keeping original dates of objects when importing zexp ?
Hi, The question is in the title ! Has someone a suggestion fo this ? Thanks in advance. --Gilles
The answer is that you should not rely on bobobase_mod_time as the application modification date of your objects. You have uncovered a good reason why. Your application should instead store and update the mod date on its own, like the CMF does. You could argue (and I would generally agree) that there should be better built-in support for this at the Zope level, but this is a trickier problem to solve in a general way then it first appears. Modification means different things to different apps. -Casey On Thursday 18 July 2002 12:50 pm, Gilles Lenfant wrote:

Thanks Casey. In my case, I transered some ZWiki from an old server to a new one. Zwiki pages display their dates based on their bobobase_modification_time :(( I added to the Zwiki a custom view based on the most recent Zwiki pages. This view is now screwed. When CMF object keep the dates in the meta data. Of course a "retain existing object dates" would be fair in the import form (like for the ownership).

any "retain existing date" just cannot work if the date is using bobobase_modification_time. that's because bobobase_modification_time has nothing to do with the application itself, it is a ZODB database-level value that cannot be "set" from any application. only the database itself can manipulate it. jens On Friday, July 19, 2002, at 08:02 , Gilles Lenfant wrote:

What about when just using copy and paste? The dates all change to current when using copy and paste. Any way to change that? -Allen ----- Original Message ----- From: "Jens Vagelpohl" <jens@zope.com> To: "Gilles Lenfant" <gilles@objectis.net> Cc: <zope@zope.org> Sent: Friday, July 19, 2002 9:07 AM Subject: Re: [Zope] keeping original dates of objects when importing zexp ?

no there is not. copy and paste creates a new database record, which obviously then has a new bobobase_modification_time. your application should keep track of modification time itself in a separate property of your item. jens On Friday, July 19, 2002, at 09:30 , Allen wrote:
