MongoDB: Create Mongoose Model / Schema from document stored in MongoDB - json

Question

As the title describes, I am trying to find out if I can instantiate a new mongoose model and schema with the JSON of a existing MongoDB document? It seems like I could do it as long as I have retrieve the document before Mongoose runs.
Is this possible? Ideally I would like to do it on the fly where I do NOT need to restart node.
**** Edit ****** Here is what I have tried.
note: the setTimeout is in there incase the schema creation is async. This is a down and dirty mockup just to see if this concept works. :).
THIS Does NOT Work!!!
function initModels(models) {
for (var i = 0, l = models.length; i < l; i++) {
console.log(models[i])
exports[models[i].name + "Schema"] = mongoose.Schema(models[i].model, {collection: "ModelData"});
(function(itrModel){
var model = itrModel;
setTimeout(function(){
exports[model.name] = mongoose.model(model.name.toUpperCase(), model.name + "Schema");
},2000)
})(models[i])
}
}
exports.getModels = function () {
DataConnection.Connect(function (db) {
var collectionName = "Models";
var collection = db.collection(collectionName);
collection.find().toArray(function (err, models) {
initModels(models);
})
})
};
Here is the model that is stored in the db
{
"name" : {
"type" : "String",
"required" : true
},
"email" : {
"type" : "String",
"required" : false,
"index" : true,
"index" : true
},
"password" : {
"type" : "String",
"required" : true
},
"role" : {
"type" : "String",
"required" : true
},
"createDate" : {
"type" : "Number",
"required" : true
}
}
