Acquiring permissions on cataloged objects
by Wilbert Kraan 22 Sep '03

22 Sep '03

In a product I'm making, privileged and unprivileged users can query a ZCatalog that indexes both restricted and unrestricted objects. So I'd like to filter out restricted objects from catalog returns for the unprivileged users. Here's what I tried: 1. Give objects an extra property at creation time that indicates the crucial permission (role: Anonymous, permission: View). Doesn't work because the objects are nested, and have to acquire permissions from their parents. 2. Somehow get SecurityCheckPermission to loop over the 'real' objects and block rendering of the corresponding result object. Something like this: <dtml-in expr="TheCatalog({'meta_type':'TheObject'})"> <dtml-if expr="_.SecurityCheckPermission( 'View', object"> <dtml-var title> </dtml-if> </dtml-in> This should work if only I could get anything out of the record object that allows me to reliably acquire the 'real' object. I.e. I don't know how to fill in the "object" in the code above. Most promising is running the getPath() method on the result object, but I haven't managed to coerce its result into something SecurityCheckPermission can work with. 3. Following Juri Pakaste's blog post <http://www.helsinki.fi/~pakaste/blog/ugly_zope_hacks.html>, I realised that even testing permissions on remote objects needed the 'View' permission, so I tried something like this: <dtml-in expr="TheCatalog({'meta_type':'TheObject'})"> <dtml-try> <dtml-call "_.int(getPath)"> <dtml-var title> </dtml-try> </dtml-in> Same problem: how do I get anything in that <dtml-try> block to access the actual object? <dtml-call "_.int(getPath)"> and (very, very) numerous variations don't work. The site is Zope 2.5.1, the Zcatalog is indexed automagically. -- Wilbert Kraan Web Journalist Centre For Educational Technology Interoperability Standards (CETIS) +44 (0)1248 383645 web: http://www.cetis.ac.uk newsfeed: http://www.cetis.ac.uk/news.xml

people structuring
by Roman Bogoyev 22 Sep '03

22 Sep '03

Hello, Being new to zope, I'm having trouble wrapping my brain around how to structure people objects in our dept. Perhaps this is a common modelling problem which someone has done before: We have people, and people may have many different roles. So for example, a person can be a lecturer and also a fire warden. Now each person has common properties, and then more specific ones as a lecturer or fire warden. So I create a container for common persons, and then containers for lecturers and containers for fire wardens. Each is its own class, with its own properties. Now with my brain still full of relational data base concepts, I use each object's id as a key, so to look up lecturer Joe's telephone number, I say in the context of lecturer, joe.people.joe.telephone which is very ugly and path dependent.... furthermore, if Joe the lecturer has a specific phone number then I want that, not Joe the person's number. Another way could be to have a getTelephone() method and use aquisition, but again, that would be structure dependent - all lecturers and firewardens would have to live in containers within the People container. So can an object 'inherit/acquire' another object's properties without that object being a subclass of the other? Should I forget this altogether and use ZCatalogues? Is there something really obvious staring me in the face? Thanks for any pointers.

Opening topic crashes zdaemon
by Art Zemon 22 Sep '03

22 Sep '03

Hello, I have installed Zope & CMF on a FreeBSD virtual private server. It seems to mostly work but some things cause Zope to crash. E.g., 2003-09-21T10:58:40 ERROR(200) zdaemon Process 51333 terminated by signal SIGSEGV(11) and 2003-09-21T11:06:47 ERROR(200) zdaemon Process 54714 terminated by signal SIGBUS(10) These were called when I tried to simply open a topic that I created, but have been unable to do anything with because the daemon keeps crashing. I installed everything from ports, including Python 2.1 (and it has the stack size patch) * Zope version: (Zope 2.6.1 (source release, python 2.1, linux2), python 2.1.3, freebsd4) * Python version: 2.1.3 (#1, Sep 21 2003, 10:51:54) [GCC 2.95.4 20020320 [FreeBSD]] * System Platform: freebsd4 from the products list: * CMFCalendar (Installed product CMFCalendar (CMF-1.4)) * CMFCore (Installed product CMFCore (CMF-1.4)) * CMFDefault (Installed product CMFDefault (CMF-1.4)) I tried using Plone and gave up because it was crashing the daemon, too. Ideas???

Perhaps Dyaln is right, you should try the javascript first on a normal html page and see if it works. If it doesn't, then the problem is in your javascript. If everything works, try the dtml method and see if the html source that it generates is the same as the html page. If they are different, then you are doing something wrong in your dtml method or in the dtml methods that you call. Regards, Josef

[Ann] ManagableIndex: combine value, control acquisition, check types
by Dieter Maurer 21 Sep '03

21 Sep '03

ManagableIndex can mean different things for different people. For a content manager, it brings flexible field and keyword indexes managable via the ZMI to * combine values from different sources, ignoring irrelevant values and transforming values in an inadequate form, Example: index an object via title if it is non-empty but use id otherwise Example: add portal_type to the Subject index transforming it into a sequence (as required by a keyword index). * control acquisition and prevent acquired values to be indexed * ignore stop-terms, normalize terms and check types Example: when you do not want that an object is indexed under a meaningless default value, you can define this value as a stop-term Example: the BTrees underlying Zope indexes require its keys to have a persistently consistent ordering. When this is not the case, they become corrupt. While modern Python versions (at least Python 2.3) compare values from different elementary types persistently consistent, the result can be quite unintuitive. Therefore, it is best when all terms in an index belong to the same types. Normalizing and type checking helps to ensure this. For a developer, ManagableIndex provides a framework for index definition, improving on PluginIndexes. It provides for managability, automatically and intelligently handles unindexing when an object is reindexed and implements and, or and range queries (for not too complex indexes). ManagableIndex requires OFolder.
