Lastest release
dj-webmachine is an application layer that adds HTTP semantic awareness on top of Django and provides a simple and clean way to connect that to your applications' behavior. dj-webmachine also offers you the possibility to build simple API based on your model and the tools to create automatically docs and clients from it (work in progress).
Install
Make sure that you have a working Python 2.x >=2.5 installed and Django >= 1.1.
With pip
$ pip install dj-webmachine
From source
Get the dj-webmachine code:
$ git clone https://github.com/benoitc/dj-webmachine.git $ cd dj-webmachine
Or using a tarbal:
$ wget http://github.com/benoitc/dj-webmachine/tarball/master -o dj-webmachine.tar.gz $ tar xvzf dj-webmachine.tar.gz $ cd dj-webmachine-$HASH/
and install:
$ sudo python setup.py install
dj-webmachine in 5 minutes
We will quickly create an Hello world accepting HTML and JSON.
$ django-admin startproject helloworld $ cd helloworld $ python manage.py startapp hello
In the hello folder create a file named resources.py:
import json
from webmachine import Resource
class Hello(Resource):
def content_types_provided(self, req, resp):
"""" define the content type we render accoridng the Accept
header.
"""
return (
("", self.to_html),
("application/json", self.to_json)
)
def to_html(self, req, resp):
return "<html><body>Hello world!</body></html>\n"
def to_json(self, req, resp):
return "%s\n" % json.dumps({"message": "hello world!", "ok": True})
Add dj-webmachine and your hello app to INSTALLED_APPS in your settings:
INSTALLED_APPS = (
...
'webmachine',
'helloworld.hello'
)
Put your the Hello resource in your urls.py:
from django.conf.urls.defaults import *
from helloworld.hello.resource import Hello
urlpatterns = patterns('',
(r'^$', Hello()),
)
Launch your application:
$ python manage.py runserver
Take a look! Point a web browser at http://localhost:8000/
Or with curl:
$ curl http://127.0.0.1:8000
<html><body>Hello world!</body></html>
$ curl http://127.0.0.1:8000 -H "Accept: application/json"
{"message": "hello world!", "ok": true}
The first line ask the hello page as html while the second using the same url ask for JSON.
