    <p>So I have an object, that I'm using in nodejs. It looks as such:</p> <pre><code>for(var i = 0; i &lt; x.length; i++) { var sUser = x[i]; mUsers[sUser.userid] = CreateUser(sUser); ++mUsers.length; } </code></pre> <p>So I'm pulling information from an external source, and it breaks down as an array full of instances of this:</p> <pre><code>[{ name: 'Michael Lovesllamas Lankford', created: 1338420951.11, laptop: 'pc', laptop_version: null, userid: '4fc6aed7eb35c14ad6000057', acl: 0, fans: 1, points: 5, avatarid: 34 }] </code></pre> <p>and so forth.</p> <p>so that information is passed as x in the above function.</p> <pre><code>global.mUsers = {length:0} global.UserBase = { userid: -1, name: "noidea", isSuperUser: false, isDJ: false, laptop: "pc" }; process.on("registered", OnRegistered); global.OnRegistered = function(a) { //misc code here RegisterUsers(a.users); //misc code here } global.CreateUser = function(a) { var b = UserBase; b.userid = a.userid; b.name = a.name; b.laptop = a.laptop; if (a.acl &gt; 0) b.isSuperUser = true; return b; }; global.RegisterUsers = function(x) { for(var i = 0; i &lt; x.length; i++) { var sUser = x[i]; mUsers[sUser.userid] = sUser; ++mUsers.length; } </code></pre> <p>}</p> <p>Now, I've logged it in the loop, and mUsers[sUser.userid] does indeed = sUser. but when I console.log(mUsers) immediately after the loop, I get this:</p> <pre><code>{ userid1: { userid: userid3, name: name3, item: item3 }, userid2: { userid: userid3, name: name3, item: item3 }, userid3: { userid: userid3, name: name3, item: item3 } } </code></pre> <p>And I don't know why it's overwriting. Any ideas?</p>

    1. COdo you really mean `++i` and not `i++` their both quite different, when applied in `for` loops.

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.
