infrae.rest 1.3

Define a REST API to access and manage Zope 2 content

infrae.rest provide a simple way to write REST APIs in Zope 2.

API

REST component

infrae.rest provides mainly a base class REST which behave a lot like a Grok view:

from infrae.rest import REST

class MyAction(REST):
    """My action REST API.
    """

    def POST(self, name, value):
        # Called by POST /content/++rest++myaction&name=foo?value=bar
        return 'Success'

    def GET(self):
        # Called by GET /content/++rest++myaction
        values = self.context.something()
        return self.json_response(values)

You just have to grok your package to make it available.

• You can provide: POST, GET, HEAD, DELETE requests.

• You can use the directives grok.name, grok.require and grok.context to configure your REST API. They work exactly like on a grok.View.

• If you need, you can manually query a REST component with the help of infrae.rest.queryRESTComponent.

Nesting REST component

You can nest REST component. In that you should use the grok directive adapts in order to define which is the parent handler, and the context:

from infrae.rest import REST
from five import grok
from OFS.Folder import Folder

class ParentHandler(REST):
    grok.context(Folder)

    def GET(self):
        # Called by GET /folder/++rest++parenthandler
        return u'Hello'


class ChildHandler(REST):
    grok.adapts(ParentHandler, Folder)

    def GET(self):
        # Called by GET /folder/++rest++parenthandler/childhandler
        return u'Child

RESTWithTemplate component

You can alternatively use the base class RESTWithTemplate. The only difference is that your class will be associated to a Grok template automatically.

Changes

1.3 (2013-05-23)

• Add support for static on a RESTWithTemplate component.

• Update tests.

1.2 (2012-09-04)

• Change registry for handlers from zope.component to zeam.component. This simplify the code base and brings more flexibility. Expose queryRESTComponent function.

• Remove usage of Zope 2 shiftNameToApplication, as this is buggy in recent Zope 2 releases.

1.1 (2011-11-07)

• Add support for nested handlers.

• Add support for absoluteURL, in order to get back the URL of an handler.

• Add a default component that is associated with a Grok template. You have to trigger the template rendering yourself.

• An event is triggered when a handler is published. If the handlers are nested, the event is only triggered for the last one. You can see as publisher after traverse event, except you have access to the associated handler that is published.

• We now use only the Python native json module (and no longer simplejson).

1.0.1 (2010-10-07)

• Don’t define response as a property to be compatible with other Zope views (as a mixin).

1.0 (2010-07-15)

• Initial release
