Can anyone point me to a good TAL tutorial for people who have difficulty getting to grips with it?
Assuming you have read and practiced the 2 chapters on ZPT in the Zope book I would also recommend peterbe's "DTML2ZPT Conversion examples", even if you have never done DTML, these are a collection of common code snippets: http://www.zope.org/Members/peterbe/DTML2ZPT After that keep in mind that anything complicated enough to need "python:" in a TAL statement should likely be moved out to a python method. (That could be either a python script through the ZMI, or even better a method of your filesystem based python product.) The results of the python method can then be placed in the option space and accessed very easily from the ZPT. A common usage scheme is to always call the python method through the web, which assembles all needed data and then returns the ZPT with the data as parameters. Have fun! Regards, Sascha
