collective.routes 1.1a1

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.

/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

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

/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`

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

Route Syntax

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

/string-to-match

/{Subject}

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

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)

Customize view rendered

You can customize the view that is rendered for the found object also:

addRoute('My Route',
     '/foo/{bar}',
     customViewName='@@custom-view')

addRoute Signature

Allow arguments

routeName(required)

Name of route

route(required)

Actual route specification

defaultQuery(defaults to {})

Default query to provide the finder with

objectFinder(defaults to collective.routes.finders.catalogObjectFinder)

The method used to find the result published object

mungeObject(defaults to None)

Since the real published is a wrapper object, this is a method to be able to mess with the temporary wrapper object before publication

customViewName(defaults to None)

Custom view to render for the found object

allowPartialMatch(defaults to False)

If the whole url is not matched, you can still attempt to publish it. This can be useful for catalog finder routes where you want to allow the user to provide partial urls and still find objects.

breadcrumbFactory(defaults to None)

Override breadcrumb generation. Must return a tuple of {‘absolute_url’: url, ‘Title’: title} values.

customPredicates(defaults to [])

An iterable of custom predicate functions(s) to check against the incoming request that they match. A predicate must take 2 parameters(request, query) where request is the current request object and query is the currently generated query from the route. The function must return a boolean. True if it matches, False it doesn’t.
