Re: [Zope] Upgrading a Product from Zope 2.7 to Zope 2.10
I'm not an expert at these kind of things but 3 tips: * Don't bother with trying to run off the old Data.fs until you get your product working in the new Zope. * Inspect your code and what kind of objects (and most likely more importantly) and attributes you're attaching to classes that are persistent. I've forgotten my case now but I remember that I had a problem when I was trying to set an attribute that turned out to be a uncalled class method of another class. * Get familiar with this: 'import pdb; pdb.set_trace()' On 19/03/2008, Mark Hellewell [EMAIL PROTECTED] wrote: Hello, I'm in the middle of trying to upgrade a Product written for Zope 2.7 so that it runs on Zope 2.10!

Try to reproduce this problem in an interactive Python session (bin/zopectl debug under *nix). Use pdb.pm() to analyse the post mortem traceback. Look at the object that causes the problem. If you are lucky, the object gives you hints where the error has been introduced. -- 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 )
