Breadcrumbs Navigation Trail

"How-to" create a navigation bar that shows how you got where you are so you can get back out. The term "breadcrumbs" alludes to Hansel and Gretel who left a trail of breadcrumbs on the ground to help them find their way out of the dark forest. Unfortunately, a flock of Catalog objects came along and ate all the breadcrumbs.

Using ZClient to Access Another Server

Sometimes you need to get data from another server and serve it as if it came from your server. For example, you want to show the current weather from www.weather.com on the front page of your Intranet site. Or your main server is on Unix, but you want to get data from Microsoft databases on an NT server through another Zope on that machine. The program client.py can do this for you, but it's an external Python program. This How-To shows how to make a simple external method that lets you use client.py from within a DTML method.

ZClass Properties

A "how-to" that shows a few basic tricks for managing property sheets in a new Z Class.

Xron -- Zope Scheduled Method Dispatcher

Xron schedules procedures for Zope applications -- similar to what 'cron' does for Unix applications. You define a special kind of DTML method and specify when you want that method to run. When the specified time arrives, Xron calls the specified method.

Frozen Logger -- Stupid_Log Helper Product

Sets environment variable STUPID_LOG_FILE to something like /<INSTANCE_HOME>/var/FrozenLogger.txt (if it is not already set). Use for Zope ISP accounts that don't give you control over environment variables (but do let you install Zope products).

ZScheduler

ZScheduler has been superseded by Xron.
