I'd look at: (a) UserDB, (b) ZSQL Methods, and (c) a Database Adapter (DA) for your favorite, platform-capable database The UserDB will let you create Zope users that are stored in a relational database. ZSQL Methods and your favorite DA (e.g., SybaseDA, ODBCDA, etc.) will give you the connectivity to the rdbms. A lot depends on what you want to do with the user object. --Rob

possible bug w/ CatalogAware?
by Alex Rice 17 Aug '99

17 Aug '99

I have not posted this to collector yet. If it looks legit, let me know and I will post it. Please let me know one way or another, so this one doesn't get forgotten. Using Zope2 beta 4, I have ZClass which inherits from CatalogAware (Basic Tab says "Base classes ZObject, _ZClass_for_CatalogAware") A DTML method defined in ZClass which edits a propertysheet and calls the reindex_object() method of CatalogAware. (The point is to get the Catalog to keep up to date with edits on the ZClasses it is cataloging.) The symptom is strange. The dtml method is named editSelf(). Like this, it works as intended: <dtml-call "propertysheets.info.manage_editProperties(REQUEST)"> <dtml-call "RESPONSE.redirect('reindex_object')"> However, like this, it doesn't appear to call reindex_object, or it just doesn't do anything: <dtml-call "propertysheets.info.manage_editProperties(REQUEST)"> <dtml-call reindex_object> Any ideas on this? I would very much like to not be forced to issue a redirect to get the reindex_object to take place. Is there any more documentation available on ZCatalog especially CatalogAware? -- Alex Rice | alrice(a)swcp.com | http://www.swcp.com/~alrice Current Location: N.

RE: [Zope] Giving up in frustration

I've come across the use of 'Zen' in Python contexts: this is the likely origin, I would guess... But there's no question that without a certain Zope-Zen, it's extremely weird to start poking below the surface of this puppy. Some days I have it, some days I don't. At the same time, the *way* it's difficult is also what makes it powerful. And when you "get it", it's extremely easy to do extremely powerful things --flexibly-- and in more than one way. Perhaps the UNIX types here are more familiar with that phenom... > -----Original Message----- > From: Anthony Pfrunder [mailto:s341625@student.uq.edu.au] > Sent: Tuesday, August 17, 1999 7:14 PM > To: kent(a)goathill.org > Cc: zope(a)zope.org > Subject: Re: [Zope] Giving up in frustration > > > On 17 Aug 1999, Kent Polk wrote: > > > On 17 Aug 1999 09:35:01 -0500, Michel Pelletier wrote: > > >Ah yes, the Zen of Zope.

How could I do it...
by O.l.i.v.e.r T.h.u.n.s 17 Aug '99

17 Aug '99

Hi! I want to rewrite a simple ZPublisher banner exchange to a Zope app. I'm new to Zope and I don't know how I could to it. What I need is a way to create user accounts (need not to be Zope users) which different fields. A new user should submit a HTML form with password, name, email, etc. and a ne user account should be created (user object?). The user should be able to modify or delete his user account data.

The Zope Content Manager Guide does have a chapter on Roll-Your-Own Products that I've recently added some material too. It needs to be expounded on a lot to come to grips with ZClasses and advanced Product development. As another note however, creating your own Products and ZClasses is no less trivial that writing Zope 'Products' in python. Many of the high level concepts needed to write good python code are still needed to 'write' good ZClasses within your Products. > Re the "Use The Source, Luke" comments: I never had to read a single > line of Python source to understand it.

Not magic, just some really different and powerful technology that no one else has thought of yet. Nobody really knows where the 'Zen' moniker came up but it's not a bad analogy; when you come over to Zope you have the unlearn a lot of things that other technologies have taught you. If you come from PHP or ASP, you have to learn the OO differences in Zope, such as seperating tasks from data (layout from content). If you come from Roxen, you're probably familiar with template languages (DTML is a lot like RXML), but not with the fundemental object/component nature of Zope. > Suggestion: (Sorry if this has already been proposed) don't stop > development, or releases, etc. From what I can see, it > should be fairly > simple to create [with Zope -- doh! :-] a documentation > structure and a > mechanism to allow individuals to add to the docs.

All of our 'Guides' are written in FrameMaker. This can be converted into XML and stored in our CVS in that format instead of the native FM format. These checked in files can be uploaded into Zope as XMLDocuments and traversed by a simple Guide Reader application and made fully text searchable with the Catalog.

publishing headlines
by Tim Wilson 17 Aug '99

17 Aug '99

Hey Zopesters, I'd like to publish science and technology headlines on our science department's Web site. The headlines would be culled from an external site such as the BBC. This would be akin to the Slashboxes on Slashdot. Being a Zope newbie, I'd appreciate it if someone could provide an outline to implementing this feature. I'm not sure how to begin. This would obviously be of use to the Zope Portal Toolkit. -Tim -- Timothy Wilson | "The faster you | Check out: Henry Sibley H.S. | go, the shorter | http://slashdot.org/ W.

Questions about the future Zope-Concept and MySQL for NT
by Juergen Specht 17 Aug '99

17 Aug '99

Hi there, i am new here and discovered Zope yesterday. It's a great product and exaktly what i need here for a private project... I hope this list is the right place for my questions (and not only the place to discuss personal things) and i apologize for any questions somebody posted before, but i can't find them in the archives... I am running on my testmachine Zope 1.10.3 Version with WinNT as a service with Apache 1.36. I still need Apache in front of Zope. Is it possible to run the newer versions of zope with apache also? Or do i *need* to use the internal webserver? And: has anybody a precompiled and workable version of the MySQL DB-Adapter: http://www.zope.org/Download/ZMySQLDA for WinNT? Thanx in advance, Juergen <js(a)anima.de>

Deleting/renaming standard_html_header/footer

It would be really convenient if these ended in _html so I could teach my editor to use HTML syntax highlighting, shortcuts etc. on these documents. Any way to rename them other than editing the source code?

Are you sure 'news' contains a method named 'shownews'? If you do and this doesn't work, this might be a bug in Squishdot. Although nothing comes to mind why this would not work. -Michel
