Weird Date Display Bug in HTML Form
by Dan Shafer 23 Apr '02

23 Apr '02

I have an HTML form with a text field into which I wish to place the current date, properly formatted, as a default value. In the form, I have the following DTML: < input type="text" name="start_date" value=<dtml-var "(_.DateTime().strftime('%b. %d, %Y'))">> This code is copied verbatim from another page on one of my other Zope sites where it produces the day's date just beautifully. In this case, it only displays the first formatted element (day name in this case, but I've proven that it will display the first item whatever it is) in the form's text field. If I use the exact same code in a textarea multi-line field on an HTML form, it displays the entire formatted date correctly. Known bug? Workarounds? Personal insanity?

I thought that I documented this pretty well. If you had trouble finding this frome the Parsed XML documetation, it's a bug that should be filed. NodeType is a DOM implementation feature, which is described by the W3C docs and linked to in several help screens. There is also discussion on the Parsed XML & Zope XML wikis, linked to by the docs. The DOM interfaces that Parsed XML implements are listed in the Parsed XML docs, and any deviations from this list are also bugs that should be filed. -- Karl Anderson kra(a)monkey.org http://www.monkey.org/~kra/

Hello, Anybody know why if I have: from urllib import urlopen, urlencode, unquote_plus and then something like: print unquote_plus(innerlist[1]) the string WILL NOT come out unquoted for some reason?

Returning data as XML from a python script?
by Alec Munro 23 Apr '02

23 Apr '02

Hi all, I'm trying to set up a fairly generic system for retrieving data from a database and bundling it so that it can easily be placed in any front end medium. For the moment, this means simply finding a data format that I can use in both HTML and Flash. I'm fairly certain that I could get Python to return XML easily, but the question I have right now is: is there an easy way I can leverage this so that Python doesn't care whether it was a page template or a flash movie that made the call, and that it will work in either situation? I love Flash, but I know many people don't, and we don't have the budget for redoing our entire site anyway, so it is a given that HTML will be the presentation medium of choice. But I would like to have the data there if I want to put a Flash front-end on a specific page. As I understand it now, Flash would be happy simply receiving the text of an XML document, and then parsing it into useful information, while ZPT would prefer to have an object that it can reference the properties of. Is there an easy solution? I suppose I could simply have a wrapper class for HTML, Flash, and any other mediums we choose to utilize? Well maybe I answered my own question, but I'm a Zope newbie, and I have yet to make extensive use of Flash's XML streaming facilities, so I would appreciate if everyone would throw in their comments on this, as I'm sure there are many things I am overlooking. Thanks for your time, and I'm really sorry if outlook mangles this. Alec Munro EOA Scientific Systems

WebDAV access from MS-Office
by Thomas Guettler 23 Apr '02

23 Apr '02

Hi! Is someone accessing zope from MS-Office with webdav daily? What are your experiences? Some weeks ago there were several complaints that files were not accessible because they were read-only. My application will have about 30 people using it at one time. The files will be regular office files. The avarage file size will be around 100-300kByte. The network will be a 100MBit Ethernet. Is it possible to use umlauts in file names? thomas

All right, I made DCOracle2-PR1 and copied the dco2.so to my /usr/lib/python2.1/site-packages/ directory.

Re: [Zope] Inserting a variable in a context.manage statement in Python

Fantastic! This was exactly the missing key, Tim. Thanks very much! I think this was the last major technical gap I had before I can complete this application. This list is wonderful. You are most helpful. One more reason to keep using Zope and Python.
