Is there a way to get the model name from a mongoose model instance?

Question

I´m using mongoose and I need to find a model name from a model instance.

In one part of the code I have:

 const schema = new mongoose.Schema({
        name: {
            type: String,
            required: true
        },
        phone: {
            type: String,
            required: true
        }
    }

const schema = new mongoose.Schema('MyData', schema);

let instance = new this({
      name: 'Pete',
      phone: '123'
});

Ths instance variable is passed around in my code. Later I need to find out instance name, but I´m no sure if there is a way to do it, something like:

let instanceName = getInstanceName(instance); <== Expects 'MyData' to be returned

Is that possible using mongoose ?

Answer 1

I realized I had a model not an instance of a model so I needed to use something else.

If you have a model, you can get the name as below:

const model = mongoose.model("TestModel", schema);
const collectionName = model.collection.collectionName;

If you have a specific item/instance of the model:

const instance = new model({...});
const collectionName = instance.constructor.modelName

as Hannah posted.

Answer 2

The name of the model can be accessed using this instance.constructor.modelName.
