Answer 1

It is possible, the quick way is:

you must have fastapi and django installed in the same environment.

The Django settins must be connected with your database and in fastAPI:

# main.py
import os
from fastapi import FastAPI
from your_django_project_name import settings as django_settings

os.environ['DJANGO_SETTINGS_MODULE'] = 'django_settings'
import django
django.setup()

app = FastAPI()

and after that, you have access:

from your_django_app_name.models import Blog

@app.get("/blogs/")
async def get_blogs():
    blogs = Blog.objects.all()
    return {"blogs": [blog.title for blog in blogs]}

To ensure the conection you must create a FastAPI Middleware

from fastapi.middleware.base import BaseHTTPMiddleware
from django import db

class DBConnectionMiddleware(BaseHTTPMiddleware):
    async def dispatch(self, request, call_next):
        db.connections["default"].ensure_connection()
        response = await call_next(request)
        db.connections["default"].close()
        return response

app.add_middleware(DBConnectionMiddleware)
