getting schema attributes from Mongoose Model

Question

I\'m using Mongoose.js to create models with schemas.

I have a list of models (many) and at times I\'d like to get the attributes/keys that make up a particular mo

Answer 1

The accepted answer did not work for me. But using Mongoose 5.4.2 I was able to get the keys by doing the following:

const mySchema = new Schema({ ... });

const arrayOfKeys = Object.keys(mySchema.obj);

I'm using typescript, however. That might have been the problem.

Answer 2

My solution uses mongoose model.

Schema attributes

const schema = {
  email: {
    type: String,
    required: 'email is required',
  },
  password: {
    type: String,
    required: 'password is required',
  },
};

Schema

const FooSchema = new Schema(schema);

Model

const FooModel = model('Foo', FooSchema);

Get attributes from model:

Object.keys(FooModel.schema.tree)

Result:

[
  'email',
  'password',
  '_id',
  '__v'
]

If you want to have only the attributes you added and not the add methods by the ORM that starts with '$___', you have to turn the document into object then access the attributes like this:

Object.keys(document.toObject());
