Anti-Features

Things that will never be added to the core library - but plugins are encouraged!

• Authorization (per-object or not)

• Extensive filtering options

• XML output

• Metaclasses

• Mixins

• HATEOAS

Why?

Creator @toastdriven had a very specific goal when building the original restless, and our goal is to respect it. Here it follows:

> 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.

Manifesto

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 restkiss.dj import DjangoResource
from restkiss.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())),
]

Running the Tests

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.
