I prefer creating and manipulating
the content entirely in the setuphandler.
You have to be careful, normally, the created conted will be removed
on uninstall/ reinstall
loosing all changes done to the content since initial installation.
to prohibit this,
you can use
a beforeUninstall hook
inside an Extensions/Install.py
like:
def beforeUninstall(self, reinstall=False, product=None, cascade=[]):
""" Prevent created content from being deleted on uninstall
"""
if 'portalobjects' in cascade:
cascade.remove('portalobjects')
return True, cascade

My question: what is the current thinking on programmatic content
creation during product install?
First let me say I'm a great fan of Aspeli's repeatable site creation.
Anything I can do in code and configuration once is better than
re-doing it over and over through the ZMI.
I'm developing a base site framework for testing. The framework is
simple, and to my liking so that I don't have to go into the ZMI and
change workflows, user options, etc. I create a couple users with
different privileges and populate the site with some content.
That's the rub.
For example, I want a new front-page. The current logic seems to be:
* Add a new-front-page object using
CMFCore.exportimport.content.importSiteStructure
* Modify the properties/state of new-front-page using a setuphandler
As I see it, a site/product creates content using one mechanism and
then massages it using another.
There is also a GenericSetup/doc/SampleSite package that appears to
create new entities. But I couldn't get it to work. All it seems to
do is call Products.GenericSetup.utils.importObjects to build
new XML structure, but nothing else seems to happen.
It looks like importSiteStructure is the mechanism to use and
SampleSite
is deprecated. I most definitely could be wrong.
Soapbox: it seems to me a little awkward to use XML files everywhere
and
then CSV for content creation. Why does
CMFCore.exportimport.content.importSiteStructure
use a CSV format instead of XML?
One idea is to call desired factories in my setuphandler and modify
the instances all in one place.
