    <p>This is my Schema:</p> <pre><code>var userschema = new mongoose.Schema({ user: String, imagen: [{ name: String, author: String, date: { type: Date, default: Date.now }, }], follow: [String] }); </code></pre> <p>And this is the code:</p> <pre><code>usermodel.findOne({ user: req.session.user }, function (err, user){ usermodel.find({ _id: {$in: user.follow } }, function (err, images){ console.log(images); if (err) throw err; res.render('home.ejs', { user: user, following: images }); }); }); </code></pre> <p>The follow array in the Schema contains the <code>_id</code>s of the users that the actual user is following. I'm trying to get an output like this:</p> <pre><code>{ _id: 50fd9c7b8e6a9d087d000006, imagen: [ { name: 'fff.png', author: 'foo', _id: 50fd9ca2bc9f163e7d000006, date: Mon Jan 21 2013 20:53:06 GMT+0100 (CET) }, { name: 'mmm.png', author: 'foo', _id: 50fda83a3214babc88000005, date: Mon Jan 21 2013 21:41:34 GMT+0100 (CET) } ] }, { _id: 50fd9d3ce20da1dd7d000006, imagen: [ { name: 'ddd.jpg', author: 'faa', _id: 50fda815915e068387000005, date: Mon Jan 21 2013 21:42:57 GMT+0100 (CET) } ] } </code></pre> <p>And I'm trying to get an output similar at this, for example:</p> <pre><code> { [ { name: 'fff.png', author: 'foo', _id: 50fd9ca2bc9f163e7d000006, date: Mon Jan 21 2013 20:53:06 GMT+0100 (CET) }, { name: 'ddd.png', author: 'faa', _id: 50fda815915e068387000005, date: Mon Jan 21 2013 21:42:34 GMT+0100 (CET) }, { name: 'mmm.png', author: 'foo', _id: 50fda83a3214babc88000005, date: Mon Jan 21 2013 21:41:34 GMT+0100 (CET) } ] } </code></pre> <p>I think that what I want is imposible, or very complex, is there any solution for this...?</p> <p>Thank's advance!</p>

    1. COYou may use `array1.concat(array2)` with a loop to join all `imagen` arrays together and sort the result array by date after that. I don't think that mongoose sorting will help here. Hope i understood your question in the right way.

    2. COBut everything that I do inside a `for`loop, for example, it disappears when the loop ends, and I do something with the data used inside the loop, using it outside the loop, the data is the same, the for loop doesn't change it. I guess because I have to code it in a asynchronous way.

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.
