A lightweight REST miniframework for Python.
Documentation is at http://restless.readthedocs.org/.
Works great with Django, Flask, Pyramid, Tornado & Itty, but should be useful for many other Python web frameworks. Based on the lessons learned from Tastypie & other REST libraries.
- Small, fast codebase
- JSON output by default, but overridable
- RESTful
- Python 3.2+ (with shims to make broke-ass Python 2.6+ work)
- Flexible
(Things that will never be added...)
- Automatic ORM integration
- Authorization (per-object or not)
- Extensive filtering options
- XML output (though you can implement your own)
- Metaclasses
- Mixins
- HATEOAS
Quite simply, I care about creating flexible & RESTFul APIs. In building Tastypie, I tried to create something extremely complete & comprehensive. The result was writing a lot of hook methods (for easy extensibility) & a lot of (perceived) bloat, as I tried to accommodate for everything people might want/need in a flexible/overridable manner.
But in reality, all I really ever personally want are the RESTful verbs, JSON serialization & the ability of override behavior.
This one is written for me, but maybe it's useful to you.
Rather than try to build something that automatically does the typically correct thing within each of the views, it's up to you to implement the bodies of various HTTP methods.
Example code:
# posts/api.py
from django.contrib.auth.models import User
from restless.dj import DjangoResource
from restless.preparers import FieldsPreparer
from posts.models import Post
class PostResource(DjangoResource):
# Controls what data is included in the serialized output.
preparer = FieldsPreparer(fields={
'id': 'id',
'title': 'title',
'author': 'user.username',
'body': 'content',
'posted_on': 'posted_on',
})
# GET /
def list(self):
return Post.objects.all()
# GET /pk/
def detail(self, pk):
return Post.objects.get(id=pk)
# POST /
def create(self):
return Post.objects.create(
title=self.data['title'],
user=User.objects.get(username=self.data['author']),
content=self.data['body']
)
# PUT /pk/
def update(self, pk):
try:
post = Post.objects.get(id=pk)
except Post.DoesNotExist:
post = Post()
post.title = self.data['title']
post.user = User.objects.get(username=self.data['author'])
post.content = self.data['body']
post.save()
return post
# DELETE /pk/
def delete(self, pk):
Post.objects.get(id=pk).delete()
Hooking it up:
# api/urls.py
from django.conf.urls.default import url, include
from posts.api import PostResource
urlpatterns = [
# The usual suspects, then...
url(r'^api/posts/', include(PostResource.urls())),
]

The test suite uses tox for simultaneous support of multiple versions of both Python and Django. The current versions of Python supported are:
- CPython 2.7
- CPython 3.4
- CPython 3.5
- PyPy (Python 2.7)
- PyPy3 (Python 3.2)
- PyPy3 beta (Python 3.3)
You just need to install the Python interpreters above and the tox package (available via pip), then run the tox command.
