Order of elements in folderish objects
by Ben.Peter＠t-online.de 17 Apr '01

17 Apr '01

Hi all, When presenting a site structure in a menu, the order of elements in a Folder or other folderish objects is (most likely) of some semantic relevance if this is to be done dynamically. In the management interface of folderish items, there is little possibility to rearrange the order of the elements, except for cutting and pasting, as new elements will be appended. While the management interface presents elements in alphabetical order, this will have the desired effect of changing the order when requesting the list of elements via objectItems(). This is, however, a rather clumsy approach. Is there some easy solution to remain flexible with this order, or will it be something like subclassing the relevant objects and add a property for the order by which the requested list can be sorted?

Please help! How do I start Zope as a client? And how do I make sure the other server is successful in running the ZEO server? I can only see two lines of processes. Thanks in advance.

Re: [Zope] zope + sql
by William Herring 17 Apr '01

17 Apr '01

I'll try. I have a list of records from a single sql table that are viewed by the browser using sql SELECT. I would like to go down and 'check' or mark certain specific records. Then, for only the records that are 'checked', I would like to use sql UPDATE to replace the a value for one of the variables. The value replaced for that variable would be the same for all of the marked records.

Hi ! How would umlauts have to be entered to be interpreted correctly by the structured text processor in Zope, e.g for a hyperlink ? "Füssen":Füssen, or even "Füssen":Füssen don't work. Any Help ? Thank you, and best regards; Stefan.

Re: [Zope] zope rant: It's all about delegation
by Luciano Ramalho 17 Apr '01

17 Apr '01

One word defines what Zope is all about: DELEGATION. If you work alone or your project is so rocket-science that it requires a team made 100% of highly skilled programmers, then it may be better for you to use plain Python and Zope parts (like ZODB and ZPublihser), Quixote, WebWare or your own framework. Most projects in the real world are not like this. Most sites must be managed and updated by users of varying skills. Corporate sites, intranets, content portals must be built with tools that allow easy and safe delegation of management powers to many people, from journalists and salespeople to web designers with little programming skills. If you can't delegate, you get backlogs, tech staff burn-out, frustrated users and unhappy customers. An interesting point: in another "Why not Zope" piece, Chuck Esterbrook says he prefers a syntax like the ASP and PHP <%%> tags than DTML. We believe DTML is actually a strong selling point of Zope. Combined with Python Scripts and SQL Methods, DTML encourages separation of layout and logic much better than ASP and PHP. To define dynamic templates, dtml-var, dtml-in and the occasional dtml-if are enough. With proper support of Python Scripts, complex DTML expressions can be avoided, making DTML very easy to read and modify by anyone who knows HTML. And ZPT can be even easier. In ASP and PHP it is very common to see SQL and HTML fragments embedded in the <%%> parts, which means that DBAs, programmers and designers all have to touch the same code to make changes. If your site is so small that one person has all three roles, then maybe you can be more productive hacking away SQL, HTML, PHP and client-side JavaScript all in the same document. But if your site is that small, you really don't need a content management system like Zope. In medium to large sites, there are never enough all-knowing sysadmin/perl-hacker/dba/web-designer old-style "web masters" to go around... So Andrew Kuchling's and Chuck Esterbrook's texts should really be called "Why Zope is not for me?" instead of just "Why not Zope?". Best regards, Luciano

Wondering if anyone has any input on how I can customize 404 messages that zope returns for files not found. I have reorganized my site with zope and I would like to let users know to revisit my main page. "Black Holes are where God divided by zero." -- Steven Wright

Another question about LoginManager (or similar products)
by l.p.arnesen＠usit.uio.no 16 Apr '01

16 Apr '01

After getting LoginManager working and following the steps of the LoginManager with SQL database HOWTO I realized that this was a solution to store administrators of the website in a database. I'm going to create a public service that requires all the users to register with a username and a password. After doing so they must log in every time they use the service. I really don't want to write the user login code if it exists in some form of a module or a product. Is there some examples of how to use the LoginManager to do this? PS: I guess I'm looking for a authentication mechanism like the one Mailman uses for it's administration pages. Yes, I can just take a look at how Mailman does it, but I guess there are some less complex examples to take a look at somewhere. :) -- Lars Preben

Alternative irc servers?
by Andy McKay 16 Apr '01

16 Apr '01

My firewall wont let me connect to irc.zope.net at work. I can get into other servers such as Webnet though. Has anyone had any success with another irc server so I can get into #zope during the day and waste all my time at work? -- Andy McKay.

RE: [Zope] zope rant
by Paz 16 Apr '01

I agree. This person is misguided and either a) Does not have the skills in Python the be able to understand properly what Zope can do and b) Have corporate requirements that go above and beyond what he expects from a package like Zope. I worked for Compuware's Uniface lab for some time and can say that he probably needs to spend the millions of USD to buy Uniface instead of complaining about Zope. It provides the logical layers between data and presentation that he speaks about with the security, but were comparing apples with elephants now. I would suggest he also be aware of Uniface's (multi)million line-plus of coding in their kernel, as opposed to Zope that is a small fraction of that. I'm a newbie myself and have built my own personal website entirely with ZSQl and DTML. As I learn Python, I go over the site and redo layers of it to fit the proper model that Zope can provide. I see no clear proof of his assertions against Zope as they certainly introspect that he has not taken the time to figure Zope out properly. Having worked for Tech Support at the Uniface lab, I've heard it all from customers. EVERYONE says how complex their application is... blah blah blah. 9 times out of 10, our specialists come back from the fields shaking their heads because the customers basically got caught in a corner by covering the exits with mountains made from mole-hills.... If your catch my drift.... Never blame the tools, screwdrivers can be useful for drilling holes, but only when you don't have a drill. Agreed, he has a point... I read his CV page about the MEMS exchange and albeit, Zope is probably not suited very well to his needs, since they made design decisions prior to Zope that greatly affect Zope's capabilities and behavior. But, he pays a great disservice to Zope users by not explaining this. I'm not a developer, so I'm not able to argue the tech attributes. I'm a project manager with little enough staff that I need to jump in myself here and there... and I love the experience of it. But the bottom line is that most tools like Zope can be exactly what you need providing the realization that certain steps need to be prepared first to align this decision. It sounds to me that he didn't have this opportunity and that's why Zope is downtrodden, but at Zope's expense, and not his own, which it should be. Unfortunate, but most development projects will undergo this 'rebuilding requirements' phase several times before getting it right. Its just unfortunate that he doesn't depict it as so. Paz -----Original Message----- From: zope-admin(a)zope.org [mailto:zope-admin@zope.org]On Behalf Of matt Sent: Sunday, April 15, 2001 4:27 AM To: Win GO; zope(a)zope.org Subject: Re: [Zope] zope rant Seems very misguided, and I think perhaps he is just very confused. For one thing putting ZClasses and Zope Products in the same category dosen't make sense to me. I tend to write a lot of Zope products as python modules and with that I get grep, I get CVS, I get test suites ... in fact there are tutorials around somewhere that show you how to run ZPublisher for debugging, it's an easy step to build the test suite around that. Next the talk about "Much of the application ends up as DTML" ??? that goes against most people's Zope philosophy, where DTML is a presentation layer ..... if you are writing your application in DTML and it works then well done!! but I wouldn't want to debug it. There is also this confusion with "dynamic scope", one of the most fantastic things about Zope is implicit acquisition. Sure it takes a bit to get a feeling for, but once you are there you start to organise your hierachies of attributes and methods into an environment that makes sense, and which is very powerful. If he is trying to build as they say "complicated objects", then through-the-web DTML is not really what they should be trying to do. Writing a python product would be the more obvious path. And if he/she finds editing in a Netscape text box so horrible for dtml and PythonMethods, then perhaps they could use their favourite editor and the nice FTP server that Zope comes with ... :-) Matt
