Content Management System
by Seb Bacon 13 Oct '00

13 Oct '00

This query started out in a separate thread about permissions, but it's sufficiently important to me to pose again here. I've been struggling to make the CMS abilities of zope user-friendly enough for 'joe average' end-users. Really it's designed for a 'power' content manager who delegates, secures, and generally has taken the time to study all the Content Management docs, etc. However, most of my clients don't have those kinds of requirements and aren't that technologically savvy, so I end up coding ultra-simplified interfaces for them on a per-project basis. I know you can restrict permissions on just about every available method, and I am aware of the current skinnable zope project, which may improve the situation drastically. But I'm interested to know, how many of you offer the Zope TTW interface to clients as a content management system, and how many just use it as a development interface? I'm beginning to wonder if content management and system administration should be split out into separate subsystems. Or if a CMS Tool Kit should be developed. (workflows, syndication, etc...). But I'm still far from being a zope power user myself, and have yet to appreciate the range of its potential. What do you people think? Seb.

Re: [Zope] help!- version locked up site

Are you completely unable to access your site? Apparently not, as you can try to delete the version. Try to go to your version, use the "save/discard" tab and discard (or save) your version. This should remove the look. If you can no longer access your site, it might help to delete "var/Data.fs.tmp". Be carefull! Make a backup before! I do not know, what will happen. Dieter

Thanks for the follow-ups on Medusa Monitor. But as I can see (after using Zope for 1.5 years, now), few people actually use it. Unless one is really into the guts of Zope itself, the monitor is pretty useless for debugging. It of course could be made more useful, but one must implement some Python programs first. Even for dynamic reloading of modules, I usually just write External methods to do the job, instead of firing up the monitor. A more useful debuging tool would be some monitor where you can receive print message logs in real time. That would be great, especially if you have multiple thread problems. regards, Hung Jung _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

Re: [Zope] Any limit on number of users?

"UserFolder" uses a dictionary to manage its users. This implies, if one user object is accessed, the complete dictionary is brought into memory (if it is not already there). This might pose problems for a very large user number. Dieter

Rik, I've upped both the Zope_book.lit and the Zope quick Reference. The ZQR is not as readable as the zBook due to the formatting. I'll get the XML and reformat it to look a bit better. hth Phil phil.harris(a)zope.co.uk ----- Original Message ----- From: "Rik Hoekstra" <rik.hoekstra(a)inghist.nl> To: "Phil Harris" <phil.harris(a)zope.co.uk> Sent: Friday, October 13, 2000 8:25 AM Subject: Re: [Zope] Thanks for the comments > > > Phil Harris wrote: > > > > I'll stick onto my Zope members page > > > > http://zope.org/Members/philh > > > except that the http://www.zope.org/Members/philh/zope_book.lit is dead > ;-) > > Rik

I would suggest, you replace your "SQL method" (the complete "dtml-in") with "<dtml-var REQUEST>" and analyse what form variables do arrive. Dieter

Computed attribute access (was: [Zope] dtml-with syntax question)

It seems (though it is not clear) that you want a computed attribute access? Your "objectName2" is an attribute of "objectName1" and contains the "id" of an object in "folder.subfolder"? Then, you use "_.getattr". That's for accessing an attribute you have the name for (and the name is not constant). In your case, you would use it as: <dtml-with "_.getattr(folder.subFolder,objectName2)"> Dieter
