Copy and paste is not working in custom folder product
by Martijn Faassen 26 Nov '99

26 Nov '99

Hi there, I've created a custom folder which has some addable products defined inside it. When I add such a product and try to copy and paste it, I get this traceback: The object test does not support this operation Traceback (innermost last): File /home/zope/lib/python/ZPublisher/Publish.py, line 214, in publish_module File /home/zope/lib/python/ZPublisher/Publish.py, line 179, in publish File /home/zope/lib/python/Zope/__init__.py, line 201, in zpublisher_exception_hook File /home/zope/lib/python/ZPublisher/Publish.py, line 165, in publish File /home/zope/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: manage_pasteObjects) File /home/zope/lib/python/ZPublisher/Publish.py, line 102, in call_object (Object: manage_pasteObjects) File /home/zope/lib/python/OFS/CopySupport.py, line 199, in manage_pasteObjects File /home/zope/lib/python/OFS/CopySupport.py, line 374, in _verifyObjectPaste Copy Error: (see above) The folderish product derives from ObjectManager. The addable products derive from OFS.SimpleItem.Item, Persistent, Acquisition.Implicit, AccessControl.Role.RoleManager Note that these addable products do have an extra object set inside them. Should this one somehow define copysupport as well? Anybody have any clue why copy and paste is not working? What should I investigate? If this post contains too little information I'll just release my code with this bug next week so people can study it then. :) Regards, Martijn

type() in DTML or/and in Python Method?
by Ava 25 Nov '99

25 Nov '99

Hello, I wonder why the builtin function type() is not available, neither from DTML nor from products like PythonMethod ? Could the use of such a function be a security problem? For example, it is impossible to know if a variable holds a list or a tuple or a string from DTML. I wrote a PythonMethod to do just that: ---------8<---------- return type(value)==type([]) ---------8<---------- But that didn't work either. So I ended up writing this PythonMethod: ---------8<---------- try: value+[] # if it throws an exception, value is not of type 'list' except: return 0 return 1 ---------8<---------- Sometimes, it is not desirable to write an external method, and in such circumstances, one feel like doing simple things in a simple manner... :-) note that i am mostly interested by the security implication caused by the use of the type function. Solving my "problem" is not important right now. Regards, Jephte CLAIN minf7(a)educ.univ-reunion.fr PS: please post any answer to minf7(a)educ.univ-reunion.fr instead of ava(a)dde974.equipement.gouv.fr Also, I'm not on the list yet, so if you could cc me any answer...

deleting standard_html_header
by Thilo Mezger 25 Nov '99

25 Nov '99

hi, does anybody know why i can't delete standard_html_{header,footer,error} ? i get an error message "standard_html_header does not support this action" or something. i suppose that this object is somehow "protected" so that i can't delete it because it is vitally important to the system. any idea how i could remove this delete protection? thilo -- mezger(a)innominate.de innominate AG networking people fon: +49.30.308806-11 fax: -77 web: http://innominate.de pgp: /pgp/tm

Calling DTML methods from Python
by Itamar Shtull-Trauring 25 Nov '99

25 Nov '99

I want to run manage_tabs from a PythonMethod. So I do request = self.manage_tabs(_.None, _) but now manage_tabs doesn't know who filtered_manage_tabs is. So how do I call a dtml method so that it knows where it is and works correctly? -- Itamar S.T. itamars(a)ibm.net

I think what your looking for is the containment path of the object, not the acquisition path. If you use acquisition, you'll have to deal with the fact that the objects 'path' depends on how it is acquired. In your example, if gee/index_html called my_method, then its aq_parent is 'gee' not 'bar'. This is the correct behavior. If you want to find an objects *containment* parent, then you have to do 'object.aq_inner.aq_parent'. You cannot get 'aq_inner' from DTML, I can't think of any good reason why not, but security would have to be carefully thought out. -Michel

See the post I made yesterday - snapshots of mozilla since a few days ago have a fix for this. Without this fix, the zope mgmt interface is not usable.

Getting a list of ZCatalogish objects
by Alexandre Ratti 24 Nov '99

24 Nov '99

Hello, How could I retrieve a list of available ZCatalogish objects? I meant objects in which CatalogAware objects can register themselves. This include ZCatalogs but also custom objects based on ZCatalog. The nearest solution I've found yet is using ZQueryIds(). This method returns ids of searchable objects, which isn't exactly what I'm looking for (Z SQL methods are searchable, aren't they?). Thanks. Alexandre
