Building the repository using Peewee

Among the different ORMs, Peewee is the simplest and smallest in terms of ORM features and APIs. The framework is easy to understand and use; it is not comprehensive, but it has intuitive ORM syntax. Its strength is in building and executing query transactions.

Peewee is not designed for asynchronous platforms, but it can work with them by using some async-related libraries that it supports. We need to install at least Python 3.7 for Peewee to work with FastAPI, an asynchronous framework. To install Peewee, we need to execute the following command:

pip install peewee

Installing the database driver

The ORM needs psycopg2 as the PostgreSQL database driver. We can install it using pip:

pip install psycopg2

Creating the database connection

For Peewee to work with FastAPI, we must build a multi-threading mechanism where Peewee can cater to more than one request transaction on the same thread, and per request can do more executions...
