RE: [Zope] geting the type of an object from within dtml ??? ==> it works
by NABETH Thierry 26 Jun '00

26 Jun '00

Hello, >> <dtml-var "meta_type"> works. Yes, it display the correct meta type. Thanks. When I had done some tests, I forgot to set the meta_type field, and the system was displaying the meta type of the superclass instead. (which had confused me). Note: I am still not very confortable to use the "meta_type" field to get the class name, and would rather have prefered to have the real class itself. (python type function). Thank you again for your help.

RE: [Zope] getting the type of an object from within dtml ???
by NABETH Thierry 26 Jun '00

Hello, >> would you please elaborate.... what are you trying to determine the type of? Sorry for my lack of clarity. I would like to get the class of the object, just using dtml. (and without using external method) Typically, the idea would be to define a dtml method (for instance getclass) that return the class of the object, so that I could write: --- in a dtml-method defined for a Class A, and that can be called from instance of class A or subclasses of A. ... <br>My class is :<dtml-var getclass> ... >> Zope namespace ... eventually the namespace will be explained and documented better. I believe this is not a matter of documentation. It is just that is is uselessly too complicate. Note: I very much like some of the ideas behind Zope. (such as the good integration of an OO database in the system, use of a dynamic language, etc.) But I can really not get used to some of the other aspects that are very well addressed by other systems, but are so poorly addressed by Zope such as: * the namespace. * bad integration with python. * can not change the inheritance tree once a class has been created. (I have tried one of the trick that was posted somewhere, but it does not work 100%). * very bad support for pointers (object1 --> object2).

I agree. _[_['blah']] is probably the nastiest thing I've ever seen. and then someone will start adding lambdas to it and it will be all crap to maintain from there... :( eventually the namespace will be explained and documented better, this is mainly a python/ZOPE framework idea that needs to be experienced.

Unique Identifiers for Zope Objects
by Michael Abbott 26 Jun '00

26 Jun '00

I'm looking for an internal globally unique identifier for objects in my Zope store. I know that I can use id=object.absolute_url() to create an identifier and then <something>.resolve_url(id) to recover the object from the identifier -- but I have two problems with this API: 1. The URL is not really a global identifier, as resolving it seems to depend on the <something> from which I call resolve_url(). In particular, if the id is created when Zope is running normally (as a service), and resolved when running Zope from the command line debugger, the resolve fails. This is not good. 2. The need to locate an object <something> carrying the resolve_url() function is a problem; in particular, I would find it helpful if I could resolve my global identifier from within a __setstate__() method (where I have no access to local Zope variables), so I really want a genuinely global function for resolving my id. Any suggestions, or do I have to dig into the (disagreeable and uncommented) bowels of Zope and write my own? (If this is on the wrong list, please point me to the right one. Thanks.)

Problem with the datatype "lines"
by Anders Holmbech Nielsen 26 Jun '00

26 Jun '00

Hi Zopers, I have found out that when using the datatype "lines" in my own ZClass it won't obey to the locale settings. That means that the words coming from "lines" look like: t/370nk. And therefore they don't get correctly indexed in the database. I'm running Zope 2.1.6 (on both linux and winnt 4.0). Is there an update to this problem or a workaround ?

2.2.0b2 and ZSQL method and Zcatalog
by Bak ＠ kedai 26 Jun '00

26 Jun '00

hi all, i've upgraded my site to 2.2.0b2. done light testing. here's what don't work -ZSQL method. got len() of unsized object. T.J. Mannos (http://zope.nipltd.com/public/lists/zope-archive.nsf/242bb7cc2b2c343d802568…) mentioned that we need to recreate the SQL method from scratch. is there any other ways? anybody else with this problem? also tried deleting, renaming the ZSQL method, but got the same error with this trace back. FYI, the ZSQL method icon is a folder instead of that green object.

Zope 2.2b2 security conundrum

How is the new security model supposed to work with ZClasses and how do I get round this problem so I can give a user the ability to add a new object.

geting the type of an object from within dtml ???
by Thierry Nabeth 26 Jun '00

26 Jun '00

Hello, I have unsuccessifully been trying to figure out ou to get the type of an object from withing html. for instance: <dtml-var meta_type> does not return the correct type. Python is supposed to have a function type(object) that return the type, but I was not able to find a way to call it. (and I would rather prefere not to have to define an external function.). My problem seems to have to do with the Zope namespace (which model I believe is a real pain in the ass :-((((). Any suggestion, ideas ? Thanks Thierry Nabeth, INSEAD CALT http://www.insead.fr/CALT/
