Mongoose: what's up with “_doc”?

Question

It seems Mongoose is doing something really funky internally.

1 var Foo = new mongoose.model(\'Foo\', new mongoose.Schema({a: String, b: Number}));
2 var foo

There is some weirdness with Mongoose models and you have to check that Mongoose doesn't already have a model created in it's models array.

Here is my solution:

import mongoose from 'mongoose';
createModel = (modelName="foo", schemaDef, schemaOptions = {})=> {
  const { Schema } = mongoose;
  const schema = Schema(schemaDef, schemaOptions);
  const Model = mongoose.models[modelName] || mongoose.model(modelName, schema);
  return Model;
}

I use my own mongoose model class and base class for my models. I made this and it should work for you.
