[Zope] ERROR ZODB.Connection Couldn't load state for 0x04
Zope 2.9.7 Apparently, I've done something bad and created "cross database reference". At least, that's what I gather from googling the ZODB error. I have 3 filesystem storages. One contains a ZCatalog that references objects in the other. Is this the cause of the error? I can't start zope now - how can I recover from this? 2009-04-13 10:46:24 ERROR ZODB.Connection Couldn't load state for 0x04 Traceback (most recent call last): File "/home/zope/zope_2_9_7/lib/python/ZODB/Connection.py", line 732, in setstate self._setstate(obj) File "/home/zope/zope_2_9_7/lib/python/ZODB/Connection.py", line 786, in _setstate self._reader.setGhostState(obj, p) File "/home/zope/zope_2_9_7/lib/python/ZODB/serialize.py", line 617, in setGhostState obj.__setstate__(state) AttributeError: keys ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

[Zope] Multiple zope instances using the same storage
I have an unusual setup. I have 4 distinct Zope instances (4 seperate Data.fs'). Each Data.fs is identical - Data is kept in a RDBMS. I have a product I need to install that stores data in the ZODB. This data is stored in one folder. Now, I *think* I can simply mount this folder in each ZODB and serve the storage through a ZEO server - however I've never done this setup, so I want to make sure this makes sense and I'm not overlooking potential problems. This is a legacy setup that I'm not responsible for, so I'm trying to keep my footprint in this setup as small as possible. Using Zope 2.7.9.

Re: [Zope] Five and editform
Hi JeanMichel, thanks for our reply. This is not an egg - just a simple product I have in /lib/python. I'm working with Zope 2.9.7, not a buildout environment. I get the Boring product in the "Add" dropdown, and I can create the object. I do have the product included in site.zcml, and it does implement the IBoring interface. Any other ideas? I read somewhere that I have to include this: And read somewhere else that five:traversable is deprecated. In any case, including or not including this makes no difference.

[Zope] ZCatalog Strategy
I'm struggling to weigh the cost of getObject() vs. the cost of adding more metadata to the catalog. I'll explain my situation. I have 10,000 widgets cataloged. I do a path and date query that returns me maybe 12 of these. Then I have a choice of calling getObject().getData() on each of these, or I could add getData to the catalog metadata. Does the cost of calling getObject() for a dozen objects justify creating a new metadata field? More generally how does a large amount of metadata in the catalog affect performance of queries? The wisdom of those more knowledgeable than me would be appreciated.

I assume user A and B have different roles? Instead of dynamically controlling
the permission, could you set the permission on the object explicitly when the
object is edited?
e.g.
def manage_edit(self, ...):
...
if REQUEST.get('category') == 'other':
self.set_permission_so_user_B_can_access()
elif REQUEST.get('category') == 'financial':
self.set_permission_so_user_A_can_access()

Re: [Zope] DateTime and TimeZone
It seems that since the Pacific timezone is in daylight savings time,
the correct offset is -7.
So nevermind.

[Zope] DateTime and TimeZone
I installed zope 2.7.6 on a windows 2000 machine. This machine is set
to the pacific timezone.
When I run python from the command line, and check DateTime, I get:
>>> from DateTime import DateTime
>>> DateTime()
DateTime('2005/09/06 23:55:29.620 GMT-7')
The 'GMT-7' is the Mountain timezone. The actual time should read
DateTime('2005/09/06 23:55:29.620 GMT-8') for the Pacific timezone.
What controls the default timezone behavior of DateTime on Windows? How
can I get this working correctly?
