Insert the documents

Beanie documents behave just like pydantic models (because they are pydantic models). Hence a document can be created in a similar fashion to pydantic:

from typing import Optional
from pydantic import BaseModel
from beanie import Document, Indexed

class Category(BaseModel):
    name: str
    description: str

class Product(Document):  # This is the model
    name: str
    description: Optional[str] = None
    price: Indexed(float)
    category: Category

    class Settings:
        name = "products"

chocolate = Category(name="Chocolate", description="A preparation of roasted and ground cacao seeds.")
tonybar = Product(name="Tony's", price=5.95, category=chocolate)
marsbar = Product(name="Mars", price=1, category=chocolate)

This however does not save the documents to the database yet.

Insert a single document

To insert a document into the database, you can call either insert() or create() on it, they are synonyms:

await tonybar.insert()
await marsbar.create() # does exactly the same as insert()

You can also call save(), which behaves the same for new documents, but will also update existing documents. See the section on updating of this tutorial for more details.

If you prefer you can also call the insert_one classmethod:

await Product.insert_one(tonybar)

Inserting many documents

To reduce the number of database queries, similarly typed documents should be inserted together by calling the classmethod insert_many.

await Product.insert_many([tonybar,marsbar])
