Simple question
by Arnaud Lecat 19 Aug '99

19 Aug '99

Hi I've made an "images" directory like this / |_ images |_ news |_ etc.... How can I access images contained in this directory from other directories ? Ok, images all have an ID but I don't want to give the path by myself... Is there an automatic procedure or must I define a property which contains the name of my image directory, and then I'll write something like that  Seems strange to me ;( -- >> WinErr: 080 Clavier introuvable - Veuillez appuyer sur n'importe quelle touche pour continuer. << Arnaud LECAT >> Email: lecat(a)hexanet.fr >> WWW page:www.hexanet.fr/~lecat HEXANET >> http://www.hexanet.fr Z.A.

Re: getting some documentation going:(getting long here..)
by Lindon Parker 19 Aug '99

19 Aug '99

Oh dear, first it's nice of Michael to send a reply. But can any of you Digital Creations people see what the problem with the answer? Well before I go critcising it, first let me say I'll have some off-list discussion with Michael to see if I can get the sort of documentation going we need. But (and I'm sorry Michael to be picking on you - I KNOW its not you fault) what those "giving up in frustration" people are talking about is the fact that there is NO answer here(as is often the case in other replies/documentation - obviously NOT written by Michael by the way). This reply tells me how great ZCatalogue is(how fast etc. etc.) and how I can work with ZClasses(if I design them "right"). In effect this is a piece of either developer enthusiasm(always good to see) or marketing blurb(and if your frustrated already you can easily pick this option - I'm choosing not to by the way). So what this doesn't do is tell me how to search Zope objects by attribute value, which was the question I asked. It is in turns too much information and too little. So what I want to see is a simple piece of code that lets me search my Zope database where I can, as a complete novice, substitute my objects and my attributes to get back a list of things I can itterate over. Lets ignore perfomance, b-tree's, ZClass design etc. etc. Assume I have NOT installed ZCatalogue(unless of course it comes by default on my NT Zope 2.0 install, does it?), and I'm using DTML Documents. In short assume I am an idiot(you wont be so far wrong) but I need to get something working pretty quickly, and I'll make it graceful later. OK now the specifics are out of the way I want to quickly offer up a view on why we need to stop the development process(or slow it down severely) and address the documentation issue. In a word "SPECTRA". This is the new content management tool from Allaire, based on their ColdFusion web/database interface. Recently Allaire were out here doing demo's and training, we were invited, and attended. So basically it's in the same domain as Zope and it's VERY powerful. It will not by the way be the last product in this domain, but right now it's shaping up to be the competition for Zope. Now I don't really mind if Digital Creations don't think it is the competition, it is as far as potential customers are concerned(well the potential customer I work for anyway). The good news is that it's about Aus$12,000 per copy and wont really be ready for prime time for about 8-12 months(we think). The bad news is that it WILL ship with VERY VERY good documentation. In fact the ticket price isn't such a differentiator either; anyone (including you guys at DC) who thinks Zope is free is really fooling themseleves, ticket price is but one(small) component in the overall cost of software, poor documentation is another soaring cost to organisations such as ours. So the only real advantage left is the 8-12 months window, which we need to use for documentation. Now we might all think Zope and the python/OO technologies around it as well as its inherent design, flexibility, extensibleness means we have a better product here, and that only a deluded fool would use a relational based blah, blah, blah product. But the reality is that Allaire will beat us out here(they have a lot of experience with volume delivery) if we don't meet them on MANDETORY issues like good documentation. We have an opportunity to keep this area of our industry open, with the use of Zope. But it will pass us by if we dont get good documentation soon. This is but one of a range of arguments made here for getting on the documentation-for-dummies bandwagon. Phew that got really long, sorry to take so much of your time.

OSES - Another ZopeSite
by cg＠cdegroot.com 19 Aug '99

19 Aug '99

The Open Source Educational Software, a new project aiming at developing platform-independent classroom software/courseware, is on-line at www.oses.org running Zope. I'm a relative Zope newbie myself, so if people find the project interesting enough to want to help out, you're more than welcome to volunteer. The idea is not unlike the new Zope.org beta site: provide a portal where people can show off their software and HTML courseware, although the emphasis will be towards teams, not individuals - methinks that even with ZPT integrated, this'll take quite some work (so if you have ideas on how to accomplish this, please shout).

Zope 2.0 final release update...
by Brian Lloyd 19 Aug '99

Hi all. Here's an update on the plan for the Zope 2.0 final release: We plan to release a beta 5 this week with fixes to the must-fix bugs that have been reported to date (including the various hanging and stuttering problems that have been reported). Unless new showstopping bugs are reported, then 2.0 final will probably come out about a week (give or take a few days) later.
