As new projects started to use ACR to implement the content management part of the site we started to divide the ACR application from the content management framework to permit to other people to embed the cmf inside their own applications. Now has been divided in libACR which is the content management framework and ACRcms which is the cms application. This should make easier to use libACR to implement your own CMS or extend your web applications and also fast for anyone who needs a quickly available CMS solution to just use ACRcms and tune the graphic theme and layout.

All you need is those three little things: from pylons.decorators.cache import beaker_cache from pylons.controllers.util import etag_cache from pylons import cache The first imports a decorator which makes possible to cache entire controller methods, the second imports a function to use client side caching and the third makes available a caching repository where to store whatever data you might want. The easiest caching mechanism is etag_cache, this tells to the browser to use its own cached version of the page if it has any available instead of requesting it again […]
I was looking for a way to propagate exceptions from my tg2 app to the ErrorController to permit to propagate errors from controllers to the user. To generate errors and show them you usually have to redirect to /error/document and pass as parameters the error message and error code, but this isn’t really flexible and also modern languages have a really good feature to propagate errors: Exceptions. So I was looking for a way to raise a webob.exc.HTTPForbidden, place a message inside it and let the ErrorController render the message. Usually you don’t want to tell to the user what went wrong with your 500 server side exception, but you might want to tell to the user why he can’t […]
