Resource baseclasses for traversal in Pyramid

Project description

Kalpa provides a starting point for resource traversal in Pyramid. It provides two classes for this, a Branch and a Leaf, which allow you to create arbitrary resource trees without the boilerplate.

There is also a Root class for added convenience that accepts a request during initialization. This can be used to create a starting point for Pyramid’s traversal.

from kalpa import Root, Branch, Leaf

USERS = {...}


@Root.attach('users')
class UserCollection(Branch):
    """User collection, for listings, or loading single users."""

    def __load__(self, key):
        """Return child resource with requested user included."""
        user = USERS[key]  # Load user or raise KeyError.
        return self._child(key, user=user)


@UserCollection.child_resource
class User(Branch):
    """User resource, a single loaded user."""


@User.attach('gallery', aliases=['images'])
class UserGallery(Leaf):
    """Gallery of images posted by a user.

    Reachable as `/users/:id/gallery` but also `/users/:id/images`.
    """
