Mongoose discriminators, instantiate documents
A better implementation should be to use an object instead of a switch.
var modelMap = { 'GenericEvent': GenericEventModel, 'ClickedLinkEvent': ClickedLinkEventModel, 'SignedUpEvent': SignedUpEventModel};function getMongooseModel(type) { return modelList[type];}After that in order to avoid errors you can use Mongoose#plugin(fn, [opts]) in order to populate the modelMap object.
Or you can just use Mongoose#model(name, [schema], [collection], [skipInit]).
Defines a model or retrieves it.
Something like this should work:
module.exports.createEvent = function(req, res, next) { var Model = mongoose.model(req.params.type); (new Model(req.body)).save(next);}With a proper declaration of your model class in mongoose, model name must match your request parameter of course.
var GenericEventModel = mongoose.model('GenericEvent', GenericEventModelSchema);
