Workflow, Python and Zope

Here I just repost a statement from Michael (wftk(a)vivtek.com) concerning his workflow product (http://www.vivtek.com/wftk.html, Open-source workflow toolkit). Maybe it's useful for some further developments.

Last modified - including contents?

Two questions related to presenting 'last modified at ...' message on HTML page. 1) I have some pages (for instance my website news page or some indexes) which are dynamically build from another pages (usually via dtml-in - reading elements of some type from some folder). Does there exist any easy way to present the _newest_ bobobase_modification_time for all used elements? Currently on my news page I show 'last modified at 2000/08/14' although in fact this page has been modified at '2000/09/16'... 2) Similar question related to marking website parts as 'New' or 'Recently changed' in different indexes. What is the easiest way to calculate date of the newest change in the whole folder hierarchy starting from the given folder? Thanks in advance for any hints. -- http://www.mk.w.pl / Marcin.Kasperski | Moje prywatne strony: http://www.kasperski.prv.pl @softax.com.pl | @bigfoot.com \

FW: [Zope-PTK] Date Question
by Scott Burton 20 Sep '00

20 Sep '00

This is the correct list :) ---------- From: Scott Burton <scott(a)launchpoint.net> Date: Tue, 19 Sep 2000 14:27:46 -0700 To: <zope-ptk(a)zope.org> Subject: [Zope-PTK] Date Question OK, I have searched everywhere for the answer to this. It is quite simple but I can't seem to figure it out. All I want to do is iterate over cataloged objects(<dtml-in "Catalog(meta_type='object_type')">) and only show items who's bobobase_modification_date matches today's date. I just can't figure out how to set the fmt="%d" in an if tag.

I use zdiscussions with no problems since zope 2.0.0 to 2.2.0. I didnt test it with (zope>220 and zope<222). Now I'm testing it with 222 and for the first time its broken. -- Júlio Dinis Silva _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

Re: [Zope] Strange CSS inclusion BUG

That is a dtml-if caveat! The dtml-if documentation says that dtml-if caches its variable value to save time, in case the variable is in fact a function that takes long to call. What happens in your case: <dtml-if local_css> looks up "local_css" and because it is callable, it gets called (i.e. rendered). The result is a string. This string is bound to "local_css" inside the <dtml-if>...</dtml-if>. Therefore, "local_css.absolute_url" results in the error you observed. You can replace <dtml-if local_css> by <dtml-if "_.has_key(local_css)">. This will not be equivalent to "<dtml-if local_css>" but good enough for your purpose. If you want to emulate it more faithfull, you could use: <dtml-if "_.has_key(local_css) and _['local_css']"> This is equivalent ot "<dtml-if local_css>" with the exception of the caching. Dieter

Strange CSS inclusion BUG
by Li Dongfeng 20 Sep '00

20 Sep '00

To use CSS file, I put the following line in the head of HTML files: <dtml-if local_css> <link href="<dtml-var "local_css.absolute_url()">" rel="stylesheet" type="text/css"> </dtml-if> Where "local_css" is a DTML document containing CSS style sheet. But the DTML generates the following error message: Error Type: AttributeError Error Value: 'string' object has no attribute 'absolute_url' If I strip the <dtml-if protection, the code works OK. Why is the DTML document local_css changed into a string after <dtml-if>?

can I suppress newlines/whitespace in DocumentTemplates?
by Skip Montanaro 19 Sep '00

19 Sep '00

I'm starting to use DTML to generate plain text output. Generally speaking, the amount of DTML used to represent a particular chunk of output is much longer than the output itself. For instance, something like <dtml-var "_['start'].strftime('%m/%d%y')"><dtml-if "start != end"-->-<dtml-var "_['end'].strftime('%m/%d%y')"></dtml-if--> will expand to something as short as 9/25/00 or 9/25/00-9/26/00 I'd like to structure my DTML so it is vaguely readable: <dtml-var "_['start'].strftime('%m/%d%y')"> <dtml-if "start != end"--> -<dtml-var "_['end'].strftime('%m/%d%y')"> </dtml-if--> This means inserting newlines and doing some indenting. Unfortunately, since I'm generating plain text, the newlines and indentation count (unlike with HTML). Is it possible to tell the formatter to either ignore whitespace around the current location or turn off implicit whitespace rendering altogether? <dtml-comment> seems like overkill and would add a lot of <tags> to the total amount of text my eyes have to analyze. If it matters, I'm using Zope 2.2.1. I'm currently using the DocumentTemplate.HTMLFile class, but could easily change if one of the others provides more convenient default behavior. (Would it be possible to subclass File or HTMLFile to get the behavior I want?) Thx, -- Skip Montanaro (skip(a)mojam.com) http://www.mojam.com/ http://www.musi-cal.com/

flat file db, favorite links, and zope
by sean＠horse101.com 19 Sep '00

19 Sep '00

Hi, I have a comma delimited file which holds favorite links info for my site and is used by Perl to display and add new ones. I want to use something Zope related but don't know Zope that well yet (don't know Perl much but enough to recycle another's script). Anyway, I have all of these links in a file and don't want to loose them. I would like to continue to allow site visitors to add to the list (selecting their own categories, etc) and have the db managed easily my me. What are my best options? Should I use some sort of Zope product to handle this? If so, does one of them allow me to use my existing db file (at least import it)? I could, I suppose run Perl via Zope if I had to but there must be a better way (I would not be sure how to do this either). Any advice would be appreciated. --Sean

More Import Problems
by Joshua Brauer 19 Sep '00

19 Sep '00

As a horrid workaround for the earlier problem with Z-classes I exported all of my data, restarted Zope and am re-importing, or would like to re-import data, but some of it won't import back into the same install that it came from. I re-imported the products and then want to re-import the parts of the site.... I get the following error: Error type: ImportError Error value: cannot import name query Traceback (innermost last): File /websites/Zope/lib/python/ZPublisher/Publish.py, line 222, in publish_module File /websites/Zope/lib/python/ZPublisher/Publish.py, line 187, in publish File /websites/Zope/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook (Object: ApplicationDefaultPermissions) File /websites/Zope/lib/python/ZPublisher/Publish.py, line 171, in publish File /websites/Zope/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: manage_importObject) File /websites/Zope/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: manage_importObject) File /websites/Zope/lib/python/OFS/ObjectManager.py, line 504, in manage_importObject (Object: ApplicationDefaultPermissions) File /websites/Zope/lib/python/ZODB/ExportImport.py, line 207, in importFile File /websites/Zope/lib/python/SearchIndex/TextIndex.py, line 217, in ?

Import Problems
by Joshua Brauer 19 Sep '00

Here's another try at getting this question addressed.... I have 2 Zope installs. On the newer one (2.2.1) when I try to import KM Net News (to install in the products list) I get the following error. Note I previously deleted KM Net News (the earlier version) but think that Zope might have gotten killed right in the middle of the delete and not completely deleted the product. Is there any way to get rid of the Class ID KMYear that does not show up in any way through the interface?
