Setting up MongoDB

There are a number of libraries that allow us to integrate MongoDB into our FastAPI application. However, we’ll be using Beanie, an asynchronous Object Document Mapper (ODM) library, to execute database operations from our application.

Let’s install the beanie library by running the following command:

(venv)$ pip install beanie

Before diving into the integration, let’s look at some of the methods from the Beanie library and also how database tables are created in this section.

Documents are defined the same way a Pydantic model is defined, except that the Document class from the Beanie library is inherited instead.

An example document is defined as follows:

from beanie import Document
class Event(Document):
