'System resources exceeded' error with ZODBCDA and Access
by Igor Leturia 07 Mar '02

07 Mar '02

Hi all! I have Zope 2.3.2 installed on a Windows 2000 Server. I have an Access databases and I make queries on it using ZODBCDA. It works fine, but after some time running it gives an error which in English would be (more or less) 'Microsoft ODBC Error. System resources exceeded'. The only way to get it running again is restarting Zope? The database is not very big (about 8000 records). Is it a problem of ZODBCDA, or is it Microsoft's Access ODBC driver's? Do I have to change some parameter (cache, etc.) in any of them? Any help would be appreciated. Thanks in advance, Igor Leturia

ZPT: how to access property sheet of custom ZClass
by David Hart 07 Mar '02

07 Mar '02

Hi! I'm implementing a simple db, using the same methods in the JobBoard example. I looked at Kube, but I'd like something a bit more generic. I'm trying to make add/edit forms and display pages as simple as possible. Rather than have custom versions of all of these, each with copies of the same property names, I'd like to pull the property/attribute names from the property sheet of the ZClass in the Product I added. Something like: <span tal:repeat="props python:root.Control_Panel.Products.CEdb.cedb_record.propertysheets.common.record_default_properties.attrs()"> <p tal:content="props"></p> </span> The above example is probably very wrong for many reasons-- it shows my lack of experience with TAL, python and Zope innards in general -- but I think it conveys what I'm trying to do. I'm not sure if I can use "python:object.attrs()", or even if the objects under Control Panel are accessible to ZPT as the above example produces a guarded_getattr error. Also, is there a more generic or elegant way to refer to the record_default_properties object? Any help would be much appreciated! Regards, Dave

iterate over ZSQL method and make hidden form values...?
by Erik Myllymaki 07 Mar '02

07 Mar '02

I have a form that collects about 15 values, and a ZSQL method that collects about 15 values on the same page. I want to amalgamate them together and push them through to the next page where I could then use them all easily in another ZSQL method by just passing REQUEST. (note, I am using ZODBCDA so zsql_result.dictionaires() is unavailable to me!). Something like this(but that actually works ;-)): <form> <dtml-in zsql_method> <dtml-in sequence-item> <input type="hidden" name="<dtml-var sequence-item-name>" value="<dtml-var sequence-item-value"> > </dtml-in> </dtml-in> <many other inputs here................> <input type="submit" name="submit" value="go"> </form> Thanks, -- -- Erik Myllymaki erik(a)pacific-shores.com

Creates classes available to container but NOT add products menu
by chrisf 07 Mar '02

07 Mar '02

RegisterClass is cool But what if you don't want to register your product. When you create a product and add a ZobjectManager derived Zclass, all subsequent subclasses appear in the subobject menu but not the Products menu. I have a heap of classes. I do not want every class in the add Products menu. I do want them to be available to the top level container class. How do I do this from within python product code. Chris

The MLM, and associated SPAM filtering, is not buggy, but its not perfect either. I have noticed that the amount of SPAM on this list has been decreasing over the last little while, and frankly, I don't think that every item can be zapped, though I expect things will get better over time. The reason SPAM is annoying is the same reason pop-up ads are annoying - they require you to do something in response like close a window or click delete. On a similar note, a request I might have: I use Outlook (not by choice, its our corporate MUA), and every message that I receive from you to the list is posted with a follow-up flag, which I have to subsequently clear with two mouse clicks. I hope I don't cause offense with my request that you might look into having your MUA disable this from its mail headers? Thanks, Sean -----Original Message----- From: Robin S.

(was: [±¤°í]Á¶ÈÀ¯¿µ¾î ¿¥ÇÇ¾²¸®ÇÃ·¹ÀÌ¾î ¹«·áÀÌº¥Æ®!!!) In the light of the amount of SPAM I'm seeing from the Zope lists, I wonder if you've ever tought about, like, doing something about it? Like the magic -x switch to *hint* *hint* ezmlm-make and its good ole mimeremove facility. The Mailman FAQ specifically mentions stripmime and demime. Running reverse DNS lookups on the senders would be kinda kinky, too. And... whatever... :-/ So, dear Listowner, could you PLEASE TURN THIS CRAP OFF? That'd be much appreciated, really. Do I sound bitter? That's because I just found out that this month alone, I've received 1335 pieces of SPAM. And somehow I feel that I don't need dysfunctionally configured MLMs to add to that.

ZClass extensions
by James Gilbert 07 Mar '02

07 Mar '02

Hi all, Here's what I want to do: By selecting a certain class as a base class for a new ZClass (eg MyBaseZClass), I want to have a management tab/page available to the Class definition in the Product where attributes can be added/ edited/deleted (basically access to an object list in MyBaseZClass). These are then created with instances of the ZClasses. Similar to propertysheets, but management of more complex objects than propertysheets provide. What I need is any information on how to define MyBaseZClass so that management tab appears in ZMI and so that properties set there will be created when an instance of the ZClass is created. Indeed, if people think ZClasses are even the way to go. They do provide the desired behaviour - user definition of class attributes via the ZMI which are then available to all instances of that class. Even better would be if there is already a simple solution that I've overlooked :) Any ideas/info/links would be greatly appreciated James Gilbert

Changing ownership...
by Josef Meile 07 Mar '02

07 Mar '02

I'm using the following method to change the ownership of an Object: from AccessControl.Owned import Owned def changeOwner(pObject,pUserFolder,pUsername=''): userObject=pUserFolder.getUser(pUsername).__of__(pUserFolder) pObject.changeOwnership(userObject) Owned.changeOwnership(pObject,userObject,recursive=1) And I call it as follows: <dtml-call "REQUEST.set(objectValue, REQUEST.resolve_url('www.myurl.com/myFolder'))"> <dtml-call "changeOwner(objectValue,acl_users,'tester')"> The above solution changes the ownership of the folder and the objects inside of it (I can see it on the manage interface). My problem now is that I get the following error whenever I try to edit an object that I own: Site Error An error was encountered while publishing this resource. Unauthorized You are not authorized to access indexObject. Why do I get this message if I own the object which I want to modify? It doesn't happen if I create a new object rather than transfer the ownership. What am doing wrong? Thanks in advanced, Josef.
