It seems that your environment is different for interactive start and start during boot.

Is there anybody out there having no problems with Zope and Oracle > databases? I'd really like to know that. We have little problems.... Beside something corrupting the heap. I do not yet know, what is to blame -- but maybe in a few days. Dieter

There is a HowTo at zope.org about how to control Zope via ZClient from cron. Dieter

You can either rename your DTML var or your SQL column result name: DTML var: <dtml-let myspam=spam>  <dtml-in sqlstuff> .... <dtml-if "myspam == spam">....</dtml-if> .... </dtml-in> </dtml-let> SQL column result name: select spam as sqlspam ... You now access the "spam" column under the name "sqlspam". I, regularly, use SQL column renaming. Dieter

The "with" tag with the "only" attribute starts a new stack and pushes the object onto this new stack. Inside the "with", you will only see attributes of the object itself *or* attributes that the object acquired. This "or" is the problem. Acquisition and namespace stacking are orthogonal. You strip the namespace stacking with the "only" attribute (of the "with" tag), you strip the acquisition context with the "aq_base" attribute (of the object). Dieter

Netscape & Open session with NT active user
by Vincent 27 Jul '00

27 Jul '00

Hi, In fact, it is not just a question about Zope, it is a question about Netscape : When you protect a directory and ask for a password, I would like to know if Netscape is able to access to the parameters of the loged user (under NT). PS : In fact, I would like that the users do not need to enter twice their login/password. Thanks Vincent

RE: Zope Tutorial

> I'm an absolute newbie at zope, and I can't get your tutorial running > (Windows 2000, cookies enabled). Here's what to do: * Get Zope 2.2, download it, install it. * Log in to Zope with the super user account. * Create a manager account by going to the User Folder and adding a new user, and giving them the Manager role. * Quit your browser to log out. * Log into Zope as the manager you just created. * Create a Zope Tutorial, by adding it from the product add list. * Now do the tutorial. Good luck! -Amos -- Amos Latteier mailto:amos@digicool.com Digital Creations http://www.digicool.com

Downloadable Zope reference and products?
by Marcin Kasperski 27 Jul '00

27 Jul '00

Is it possible to download in some way complete zope reference and zope products? In case anyone is interested why do I need it: I have fast internet link at work. I have time to study Zope at home. -- Marcin.Kasperski | Users typically do not know exactly what they want @softax.com.pl | and are unable to articulate all that they know.
