Installation

Requirements

• Python >= 2.6, < 3.0

• Requests >= 1.2.3

Usage

Lets work through an example. The code for this example is in example.py.

• First you import wac:

import wac

• Next define the version of your client:

__version__ = '1.0'

• Also define the configuration which all Clients will use by default:

default_config = wac.Config(None)

• Now be nice and define a function for updating the configuration(s):

def configure(root_url, **kwargs):
    default = kwargs.pop('default', True)
    kwargs['client_agent'] = 'example-client/' + __version__
    if 'headers' not in kwargs:
        kwargs['headers'] = {}
    kwargs['headers']['Accept-Type'] = 'application/json'
    if default:
        default_config.reset(root_url, **kwargs)
    else:
        Client.config = wac.Config(root_url, **kwargs

• Now the big one, define your Client which is what will be used to talk to a server:

class Client(wac.Client):

    config = default_config

    def _serialize(self, data):
        data = json.dumps(data, default=self._default_serialize)
        return 'application/json', data

    def _deserialize(self, response):
        if response.headers['Content-Type'] != 'application/json':
            raise Exception(
                "Unsupported content-type '{}'"
                .format(response.headers['Content-Type'])
            )
        data = json.loads(response.content)
        return data

• Then define your base Resource:

class Resource(wac.Resource):

    client = Client()
    registry = wac.ResourceRegistry()

• And finally your actual resources:

class Playlist(Resource):

    type = 'playlist'

    uri_gen = wac.URIGen('/v1/playlists', '{playlist}')


class Song(Resource):

    type = 'song'

    uri_gen = wac.URIGen('/v1/songs', '{song}')

• Done! Now you can do crazy stuff like this:

import example

example.configure('https://api.example.com', auth=('user', 'passwd'))

q = (example.Playlist.query()
    .filter(Playlist.f.tags.contains('nuti'))
    .filter(~Playlist.f.tags.contains('sober'))
    .sort(Playlist.f.created_at.desc()))
for playlist in q:
    song = playlist.songs.create(
        name='Flutes',
        length=1234,
        tags=['nuti', 'fluti'])
    song.length += 101
    song.save()
