collective.routes 1.1 Alpha 1

Ability to add route configuration for Plone
collective.routes is a product that provides routes implementation for Plone. What drives the route implementation is querying the portal catalog.

Example Route:

/posts/{effective:year}/{effective:month}/{effective:day}

To add a route:

from collective.routes import addRoute
addRoute('BlogItems',
 '/posts/{effective:year}/{effective:month}/{effective:day}',
 defaultQuery={'portal_type': 'News Item'})


Enable it

Before the route is usable, you need to first enable the route on the site you'd like to use it for. This can be done via the route configuration panel in Site Setup.

Out of the box routes

collective.routes has a couple example routes that it comes pre-packaged with.

blog posts

Blog Posts
 /posts/{effective:year}/{effective:month}/{effective:day}

Exmaple Urls:

/posts/2011 ~ Show all posts from 2011
/posts/2011/10 ~ Show all from 2011 and the month of October
/posts/2011/10/5 ~ Show the blog posted October 5, 2011


Definition:

addRoute('Blog Posts',
 '/posts/{effective:year}/{effective:month}/{effective:day}',
 defaultQuery={'portal_type': 'News Item',
 'sort_on': 'effective',
 'sort_order': 'reverse'})


tagged content

Tagged
 /tagged/{Subject}/{Subject}/{Subject}


Example Urls:

/tagged/foo ~ Show all posts tagged `foo`
/tagged/foo/bar ~ Show all posts tagged `foo` and `bar`
/tagged/foo/bar/woo ~ Show all posts tagged `foo`, `bar` and `woo`


Definition:

addRoute('Tagged',
 '/tagged/{Subject}/{Subject}/{Subject}',
 defaultQuery={'portal_type': 'News Item',
 'sort_on': 'effective',
 'sort_order': 'reverse'})


Route Syntax

The syntax is really basic and only has a few variations.

Literal

Literal string match:

/string-to-match

Will match "string-to-match"

Query

Match anything and maintain it as a query parameter:

/{Subject}

Will match any string and then keep the value as a query parameter to be used for a portal_catalog query.

Date Query

Has three sub-directives to match part parts:

/{effective:year}/{effective:month}/{effective:day}

Which will then put together a query for the portal_catalog to use.

Customize Object Retrieval

If you'd prefer to bypass the normal portal_catalog query to retrieve your object, you can provide your own object finder method.

Example:

def customObjectFinder(context, **kwargs):
 query = context.query
 site = getSite()
 return site[query['id']]

addRoute('My Route',
 '/my-route/{id}',
 objectFinder=customObjectFinder)


Fiddle with published object

If you'd like to be able to add interfaces at the last moment before the traversal is published, this is what you'd use.

This can be useful for adding interfaces since the actual published object is wrapped so breadcrumbs are maintained on publishing.

Example:

from interfaces import IMySpecialContext
from zope.interface import alsoProvides

def myMungeMethod(context):
 alsoProvides(context, IMySpecialContext)

addRoute('My Route',
 '/foo/{bar}',
 mungeObject=myMungeMethod)
