Django-Access-Tastypie

The Django-Access-Tastypie package provides an authorization backend for the Django-Tastypie package to use access rules defined by the Django-Access package.

Installation

Stable version from the PyPi package repository

pip install django-access-tastypie

Last development version from the GitHub source version control system

pip install git+git://github.com/nnseva/django-access-tastypie.git

Configuration

Include the tastypie, access, and access_tastypie applications into the INSTALLED_APPS list, like:

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    ...
    'tastypie',
    'access',
    'access_tastypie',
    ...
]

Using

Define access rules

Define access rules as it is described in the Django-Access package documentation.

Modified model resource

You should use modified ModelResource successors in your project.

The access_tastypie.resources.AccessModelResourceMixin may be used to mix into any existent tastypie.resources.ModelResource successor.

The access_tastypie.resources.AccessModelResource may be used as a base class for your own model resource instead of tastypie.resources.ModelResource class. Really it is a pure combination of access_tastypie.resources.AccessModelResourceMixin andtastypie.resources.ModelResource base classes.

Authorization backend

You should use access_tastypie.authorization.AccessAuthorization authorization backend instead of tastypie.authorization.DjangoAuthorization. It will totally replace authorization algorithm to take access rules defined for your project in account while requesting your api.

Example

Having in mind the example defined for the Django-Access, let we describe the api resources as the following:

from tastypie.resources import ModelResource, ALL_WITH_RELATIONS
from tastypie.authentication import MultiAuthentication, SessionAuthentication

from access_tastypie.authorization import AccessAuthorization
from access_tastypie.resources import AccessModelResource

from django.contrib.auth import models as auth_models

class UserResource(AccessModelResource):
    class Meta:
        queryset = auth_models.User.objects.all()
        filtering = dict([(f.name, ALL_WITH_RELATIONS) for f in queryset.model._meta.get_fields()])
        authentication = MultiAuthentication(
            SessionAuthentication()
        )
        authorization = AccessAuthorization()
        resource_name = 'user'
        always_return_data = True
        excludes = ['password']

class GroupResource(AccessModelResource):
    class Meta:
        queryset = auth_models.Group.objects.all()
        filtering = dict([(f.name, ALL_WITH_RELATIONS) for f in queryset.model._meta.get_fields()])
        authentication = MultiAuthentication(
            SessionAuthentication()
        )
        authorization = AccessAuthorization()
        resource_name = 'group'
        always_return_data = True
