MongoDB

FastAPI Users provides the necessary tools to work with MongoDB databases thanks to mongodb/motor package for full async support.

Setup database connection and collection

Let's create a MongoDB connection and instantiate a collection.

{!./src/db_mongodb.py!}

You can choose any name for the database and the collection.

Create the database adapter

The database adapter of FastAPI Users makes the link between your database configuration and the users logic. Create it like this.

{!./src/db_mongodb.py!}

!!! info The database adapter will automatically create a unique index on id and email.

!!! warning FastAPI Users will use its defined id UUID-string as unique identifier for the user, rather than the builtin MongoDB _id.

Next steps

We will now configure an authentication method.
