    <p>I'm trying to save a document in my collection and if the save is successful, return the _id of this same document. The problem is I get an undefined value to my _id in both case, either the created model from mongoose or from the callback return. Basically, my only way of getting the _id would be to search the document by one of its properties, and then get the value. This approach isnt what I want, knowing what im currently trying to do should work.</p> <pre><code>var createTrophy = new Trophy({ name : post.name, accessCode : post.password, description : post.description, members : [id] }); Trophy.findOne({name:post.name}, function(err, trophy) { if(err){ console.log('Mongoose: Error: ' + err); res.send('Error db query -&gt; ' + err); } else if(trophy){ console.log('Trophy ' + trophy.name + ' already existant'); res.send('Trophy ' + trophy.name + ' already existant'); }else{ createTrophy.save(function(err, doc){ var uid = createTrophy._id; if (err) { console.log('Error in trophy saving:' + err); res.send('Error in trophy saving:' + err); }else{ User.findOne({_id:post.id}, function(err, user) { if(err){ console.log('Mongoose: Error: ' + err); res.send('Error db query -&gt; ' + err); } else if(user){ console.log(doc._id + ' ' + uid); user.trophyLink = doc._id; res.send(user); //user.save(function(err){ // if(err){res.send('Couldnt update trophy of profile');} //}); } else{ console.log('User id Inexistant'); res.send('User id Inexistant'); } }); } }); } }); }); </code></pre> <p>The Schema</p> <pre><code> var Trophy = new Schema({ _id : ObjectId, name : String, accessCode : String, description : String, //reference to User ID members : [Number], comments :[Comment] }); </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.
