Maybe it should read "We don't know how >to use Zope or code in Python." No it probably means that in enhydra they can solve any problem with brute force, just like you can in asp and php. Ie. if you have trouble understanding the security mechanism in Zope you are lost until you understand it. If you have trouble with the Enhydra security mechanism, you can allways write your own. Sometimes you can get stuck in Zope for days, without knowing how to proceed, or without knowing how to find out, because you simply got to do it the Zope way. In a commercial setting that is very dangerous when you work on a deadline. In a simpler system you have to do more yourself, but you won't be painted into a corner as easily, as you can allways do a "hack". to solve your problem. Zope is more closed in that regard. Well anyways when you know enough about Zope to make a hack, you probably also know how to do it the right way. But it's only a matter of documentation AFAIK. Regards Max M

verify whether html <input type=file... is empty
by Andrei Belitski 17 Jan '01

Hi! Don't know if it is really a zope question, but I have a problem, verifying if e.g. input <INPUT TYPE="file" NAME="image_1" SIZE="50"> is empty or not using <dtml-unless " REQUEST[ 'image_1']=='' "> <dtml-call "manage_addImage( id=imageId, file=REQUEST[ image_1], REQUEST=REQUEST )"> </dtml-unless> well, I think the <input type=file... is not a string, but what I want to test is if the user put in the filename and not whether the really existing file is empty, so how could aI do it? I would appreciate any hints Thank you in advance Andrey

Andrey, One way would be to simply test for it on your form action page. <dtml-if "image_1 == ''"> <p>Sorry! You need to include an image.</p> <dtml-else> <dtml-call "manage_addImage( id=imageId, file=REQUEST[ image_1], REQUEST=REQUEST )"> </dtml-if> Jamey > -----Original Message----- > From: Andrei Belitski [SMTP:andrei.belitski@student.uni-tuebingen.de] > Sent: Wednesday, January 17, 2001 9:16 AM > To: zope(a)zope.org > Subject: [Zope] verify whether html <input type=file... is empty > > Hi! > Don't know if it is really a zope question, but I have a problem, > verifying if e.g. input > <INPUT TYPE="file" NAME="image_1" SIZE="50"> > is empty or not using > <dtml-unless " REQUEST[ 'image_1']=='' "> > <dtml-call "manage_addImage( id=imageId, file=REQUEST[ image_1], > REQUEST=REQUEST )"> > </dtml-unless> > well, I think the <input type=file... is not a string, but what I want > to test is if the user put in the filename and not whether the really > existing file is empty, so how could aI do it? > > I would appreciate any hints > Thank you in advance > Andrey > > _______________________________________________ > Zope maillist - Zope(a)zope.org > http://lists.zope.org/mailman/listinfo/zope > ** No cross posts or HTML encoding! ** > (Related lists - > http://lists.zope.org/mailman/listinfo/zope-announce > http://lists.zope.org/mailman/listinfo/zope-dev )

ZWiki --> MS Word
by peter bengtson 17 Jan '01

17 Jan '01

Searched zope.org, the z mailing list and google.com (the only search engines I use these days) I'm looking for some tool to convert ZWiki text to MS Word. Reason being that my boss wants it in MS Word, and I do all my typing as ZWiki's. Any solution is welcomed! Since ZWiki's are CaPs neurotic, some sections are called for example: "OrganiSations" or "PaGe". Also the text has these references. Bare in mind, that it doesn't have to be a native Zope or python thing, but I post it here in hope. /Peter

slow response with 2.2.5b1, 2.2.5, 2.3.0b1 win32 version
by clamor＠fafalter.de 17 Jan '01

17 Jan '01

Hi, beginning with Zope 2.2.5b1 I noticed some latency between requests and responses (about 3 seconds) even of simple pages. This applies to the 2.2.5 and the 2.3.0b1 releases as well. It occurs only on win32 installations. The 2.2.4 release runs fine on the same machines. There was a similar post by the end of last year, but unfortunately I didn't find an "enlightening" ;-) answer on the list. Anyone else with the same phenomenon? Any suggestions?

2Q: Catalog and REQUEST
by alan runyan 17 Jan '01

17 Jan '01

I have a calendar each day is a radio button and the name=schedule_mmddyyyy when I post to a page I want to do something like, get all the values that start with 'schedule'. I found no examples on how to iterate over the REQUEST objects values. anyone? times=[] for key in REQUEST['form'].keys(): if key[:8]=='schedule': times.append(REQUEST['form'][key]) second question: I have some searchResults() when I say <dtml-in searchResult><dtml-var sequence-item></dtml-in> (when are we going to get rid of sequence-item?) I get instance None instance instance instance but <dtml-in searchResults> <dtml-if "_['sequence-item']!=None"> <dtml-var sequence-item></dtml-if> </dtml-in> doesnt work. running on the latest beta, really nice :) ~runyaga

case insensitive searches
by Maggie Shapland 17 Jan '01

How does one do a case-insensitive search using sql methods when the underlying database is case-sensitive? Although I can force the search on the database to look for a lower case string, I cant make the person giving the value give me the value in lower case, and I know I shouldnt use dtml-var due to security reasons. I guess I really want the dtml-var attributes implemented in sql-var since lower(fieldname) like <sql-var "'%' + fieldname + '%'" type=string lower> does a case sensitive search whereas: lower(fieldname) like '%<dtml-var fieldname lower>%' works fine since it forces the user input to lower case ---------------------- Maggie Shapland, Computing Service, University of Bristol, Tyndall Av, Bristol BS8 1UD Tel: 0117-9289869 (Int 9869) Email: Maggie.Shapland(a)bristol.ac.uk Web page: http://www.cse.bris.ac.uk/~ccmjs/ 1925 Lanchester 21, 1925 Talbot 10/23, 1929 Peugeot 190S, 1986 Moss Monaco

ZClass Adding Magic Needed
by Geoffrey L. Wright 17 Jan '01

17 Jan '01

So: I have a odd little problem that I can't seem to solve. I have two zclasses. We'll call them zclass1 and zclass2. zclass2 lives inside of zclass1. zclass1 has the following two properties: id and displayOrder. zclass2 has the four properties: id, displayOrder, alignment and content. In both cases the id is an automaticly generated unique number based on ZopeTime. My problem is that I need to make a public add method that generates a new instance of zclass1 with a new instance of zclass2 inside of it. I also need to be able to control set the displayOrder of zclass1, and the alignment and content of zclass2 from the same form. The displayOrder of zclass2 will be static for the time being, but I'll ultimately need to control that as well. I hacked the default add method of zclass1 so that it generates a new instance of zclass2 each time, and using the Job Board HOWTO I managed to make a public add method. So far so good. But now I can't for the life of me figure out how to pass some form variables to one object and some to the other, especially while they have some identically named properties. Any hints on this one? //glw
