TastyTopping 1.2.5

An ORM for tastypie's API on the client-side.

Designed to take the heavy lifting out of working with django-tastypie APIs on the client side.

Features

• Django model-like ORM API allowing you to GET, POST, PUT, PATCH, and DELETE:

  factory = ResourceFactory('http://localhost:8000/myapp/api/v1/')
  current_resource = factory.resource.get(field='name')    # GET
  new_resource = factory.resource(field='new_name').save() # POST
  new_resource.field = 'different_name'
  new_resource.save()                                      # PUT / PATCH
  current_resource.delete()                                # DELETE

• Easily work with any related resources:

  new_resource.children = [
      factory.resource(field='new_name1').save(),
      factory.resource(field='new_name2').save(),
  ]

• QuerySets:

  queryset1 = factory.resource.filter(field2__gt=20)
  queryset2 = queryset1.order_by('field2')
  # Evaluation happens here:
  resources = queryset2[5:-8]

• Simple way to set and update authentication per resource:

  factory.resource.auth = HTTPApiKeyAuth('username', 'key12345')

• Access nested resources using simple methods:

  new_resource.nested.nested_resource('arg1', arg2=3)

• Basic field validation before connecting to the API.

• Bulk create / update / delete to minimise API access:

  factory.resource.bulk(
      create=[{field='name1'}, {field='name2'}],
      update=[current_resource, new_resource],
      delete=[new_resource],
  )

Requirements

The following needs to be installed locally to run TastyTopping:

• Python 2.7+ or Python 3.3+

• requests >= 1.2.3

Tested with / against:

• django >= 1.5.0

• django-tastypie >= 0.9.14

• requests >= 1.2.3

(see the tox.ini file for more information).

Example

A basic example of a simple workflow, using the following API on the server side:

# myapp/models.py
# ===============
from django.db import models

class Example(models.Model):
    path   = models.CharField(max_length=255, unique=True)
    rating = models.IntegerField(default=50)
    date   = models.DateTimeField('date', null=True)


# myapp/api.py
# ============
from .models import Example

class ExampleResource(ModelResource):
    class Meta:
        queryset = Example.objects.all()
        resource_name = 'example'
        authorization = Authorization()
        filtering = {'path': ALL, 'rating': ALL}
        ordering = ['rating']

Using TastyTopping on the client side would look like this:

from datetime import datetime
from tastytopping import ResourceFactory

factory = ResourceFactory('http://localhost:8000/myapp/api/v1/')
ex1 = factory.example(path='any text', rating=80).save()
ex1.date = datetime.now()
ex1_copy = factory.example.get(rating=80)
ex1.delete()

Justification

Why another one? There are some other packages around that do something similar, but none are the complete package:

• ORM. A lot of other packages use a C-style API, which involves passing a dict with your data to their functions. TastyTopping wraps it all up in an ORM-style object, which is more OO, more elegant, and more pythonic.

• Python3 support.

• Support for authentication.

• Support for nested resources.

• QuerySets!

• A thorough set of unit tests.

• Development has stagnated (none of them have released in close to a year, whereas tastypie has been releasing thick and fast).

• Creating this was FUN!
