Project Description

Introduction

This package provides a hook into Zope’s ZPublisher that is run after the publisher has completed traversal and authentication, but before it tries to publish an object. This is practical for tasks such as tracking user activity.

Hooks use zope.event’s event mechanism using the plone.validatehook.interfaces.IPostValidationEvent. This is based on the standard ObjectEvent form zope.component.

The IPostValidationEvent event has two attributes: user which is the currently authenticated user object and request, which is the current request object.

Keep in mind that even unauthenticated requests have a user object. If you only want to deal with ‘normal’ users make sure you ignore any instances of AccessControl.User.SpecialUser.

Example

As an example we will write a bit of code which logs the id of the current user and the path to the current code. This is the code for the event handler:

from zope.interface import Interface
from zope.component import adapter
from plone.validatehook.interfaces import IPostValidationEvent
import logging

logger = logging.getLogger("LogRequest")

@adapter(Interface, IPostValidationEvent)
def LogRequest(object, event):
    if getattr(object, "getPhysicalPath", None) is None:
        path="Unknown path"
    else:
        path="/".join(object.getPhysicalPath()

    logger.info("Request from user '%s' for object %s" %
            event.user.getId(), path)

To use this code you need to register it in zcml:

<subscriber handler=".events.LogRequest" />
