kriskowal's Q support for mongoose.

for mongodb native nodejs driver, see mongo-q.

usage

to apply Q with default suffix 'Q':

var mongoose = require('mongoose-q')(require('mongoose'));
// verbose way: mongooseQ is unused
var mongoose = require('mongoose'),
    mongooseQ = require('mongoose-q')(mongoose)
// shortest way: mongoose will be loaded by mongoose-q
var mongoose = require('mongoose-q')();

to apply another Q implementation(since v0.0.15):

var mongoose = require('mongoose-q')(require('mongoose'), {q:require('q-bluebird')});

use Q-applied model statics:

SomeModel.findByIdQ(....blahblah...)
  .then(function (result) { ... })
  .catch(function (err) { ... })
  .done();

use Q-applied model methods:

var someModel = new SomeModel(...);
someModel.populateQ()
  .then(function (result) { ... })
  .catch(function (err) { ... })
  .done();

use Q-applied query methods:

SomeModel.find(...).where(...).skip(...).limit(...).sort(...).populate(...)
  .execQ() // no 'Q' suffix for model statics except for execQ()
  .then(function (result) { ... })
  .catch(function (err) { ... })
  .done();

use Q-applied aggregate methods:

SomeModel.aggregate(...).project(...).group(...).match(...).skip(...).limit(...).sort(...).unwind(...)
  .execQ() // no 'Q' suffix for model statics except for execQ()
  .then(function (result) { ... })
  .catch(function (err) { ... })
  .done();

to apply Q with custom suffix/prefix:

var mongoose = require('mongoose-q')(require('mongoose'), {prefix:'promiseOf_', suffix:'_withQ'});
SomeModel.promiseOf_findAndUpdate_withQ(...)
  .then(function (result) { ... })
  .catch(function (err) { ... })
  .done();

to apply Q with custom name mapper:

function customMapper(name) {
  return 'q' + name.charAt(0).toUpperCase() + name.substring(1);
}
var mongoose = require('mongoose-q')(require('mongoose'), {mapper:customMapper});
SomeModel.qFindAndUpdate(...)
  .then(function (result) { ... })
  .catch(function (err) { ... })
  .done();

to apply Q with spread:

var mongoose = require('mongoose-q')(require('mongoose'), {spread:true});
SomeModel.updateQ(...)
  .spread(function (affectedRows, raw) { ... })
  .catch(function (err) { ... })
  .done();
SomeModel.updateQ(...)
  .then(function (result) { var affectedRows = result[0], raw = result[1]; ... })
  .catch(function (err) { ... })
  .done();
...
var model = new SomeModel();
...
model.saveQ()
  .spread(function (savedDoc, affectedRows) { ... })
  .catch(function (err) { ... })
  .done();
...
model.saveQ()
  .then(function (result) { var savedDoc = result[0], affectedRows = result[1]; ... })
  .catch(function (err) { ... })
  .done();

NOTE: without spread option(by default), you can access only the first result with then!!

to define custom statics/instance methods using Q

SomeSchema.statics.findByName = function (name) {
  return this.findQ({name: name}); // NOTE: returns Promise object.
};
...
var SomeModel = mongoose.model('Some', SomeSchema);
SomeModel.findByName('foo').then(function(result) {
  console.log(result);
});

NOTE: this is not a feature of mongoose-q

That's all folks!
