Zatalog Vocabulary Splitter Update
by Andreas Rippel 26 Mar '02

26 Mar '02

Hi, unfortunately I never found a document explaining the topics "Zatalog Vocabulary Splitter Update" on a larger scale. ISO-8859: I configured the Splitter during installation via the setting the encoding variable in site.py. Does anyone know some cleaner way, e.g. how to set up the catalog parameters? How to do it for windows, because setup.exe starts directly, and there is now way to edit site.py? I have to upload a text or html file as dtml document or methode, otherwise it is not recognized for indexing. How to set up a catalog to index also a plain file? Regards Andreas

ZGDChart - insificient height
by Smith, Neil 26 Mar '02

26 Mar '02

I am using ZGDChart to produce some charts from data from a ZSql method. The SQL method returns a character string for the first field, and a number for the second. I'm having trouble with the length of the character strings. If they get fairly long, 26 characters seems to start the trouble, then I get the message "insificient height" (their spelling, not mine). Increasing the height of the chart sometimes seems to help, but sometimes doesn't, and there doesn't seem to be any simple relation between the length of the strings and the height that the chart needs to be. A chart that is 500 pixels wide and 250 pixels high might accept character strings of 25 characters, but then for 26 characters it could need to be made 800 pixels high.

Changing a COPY of metadata modifies ZClass instance?
by Milos Prudek 26 Mar '02

26 Mar '02

I think I'm going slightly mad :-) A Python Script that is supposed to modify a COPY of metadata in practice changes metadata itself, and ZClass instance :-( for i in context.Catalog_Org(userid=uid): l=i.userid print "title: ",i.title l.remove(uid) When this script runs from ZMI, it changes metadata in Catalog_Org (but index data in Catalog_Org is not changed[!]), and it changes data displayed in ../propertysheets of the given ZClass instances. I believed that "l=i.userid" will put a copy of userid metadata into "l", and that anything I will do with "l" will not influence anything except "l". Why is it behaving like that?

Zope Treasures
by D.Turpie＠open.ac.uk 26 Mar '02

26 Mar '02

Does anyone know what has happened to the Zope Treasures website? http://www.zope-treasures.com/ It doesn't seem to be live anymore or at least I can't get in. I get the "Connection Failed" error and a message saying "The remote host or network may be down". I have had this error message coming up for a while now and just thought I would see if anyone else had the same problems and any idea if they are no longer operating this website. Thanks. David.

Z SQL Bug wasted nearly my whole morning
by Ren Bing 26 Mar '02

26 Mar '02

Dear all: A bug in Z SQL method wasted my whole precious morning! Write the body of a Z SQL method as below, with only Arguments as 'client' insert into test values(client) now goto 'test', input something or not, everytime you get "Error, exceptions.TypeError: __call__() got multiple values for keyword argument 'client' " since the actual case I am debugging is more complex than this, I didn't reach the point at first. I tried my whole precious morning, trying this and that, examine here and there, feeling like jump our of window or smash my computer :-) (not so bad, in face :-) just because that I never expect that the problem exist at the NAME!!!!! at last, nearly tried every thing I can guess (am I too stupid? maybe), I replaced argument name "client" to "clientname" , then everything is fine. Woo, but WHY???? what's inside this? I didn't read this at anywhere. Is there still more like this ahead? May I be so bold to add some comment: when using Zope at first, I am shocked by how easy it is to use, just a few code can do great thing that you need to write several times of codes otherwise, like Java. But more and more, I found that I used several times debugging effort than Java. Perhaps because that I am just new to Zope. But I think the "Zope Book" is not explicit enough, for example, no where mentioned that when you call a DTML method from a python method, you need to pass its container folder or something as parameter, or your DTML method can never find the standard-header...... I spend several hour to find out.... I don't know whether it is my own problem or Zope's problem. But this time, the "client" and "clientname" killed me. I am considering seriously whether or not shall I turn back to Java in next project. Thanks very much. I am not mean to say bad word to Zope. Ren Bing

alternating colors based on sequence-index of outer loop
by John Hunter 25 Mar '02

25 Mar '02

I have a folder called Sections that is filled with Section instances. Each Section contains a variable number of students, and I want all the students in a given section to have the same row color in my table, with sections alternating colors. I have nested dtml-in loops over the sections and students in each section, and want the rows of my table to alternate in batches depending on whether the outer loop is even or odd. Basically, I need to do a dtml-let in the outer loop that the inner loop will access, but am having trouble with the syntax. Here is some example dtml with pseudo code to set the default_color <dtml-in expr="Sections.objectValues('Section')" mapping> <dtml-if sequence-even> default_color="gray" <dtml-else> default_color="white" </dtml-if> <dtml-in expr="_['sequence-item'].objectValues('Student')" mapping> <tr default_color> ..Fill in the row.. </tr> </dtml-in> </dtml-in> Thanks for any help, John Hunter

zope with internet explorer 6--can't narrow workspace
by Joshua Newman 25 Mar '02

25 Mar '02

When I try to edit some dtml for example in the zope management interface, I can't make the frame narrower so I can't see the scroll bar on the text frame. The 'Narrower' button (and the 'Wider' one for that matter) don't work. The 'Taller' and 'Shorter' ones do. Does anyone have an idea about this? Also I think I am having a caching problem as IE 6 remembers pages a little too tenaciously. Is there a way to assure that when I visit a page it will reload it? I've already tried the Temporary Internet file settings (check for new page each time). Could it be a cookie thing? I'm a newbie and not too sure. Thanks Joshua

creating object in local dir from add form in product dir
by John Hunter 25 Mar '02

25 Mar '02

I am developing several ZClasses in a Products dir. I want managers to be able to instantiate some of the ZClasses from the /manage interface and users to be able to instantiate others from a non-manage URL. Users will access http://some.host:8080/path/to/MedBio305 where MedBio305 is an instance of my ZClass Course which has a Method index_html that allows users to view the folder. Within that index_html file, I have some links which point to the add form of a Project ZClass that I want users to be able to instantiate: <a href="/Control_Panel/Products/Course/Project_addForm>upload</a></td> My Project_addForm calls a python script add method. I want that script to instantiate a Project ZClass in /path/to/MedBio305/, but context.Project.createInObjectManager(pid,REQUEST) doesn't work because the /Control_Panel/Products/Course/ dir is the current context for this script. Can someone advise how to create the instance in the MedBio305 dir? I suspect the answer lies in using the BASEn, URLn, special variables of the REQUEST object, but don't know enough about the Zope API to work it out. Thanks, John Hunter
