[Zope] Error importing objects 2.8 > 2.7
*Been working up some code on a zope 2.8.0 install, and I wanted to move it over to a live server. I keep getting this error: Error Type: AttributeError* *Error Value: 'module' object has no attribute '__newobj__' The new server is curious becuase it reads: * Zope Version (unreleased version, python 2.2.3, linux2) Python Version 2.2.3 (#1, Aug 8 2003, 08:44:02) [GCC 3.2.3 20030502 (Red Hat Linux 3.2.3-13)] This was an RPM install as far as I remember. 2.7 I think Do I need to get 2.8.0 on this production box, or is there an easy fix to get this .zexp imported? thanks for any tips! -e- ___ 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 )

I keep getting this error: i've had problems moving stuff (zclass, .zexp) between 2.7 and 2.8 iirc, there were major changes between the two. your best bet would be upgrading your live server to 2.8 too hth-- http://myzope.kedai.com.my - my-zope org ___ 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 )

Of course, you might be happy when you can import into a newer Zope version from an older one. At least, that makes some sense :-) Of course we would be happy if we could do that. But export/import was never designed to deal with migration issue. This is very much an application side problem. Btw. Jim has written a "generations" module which looks like a promising framework to deal with implicit migrations in a sane way. -aj pgpilPy98CwYt.pgp Description: PGP signature ___ 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 )

Export/import is essentially what the ZODB does all the time. If export/import does not work between given Zope versions, it is quite likely that the same Zope versions will have difficulties with storages exchange -- and this *IS* a migration issue, Zope should be concerned with (and not the applications). If it does, export/import will simply follow (in most cases). -- Dieter ___ 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 )

Possibly we are talking about different things. A most common mistake of Zope especially Plone users is to think that export/import acts as a migration tool (export your Plone 2.0 site on system A and reimport it into a Plone 2.1 installation on system B). This does usually never work when the internal data structures have changes (you know that :-)). Supporting such migration support for Zope core was/is always a goal since we have the app (Zope) in our hands but we can not sell export/import as a universal migration tool. 3rd-party apps have to deal with that. -aj pgp5Md1HrQ98W.pgp Description: PGP signature ___ 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 )
