 Express-mongoose adds Mongoose Query and Promise support to Express render, partial, and send methods.

## Installation

    $ npm install express-mongoose

### Example

  In your models:

    User.methods.getLikes = function (callback) {
      // returns a Query
      return this.model('Likes').find({ _user: this._id }, callback);
    };

    News.statics.getLatest = function (callback) {
      var promise = new Promise;
      if (callback) promise.addBack(callback);
      this.find({ datePublished: { $gt: new Date(Date.now() - 60000*60) } }, promise.resolve.bind(promise));
      return promise;
    };

  In your routes:

    app.get('/dashboard', function (req, res) {
      var News = db.model('News');

      // render support
      res.render('dashboard', {
          likes: req.user.getLikes()
        , latestNews: News.getLatest()
        , locals: {
            backwardcompatible: new Promise(somethingAsync)
          }
      });
    });

    app.get('/partial', function (req, res, next) {
      res.partial('likes', {
          likes: req.user.getLikes()
        , locals: {
            backwardcompatible: new Promise(somethingAsync)
          }
      });
    });

  Just pass a Query or Promise in and the result will be rendered as json.
  If an error occurs, the error will be next()ed along as expected.

    app.get('/send', function (req, res) {
      var News = db.model('News');
      res.send(News.getLatest());
    });

    app.get('/promises', function (req, res) {
      var promise = new Promise(somethingAsync);
      res.send(promise);
    });

    app.get('/more', function (req, res) {
      res.send({
          promise: new Promise(somethingAsync)
        , news: req.user.getLatest()
      });
    });

### Features

 - res.render support
 - res.partial support
 - res.send support
 - nested express locals support

### Error handling

 If a Query or Promise resolves to an error it will be forwarded on with `next(err)` as expected.
