Iterating descendants of base Z Class, how?
by Alexander Staubo 09 Jun '99

09 Jun '99

Let's say I have a base Z Class "Project". Then I have a descendant Z Class "WebProject". Is there a way to get a list of a folder's objects that are project objects or descendants? For example,  ... will only give me instances of the base class Project, _not_ any WebProject instances. In order to do both, I have to do  ...   ...  But while this works, it's pretty inflexible, especially as I intend invent new subclasses of Project, and I do not wish to rewrite this DTML code every time I do. I realize I can possibly enumerate the meta types through the Control Panel, and then do objectValues() on each of the class names, but this smells like a bitch job. -- Alexander Staubo http://www.mop.no/~alex/ "`Ford, you're turning into a penguin.

Optional date properties (Zope 1.11)
by Alexander Staubo 09 Jun '99

09 Jun '99

I thought I could add an optional date property to my Z Class' property sheet, but no -- it seems Zope requires that you fill in a valid date. Is there a workaround? Isn't this inconsistent with other properties' behaviour, though? Wouldn't it be logical that an empty date value as entered in Zope's management screens would represent "None" or at least a generic "zero" date? -- Alexander Staubo http://www.mop.no/~alex/ "`Ford, you're turning into a penguin.

Additional HTML-Header on ZServer FTP-get
by Stefan Bund 09 Jun '99

09 Jun '99

After I have read about ZServer and the FTP access method, I was really intrigued by the possibility to use emacs+ange-ftp to easily manage Zope Documents. After a bit of struggling with the Zope configuration I got it working: I LOVE emacs: I can open a file '/localhost:8021:/standard_html_header', edit it and then save it with C-x C-s and it will be changed in the Zope-Database. Cool. (I patched ange-ftp to support Port Numbers though...) Now to the Problem: Whenever I open a DTML-Document or DTML-Method, ZServer seams to add '<html><head></head>' as the first line. Saving the changed document then saves this additional HTML-Header... Bad... Is this a (known?) Bug in ZServer? I'm using ZServer Version 1.0b1 with Zope 1.10.2 and ZPublisher 990415. Another question: How does ZServer determine the type of Object to Add when put-ing a new File? Stefan.

> From: Robert O'Connor [mailto:bob@rocnet.com] > Where does Z Tables fit into the big picture? > * Is it replaced or enhanced with ZODB3 ? ZODB is the underlying Zope database. ZTables (at heart) is a way of publishing desktop data (like DBF files) on the web and augmenting that data with very fast indexing, hierarchical views, and other zope niceties. ZTables puts your uploaded data into ZODB. (At my job before I came here to Digicool, it's a product my old company could have benefited from tremendously. Instead, they converted all the DBF records to _INDIVIDUAL_ html files and searching was done with Glimpse. Ugh. Fortunately, a crafty Bobo app done by yrs truely made that a slightly less painful experience. But ZTables would have solved so many of the problems that we couldn't). I'll let Paul answer the rest. > * Is it or will it be open source? > - If not, What does it cost?

O'Reilly Open Source Conf -Aug 21-24
by Robert O'Connor 09 Jun '99

09 Jun '99

I just got the O'Reilly Open Source Software Convention brochure. http://conferences.oreilly.com There is a track on Python and the Pre-Conference Tutorial includes "Introduction th the Zope Web Application Server" from 2pm to 5:30pm on Sat Aug 21st. Also "Community: Funding the Perfect Beast... Venture Capitalism, IP and Open Source" from 2pm-4pm on Monday, Aug 23rd. I'm sure Paul and Digicool will have an official announcement but this seems like a good thing to announce now for the Zope community. -Bob OConnor bob(a)rocnet.com

I should get on the ball and release a new beta now that 2.0a is out. When you say 'no real SMTP or POP3 server', that's wrong. Zope is not a mail server. In order to use NotMail, you will need an SMTP and IMAP server. IMAP is like POP3, but much more functional. NotMail is an IMAP Client that gives you a web interface to your mailboxes. -Michel > > > > _______________________________________________ > Zope maillist - Zope(a)zope.org > http://www.zope.org/mailman/listinfo/zope > > (For developer-specific issues, use the companion list, > zope-dev(a)zope.org - http://www.zope.org/mailman/listinfo/zope-dev ) >

The first kind (represented by the 'open box' in the Control Panel) is a through the web developed product. Using these products, and factories, object, and maybe ZClasses, you can develop a Zope product through the web. You are not required to know any Python to make a product like this. You do, however, need to know the process by which you create a product. See Amos's ZClass tutorial in the list archives. The second kind of product (represented by the 'close box' in the Control Panel) is a pure python product. The Poll product is one of these. it is written in python and all of it's files are read off the filesystem. The reason Zope says 'Broken Poll Product' is because there is a problem somewhere in the Python code of the Poll Product. The Poll Product dates all the way back to version 1.9, so I'm guessing that a change somewhere in Zope from then till now is causing the Poll product to break. If you click on the (broken) Poll Product, there will be traceback tab that takes you to the traceback view. Cut and paste that traceback into a mail message and send it to the list. -Michel > --zhaoway > > > _______________________________________________ > Zope maillist - Zope(a)zope.org > http://www.zope.org/mailman/listinfo/zope > > (For developer-specific issues, use the companion list, > zope-dev(a)zope.org - http://www.zope.org/mailman/listinfo/zope-dev ) >
