Just thought we'd mention that we have gotten lots of great comments on the Zope book so far, especially in the last week or so. You're all helping make it a better book and ensuring Zope's future. if you've felt in the past that you may not be technically proficient enough to contribute to the technology of Zope, you can certainly contribute to the documentation by catching our mistakes and making good observations and asking good questions. It is really, really helping. Keep it up, cuz we're not done yet! Thanks, Michel and Amos

dtml-sqltest and capital column names
by Oliver Bleutgen 12 Oct '00

12 Oct '00

Hi, I'm using zope 2.2.2 with postgres 7.0.2 and ZPopyDA 0.6.4. I encountered a problem with dtml-sqltest and capitals in column names. Well, I simply couldn't get it to work because postgres requires column-names with "special characters" like capitals to be enclosed with quotation marks, ie. "COLUMNNAME" instead of COLUMNNAME - IIRC '_' also won't work. The problem is that dtml-sqltest only renders select * from table where COLUMNNAME='5' which will be interpreted by postgres like select * from table where columnname='5' Unfortunatly <dtml-sqltest bla column="BLA" type=int> throws the obvious error and everything else I tried didn't work too. In the end I patched lib/python/Shared/DC/ZRDB/sqltest.py to do what I want. 165,166c165,166 < if has_key('column'): self.column=args['column'] < else: self.column=self.__name__ --- > if has_key('column'): self.column='"'+args['column']+'"' > else: self.column='"'+self.__name__+'"' Any comment whether this would also apply/be necessary for other dbs? And if not, would there a better place (anywhere in ZPopyDA) to change/add some code? Or did I just miss something obvious and there's a sane way to make dtml-sqltest work with postgres and capitals. cheers, oliver

Need preferred 'import' format for ReportLab Image module
by Tony McDonald 12 Oct '00

12 Oct '00

Hi all, This is of interest to those people using the (excellent) PDF generator, ReportLab <http://www.reportlab.com/> under Zope. As you may know, there is an import conflict with the 'Image' module from PIL and the built in Zope 'Image' module when using ReportLab. The snippet below is from the main ReportLab developer, Andy Robinson. > If it's not too much trouble, that would be very useful for > those of > us using Zope (the number is growing all the time). > We will try to do this. But which import format does Zope require? 'import Image' of 'import PIL.Image'? And is this some sort of packaged 'PIL-for-Zope'? If it was just PIL on your hard disk, you would have 100% control over the problem just by adding the right directory to your path. Sorry, I'm working all hours and don't have time to download and play with Zope this month. - Andy ------ So, can anyone with a higher 'import' Zope Zen please give me a clue as to how to reply to Andy? In my own reportlab distribution I changed; import Image to from PIL import Image and that seemed ok, but I'd like a 'definitive' answer on this from some bods with Nirvana-level Zen.... BTW, If you're not a reportlab user (open source, free download), then you're missing out - this is terrific software...we have it connected to ZSQL methods and are churning out PDF documents *very* quickly. cheers, Tone

Catalog and Proximity searches
by Jason Spisak 12 Oct '00

Zopsters, Does anyone know if the Catalog is supposed to do proximity searches, ie: "visual basic" would return the phrase. Thanks, Jason Spisak 444(a)hiretechs.com

Problem with 2.2.2 and date properties?
by Timothy Wilson 12 Oct '00

12 Oct '00

Hi everyone, I'm having trouble with a ZClass I've created that uses, among others, two date properties. I'm suddenly having problems creating new instances or working with existing instances of my ZClass. I can't be sure, but it seems like the onset of the problems coincided with my upgrade to 2.2.2. Has anyone else seen any problems with date properties and Zope 2.2.2? -Tim -- Tim Wilson | Visit Sibley online: | Check out: Henry Sibley HS | http://www.isd197.k12.mn.us/ | http://www.zope.org/ W.

Thanks : bobo : where to find it ?
by Emmanuel DISCORS 12 Oct '00

12 Oct '00

Thanks to you Paul & Jim Have found some 'Bobo' packages in tar.gz Zope archive. (V:2.2.2) - DocumentTemplate - ZPublisher BUT NO BoboPos directory in the lib/python ; only ZODB. Is there a mistake in the README.txt or forget in the lib/python directory ? Need a DB system to try the Trinkets.py (Having ZODB from Zope 2.2.2 and BoboPOS3-alpha1 & BoboPOS-2.0.2 from old backup...) What is the best way ? Old BoboPos or start now with ZODB ? Thanks Emmanuel -- ================ Emmanuel DISCORS Tel & Fax : 02 54 56 80 61 ================ Conception, Informatique, Réseau ADVL ( Au-Delà de Vos Limites ) Site web : http://www.advl.org/ Archives mOdbc : http://www.advl.org/public/mOdbc/ Jim : ==== We o longer distribute Bobo, although I'm sure you can find it on some archive somewhere. Of course, the pieces that made up Bobo are still available, in updated form, as part of the Zope distribution. The medusa bobo is available in the medusa CVS in the contrib directory. If there is still a medusa distribution, I imagine it contains this directory too. Jim Paul : ===== Hello Emmanuel. Bobo has been folded into Zope: http://www.zope.org/ --Paul

[Fwd: Re: [Zope] dtml-in loop to capture records]
by Paul Zwarts 12 Oct '00

12 Oct '00

Me again, To further explain my dilemna, I just noticed that using the in ITEM loop doesnt seem to work if the dtml-call statement has an extra parameter. I had <dtml-call "verifyLog(mdate=mdate)"> publish.. <dtml-in item> ... ... </dtml-in> Then use as in other working forms: <dtml-call verifyLog> publish.. <dtml-in item> ... ... </dtml-in> Mdate is the primary key, again. This gave me the ITEM Bad Request error. Now, if I remove the mdate call, and remove the condition in the ZSQL method, i can at least now get an error: File /var/Zope-201/lib/python/DocumentTemplate/DT_String.py, line 502, in __call__ (Object: <string>) File /var/Zope-201/lib/python/DocumentTemplate/DT_In.py, line 691, in renderwob (Object: item) File /var/Zope-201/lib/python/Shared/DC/ZRDB/sqlvar.py, line 168, in render (Object: vswitch) Missing Input: (see above) So, the item is rendering. The variable named item.vswitch is not... nor is mdate which had to be named as an item.mdate instead of being passed in the dtml-call statement as an argument. In forms where this works, i simply call the method and the item renders everything in properly. Now I can do none it seems. One other note is that I var in the form that the input item.fieldname parts are contained, so the calling method to render item is not the same document as the item components.

Competing writes and reindexing objects
by Jason Spisak 12 Oct '00

12 Oct '00

Zopists, I am trying to eliminate the competing writes that are plaguing my app at the moment. One way I know of is to make sure that people aren't creating/modifying objects in the same folder at the same time. This is becuase the parent object gets modified too. Does anyone have a "object creation/folder distribution" code that works for them that they would be willing to share? Lastly, even if I distribute my objects, doesn't reindexing any Zope object inthe Catalog at the same time create a conlict? I'd love to know if I'm fighting a losing battle here. All my best, Jason Spisak 444(a)hiretechs.com
