?access_token=" + token['access_token'] + "&amp;query=" + fql_query + "&amp;format=json" data = urllib.urlopen(fql_var) fb_stream = json.loads(data.read()) fb_feed = [] for post in fb_stream: user_id = post["actor_id"] name = user_dic[user_id] #this is the line giving me trouble title = post["attachment"]["name"] link = post["attachment"]["href"] video_id = link[link.find('v=')+2 : link.find('v=')+13] fb_feed.append([user_id, name, title, video_id]) </code></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.

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