I have a couple of small patches here that allow you to override the
manage options (i.e. manage_tabs, manage_page_header,
manage_page_footer) in the ZODB. This simple patch seems a nice way to
provide this option without breaking compatibility with the current
system. It patches the App/Management.py and OFS/Application.py file.
This also causes risk of locking yourself out of management, there are 2
ways around this problem; First is to ftp/webDAV in and delete the
offending file.
I've also added a SUPPRESS_CUST_MANAGE option, (for example
abc/SUPPRESS_CUST_MANAGE/manage_main) when this is in the path it will
stop use the core zope management interface instead of the custom ones.
The problem with this is that i get a "<Override instance at 8189638>"
instead of the DTML code that should be in place of the object. As well
this option IS NOT thread safe. I'm looking for a better solution but i
can't think of one?
What do people think of this patch? Is there a better way to do this? Is
it possible to get a patch similar to this integrated into the Zope core
because it's an extremely useful.
Hope to hear from you soon
