# Beanie
|
|
|
|
**FastAPI Users** provides the necessary tools to work with MongoDB databases using the [Beanie ODM](https://github.com/roman-right/beanie).
|
|
|
|
## Setup database connection and collection
|
|
|
|
The first thing to do is to create a MongoDB connection using [mongodb/motor](https://github.com/mongodb/motor) (automatically installed with Beanie).
|
|
|
|
```py hl_lines="5-9"
|
|
--8<-- "docs/src/db_beanie.py"
|
|
```
|
|
|
|
You can choose any name for the database.
|
|
|
|
## Create the User model
|
|
|
|
As for any Beanie ODM model, we'll create a `User` model.
|
|
|
|
```py hl_lines="12-13"
|
|
--8<-- "docs/src/db_beanie.py"
|
|
```
|
|
|
|
As you can see, **FastAPI Users** provides a base class that will include base fields for our `User` table. You can of course add you own fields there to fit to your needs!
|
|
|
|
!!! info
|
|
The base class is configured to automatically create a [unique index](https://roman-right.github.io/beanie/tutorial/defining-a-document/#indexes) on `id` and `email`.
|
|
|
|
## Create the database adapter
|
|
|
|
The database adapter of **FastAPI Users** makes the link between your database configuration and the users logic. It should be generated by a FastAPI dependency.
|
|
|
|
```py hl_lines="16-17"
|
|
--8<-- "docs/src/db_beanie.py"
|
|
```
|
|
|
|
Notice that we pass a reference to the `User` model we defined above.
|
|
|
|
## Initialize Beanie
|
|
|
|
When initializing your FastAPI app, it's important that you [**initialize Beanie**](https://roman-right.github.io/beanie/tutorial/initialization/) so it can discover your models. We can achieve this using a startup event handler on the FastAPI app:
|
|
|
|
```py
|
|
from beanie import init_beanie
|
|
|
|
|
|
@app.on_event("startup")
|
|
async def on_startup():
|
|
await init_beanie(
|
|
database=db, # (1)!
|
|
document_models=[
|
|
User, # (2)!
|
|
],
|
|
)
|
|
```
|
|
|
|
1. This is the `db` Motor database instance we defined above.
|
|
|
|
2. This is the Beanie `User` model we defined above. Don't forget to also add your very own models!
