ripozo

Ripozo is a tool for building RESTful/HATEOAS/Hypermedia apis. It provides strong, simple, and fully qualified linking between resources, the ability to expose available actions and necessary parameters on a resource, and exposing multiple REST protocols (i.e. SIREN and HAL). Finally, ripozo is highly extensible. It is able to integrate with any web framework or database and you can easily roll out your own REST protocols.

Why use ripozo?

• Strong support for inter-resource linking (HATEOAS/Hypermedia)
• Flexible (can be used with any web framework, database, or response protocol)
• Fast development (especially when using the extensions, such as flask-ripozo or django-ripozo)
• Ability to expose actions on resource from the web api (self-discoverability)

Examples

You'll need to create a dispatcher using one of the dispatchers included in the framework extensions. You can find a list of framework extensions in The ripozo ecosystem section. If it's not there you can always roll out your own.

Minimal

from ripozo import apimethod, adapters, ResourceBase
# import the dispatcher class for your preferred webframework

class MyResource(ResourceBase):
    @apimethod(methods=['GET'])
    def say_hello(cls, request):
        return cls(properties=dict(hello='world'))

# initialize the dispatcher for your framework
# e.g. dispatcher = FlaskDispatcher(app)
dispatcher.register_adapters(adapters.SirenAdapter, adapters.HalAdapter)
dispatcher.register_resources(MyResource)

And just like that, you have an api that can return either Siren or Hal formatted responses. Pretty easy, right?

Full CRUD+L

On the other hand, if you wanted a full CRUD+L (Create, Retrieve, Update, Delete, and List), you could use one of the manager extensions (django-ripozo, ripozo-sqlalchemy, and ripozo-cassandra all include ready to use base managers). There are slight differences on creating Manager classes and instances in the different extensions but at a core they all follow this format.

from ripozo import restmixins
from fake_ripozo_extension import Manager
from myapp.models import MyModel # An ORM model for example a sqlalchemy or Django model.

class MyManager(Manager):
    fields = ('id', 'field1', 'field2',)
    model = MyModel

class MyResource(restmixins.CRUDL):
    manager = MyManager()
    pks = ('id',)

# Create your dispatcher and register the resource...

It is important to note that there are restmixins for each of the individual CRUD+L (i.e. restmixins.Create, restmixins.Retrieve, etc.) actions that can be mixed and matched to your pleasure.

Links

The coolest part of ripozo is the ability to easily create fully qualified links between resources.

from ripozo import restmixins, Relationship

class MyResource(restmixins.CRUDL):
    manager = MyManager()
    pks = ('id',)
    _relationships = [Relationship('related', relation='RelatedResource')]

class RelatedResource(restmixins.CRUDL)
    manager = RelatedManager()
    pks = ('id',)

Now whenever you request MyResource you'll get a link pointing to the related resource.

Versioning

Prior to version 1.0.0 ripozo versioning follows sentimental versioning. Releases after 1.0.0 follow a standard major.minor.patch style.

• patch: forwards and backwards compatible
• minor: backwards compatible
• major: No guarantees

Contributing

Want to help out? We'd love it! Github will be the hub of development for ripozo. If you have any issues, comments, or complaints post them there. Additionally, we are definitely accepting pull requests (hint: we almost always love more tests and documentation). We do have just a few requests:

• Every method, function, and class should have a thorough docstring
• There should be at least one unit test for each function and method
• Keep your pull requests to one issue. (Preferably open an issue on github first for record keeping)

Behind the name

Ripozo translates to "rest" in Esperanto. Esperanto was designed to be a universal language. Anyone, no matter their native language, can learn and use it easily. Similarly, ripozo is intended to be a universal ReST framework. No matter your preference of database, web framework, or protocol, ripozo makes it easy to build.
