mongoose statics `this` is not a model reference

See original GitHub issue

I am using mongoose v4.5.3

I am having trouble with mongoose statics function. this keyword inside a static function should refer to the model (so that we can use .find and other query) but in my case this is completely different. Hence this.find is showing undefined.

this is below

and error is

TypeError: model.findOne is not a function

static function is

authorSchema.statics.authenticate = function(req, res, next){
    var model = this;
    console.log(this);
    var authToken = req.get('x-auth-token');

    if(!authToken){
        return res.sendStatus(401);
    }

    model
    .findOne({authToken : authToken}, function(err, doc){
        if(err)             return res.sendStatus(500);
        if(_.isEmpty(doc))  return res.sendStatus(403);
                            return next();
    });

}

I am using it as a express middleware

Models = require(_dir + '/_mongoose/Models')
Router.put('/', Models.Author.authenticate, function(req, res){
    res.send("You are allowed!");
});

I wouldn’t recommend using mongoose functions as express middleware directly, trying to get 2 different abstractions to play nicely together is pretty difficult, I’d recommend just doing something like:

Router.put('/', function(req, res, next) { Models.Author.authenticate.then(next, next); }, function(req, res){
    res.send("You are allowed!");
});

Models = require(_dir + '/_mongoose/Models')
Router.put('/', Models.Author.authenticate.bind(Models.Author), function(req, res){
    res.send("You are allowed!");
});
