November 1999 - Zope

Zope mentioned in Linuxpower article on PHP
by Adrian Esteban Madrid 18 Nov '99

18 Nov '99

Here goes a link of an interview of the programmers behind PHP that mentions Zope. The interviewer mentioned Zope as a possible threat to PHP and the programmers explained a little bit more on how the two are different and all. Better take a look at it at http://www.linuxpower.org/display_item.phtml?id=149 (you shouldn't trust my english anyway ;-) -- Adrian Esteban Madrid Network Support, ATS Brigham Young University

PCGI processes are getting stuck
by Duncan Booth 18 Nov '99

18 Nov '99

Something weird has happened on our main Zope server which is running on NT behind a Netscape Enterprise server. I thought I had it all sorted out so that I could access it both through PCGI and directly on another port, but the pcgiwrapper processes don't always seem to terminate and the server gradually clogs up with a large number of them. Has anyone else seen a similar problem, and if so have they any idea what is causing it? -- Duncan Booth duncan(a)dales.rmplc.co.uk int month(char *p){return(124864/((p[0]+p[1]-p[2]&0x1f)+1)%12)["\5\x8\3" "\6\7\xb\1\x9\xa\2\0\4"];} // Who said my code was obscure? http://dales.rmplc.co.uk/Duncan

A very interesting and thorough test: http://www.postgresql.org/mhonarc/pgsql-general/1999-11/msg00227.html Test report includes sources. PostgreSQL comes out very well I think. -- Martijn Pieters, Web Developer | Antraciet http://www.antraciet.nl | Tel: +31-35-7502100 Fax: +31-35-7502111 | mailto:mj@antraciet.nl http://www.antraciet.nl/~mj | PGP: http://wwwkeys.nl.pgp.net:11371/pks/lookup?op=get&search=0xA8A32149 ------------------------------------------

RE: [Zope] Help with Z Search Interface and ranges
by Willie Peloquin 18 Nov '99

18 Nov '99

Hi, Could someone point me to an example of a Z Search Interface that will allow me to search for instances with less than or greater than type values: ie. price between 10000 and 15000 price >= 10000 and price <= 15000 I really don't understand how these pages are working. I have appended the search and report DTML that was generated in a small sample database I created. How do the items in the form get transfered to the 'report' dtml, via the URL? Does the report parse the URL to determine the search parameters, or is there a hidden method that I don't know about. Jeff sent me an example, but I don't quite understand it yet. Where would this fit into my 'report' and 'search' dtmls. It seems I have more 'fundamentals' to learn. Thank you all for your assistance, Willie >Take a look at: > http://www.zope.org/SiteIndex/newitems.html/view_source >where zope.org uses a lower-range on the date field to show all items >new within a recent interval of time.

ZDiscussions
by Ethan Fremen 18 Nov '99

18 Nov '99

Michel or somebody... I want to use the new ZDiscussions tool. I've downloaded & installed it, but I cannot find an iota of information on how to use ZDiscussions. I have looked in the Product files. I've made a ZDiscussions folder, and now I want to have the document to discuss with the discussion displayed below that. How can I do this? <dtml-var ZDfoldername> just gives me a <mybrains instance at blah>. Thanks, Ethan Fremen

Manage Methods
by "RC Compaan" 18 Nov '99

18 Nov '99

I created a simple user interface to manage items to a productcatalog. I use the same commands rename,delete, etc objects as is used in the Zope management interface and objects are selected with checkboxes. This is the Form Action: <FORM ACTION="" METHOD="POST"> The Form can be submitted in the following ways: <INPUT TYPE="SUBMIT" NAME="manage_renameForm:method" VALUE="Rename"> <INPUT TYPE="SUBMIT" NAME="manage_delObjects:method" VALUE="Delete"> When the form is submitted it jumps back to the Zope management screen, but I want it to refresh the current screen. Do if have to write my own methods to rename and delete objects or is there another way?
