If you look at the results of this sample of Debian installations, in the section `web packages' (http://people.debian.org/~apenwarr//popcon/results.web.html) the top 20 are like this: Package Vote Old Recent Unknown apache-common 461 87 35 0 apache 457 36 20 0 wget 434 334 88 0 lynx 407 169 21 0 junkbuster 163 29 3 0 mozilla 143 145 89 0 squid 139 2 3 0 htdig 84 16 2 0 wwwoffle 66 1 1 0 weblint 60 266 25 0 analog 58 105 51 0 webalizer 50 48 9 0 zope 49 15 9 0 imp 40 1 1 0 apache-dev 38 126 29 0 php3 37 75 52 0 tidy 31 127 15 0 boa 29 1 6 0 konqueror 28 0 50 0 apache-perl 28 4 1 0 (About 924 individual computers submitted results this week. - Vote: Number of people that use this package regularly. - Old: Number of people who installed but have not used the package recently. - Recent: Upgraded the package too recently for stats to be valid. - Unknown: No files in the package were used in the statistics calculation.) For sure this is by no way a representative sample of all Debian installations. FWIW, if it was representative, it would suggest that Apache was installed on half of all Debian installation, and that Zope was installed on 5 % of all Debian installations. You could start and multiply that with an estimate of the number of Debian installations (no idea, something in between 5e4 and 5e6, I'd guess ;-) to end up with some 2000 up to 200000 installed Zope Debian packages. What exactly did Churchill have to say about statistics ? Gregor

Your thoughts about Zope-based database apps
by Alonso Rhenals 08 Nov '00

08 Nov '00

I'm considering implementing a web-based database application with MySQL as a back-end and a Zope-based front-end. I wonder if you could provide your thoughts on the following questions: 1. Is Zope a good tool to quicky build an efficient & effective user interface for a database application? 2. In particular, what would be the best way to implement the inserting and updating of records along with input data validation? (Retrieving data from a database to show on a web page using Zope is straightforward as you know.) 3. In several cases I'd like to implement a main form/subform, where the subform allows the user to enter several items related to only one record in the main form. Since every item might have many fields (say 20) I'd like to present just the most important fields on a table, and allow the user to view/enter/update all the fields for each item in a different web page. Those of you familiar with Microsoft Access know that in Access it is straightforward to implement this main form/subform interface. I wonder what would be the best way of implementing this using Zope? 4. Do you know of any existing Zope-based app similar to this?. Obviously, the back-end doesn't have to be MySQL. 5. Finally, if somebody is interested in further discussing this type of applications, I'll be glad to participate. Just e-mail me to rhenals(a)ieee.org Thanks in advance for your inputs.

What should I do? Perhaps <dtml-var "folder.filename()"> will do? It executes the method "filname()" and returns the result. Regards Max M

Zope loses by not >having a decent external storage mechanism for its programming. Whoa there ... I didn't say anything you could disagree with. I just stated facts. But I do agree that writing software in Zope is a problem for me too. I would also like a flat text storage system, but I also see why it is difficult considdering the design choices made in Zope. I believe that my problems stems from the fact that code, content and presentation is to strongly interwoven. zClasses are nice and simple but difficult to edit, as it has to be done in the browser. Or at least pasted into it. You also get yourself painted into a corner pretty quickly. Subclassing a Pyhton class as a base for a zClass is kind of nice. But currently I am having problems using that method as it seems that "helper classes" cannot be adressed from dtml methods in the zClass. (Se my acessing parameters in a "helper class" posting). Products are difficult to make, and all the tutorials are rather bad. Business logic and presentation is mixed together. (Business logic should not use any code or libraries from Zope at all.) A nice way to work would be to make a Python class that is completely independent of Zope. Test and debug it. Then make a thin Zope wrapper that adds just enough functionality to make it work in Zope, and so that it can be accessed nicely via dtml. I am trying this approach currently, but it gets ugly real fast. It will probably be nicer when I understand it fully. I Will post a How-to then. Regards Max M

Ok, so this works: def extmethod(self, REQUEST): return str(REQUEST) >From the web that prints the string Representation of REQUEST. But, over XMLRPC, this: s=xmlrpblib.Server("http://server.name/Zope/path/") s.path.extmethod() Returns the string representation of REQUEST, but *this* s.path.extmethod('rrr') return 'rrr'.

newbie: comparing dates?
by Georg Rellensmann 08 Nov '00

08 Nov '00

Hi all, another newbie-question: - I created a zclass with three date properties. - Now I´d like to display the most recent of these dates in directory-listings etc. QUESTION 1: How do I compare dates in dtml code? QUESTION 2: How do I exclude empty values from processing? (I installed rapto´s null date-patch, seemed to work fine; for that patch see: http://www.zope.org/Members/rapto/nullDate?pp=1) regards, -georg.rellensmann-

How to access control panel debug information as normal user??
by Gilles Lavaux 08 Nov '00

08 Nov '00

Hello, I want to give to my normal users (non manager) the possibility to access some debug informations like: - the number of currently open connections + the date of the openning. (This mainly to track the hanged request...) I am not able to retrive this information, except as manager. Whatever security or role I set on my 'status' method: <dtml-var standard_html_header>  Status:<br>     <dtml-var standard_html_footer> Thanks for any help Gilles Lavaux

Okay, I got the <dtml-var filename> to work right assuming that that files are arranged properly according to aquistion, but then when I try to get the file from another folder like <dtml-var "folder.filename"> It displays the code of that page rather thatn recognizing that it is content. What should I do? Thanks; Chris
