dtml-calendar question
by Marc DANAI 03 Apr '00

03 Apr '00

Hi, Is it possible to use dtml-calendar per user? or it is only global calendar shared by evry body? If yes, I saw the simple example from Zope site when downloading the product but I can figure out where I have to put username in order to find specific user information. Thank's -- marc __________________________________________________ Do You Yahoo!? Talk to your friends online with Yahoo! Messenger. http://im.yahoo.com

I've deleted Zope MySQL Database Adapter 1.1.4 & 2.0.0 from lib/python/products/ and all connections I had on the site's folder! This is equal to say that i started MySQLda 2.0.0 all over again from 0. Then I installed MySQLda 2.0.0 from the beginning and... PROBLEM!!! Nothing new in the products list/dropdown list. Seems like MySQLda 2.0.0 should be fully tested on both platforms (Linux/NT) before public release, don't you think? thanks --- Hugo Ramos - hramos(a)ruido-visual.pt Ruido Visual, Lda

FSSession and _v_data
by Marc DANAI 03 Apr '00

03 Apr '00

Hi, I have a strange PB with FSSession and I can't understant why to resolve it. I use <dtml-call FSSession> in each page under my site tree but time by time I get an error messages with Zope concerning _v_data. Sometimes If I reload the page the PB gone and sometimes none. Even if variable is not set I must get 'None' when I try to find it? Here is an example of error: File /home/dm/Zope-2.1.3-src/lib/python/DocumentTemplate/DT_String.py, line 502, in __call__ (Object: index_html) File /home/dm/Zope-2.1.3-src/lib/python/DocumentTemplate/DT_Util.py, line 335, in eval (Object: _.str(FSSession['bgcolor'])) (Info: FSSession) File <string>, line 0, in ? File /home/dm/Zope-2.1.3-src/lib/python/DocumentTemplate/DT_Util.py, line 161, in careful_getitem File /home/dm/Zope-2.1.3-src/lib/python/Products/FSSession/FSSession.py, line 224, in __getitem__ (Object: FSSession) In this example, it is about bgcolor but sometimes about other variables. Any suggestion ? Thank's __________________________________________________ Do You Yahoo!? Talk to your friends online with Yahoo! Messenger. http://im.yahoo.com

Storing an object in RAM during Zope's up-time
by Hung Jung Lu 03 Apr '00

03 Apr '00

Hi, How do I store an object in RAM during Zope's up-time? I don't want to store it as a persistent object. And I don't want it to disappear after a http transaction (so REQUEST variable is no good.) I would like to be able to create this object given a particular http transaction, and afterward I may want to modify it. This is a bit like session management data, but it's a piece of data that is shared by all sessions... regards, Hung Jung ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

Well, I just moved my zope to a Solaris box rebuilt with gcc. I'm now able to CONSISTENTLY get this thing to crash. What i do is point a couple of wgets at the box to recursively snarf up pages. This doesn't seem to cause any problems (yet) Then with my browser, I try and load up some pages. Usually, within four or five attempts at loading pages, BAMM zope starts eating up CPU cycles and within two minutes zope crashes... And this is what the debugger tells me: Program received signal SIGSEGV, Segmentation fault.

I'm using Zope 2.1.6 on NT and I've tryed the normal procedure of stoping the Zope Service, replacing the ZMySQLDA dir under /zopedir/lib/python/products/ and restarting the Zope service again... 2 things happen at this point: - older database connections brake - i don't get the Z MySQL database connection in the dropdown list here's the message i get when i click on an old MySQL database connection: This object is broken because the ZMySQLDA product that created it is no longer installed or is installed incorrectly. Please contact your product vendor for assistance. Note that the data associated with this product has not been lost, and will be accessible again if the product is reinstalled. any help available??? thanks --- Hugo Ramos - hramos(a)ruido-visual.pt Ruido Visual, Lda

finding the type of an object
by Allen Wallis 03 Apr '00

03 Apr '00

Hi, I need to test the type of an object for the following reason: I have a form, one of the inputs being a <SELECT NAME="name" MULTIPLE> etc. Now, when there are more than one item selected in this <SELECT> list, then the variable <dtml-var name> is a list (think) which can be used in a <dtml-in name> </dtml-in> iteration. The problem is if the user selects one item, then the variable "name" is a string, containing the one item that was selected. The problem is that if one simply does a <dtml-in name> iteration without checking the type of the variable "name", then the method will fail when the user only selects one item from the list. Hence I need to know the type of the variable "name". How do I find this out? Is it possible to call the python function type() from within a dtml method? If not, how else does one handle this situation? thanks Allen
