Bug in <dtml-in size=1>
by Marcus Gruendler 09 Aug '00

09 Aug '00

Hi, I am working on a project with Zope. Unfortunately I am having a problem whith the <dtml-in > tag. I am using the batch processing feature and want to show only one element per sequence. I do this by setting size=1 and orphan=1. But th <dtml-in> tag only iterates over the first two records (I have 8 records). It iterates over all 8 records when I use size=2 orphan=1. I think this is a bug. The problem seems to be in the correct value of next-sequence. Could someone tell me how I could fix this? Here is my code: <dtml-in showAdressData size=1 orphan=1 start=query_start> <dtml-if sequence-start> <dtml-if previous-sequence> <a href="<dtml-var URL><dtml-var sequence-query>query_start=<dtml-var previous-sequence-start-number>"><<</a> <dtml-else> << </dtml-if previous-sequence> [...] </dtml-if sequence-start> [...] <dtml-if sequence-end> </table> <dtml-if next-sequence> <a href="<dtml-var URL><dtml-var sequence-query>query_start=<dtml-var next-sequence-start-number>">>></a> <dtml-else> >> </dtml-if next-sequence> </dtml-if sequence-end> </dtml-in> -- Marcus Gruendler eMail: runner(a)tamalin.de WWW : http://www.tamalin.de/runner/index.html

Input/output error w/ Portal News Items
by ralf.herold＠charite.de 09 Aug '00

09 Aug '00

Hello, after having moved to Zope 2.2 and fiddling with updating a Portal based on the PTK, I get rather strange errors when trying to read a news item. (I am posting this to both mailing lists because I do not know which one this error could related to.) There is _no_ error immediately after restarting the Zope, but after several seconds/accesses, the error message below raises. Additionally, there is _no_ error when I access the very same item as a registeres Portal user, but it raises again if tried to access as (anonymous) guest. Error Type: IOError Error Value: [Errno 5] Input/output error with the traceback  Could you help to correct this, please? Are there any proxy roles to be set (I tried manager on recent_news and others, but none worked)? My installation includes a SiteRoot and TransparentFolder, and was ok before the upgrading (which apart from above is marvellous!).

getitem('string') but with HTML
by peter be 09 Aug '00

09 Aug '00

I have a rather simple setup. And all I want to do is to show some news content, but with the way I'm doing it, the HTML is not parsed. /root index_html view_each_news_html /news news_001 (MS ruined!) # a DTML Document news_002 (Peter on killin spree) # a DTML Document ... # lots of DTML Documents Index_html lists all available news and that works fine. All I do is that I list the documents' title together with their bobobase_modification_time. Each news item is linked as <a href="/news_folder/view_each_news_html?newsID=<dtml-var id>"><dtml-var title></a> In view_each_news_html: I first tried this: <dtml-var "_.getitem(newsID)"> But it didn't parse the HTML in it. Static view works. For example changing: <dtml-var "_.getitem(newsID)"> to <dtml-var news_002> I have tried both: <dtml-with news> <dtml-var "_.getitem(newsID)"> </dtml-with> And... <dtml-with "_.getitem(newsID"> <dtml-var "_.getitem(newsID)"> </dtml-with> But none worked. Question is, how do I render with the getitem() function? so that HTML is HTML and not just text (html_quote)?? Grateful, Peter

substring search on zcatalog textindex
by pja＠clari.net.au 09 Aug '00

09 Aug '00

Hi people, Got a slight problem. I've got a zcatalog with a heap of names in it, and I want to be able to search for and find a name, given I only know part of the name. I did have it going through the entire catalog and by using the substring function, had it only display a result if there was a match, otherwise it didn't display anything. This was ok until the catalog grew bigger. As it is displaying the results in batches of 20, if there is no match until say the 300th element in the index, then it will display a page with only the "previous 20 results" and "next 20 results" links, and nothing inbetween them, and by following the "next" link, you have to go through 15 such pages before you get to the actual matches. So the question is, does anyone know of a simple way to get the zcatalog to also find substring matches on a textindex? -- Peter Armstrong

strange problem using python
by Oliver Frommel 09 Aug '00

09 Aug '00

hi, while trying to figure out how to use Zope from Python I encountered the following problem. The first access to a dictionary shows me an empty one, while the next one produced the correct result (see dir(a.m)): >>> import sys >>> sys.path.append('/home/oliver/Zope-2.1.6-src/lib/python') >>> import Zope >>> a = Zope.app() >>> dir(a) ['Control_Panel', 'QuickStart', '__allow_groups__', '_objects', '_product_ac_permissions', '_product_meta_types', '_product_permissions', '_product_zclasses', 'acl_users', 'aq_order', 'copybases', 'footer', 'header', 'index_html', 'm', ... >>> dir(a.m) [] >>> dir(a.m) ['MySQL_database_connection', '_Access_contents_information_Permission', '_Add_Documents__Images__and_Files_Permission', '_Add_Folders_Permission', '_Change_DTML_Documents_Permission', '_Delete_objects_Permission', .... could anyone explain why this is the case? thanks Oliver

Problem (Urgent)
by Anvita 09 Aug '00

Hello Sir, I want to know does zope supports '.pfr' file for display (for dynamic font display)... As i have to create a website for indian languages that will display its contains using dynamic fonts.. My old site is www.cse.iitk.ac.in/users/geeta (u can see it to understand my problem) that has been built using a flat file system + needs fonts to be installed on client's machine for working, and now i want to redesign it using zope + keeping the files in a database (zope database/oracle) + dont want the fonts to be downloaded at client side... Here i have to display same data in say 11 languages and if we'll use dynamic fonts we'll have to have only one data in our database and if we'll not use dynamic font than we'll have to store same data in 11 languages in our database and than its size will be too large.. So, Kindly suggest me a solution.. Thanking you, Anvita Bajpai, Research Engineer, IIT Kanpur - India.

Please help! Install problems on FreeBSD I've installed ZOPE several times before on different systems (win(win98, NT, Linux) for testing purposes. Always logged in as root I never encountered any problems. Recently I finally decided to upgrade my web-site to a ZOPE-Site and that's when the trouble started. Without the root privilege I had experienced every single problem possible. But finally I managed to build both python and ZOPE. The OS is FreeBSD 4.0-stable and I used both the binary and source package. I how ever can not start neither of them. All I get is a bunch of error messages. I also would like to use ProxyPass and ProxyPassReverse configuration. Do I use w_pcgi.py or wo_pcgi.py to build ZOPE. I think since I will not be using pcgi it should be the latter. I am including the junk I got after trying to start ZOPE. Any help would be greatly appreciated.

problem
by Tom Deprez 09 Aug '00

Hi, When does the next-sequence-item exists? Does it only exists in the sequence-end face? I want to provide the following: Next Line1 Line2 Line3 ... Next Clicking on 'Next' will move to the next result set. The problem is that I seem not be able to put a Next link on top of the result set, because 'next-sequence-size', 'next-sequence' only exist in the 'end-sequence' phase. Is their a way to solve this? Probably there is, but I can't find it at the moment. thanks in advance, Tom.
