maps the logicalid
attribute to the required_id
physical-layer mongo id. In the current version ofsails-mongo
, you should not sort byid
.
Installation
Install from NPM.
$ npm install sails-mongo --save
Usage
Note: The following instructions are for apps using at least Sails v0.10.x, up through v0.12.x.
- For help with legacy versions of Sails, see #Legacy Usage below.
- To use sails-mongo with the Sails v1 / Waterline 0.13 prerelease, see the 1.0 branch of sails-docs.
After installing this adapter as a dependency of your Sails app, make this particular Mongo database your default datastore by adding the following settings to the files in your config folder:
// config/connections.js
module.exports.connections = {
localMongoDb: {
adapter: 'sails-mongo',
host: 'localhost', // defaults to `localhost` if omitted
port: 27017, // defaults to 27017 if omitted
user: 'username_here', // or omit if not relevant
password: 'password_here', // or omit if not relevant
database: 'database_name_here' // or omit if not relevant
}
};
// config/models.js
module.exports.models = {
'connection': 'localMongoDb'
};

What about production?
In production, use config/env/production.js and/or environment variables.

FAQ
What about MongoDB urls?
You can follow MongoDB URI Connection Settings specification on how to define a connection string URI.
Following there is an example on how to configure the connection to your MongoDB server using a URL. e.g.:
module.exports.connections = {
localMongoDb: {
adapter: 'sails-mongo',
url: 'mongodb://heroku_12345678:[email protected]:29017/heroku_12345678'
}
};
You could also use an environment variable, to ease your deployments, for example, to Heroku , as follows:
module.exports.connections = {
localMongoDb: {
adapter: 'sails-mongo',
url: process.env.MONGODB_URI
}
};
This would be useful if, for instance, your Heroku env variables looked like:
MONGODB_URI=mongodb://heroku_12345678:[email protected]:29017/heroku_12345678
It must be noted though, that if you provide a url
configuration, then, database
, user
, password
, host
and port
configuration options are ignored.
What about a MongoDB deployment that is part of a Replica Set?
For example:
MONGODB_URI=mongodb://mongodbserver01:27017,mongodbserver02:27017,mongodbserver03:27017/my-app-datatabase?replSet=my-replica-set-name&readPreference=nearest&slaveOk=true
The previous configuration will set three MongoDB servers, named mongodbserver01
, mongodbserver02
and mongodbserver03
, all using port 27017
, connecting to the my-app-database
and using my-replica-set-name
as the replica set. It also sets the readPreference
to nearest
and allows slave connections, with slaveOk
set to true
Legacy usage
####Using with Sails v0.9.x
Add the mongo config to the config/adapters.js
file.
module.exports.adapters = {
'default': 'mongo',
mongo: {
module: 'sails-mongo',
host: 'localhost',
port: 27017,
user: 'username',
password: 'password',
database: 'your mongo db name here',
wlNext: {
caseSensitive: false
}
}
};
Note: You can also use the old v0.8.x
syntax as well, see next section for details.
Replication/Replica Set can be setup by adding the following options to the mongo
object,
with your own replica details specified:
replSet: {
servers: [
{
host: 'secondary1.localhost',
port: 27017 // Will override port from default config (optional)
},
{
host: 'secondary2.localhost',
port: 27017
}
],
options: {} // See http://mongodb.github.io/node-mongodb-native/api-generated/replset.html (optional)
}
Note: Replica set configuration is optional.
Using with Sails v0.8.x
module.exports.adapters = {
'default': 'mongo',
mongo: {
module: 'sails-mongo',
url: 'mongodb://USER:PASSWORD@HOST:PORT/DB'
}
};
Don't forget that Mongo uses the ObjectId type for ids.

Special thanks
Thanks so much to Ted Kulp (@tedkulp) and Robin Persson (@prssn) for building the first version of this adapter back in 2013. Since then, it has evolved into a core adapter within the framework.
