A groupware package for zope
by morten＠esol.no 19 Dec '00

19 Dec '00

For the last couple of months I've been working on a groupware package for Zope, named ZopeGUM. It has reached version 0.1.63 now, and it's in steady progress. All the planned components, like messenger, address book, calendar, todos, etc. are there and working now; though it's definently not ready for a production enviroment yet. Anyways, just wanted to let you all know. (And yes, I do appreciate feedback. =) -Morten

The question is ... how do I do it? I'd like to make the default textarea field quite a bit bigger -- but I wasn't able to explore my way to success in the interface, and about 20 mins of seaching has yielded no answers. Then again, it's pretty late, so mebbe I'm just being dim.... TIA for any help, //glw

Weired catalog_object problem in python product
by Grégoire Weber 19 Dec '00

19 Dec '00

Hi, I read about ZCatalog been _the_ method of managing and searching objects in the ZODB. So I decieded to do searches and lists of object using ZCatalog. After reading all how-to's/API-doc about ZCatalog, a lot in mailings lists and studying a lots of code (ZDiscussions, Squishdot, PTK) I tried to use ZCatalog the proper way. But there is one problem I could not solve for about 8 hours of work. A short description of what my code does: I have three classes (NewsManager, NewsItem and ContentFolder) caring about news items. If I am creating a news item, it's object gets saved and cataloged in the content folder (the content inherits from ZCatalog). The NewsManager object responsible about creating the news item is named news and resides in the same directory as the folderish content object does. So the directory structure is: /orgname/content (content object, inherits from Products.ZCatalog) /orgname/news (NewsManager object, inherits from OSF.Folder) Now the problem (for a step by step description see below): The news items are correctly created in the content folder. But the item is cataloged as it would reside in xxx/news/content (which does not exist). I use self.absolute_url(relative=1) (called by __uniqueCatalogId()) to generate the catalog id (see manage_afterAdd below). It seems (for me) that some aquisition magic is going on. Later when I edit the news item (manage_editNewsItem called by manage_editNewsItemForm) there appears an additional catalog entry with the id xxx/content. Now there are two catalog entries for one news item. If I delete the news item manualy using the zope management GUI one of these catalog entries will be deleted only. Hints: 1) The following status message appears in zopes error log after having edited /orgname/news/content/20001219_news000022: 2000-12-19T11:10:41 ERROR(200) Catalog uncatalogObject unsuccessfully attempted to uncatalog an object with a uid of /orgname/content/20001219_news000022. 2) It seems for me that the magic resides in absolute_url(). Does somebody know about a solution of this problem or have an additional hint about generating catalog id's (it's a requirement for me to have the /orgname/-info in the catalog id!)? I'am a Zope newby, so forgive me errors that are obvious. System and SW-Versions: - WinNT4 SP6 US - Zope 2.2.4 started manualy Remark: It's all programmed in Python because I don't like GUI programming tools (click, click, ... :-( ). So I implement all logic in python (as a Product). >>>>>>>>> what I've done in the zope management GUI <<<<<<<<<< Create a news item: http://localhost:8080/up/news/manage_addNewsItemForm View Contents (content folder): http://localhost:8080/up/content/manage_main --> item 20001219_news000022 is listed and links to: --> item 20001219_news000022 is listed and links to: http://localhost:8080/up/content/20001219_news000022/manage_editNewsItemForm View Cataloged Objects (content folder): http://localhost:8080/up/content/manage_catalogView --> content contains 1 record(s). NewsItem /up/news/content/20001219_news000022 (test item) ??? why catalogized with path containing /news/? Edit the item by clicking the link in Cataloged Objects: Edit the item by clicking the link in Cataloged Objects: http://localhost:8080/up/news/content/20001219_news000022/manage_editNewsIte mForm View Catalog Objects: http://localhost:8080/up/content/manage_catalogView --> content contains 2 record(s). NewsItem /up/news/content/20001219_news000022 (test item) NewsItem /up/content/20001219_news000022 (test item edited) ??? why couldn't the old item be uncatalogized? ??? why the changed item is catalogized without /news/ path? !!!

SQL Interface Builder?
by Olaf Zanger 19 Dec '00

19 Dec '00

hi there, i'm working with zope now for a month. i found the znolk product that generates some nice forms and so on. i'm in desperate need for some more functionality though and i'm wondering if anything out there might suit my needs, that are: * customizable with a template or so (without the need to work on the python method as is right now) * edit mode to rearrang things later (now everything has to be done by new each time when the python script gets changed) * report support for more than the standard "select * from xxx" an other question: is there a chance to use the ftp thing with a kio_slave programm from kde? so, has anybody a solution to offer. olaf p.s. i find zope great. -- soli-con Engineering Zanger Dipl.-Ing.

Help save my sanity (DTML-in string comparison)
by Darin Lee 19 Dec '00

19 Dec '00

Zopistas, I am trying to build a simple, 2 tier, tree-style navigation structure for my site. I have puzzled over the following code for hours, and it's just not working right. I have two loops, one that goes through the Parents, and when the parent matches the current folder, I go through the children (There are 2 scripts, one that resides one level up and presents a simple list of objects to click on) The following code lives in the child folders, and displays the parents and all of the HTML documents in the current folder. The output I am looking for resembles below. Item 1 Item 2 Child 1 Child 2 ( if Active document) Child 3 Item 4 Item 5 I can generate the above output, but I would like to bold (add an arrow etc) to the "current" child object. I would also like to skip the object entirely if its ID happoens to be "index.html" This is what I can't get to work, the string compare never works! ―---------------------------------------  <dtml-if "meta_type == 'HTML Document'"> <dtml-call "REQUEST.set('count', 2)"> <dtml-call "REQUEST.set('local_parent', PARENTS[1].id)"> <dtml-else> <dtml-call "REQUEST.set('count', 1)"> <dtml-call "REQUEST.set('local_parent', PARENTS[0].id)"> </dtml-if>  <dtml-if "id == REQUEST['local_parent']"> <a href="<dtml-var absolute_url>" CLASS="navlink"><dtml-var NavName></a> <!-- Here's where it does the string compare and always fails!!!! ―> <dtml-in "objectItems(['HTML Document'])" > <dtml-if "id == local_id"> I Match! <img src="pixel_clear.gif" height="1" width="10"> <A CLASS="navlink" href="<dtml-var absolute_url>"><dtml-var title_or_id><a> <dtml-else> <img src="pixel_clear.gif" height="1" width="10"> <A CLASS="navlink" href="<dtml-var absolute_url>"><dtml-var title_or_id></a> </dtml-if> </dtml-in> <!-- If are not the same, then just put up the link ―> <dtml-else> <a href="<dtml-var absolute_url>" class="navlink"><dtml-var NavName></a> </dtml-if> </dtml-in> ―-------------------------------------------------- BTW, I have tried the NFGNav product, but It doesn't work in my application (I suspect) because I am using transparent folders to organize things. I also want my NAV to start farther down the heirarchy (level 2), not from the root. I would appreciate any help anyone can offer! Thanks in advance, -Darin Lee

newbie permissions
by Max M. Stalnaker 19 Dec '00

19 Dec '00

With some difficulty I got a web site up and it has a form that when submitted writes an object out to a Zcatalog. I am proud of myself. Alas, it asks me for a password when I stroke the submit button. I think I need to set some permissions on the Zcatalog. I need to set them to anonymous. But if so, which permissions?

SiteAccess and Roles
by The Doctor What 19 Dec '00

19 Dec '00

I have site access running, but I apparently don't fully grok roles. I have a directory layout like so: /ZopeRoot /site1 /site2 /site3 /user_acl(2) /user_acl(1) My site access rule is at: http://linuxasm.gerf.org:9673/siteid/view_source All the site[123] directories are SiteRooted and work fine. If I add user as manager to user_acl(1) they have essentially 'root' access. They can do everything. What do I have to do to give site3 to a specific user without giving them access to everyone else? I tried both Owner and Manager roles in user_acl(2) but it doesn't work! What am I doing wrong?
