mongoose.connection.model return instanceof Model

I could not find a way to test the return from mongoose.connection.model against any Model "class" i could find, it would always return false, so i wanted to ask if there is a way to match this model type against any model class? (because Connection.prototype.Model does not exist)

example:

const model = mongoose.connection.model('test', new mongoose.Schema());

console.log(model instanceof mongoose.Model); // false
console.log(model instanceof mongoose.connection.Model); // this property does not exist
console.log(model instanceof mongoose.connection.base.Model); // false

mongoose.connection.model returns a "class" that extends from mongoose.Model, not an instance of mongoose.Model. console.log(Object.getPrototypeOf(model) === mongoose.Model); // true

[hasezoey]

"class" that extends

with the normal interpretation of that, shouldnt it then still be a instance of the model class if it just "extends" it?

like normal js

class A {}
class B extends A {}

console.log(new B() instanceof A); // true

Yeah, if you do const TestModel = mongoose.connection.model('Test', schema); const doc = new TestModel(); doc instanceof mongoose.Model; // true

thanks, forgot again that a document is a instance of Model and not model(compiled from schema) a instance of Model(statically provided by mongoose)
or said in different terms, i forgot that the models returned by .model are extensions of Model and documents are instances of the models
