Using FTP to connect to Zope server from (g)VIM
by Phil Harris 25 Mar '02

25 Mar '02

Hi all, My intellect was piqued recently by a discussion on the list about editors for Zope etc. I remember some people saynig that VIM was good, to which my response was, 'Yeah but there's no FTP built in'. Someone then responded with a few scripts to do it. Well I thought they were a bit cumbersome, so I wrote my own. ftpopen.py and ftpsave.py. If you have a VIM executable with Python support built in then these run from within VIM and allow you to open/save file from/to Zope seamlessly. (I have them on a menu in GVIM for instance) I'll put the files up on my Zope Members bit (http://www.zope.org/Members/philh) along with a few instructions. If anybody can think of any enhancements then please let me know and I'll see if I can work them in. I hope these will be useful to someone. See ya Phil phil.harris(a)zope.co.uk

*Designing* Zope sites
by Joel Burton 20 Sep '01

20 Sep '01

I've been learning about the workings of Zope: ZClasses, ZSQL methods, Python products, etc., and there are *lots* of resources about the APIs, and lots of products to add content to our sites. There is also lots of help on how to *set up* a Zope site: how to tie w/Apache, etc. What I haven't found yet, though, is much advice on how to *design* the Zope site: . effective ways to use User Folders . whether to make containing folders for like objects (eg book reviews), and collect these for lists with objectValues, or whether to add them under user folders/different contexts, and use ZCatalog searches to find them. . how to handle printable pages throughout a site . strategies for using ZSQL methods throughout a site and so on The Zope book tosses some nuggets of advice here and there, but doesn't build up a site, so we don't really get to see the workings of a talented Zope architect. Other documentation focuses on how to Do Things, like use SQL methods, or how to build products. I've had a little bit of time to look at the CMF, and that has some structure about reviewing, etc. (and seems to advocate the 'place things in user folders, use ZCatalog to find' method); however, I'm not designing something that seems so portal-ish, and this seems like a hegemonic solution to a design question. So: Am I missing any resources on fitting it all together? Are there 'example sites' that someone could describe? Would anyone with a well-designed site be willing to export it all up and post it somewhere, so we could explore it? Or are there other ways of starting this learning path? -- Joel Burton <jburton(a)scw.org> Director of Information Systems, Support Center of Washington

Re: [Zope] Zope management screens and OmniWeb (on OS X)
by Dominique.Dutoit＠cec.eu.int 05 Sep '01

05 Sep '01

Same problem here. But I think that the problem is elsewhere because I don't have any problem to manage my personal folder on zope.org with OmniWeb. Maybe the problem is authenticating an user when there is a port number in the URL. Or the way zope.org does the authentication is more friendly that the authentication window. I have tried to run zope on a port 80 but Python refused to bind the port and I'm sure that Apache is not running. It seems that Mac OS X protects some resources. By the way, iCab has exactly the same problem and yet, it works with the personal folder. Dominique

Difference between zope and apache
by Jan-Frode Myklebust 18 Jul '01

18 Jul '01

Hi, I've just noticed an annoying difference in the handling of directories in zope. If I create an directory /myDirectory, put an index_html file there, and a my.css file the index_html should use in the same directory refering to it with <link rel=stylesheet type=text/css href="my.css"> in the head of my document I get a structure that would work perfectly fine in apache, but not in zope. /myDirectory /myDirectory/index_html /myDirectory/my.css Accessing http://example.com/myDirectory in zope would give me the files http://example.com/myDirectory/index_html and http://example.com/my.css In apache the server would return a location header like: Location: http://example.com/myDirectory/ and then my browser would know it should ask for http://example.com/myDirectory/my.css Zope doesn't seem to set the location header, so asking for http://example.com/myDirectory/ http://example.com/myDirectory returns different results if the index_html contains relative URLs below /myDirectory/. Bug or feature? -jf

Need a good Postgres Database adapter.
by Stuart Foster 20 Jun '01

I've used the ZPyGresSQLDA product for a couple of years now. Yet on my new installation of Zope with Python 2 I can't get the product installed. Anyone know of an adapter that works with the newest Zope and Python? Stuart

Re: [Zope] Stopping a <dtml-in>

Wow. That's good to know. I just created some fairly ugly code to get around the lack of something like a dtml-break. I just tried searching for it on zope.org, on the mailing lists, and using google for good measure. Didn't find any mention of it anywhere. If anybody does come up with a link I'd love to see it. I wonder why there's nothing like that natively..? //glw

In my experience, this a a pure client-side bogosity. To verify: try blowing away all the 'nsform*' and 'formpost*' files in your "C:\windows\temp" directory; if the problem clears up, make an effigy of Mark Andreesen, abuse it creatively, and call me in the morning. :) Tres. -- =============================================================== Tres Seaver tseaver(a)digicool.com Digital Creations "Zope Dealers" http://www.zope.org

newbie: ZClass as a multifolder prototype
by Milos Prudek 05 Jun '01

05 Jun '01

Can i create a ZClass with folders? As far as I can see, I cannot put folders into ZClass definition. I know I can have ObjectManager as a superclass, and then I can add folders to any ZClass instance. But is it possible to have folders in ZClass definition? -- Milos Prudek
