Simple plugin for Mongoose which adds a findOrCreate method to models. This is useful for libraries like Passport which require it.
npm install mongoose-findorcreate
var findOrCreate = require('mongoose-findorcreate')
var ClickSchema = new Schema({ ... });
ClickSchema.plugin(findOrCreate);
var Click = mongoose.model('Click', ClickSchema);The Click model now has a findOrCreate static method
Click.findOrCreate({ip: '127.0.0.1'}, function(err, click, created) {
// created will be true here
console.log('A new click from "%s" was inserted', click.ip);
Click.findOrCreate({}, function(err, click, created) {
// created will be false here
console.log('Did not create a new click for "%s"', click.ip);
})
});You can also include properties that aren't used in the find call, but will be added to the object if it is created.
Click.create({ip: '127.0.0.1'}, {browser: 'Mozilla'}, function(err, val) {
Click.findOrCreate({ip: '127.0.0.1'}, {browser: 'Chrome'}, function(err, click) {
console.log('A click from "%s" using "%s" was found', click.ip, click.browser);
// prints A click from "127.0.0.1" using "Mozilla" was found
})
});Choose your Promise library by setting
Mongoose.Promise.
The returned Promise shall resolve to an object with keys doc and
created on success. It shall be rejected with err on failure.
// Use environment-provided Promise (necessary to silence a Mongoose warning).
mongoose.Promise = Promise;
// To a findOrCreate().
Click.findOrCreate({ip: '127.0.0.2'}).then(function (result) {
click = result.doc;
console.log('A click from', click.ip, ' using ', click.browser, ' was ', click.created ? 'created' : 'found');
