[FIXED] Is it possible to use FastAPI with Django?

Issue

I'm a Django developer and recently stumbled onto the FastAPI framework.

Then I decided to give it a shot. But usually when you talk about building RESTful APIs with Django you usually use the Django Rest Framework (DRF).

Is anybody aware if it is possible to substitute DRF by FastAPI using Django perks, like its ORM, and still have access to all of FastAPI's async features?

Up until now I only found one article on this. But in the process of integration the author lost most of the features of FastAPI. You can find it here.

In the FastAPI docs, they do mention that it is possible to redirect certain request to a WSGI application here.

Solution

Short Answer

Yes it's possible with WSGIMiddleware.

For example, you can use all Django features (yes admin too) with mounting, with this example code.

import os
from importlib.util import find_spec

from configurations.wsgi import get_wsgi_application
from fastapi import FastAPI
from fastapi.middleware.wsgi import WSGIMiddleware
from fastapi.staticfiles import StaticFiles

from api import router

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "myapp.settings")
os.environ.setdefault("DJANGO_CONFIGURATIN", "Localdev")

application = get_wsgi_application()

app = FastAPI()
app.mount("/admin", WSGIMiddleware(application))
app.mount("/static"
    StaticFiles(
         directory=os.path.normpath(
              os.path.join(find_spec("django.contrib.admin").origin, "..", "static")
         )
   ),
   name="static",
)

Also this one is from WSGIMiddleware documentation, it's a more straight-forward example (This one is for Flask but it demonstrates the same idea.).

from fastapi import FastAPI
from fastapi.middleware.wsgi import WSGIMiddleware
from flask import Flask, escape, request

flask_app = Flask(__name__)


@flask_app.route("/")
def flask_main():
    name = request.args.get("name", "World")
    return f"Hello, {escape(name)} from Flask!"


app = FastAPI()


@app.get("/v2")
def read_main():
    return {"message": "Hello World"}


app.mount("/v1", WSGIMiddleware(flask_app))
