    <p>When trying to create a model in Mongoose I get the following error</p> <p>[TypeError: Cannot read property 'options' of undefined]</p> <p>I have no idea what's causing it</p> <pre><code>"use strict"; var Step = require('step'); var mongoose = require('mongoose'); var Schema = mongoose.Schema; function randomFunction() { var categorySchema = new Schema({ id: Number, name: String, description: String }, { collection: 'categories' }); var Category; //... mongoose.connect('mongodb://localhost/grouping'); new Step( function() { //Connect to mongodb var db = mongoose.connection; db.on('error', console.error.bind(console, 'connection error:')); db.on('open', this); }, function() { //Create model console.log(categorySchema); //Logs the schema object right Category = mongoose.Model('Category', categorySchema); }, function(err) { console.log(err); //Error here }); //... } </code></pre> <p>I'm very new to Mongo (and fairly new to node) but I have absolutely no idea what the error message means.</p> <p>I know I have options defined in the schema but I cant see how it would be undefined, can anyone point me in the right direction?</p> <p>Note - this is a big cut out of the original code, this is the general structure (there's actually some code below <code>mongoose.Model('Cat...</code> but it gets skipped, I assume because the error is thrown by the <code>mongoose.Model</code> call as not even a <code>console.log("Hello");</code> is printed straight after it.</p> <p><strong>EDIT</strong> I've found that inside Mongoose (mongoose/lib/document.js) tries to get <code>this.schema</code> but it's undefined</p> <pre><code>function Document (obj, fields, skipId) { //Line 37 this.$__ = new InternalCache; this.isNew = true; this.errors = undefined; var schema = this.schema; //-&gt; undefined // ... </code></pre>

    1. COAre you sure, you are connected to MongoDB, the right code for connecting is `mongoose.connect('mongodb://host/database', function(err) { console.log('error occured', err); });` ?

    2. COI'll try that, thanks. I found that other connection code somewhere which worked better for me because it was seperated

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.
