Mmmhh, so my answer is not to derive my classes from Persistent. Will it then actually store the object in the ZODB? How does that work? That is the C part of Zope and I am not too efficient with C.

If your method changes data then it will always get saved. The only way is to make sure your method never modifies a persistent object. > -Original Message- > From: Stephan Richter [mailto:[EMAIL PROTECTED]] > Sent: 23 January 2001 11:11 > To: [EMAIL PROTECTED] > Subject: Re: [Zope] Python Products and ZODB Transactions > > > > >Use the tranalyzer to see which objects are being commited. > They think > >they are being modified, even if you dont think they should be. > > Okay, I found the methods and they are sometimes changed.

I really would like the >ZODB to never save any of my Products actions. Any ideas? Use the tranalyzer to see which objects are being commited. They think they are being modified, even if you dont think they should be. http://www.zope.org/Members/tsarna/Tranalyzer Toby Dickenson [EMAIL PROTECTED] ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
