Opensource DBMS for WIN?
by Paul Zwarts 24 Jan '01

24 Jan '01

Greetings, Was wondering if there was an open source dbms to use with Zope on a Win2k machine...? I found references of using cygwin to run PGSQL (which we have on our unixbox) but would prefer something that doesnt run over an extender-shell... TIA, Paz

dtml-in sql => dtml-in anything?
by Joh Johannsen 24 Jan '01

24 Jan '01

Is it possible to replace an existing ZSQL method with an identical Python External Method that behaves exactly the same way? So if I have a ZSQL method "GetThingFromDB" <dtml-in GetStuffFromDB> got a <dtml-var thing> </dtml-in> Can I replace "GetThingFromDB" with a Python External Method? I've discovered that if I return a list, then that list gets returned one item at a time. But what value does each item have? I'd like to just have the external method return exactly the same thing as the ZSQL, but I'm having some problem finding what format (if any) that is. Is this sort of thing even possible? Thanks, JJ

Re: ZClasses and "title" property
by Tim Moore 24 Jan '01

24 Jan '01

I guessed it was something like this, so this leads me to two followup questions. 1) I'd be happy to use the built-in title property assuming that it won't cause some kind of problem. I just don't know how I can set that in instance objects since it doesn't appear on the property sheet. Can I modify the addForm and add methods for the class to set it there? Do I need to make a custom view? What approach do most people take in this situation, using the built-in title or choosing a different name for a title-like property? 2) The tutorial in the Zope Developer's Guide instructs you to add a "title" property to CDClass (http://www.zope.org/Documentation/Guides/ZDG-HTML/ZDG.6.2.4.html) I haven't actually run through the tutorial exactly, but I assume from my experience that this won't actually work. Maybe this part of the guide should be changed to reflect this (as well as other sections that also use "title" as an example property). Thanks for the responses!

No. They allow you to check whether the conditions are met. You are free to decide what you do in this case. The easiest thing is to raise an exception. This results in a preconfigured error response, which probably is not too useful. You may look for a recent message to this list about DTML contracts. It may give you most of what you want. Dieter

Can anyone offer any advice? You should search the (searchable) list archive. You will find at least one thread that discusses this issue. You may also find a HowTo at zope.org. Dieter

Re: [Zope] Adding users with a PythonMethod

Can't be! You can use REQUEST in a PythonMethod, too. Either pass it explicitly as parameter or use "self.REQUEST" to access it. Dieter
