help a zope newbie
by Amit Redij 26 Jun '00

26 Jun '00

Hello I want to know more about Zope. I have seen few site powered by Zope. One thing I had noticed is that almost all of those sites are mostly static pages. I mean I am interested to see how can Zope be used for a portal. like containing many pages having lots of form variables. database connectivity etc. what is the performance then. can anybody help me evaluating this. thanks in advance.

I am running SiteAccess on two 2.1.6 installs -- one on a RedHat 6.1 box and the other on a RH6.2 box. Both work like a champ. These were both fresh 2.1.6 installs. Does the problem typically occur w/upgrades or did I just get lucky twice? I ask because I have a 2.1.4 install that I've been planning to upgrade -- and it serves several domains and depends heavily upon SiteAccess. > Oleg.

Worldpilot record problem with restarting Zope
by ADG 26 Jun '00

26 Jun '00

Hi all, I have a problem with my worldpilot, I found the worldpilot cannot remove any deleted record after the ZOPE is restarted I have setup my worldpilot and zope in my NT4.0 server successfully, and I can create and delete my record successfully as well, but after I restart the ZOPE, all the removed records are back in again. This creating some problems here, (1) It cannot REALLY remove the records, (2) I cannot restart my ZOPE, (3) If the record cannot remove, then the database will become too large... Can anyone help me one that Thank ADG

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 ?

MySQLDA Problems with simple constant/function queries
by Stefan Franke 26 Jun '00

26 Jun '00

I'm using MySQLDA 1.1.3 on Win32. When I type the following queries into the test tab edit box, I get the traceback below: select LAST_INSERT_ID() or select 1 from <table> Of course "select * from <table>" works. When I look into db.py, the error doesn't look very hard to fix, I think I'll give tomorrow. Is there some API documentation of what a DA is supposed to do? Since the 1.1.4 query() code is identical, I think the problem appears there as well. Please reply to the posting via email directly, since I'm not subscribed to the list.

Zope 2.2.0b2 - Undo
by Oleg Broytmann 26 Jun '00

Hi! Do I understand it right, that on every object Undo displays only those action that applied to that object? And all Undo action are listed only in root? (that's looks pretty good for me!) Oleg.

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).

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.)
