A set of songs or List of songs

Question

I have attached a user schema (see below)

I would like to save a list of tunes for each user

How to do it?

For example

For email I used the EmailStr type

What to add in this line of code

Tune: Indexed()

from uuid import UUID, uuid4
from beanie import Document, Indexed
from pydantic import Field, EmailStr 



class User(Document):
    user_id: UUID = Field(default_factory=uuid4)
    username: Indexed(str, unique=True)
    email: Indexed(EmailStr, unique=True)
    hashed_password: str
    Tune: Indexed()
