Newbie: ZClasses
by rra42 14 Aug '02

14 Aug '02

I have begun creating some products based on ZClasses. Can anyone tell me how I can programmatically create new instances of these products and add them to a folder, rather than create them one by one via the TTW interface? Thank you for any help received. Rob ________________________________________________________________________ Want to sell your car? advertise on Yahoo Autos Classifieds.

ZODB performance issues
by VanL 14 Aug '02

14 Aug '02

Hello, We have a script that does a'database import' into the ZODB. This script iterates through a series of records (currently in text files) and creates corresponding Zope objects. We can do small (<100) imports relatively well, but on a large import (1000+) the Zope process balloons in size and eventually becomes unresponsive. Sending a SIGHUP to Zope restores normal functionality and performance, and the created objects all seem to work fine. However, we don't want to have to restart Zope every time we do an import. My suspicion, based on the above evidence, is that the ZODB caching mechanism is to blame for the slowdown. Can anybody confirm this, or offer an alternate explanation? And, if caching is the culprit, is there a way to programmatically turn off caching for the duration of a script run? Thanks, VanL

Re: [Zope] Help!!!

I too am experiencing the same roadblock. The product is quite simple - I have one class, and it derives from CatalogAware and ObjectManager. It has a few string properties, and a view. If I try to create an object in the same folder as the product, it works. The same user, however, cannot create the object in a different part of the folder hierarchy. Where would I look to check "Create ZClass Instance" permissions? Or perhaps you have solved this problem already?

Everything seems to be fine. You are sure, your ZClass is named "tbContainer"? You are sure, the "Create ZClass instance" permission is mapped to some permission, the current user has? When you like (and your Product does not reference non-core Zope products), you can export the product and send me the result (zip'ed or gzip'ed please). I will try to find out what happens.

zpt vhm bug: here?
by Mark McEahern 14 Aug '02

14 Aug '02

If I'm using a whole page macro, here seems to refer to the object containing the macro rather than the object using the macro. If I'm trying to construct a <title/>, I'd like to do something like this: $site : $page E.g., foo.com : about But if I do this: <title tal:content="python:'%s : %s' % (container.title_or_id(), here.title_or_id())"></title> both of these resolve to---oops, now I suspect I've found a bug. Both of them resolve to the title or id of the Root folder. I wonder if this is because I'm using a VirtualHostMonster? /Root (title: foo.com) master_html index_html In the above scenario, I get <title>foo.com : foo.com</title>. // mark -

ZSQL field problem
by Colin Fox 13 Aug '02

13 Aug '02

Hi, All. I have a form that allows a user to edit a table with a date field. The user should be able to 'null' the date field. I'm using a ZSql method similar to this (very simplified): update sometable set (birthday = <dtml-sqlvar birthday type="string">) where username = 'someuser'; If the user cleared the text input field for the birthday, I'd like to have it say: set birthday = null where username = 'someuser'; But all I get is: set birthday = 'None' where username = 'someuser'; Any suggestions?

new External Methods not recognized
by Richard Deeley 13 Aug '02

13 Aug '02

Summary: Cannot access new External Methods, olds ones OK. (Zope 2.5.1 (binary release, python 2.1, win32-x86), python 2.1.3, win32) Problem: I have tried correlating this any way I can, but it still doesn't make sense. I can redefine the old methods to use new functions. I can create and test new External Methods. What I can't do is call any methods from DTML using newly created ExternalMethods. This generates a name error. There is only one user to the system (me) and no changes that I know of have been made to any security aspects. Other: So fundamentally, even though the External Method is created OK (the process says everything went fine), it doesn't make it to a point that DTML will recognize it. I can point the old ones (ExternalMethods) to any function I want and they will work. The only thing (more likely a red herring) I can think of that happened was adding the XML module (the images are missing in the docs, btw). Other than that, can't think of anything that changed. I re-read the docs and hunted around the Web and haven't found a solution there yet. I tried comparing all the properties and anything else I could find between the old and new ones. Didn't find anything. I have tried shutting down and restarting the server and even the PC. Any help as to how to go about getting new methods accepted are appreciated. (pls reply to this address is needed as I am not on any mailing list). Thanks. __________________________________________________ Do You Yahoo!?

Zope documentation and HOWTOs

A while ago, I wrote an index to the HOWTOs - it's not automated, so it hasn't been updated for a while. It is much more accessible than the One Big List though (well, it is for me :) http://www.zope.org/Members/richard/howto_index I'm going to see about updating it Real Soon. Richard
