    <p>I am a total node.js noobie and trying to figure out the best way to structure my application with proper separation of concerns.</p> <p>I am using mongodb via mongoose and have successfully gotten my controllers separated out using node.js modules and am trying to then separate out my models. What I've gone appears to work, but when I check the database nothing has been saved. Also, I tried a <code>console.log()</code> in the save function and nothing gets logged.</p> <p>from my server.js I have:</p> <pre><code>app.post(api.urlslug + '/messages', messagesapi.insert); </code></pre> <p>I then have a /controllers/api/messages.js:</p> <pre><code>var m = require('../../models/message'); exports.index = function(req, res, next){ res.send('all the messages...'); } exports.insert = function(req, res, next){ var message; message = new m.Message({ messagebody: req.body.messagebody }); message.save(function(err) { console.log('here we are in the save'); if(!err) { return console.log('message created'); } else { return console.log(err); } }); return res.send(message); } </code></pre> <p>and my /models/message.js looks like this:</p> <pre><code>// required modules var mongoose = require('mongoose') , db = require('../models/db'); // setup database connection mongoose.connect(db.connectionstring()); var Message = exports.Message = mongoose.model('Message', new mongoose.Schema({ messagebody: String })); </code></pre> <p>When I post to the API I get a the proper JSON back and it even has the _id field with what appears to me as a mongodb provided unique id. With that, I am having trouble understanding why it is not actually going into mongodb if it appears to be creating the object and communicating with mongodb correctly.</p>

    1. COI'm not sure at first glance, but I think you might be wrong on 'and communicating with mongodb correctly'. More likely it hasn't communicated with MongoDB, but instead Mongoose has created the _id for you (yes it's able to do it, it's part of the beauty of Mongo's Objectid spec) Still, not sure what's going wrong. You're sure `exports.insert` is called? Moverover, how have you tested 'message' isn't persisted to MongoDB? Best way to check is using the Mongo CLI on whatever platform you happen to be

    2. CO@Geert-Jan That makes sense on the _id. That is very likely that it is mongoose creating the id. Yes, I checked the MongoDB using the Mongo CLI and no document are being created.

    3. COCould it be that the title of your question isn't actually what you are asking? You talk about separation of concerns but it seems your questions should be "Why isn't my MongoDB document being saved?"

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.
