access to DTML's quoting and formatting (was: [Zope] ID = "somebody@someserver.com"... ?) (was: [Zope] ID = "somebody@someserver.com"... ?)

Unfortunately, it does not. You can emulate it with specialized DTML methods. As an example: "url_quote": Define the DTML method: url_quote as: <dtml-var text url_quote> Ensure, there is no whitespace whatsoever before '<' or after '>'! You call this function with: url_quote(text=<your_text>) > <dtml-call "REQUEST.set('firstname', firstnam)"> > <dtml-call "REQUEST.set('surname', surnam)"> Get rid of these by using the correct name in the first place! > <dtml-call "REQUEST.set('email', eadr)"> <dtml-call "REQUEST.set('email', url_quote(text=eadr))"> > ... As someone else already pointed out, you can use "_.string.replace(eadr,'@','_')" if only the '@' makes problems. But email addresses may contain other funny characters not allowed in id's. Therefore, "url_quote" is safer (but not completely safe -> '/'). Dieter

Either one of the objects does not want to be accessed or there is one that can be accessed but does not provide access to "id". In the first case, you could add the argument "skip_unauthorized" to the "dtml-in" tag. This would simply skip the objects you should not see (quite nice). The second case is a bit more difficult. You would either need to allow "id" access (i.e. 'View') for "Annonymous" (for the refusing object) or give your method a proxy role with appropriate privileges. For your simple example, however, you can recode to avoid these troubles: <dtml-in objectIds> <li><dtml-var sequence-item> </dtml-in> Dieter

In which respect does it not work in lower level folders? Exceptions, does not unfold, seems to be empty, ...?

Re: [Zope] Cloning a ZClass-Instance
by Sven Hohage 09 Nov '00

Once again thanks to you, but I can't figure out why cloning it's not possible. The object is a simple zclass with the baseclasses ->ZObject, ZObjectManager<- Nothing special. I know that cloning a catalogaware zclass it's not working but object-manager?? That's the complete traceback: ------> 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 ?

Hi, Has anyone used this before? I am a newbie and would like to play around with it. I have the how-to docs. But my problem starts at the download! When I try to open it with winzip I get this error: �Error reading header after processing 0 entries�. I have successfully untared other files with winzip. I have dowmloaded it 4 times to make sure it wasn�t just corrupted. Is there another place that I can download it? Also any tips on install/use are welcomed! Thank you. ===== Kathy Hester to feel powerful often to act powerful sometimes to overpower others seldom to share power whenever possible - unknown __________________________________________________ Do You Yahoo!?

ZCatalog Range Weirdness
by Jeff Hoffman 09 Nov '00

09 Nov '00

Hello, We have an interesting situation, here, and I can't seem to put my finger on what's going on. Let's say I have two different classes of objects being cataloged. The first class, Class A, has a floating point attribute myFloat. The second class, Class B, does not. 'myFloat' is an index in the Catalog. Let's say the makeup of class instances in the catalog is 50/50 Class A and Class B: Instance1 (Class A): myFloat = 0.5 Instance2 (Class B) Instance3 (Class A): myFloat = 0.65 Instance4 (Class B) Instance5 (Class A): myFloat = 0.55 Instance6 (Class B) I queried the catalog with: Catalog(myFloat=0.0, myFloat_usage='range:min') Expecting to get record objects representing: Instance1 (Class A): myFloat = 0.5 Instance3 (Class A): myFloat = 0.65 Instance5 (Class A): myFloat = 0.55 Since objects of Class B do not have myFloat, and would not be included in the myFloat index. Instead, I get: Instance1 (Class A): myFloat = 0.5 Instance2 (Class B) Instance3 (Class A): myFloat = 0.65 Instance4 (Class B) Instance5 (Class A): myFloat = 0.55 Instance6 (Class B) In other words, I get all objects back, whether they have a myFloat attribute or not. Interestingly, if I change the query to: Catalog(myFloat=0.5, myFloat_usage='range:min') I get the expected results. Using 0.1, 0.2, 0.3, or 0.4 does not work; 0.5 seems to be the magic number, which I find curious given that 0.5 is the minimum value present in any of the instances of Class A. Can anyone shed some light on what's going on, here? How do I ask the Catalog to return all instances who have a value, any value, for myFloat, but none others? Thanks in advance, --Jeff --- Jeff K.

RE: [Zope] FW: [Zope] adding properties to all existing docs
by michael angelo ruberto 09 Nov '00

However, I would not make such changes asynchronously. I would use "ZopeFind" to locate all objects that need to be updated and then do it. Maybe, its a matter of personal taste ... Dieter this is an interesting idea. another thing i might try is running the script from Xron and ZopeFinding the objects. in this way the task is completely automated and will free me from having to run it whenever new objects are added. -<mike>-

For the past hour and a half I have only once been able to get through to zope.org. lists.zope.org/mailman/listinfo is accessible, however. A zope.org-status mailing list might be helpful, like the egroups-status list, since Zope work is so dependent on the site. I've been trying to read product descriptions. Is that information available anywhere else? Second, I thought there was a searchable archive of the zope mailing lists. I just found it in my bookmarks: http://zope.nipltd.com/public/lists.html but I was not able to find this link on the lists.zope.org url referenced in the mailing list digests... the list manager might want to change that. Third, I'm trying to figure out ways of managing/developing with Zope from a unix console, using text editors, text browsers and so on. I have no doubt that others would rather not have to use a mouse and GUI to work with Zope. I have already found http://www.zope.org/Members/sf/zopeshell But it says it does not work for 2.2 Could someone please point me to documentation about console-based zope management? If it's easy to find on the zope site, I will find it when I can get through again. thanks, Colin
