=============
genericclient
=============

A generic client for RESTful APIs

::

$ pip install genericclient


Quickstart
==========

::

from genericclient import GenericClient

myclient = GenericClient(api_url)

myresource = myclient.resources.get(id=1)

actives = myclient.posts.filter(active=True)


Usage
=====

Instantiation
-------------

::

myclient = GenericClient(url, auth=None, adapter=None, trailing_slash=False)


Arguments:

* ``url``: The root URL of your API
* ``auth``: The auth for your API. You can pass anything that ``requests`` can accept as auth.
* ``adapter``: optional session adapter for ``requests``.
* ``trailing_slash``: You can set this to ``True`` if your API's URLs end with a ``/``

Endpoints
---------

Endpoints are available as properties on the main instance.

``.all()``
~~~~~~~~~~

Retrieves all resources (essentially a simple ``GET`` on the endpoint)::

myclient.posts.all() # GET /posts/

``.filter(**kwargs)`` calls a ``GET`` with ``kwargs`` as querystring values::

myclient.posts.filter(blog=12, status=1) # GET /posts/?blog=12&status=1

``.get(**kwargs)``
~~~~~~~~~~~~~~~~~~

A special case of ``.filter()``.

If ``kwargs`` contains ``id``, ``pk``, ``slug`` or ``username``, that value will
be used in the URL path, in that order.

Otherwise, it calls a ``GET`` with ``kwargs`` as querystring values.

If the returned list is empty, will raise ``ResourceNotFound``.

If the returned list contains more than 1 resource, will raise ``MultipleResourcesFound``

Note that ``.get()`` will return a ``Resource``, not a list of ``Resource``s

::

myclient.posts.filter(blog=12, status=1) # GET /posts/?blog=12&status=1
myclient.posts.filter(id=12) # GET /posts/12/
myclient.posts.filter(slug='12-ways-clickbait') # GET /posts/12-ways-clickbait/

``.create(payload)``
~~~~~~~~~~~~~~~~~~~~

Will result in a ``POST``, with ``payload`` (a ``dict``) as the request's body,
returning a new ``Resource``::

post = myclient.posts.create({'blog': 12, 'status': 1}) # POST /posts/

``.create_or_update(payload)``
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

If ``payload`` contains a key called ``'id'``, will issue a ``PUT``, otherwise
it will call ``.create``::

post = myclient.posts.create_or_update({'id': 1234, 'status': 1}) # PUT /posts/1234/


``.delete(pk)``
~~~~~~~~~~~~~~~

Will issue a ``DELETE``, and will use ``pk`` as part of the URL::

myclient.posts.delete(24) # DELETE /posts/24/

Resources
---------

All endpoints methods (with the exception of ``.delete()``) return either a
``Resource`` or a list of ``Resource``s.

A ``Resource`` is just a wrapping class for a ``dict``, where keys can be accessed
as properties.

Additionally, ``Resource`` s have a special property called ``.payload``, which
contains the original payload received from the server.

``Resource``s have the following methods:

``Resource.delete()`` will result in a ``DELETE``, with ``Resource.id`` as
par of the URL::

blog = myclient.posts.create({'blog': 12, 'status': 1}) # POST /posts/
blog.delete() # DELETE /blog/345/ -- the ID 345 was returned by the server in the previous response

``Resource.save()`` will result in a ``PUT``, with ``Resource.id`` as
par of the URL::

post = myclient.posts.create({'blog': 12, 'status': 1}) # POST /posts/
post.status = 2
post.save() # PUT /posts/345/
