How to install Zope on SuSE 6.1
by Eric, Stacey and Lydia Miller 18 Aug '99

18 Aug '99

Hi. It's the WNT-developer-to-Linux-wana-be again. I gave up on my CheapBytes edition on RH 6.0 and purchased SuSE 6.1 for various reasons. I tried to install Zope 2.0.0b4 after recompiling the 1.5.2 version of Python (with threads). No dice. I can't get it to work. I tried to run ZServer and get the following: -------- 1999-08-18T01:53:31 PROBLEM(100) ZServer Computing default hostname -------- 1999-08-18T01:53:31 INFO(0) ZServer Medusa (V1.10) started at Tue Aug 17 20:53:01 1999 Hostname: ERIC.ALPHAQUADRANT.ORG Port:8080 -------- 1999-08-18T01:53:31 INFO(0) ZServer FTP server started at Tue Aug 17 20:53:01 1999 Authorizer:None Hostname: ERIC Port:8021 -------- 1999-08-18T01:53:31 INFO(0) ZServer Monitor Server (V1.5) started on port 8099 Traceback (innermost last): File "/usr/local/Zope/Zope-2.0.0b4-linux2-x86/z2.py", line 494, in ? IOError: [Errno 13] Permission denied: '/usr/local/Zope/Zope-2.0.0b4-linux2-x86/Z2.pid' Now, if I understand this correctly: A. ZServer doesn't like to compute the default hostname or can't. B. ZServer Monitor Server does not have permission to create and or update the file Z2.pid. I tried giving full rights to the subdirectory (777), etc. but this does not make a difference. If I try instead to use the version of Apache that SuSE installs I can run the test-cgi script just fine but can not run Zope.cgi. Under RH 6.0 I could at least get Zope.cgi to run (of course I could never get the auth rewrite rule to work.) I've searched the list email for help and found that someone else has the same message when they start up ZServer. I checked with him and he can't get it to work either. So, either he isn't begging enough or nobody knows how to get this to work. If someone would take pity a poor Win developer trying to migrate to Linux and Zope at the same time and help me install this thing so that I don't have to learn Java and Enhydra... ;^) Eric Miller phoenix(a)cac.net ejmiller(a)sweetsystems.com

Getting some documentation started....

So you guys at Digi did this right, and we'll be seeing Bradfords draft documentation here for review soon(ish) right? And whilst we're here if you'll tell me how to search through all the Zope objects in my site by some attribute and then display some (other) attributes, basically like a SELECT statement but not on a database instead on Zope itself(see I'm really new) I'll write that FAQ/chapter too...

Compile/install as one user, run as another
by Scott Michel 18 Aug '99

Let's assume that I compile up Zope as myself but I'd like to start the Zope daemon up as a sandboxed user (chroot-ed, etc.) What are the critical files that the sandboxed user needs to be able to read and write?

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.
