[Django]-How can I use the Django ORM in my Tornado application?


Add the path to the Django project to the Tornado application’s PYTHONPATH env-var and set DJANGO_SETTINGS_MODULE appropriately. You should then be able to import your models and use then as normal with Django taking care of initial setup on the first import.

You shouldn’t require any symlinks.



there is an example here about how to use django ORM and django form inside Tornado.
and you can read Using Django Inside the Tornado Web Server for some information. the following code has taken from there:

import sys
import os

import tornado.httpserver
import tornado.ioloop
import tornado.web

# django settings must be called before importing models
from django.conf import settings
settings.configure(DATABASE_ENGINE='sqlite3', DATABASE_NAME='dev.db')

from django import forms
from django.db import models

# Define your Model
class Message(models.Model):
    A Django model class.
    In order to use it you will need to create the database manually.

    sqlite> CREATE TABLE message (id integer primary key, subject varchar(30), content varchar(250));
    sqlite> insert into message values(1, 'subject', 'cool stuff');
    sqlite> SELECT * from message;

    subject = models.CharField(max_length=30)
    content = models.TextField(max_length=250)
    class Meta:
        app_label = 'dj'
        db_table = 'message'
    def __unicode__(self):
        return self.subject + "--" + self.content

# Define your Form
class DjForm(forms.Form):
    subject = forms.CharField(max_length=100, required=True)
    content = forms.CharField()

# Define the class that will respond to the URL
class ListMessagesHandler(tornado.web.RequestHandler):
    def get(self):
        messages = Message.objects.all()
        self.render("templates/index.html", title="My title",

class FormHandler(tornado.web.RequestHandler):
    def get(self):
        form = DjForm()
        self.render("templates/form.html", title="My title", form=form)

    def post(self):
        data = {
        form = DjForm(data=data)
        if form.is_valid():
            message = Message(**form.cleaned_data)
            self.render("templates/form.html", title="My title", form=form)

# map the Urls to the class          
application = tornado.web.Application([
    (r"/", ListMessagesHandler),
    (r"/form/", FormHandler),

# Start the server
if __name__ == "__main__":
    http_server = tornado.httpserver.HTTPServer(application)

and this is another demo with django and tornado…



I could not get it to work with the information provided by @aragon in Django 1.8. Since this question is one of the top results in Google when searching for Django + Tornado integration, here is how I got it to work in Django 1.8:

from django import forms
from django.db import models

from models import Operation #Own model
import django

'default': {
    'ENGINE': 'django.db.backends.sqlite3',
    'NAME': 'database.db',

if django.VERSION[:2] > (1,5):
