How to use a specific collection Mongoose-Express-Mongodb (MEAN STACK) - node.js

Question

I'm getting started with the MEAN STACK, so I took their project (about posting articles), and I'm trying to costomize it in order to get the list of all flows that i can filter with angularjs and also findOne by id.
I followed the same thing that they did for articles to create JS files related to flows (flow is my object). So I have a collection named flows that I imported to the same db used by the MEAN STACK (db == mean-dev) and I tryed this code in:
// myApp/serves/models/flow.js
'use strict';
var mongoose = require('mongoose'),
Schema = mongoose.Schema;
// Flow Schema
var FlowSchema = new Schema({
_id: {
type: Number,
default: ''
},
name: {
type: String,
default: '',
trim: true
},
Clients: {
type: Array,
default: '',
trim: true
},
DP Prot: {
type: String,
default: ''
}
/* And 15 others attributes...*/
});
/** Statics */
FlowSchema.statics.load = function(id, cb) {
this.findOne({
_id: id
}).exec(cb);
};
// Define the collection
mongoose.model('Flow', FlowSchema);
And the controllers code:
// servers/controllers/flows.js
'use strict';
/**
* Module dependencies.
*/
var mongoose = require('mongoose'),
Flow = mongoose.model('Flow'),
_ = require('lodash');
/**
* Find flow by id
*/
exports.flow = function(req, res, next, id) {
Flow.load(id, function(err, flow) {
if (err) return next(err);
if (!flow) return next(new Error('Failed to load flow ' + id));
req.flow = flow;
next();
});
};
/**
* New code count Flows
*/
exports.compte = function(req, res) {
var c;
flow.count({}, function(err, count) {
if (err) return next(err);
c = count;
res.jsonp (count);
});
};
/**
* Show Flow
*/
exports.show = function(req, res) {
res.jsonp(req.flow);
};
/**
* List of Flows
*/
exports.all = function(req, res) {
Flow.find().sort('-name').populate('name', 'application').exec(function(err, flows) {
if (err) {
res.render('error', {
status: 500
});
} else {
res.jsonp(flows);
}
});
};
I added also routes... But it doesn't work, do you think that I made some mistakes? thank you in advance for your help

Answer 1

The documentation shows you how: http://mongoosejs.com/docs/guide.html#collection
You can explicitly choose a collection when creating the Schema:
// Flow Schema
var FlowSchema = new Schema({
/* attributes...*/
}, {
collection: 'my-collection'
});
Or you can set it on the created schema later:
// Flow Schema
var FlowSchema = new Schema({
/* attributes...*/
});
FlowSchema.set('collection', 'my-collection');
This was added in Mongoose 3.4 I believe, so check the verison of Mongoose you are using.

See this post for your query on enforcing a collection name:
Mongoose -- Force collection name
var mySchema = new Schema({
foo: bar
}, { collection: qux });
where qux is your collection, assuming you connected to the correct db in your mongo-connect.
