ohmyapi 0.1.1

A Django-like but async web-framework based on FastAPI and TortoiseORM.

OhMyAPI

OhMyAPI == Application scaffolding for FastAPI+TortoiseORM.

OhMyAPI is a blazingly fast, async Python web application framework with batteries included. It is built around FastAPI and TortoiseORM and is thus 100% async.

Features:

• Django-like project-layout and -structure
• Django-like settings.py
• Django-like models via TortoiseORM
• Django-like model.Meta class for model configuration
• Django-like advanced permissions system
• Django-like migrations (makemigrations & migrate) via Aerich
• Django-like CLI for interfacing with your projects (startproject, startapp, shell, serve, etc)
• various optional builtin apps
• highly configurable and customizable
• 100% async

Getting started

Creating a Project

pip install ohmyapi  # TODO: not yet published
ohmyapi startproject myproject
cd myproject

This will create the following directory structure:

myproject/
  - pyproject.toml
  - settings.py

Run your project with:

ohmyapi serve

In your browser go to:

• http://localhost:8000/docs

Creating an App

Create a new app by:

ohmyapi startapp myapp

This will lead to the following directory structure:

myproject/
  - myapp/
    - __init__.py
    - models.py
    - routes.py
  - pyproject.toml
  - settings.py

Add 'myapp' to your INSTALLED_APPS in settings.py.

Write your first model in myapp/models.py:

from ohmyapi.db import Model, field


class Person(Model):
    id: int = field.IntField(min=1, pk=True)
    name: str = field.CharField(min_length=1, max_length=255)
    username: str = field.CharField(min_length=1, max_length=255, unique=True)
    age: int = field.IntField(min=0)

Next, create your endpoints in myapp/routes.py:

from fastapi import APIRouter, HTTPException
from tortoise.exceptions import DoesNotExist

from .models import Person

router = APIRouter(prefix="/myapp")


@router.get("/")
async def list():
    return await Person.all()


@router.get("/:id")
async def get(id: int):
    try:
        await Person.get(pk=id)
    except DoesNotExist:
        raise HTTPException(status_code=404, detail="item not found")

...

Migrations

Before we can run the app, we need to create and initialize the database.

Similar to Django, first run:

ohmyapi makemigrations [ <app> ]  # no app means all INSTALLED_APPS

This will create a migrations/ folder in you project root.

myproject/
  - myapp/
    - __init__.py
    - models.py
    - routes.py
  - migrations/
    - myapp/
  - pyproject.toml
  - settings.py

Apply your migrations via:

ohmyapi migrate [ <app> ]  # no app means all INSTALLED_APPS

Run your project:

ohmyapi serve

Shell

Similar to Django, you can attach to an interactive shell with your project already loaded inside.

ohmyapi shell

Authentication

A builtin auth app is available.

Simply add ohmyapi_auth to your INSTALLED_APPS and define a JWT_SECRET in your settings.py. Remember to makemigrations and migrate for the auth tables to be created in the database.

settings.py:

INSTALLED_APPS = [
    'ohmyapi_auth',
    ...
]

JWT_SECRET = "t0ps3cr3t"
