zope higher abstraction installation
by Olaf Zanger 31 May '01

31 May '01

hi there, on the survey on digicool i added some ideas to make the first step into zope easier. i'd like to hear your ideas about that and if any of that is already acomplished somewhere. * a roundtrip visual-RAD-database form/reports environment (visual to source and back) (better than MS-Access and probably with import of forms/reports form theKompany-REKALL and MS Access or other forms/reports designers :-) * out of the box multi language and database support * a closed zope installation option. means zope does not use local python or so. i had heaps of trouble with different versions of python, python-database modules and db-connector products (i rather have two pythons on disc than troubles with zope after updating my suse distro) still not solved after 3 months :-(. actually this stopped development of a product on zope. * faster implementation of patches (there is one problem with dtml-in orphans trouble that got a patch about 6 months ago and is still not solved in new zope versions) * a setup process, where the newbee-user can select what products should be pre installed. (e.g. according to usage questions like news-discussion -> squishdot, db-mysql -> MySQLdb+formulator db-pgsql -> PgSQLdb+ZDatabaseTool+QueryWizard(hopefully to be released by easyleading), Content-management -> CMF, XML, Templates -> ZPT, PIM -> iuveno-projector+others, eks -> KDESoHoServer-Components, multi-language-mysql -> MySQLdb+ZBabel, documentation -> local-zope-book, faq -> local-faq) -- this would show the capabilities of zope right away to the newbee. i remember how it took me weeks to figure out what zope can do. -- this also would move some zope companies into focus to the newbee that might want to spend money and outsource development. -- zope would grow into a plug-and-play-intranet/internet problem solver application hope for opinions olaf -- soli-con Engineering Zanger Dipl.-Ing.

CSS and Zope was: Thanks for the fish
by Paul Zwarts 31 May '01

31 May '01

Rich, Thanks a million for the positive comments. The site uses CSS in fact. It has problems on various browsers but I now have it working very stably and I'm happy with that. Perhaps I can capitalize on your comment and ask what people do for interbrowser CSSing. At the moment I am building a pre-render logic method that sets a browserlevel ID that changes the CSS depending on the browser type, but the incompatibilites are vast and not easily segregated. How does one make a few CSSs for all browsers? Or is the answer to NOT use CSS? anyone?

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.

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. ...................... .....

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
