Re: [Zope] Cloning a ZClass-Instance
by Sven Hohage 13 Nov '00

13 Nov '00

Hallo Chris, my reply is late but the problem is already not solved. I've build a simple ZClass 'News' with base-classes 'ZObject, ZObjectManager'. I haven't changed the permission-settings in the product. The script working on the objects is this: -------------------------- <dtml-in "objectValues(['news'])"> <dtml-let x="_.getitem('sequence-item')"> <dtml- call "manage_clone(x,'test',REQUEST)"> </dtml-let> </dtml-in> -------------------------- The response of Dieter Maurer was, that it is a permission problem -->"Either you are not allowed to call the ZClass constructor at the destination, or you are not allowed to access the object to be cloned at the destination." I'm trying to execute the operation with the role 'manager' That's the traceback: ---------------------- The object holle does not support this operation Traceback (innermost last): File C:\Zop\lib\python\ZPublisher\Publish.py, line 222, in publish_module File C:\Zop\lib\python\ZPublisher\Publish.py, line 187, in publish File C:\Zop\lib\python\Zope\__init__.py, line 221, in zpublisher_exception_hook (Object: ElementWithAttributes) File C:\Zop\lib\python\ZPublisher\Publish.py, line 171, in publish File C:\Zop\lib\python\ZPublisher\mapply.py, line 160, in mapply (Object: NewsPruefer) File C:\Zop\lib\python\ZPublisher\Publish.py, line 112, in call_object (Object: NewsPruefer) File C:\Zop\lib\python\OFS\DTMLMethod.py, line 167, in __call__ (Object: NewsPruefer) File C:\Zop\lib\python\DocumentTemplate\DT_String.py, line 502, in __call__ (Object: NewsPruefer) File C:\Zop\lib\python\DocumentTemplate\DT_In.py, line 607, in renderwob (Object: objectValues(['news'])) File C:\Zop\lib\python\DocumentTemplate\DT_Let.py, line 147, in render (Object: x="_.getitem('sequence-item')") File C:\Zop\lib\python\DocumentTemplate\DT_Util.py, line 337, in eval (Object: manage_clone(x,'versuch',REQUEST)) (Info: REQUEST) File <string>, line 0, in ?

Newbie question(s)
by Bowyer, Alex 13 Nov '00

13 Nov '00

Hi, I have what I'm sure is a very simple question about Zope programming style: I want to count how many objects are contained in the current container object and then do something with that value, but I can't do the bit I need to do at the point of reading the count variable because I am in the wrong namespace. I can't begin a dtml-let because I would need to close dtml-if before dtml-let, which is not allowed. <dtml-in objectValues> <dtml-if sequence-end> <dtml-var count-id>  </dtml-if> </dtml-in>  What is the "accepted" way of passing a value into a different scope? Do I have do a REQUEST.set or is there a tidier way? Also I think I read somewhere that you can use the object.subobject or object.property syntax but I never got that to work, what's the catch? One last thing, I sent a couple of mails to the list about problems I had with manage_delObjects. I still haven't got it to work. Since the best way to learn Zope is by example, I wonder if anyone could direct me to a sample piece of code where a container of some sort deletes one of its children subobjects?

LDAP variable problem 'title'
by Michael Blewett 13 Nov '00

13 Nov '00

Hi Zopistas, Firstly, a big thank you to all thos epeople who helped me with KeyError problem when accessing LDAP entries. Just so the solution makes it onto the mailing list archive (for the next bunny who has the same problem) the solution was to add the following to each of your variables missing=  ...so that when Zope came across entries without that attribute it didn't barf. I now have one last problem. I can now access all entries from the LDAP directory using the notation <dtml-var sn missing =  >- all except one - the "title" attibute . I am guessing that it is because Zope uses "title" to reference the title of the object in the zope database, and therefore won't let you get at the ldap variable using the normal: <dtml-var title> notation. Is there any way I can pinpoint the LDAP variable instead of the object title in zope? I have no control over the ldap server and attributes name, so I can't change it at that end. When I test the LDAP filter method I can see the variable (it lists all of the attributes of the LDAP record), but I can't reference it in DTML. My filter method is called 'Academics' and just extracts a list of academics in the biology department here at Monash University. I'm sure there must be a way using python notation, but not being a python expert (yet!), I could do with a few clues... Any ideas? Thanks again... - Michael ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Michael Blewett Computer Support Mgr - Biological Sciences Monash University (Clayton Campus) Victoria Australia 3168 "I'm out of my mind at the moment, but feel free to leave a message..."

Does anybody work on a database adapter for SAP DB?
by Joachim Werner 13 Nov '00

13 Nov '00

Hello! I'd like to know if anybody is working on a database adapter for the SAP DB. Some background info: The SAP DB is a version of Adabas D that was bought by SAP for use with their enterprise software R/3 a couple of years ago. It's an enterprise-level, fast relational database with transaction support, stored procedures, subselects, and the like. And: It's under the GPL now! The binaries are up already on http://www.sabdb.org - source is going to be published soon. SAP provides three Python modules to - access the database using SQL - manage the database - manage the replication manager of the DB That means building a DA should be straightforward (I just don't know if the modules are threadsafe already ...). Any feedback welcome ...

My query is really more general though, that was just an example, I need to know what the generally accepted method is for transferring values through the code (i.e between namespaces) IMHO as far as Zope documentation goes, the thing that is really lacking is a document introducing people to how to program in Zope, explaining the overlaps between Python and Zope/DTML and explaining the different syntaxes for calling variables, methods etc? There are a lot of references on specific functions, methods etc but no general overview. Maybe the forthcoming Zope book will address this better. I am also still looking for example code using manage_delObjects.

Forcing Content-Type of Image object
by Peter Bengtsson 12 Nov '00

12 Nov '00

I don't want Zope to find out what content type an Image has. I want to be able to force that programmatically myself from DTML. Here are some code examples that doesn't work: <dtml-call "PARENTS[0].manage_addImage('awapimage.wbmp',file,'Give it a Title','','image/vnd.wap.wbmp')"> <dtml-call "PARENTS[0].manage_addImage('awapimage.wbmp',file,'Give it a Title','image/vnd.wap.wbmp','image/vnd.wap.wbmp')"> <dtml-call "PARENTS[0].manage_addImage('awapimage.wbmp',file,'Give it a Title','image/vnd.wap.wbmp','')"> Image.py contains this: def manage_addImage(self, id, file, title='', precondition='', content_type='',REQUEST=None): I have searched the mailing list and looked at Image.py but can't find it. Help, please Best regards, Peter

They allow you to "mount" FTP hierarchies into your local file system and work with the files as though there were local files. Dieter
