LOL Jérôme , Thats a great spin on it, I like it.

That would mean that every single film from the netherlands is about people suing each other but that you never actually see them doing it. :-) Not cross-posting to zope(a)zope.org because this is as off-topic as it gets.

ObjectManager problem
by Max Møller Rasmussen 31 May '01

31 May '01

I am making a product that draws a graph in PIL and then saves the image as a GIF in a Zope ObjectManager. If the image doesn't exist it will be rendered and saved in the objectManager. When I run it the first time the image renders just nicely in a dmtl page. If I try to reload it, I get an error that says:: Error Type: Bad Request Error Value: The id "laeringsGraf" is invalid--it is already in use. ... File C:\zope23\lib\python\Products\ots_laering\ots_laeringLogic.py, line 207, in updateGraph (Object: laering) File C:\zope23\lib\python\Products\ots_laering\ots_laeringLogic.py, line 196, in _drawTriangle (Object: laering) File C:\zope23\lib\python\OFS\ObjectManager.py, line 272, in _setObject (Object: laering) File C:\zope23\lib\python\OFS\ObjectManager.py, line 147, in checkValidId (Object: laering) So it seems that the Image gets saved OK ... somewhere, but I cannot se the id via self.objectIds() which simply returns an empty tuple (). My object inherits ObjectManager, but it doesn't seem like the Image gets saved in it. I can see it in a dtml page like <dtml-var laeringsGraf> but apparantly it's saved somewhere else .... I'm completely baffled. I check for existance of the image like so:: def updateGraph(self): "Render graf if it doesn't exist" imageID = 'laeringsGraf' print 'objects:', self.objectIds() if imageID in self.objectIds(): # allready exists pass else: # doesnt exist, so render first time self._drawTriangle([150, 0, 0, 0], 10, 10) The following is the snippet of code that saves the image from PIL into the ObjectManager # save it in the ZODB outf = StringIO() im.save(outf, 'GIF') del im data = outf.getvalue() outf.close() imageID = 'laeringsGraf' self._setObject(imageID, OFS.Image.Image(imageID,'Lærings graf','')) self._getOb(imageID).update_data(data) Anybody's got a clue??? Please. Regard Max M

Insert file through ftp.
by After Dark 31 May '01

31 May '01

Can I insert a file throuht ftp and define its type or change it later? I made a product PrX ,with OFS.File and Catalog, and I want to put many files into my project and that its type to be of PrX. I think that the easiest way to do that is through ftp. There are 2005 files to insert with the meta_type of PrX, wouldn`t be possible to do one each time. How can I do that?? -- --Ricardo Kohler Costa ________________________________________________ Don't E-Mail, ZipMail! http://www.zipmail.com/

dtml-tree: controlling expanded nodes
by Markus Kemmerling 31 May '01

31 May '01

Is there any >>simple<< way to tell a DTML method with a tree tag to expand a node when it is called for the first time? This obviously meens to pass a tree-e parameter, but how to find out the correct value? I use the tree tag to show a list of folders and DTML documents in it and would like to pass the ids of folders to expand (one would be enough). Any hint appreciated, Markus Kemmerling

Python Scripts
by Tom Deprez 31 May '01

31 May '01

Hi, How can we in the python script check if the a certain variable exists in the namespace? ie. We can get the value of a variable by using context.myvar or context['myvar'], but both will return an error when the myvar doesn't exists. Now, how can you check if it exists? I tried several things, like context.hasattr('myvar') or context.has_key('myvar') , _hasattr(), _.hasattr() ... etc, but none seem to work. Can somebody tell me if it even is possible? Thanks. Tom.

MailForm

31 May '01

hi, I'm doing a simple mail form according to a HOWTO on the zope site. When I submit the mail form I get: Zope Error Zope has encountered an error while publishing this resource. Error Type: TypeError Error Value: len() of unsized object And am not sure why. It's pretty simple DTML and I understand it all. I'm using: Zope Version Zope 2.3.2 (source release, python 1.5.2, linux2) Python Version 1.5.2 (#0, Dec 27 2000, 13:59:38) [GCC 2.95.2 20000220 (Debian GNU/Linux)] System Platform linux2 Process Id 20502 (2051) Running For 19 days 2 hours 28 min 15 sec Thanks, j. ...................... .....

RE: RE:[Zope] how many zope member ?

Ok, i know it is difficult to define how many people are active with zope, but i only wanted some numbers to show how the Zope community are increasing since zope is an open source.

Of these 100 there are about 5 very active users and about 5-10 not so active. Of these 10 I am (probably) the only one subscribed to zope(a)zope.org.

Dispensing with querystring?
by Wade Leftwich 31 May '01

31 May '01

I've got an application that has Urls like this: www.myzopesite.com/article?id=42 Is it possible to rewrite the 'article' object so that a Url like this => www.myzopesite.com/article/42.html <= will work? That is, I don't want 'article' to try to acquire '42.html' anywhere; I want it to process id=42. Any advice appreciated. Wade Leftwich Ithaca, NY
