CMFOptions 1.0 with Blark Weblog
by Jeff Sasmor 08 May '01

08 May '01

CMFOptions 1.0 has been released. It includes minor updates to the CMFExtFile and CMFExtImage content types, as well as a new content type called Blark. Blark is a weblog, similar in concept to Squishdot (and it looks a bit like it) but tailored for the CMF. It's not a CMF 'skin', but rather a CMF content object that is instantiated in a Member directory (it can even be the index_html for the member). Blark has been beta tested at http://www.yellowbrain.com/ (where you can try it out as long as that web site remains active) but probably still has a few nits in it. You can read more at: http://www.zope.org/Members/jeffsasmor/CMFOptions/ Enjoy! (sorry for crossposting, but the last time I posted only to zope-announce folks complained. Go figure. ) Jeff Sasmor jeff(a)sasmor.com Check out http://www.naggle.com/

RE: [Zope] zeo database

I don't think this is the case by default; the 2gb limit is a pre-existing limitation in ext2, which is the default filesystem in Linux 2.4. Not until Linux 2.4.1 did an alternate filesystem add features to remove this barrier (ReiserFS), and it is not the default. In addition to ReiserFS, SGI's XFS and IBM's AFS seem to address large file support and are all avilable as patches to the mainstream kernel. However, doesn't Python impose some sort of limit as well? Anyone have a number? Does this depend on the architecture of the machine (i.e. 64 vs. 32 bit)?

Changing of the SQL guard
by Paul Zwarts 08 May '01

08 May '01

Greets all, I have installed a newer version of postgres on my linux box, along with the newer PoPy adapter and I have done some work in splitting out tables to separate dbs... The problem I'm faced with is that I have to reidentify all of the connections that each ZSQL method addresses to the adapter. Instead of manually changing each one (which are too many to count), is there a way I can do them all at once? The second db I use is very isolated so if I could just tell an entire tree to goto on db connection, that would be nice... I even tried using the same object name, but Im sure there is more hidden stuff behind its ID that this doesnt work... Can anyone help me please? TIA, Paz

Re: [Zope] getPropertyType

Tim Hicks writes: > ... problem with "PropertySheet.getPropertyType" ... This might be a bug. I looked in the code at "OFS.PropertySheets". "getPropertyType" is very differently implemented than "hasProperty". "getPropertyType" looks at "self.p_self()._properties" while "hasProperty" looks at "self._propertyMap". This is very suspicious. At your place, I would make "getPropertyType" similar to "hasProperty" and if that gives you the correct result, file a bug report into the collector. Dieter

Setting SELECTED in select box
by Gitte Wange 08 May '01

08 May '01

Hello, I have run into this weird problem: I am trying to set an option in a select box SELECTED in the id of the option is the same as the value of the select box. The code looks like this: <SELECT NAME="fileid" SIZE="1"> <OPTION VALUE="0">-- Select mediafile --</OPTION> <dtml-in sqlGetMediafiles> <dtml-if fileid> <dtml-if expr="fileid == id"> <OPTION VALUE="<dtml-var id>" SELECTED><dtml-var filename></OPTION> <dtml-else> <OPTION VALUE="<dtml-var id>"><dtml-var filename></OPTION> </dtml-if> <dtml-else> <OPTION VALUE="<dtml-var id>"><dtml-var filename></OPTION> </dtml-if> </dtml-in> </SELECT> Now when I have selected a file, I can see that the fileid variable is set. Well then the select box should select the file that has that id right? But it doesn't - it doesn't select anything. Can anyone help me?

index_html a script, not a template
by Peter Bengtsson 08 May '01

08 May '01

[1st: Sorry for crossposting, but now it actually makes sense] Under the topic: "Relying on scripts" in Jim Fultons IPC9 presentation on Presentation Templates http://www.zope.org/Members/jim/Info/IPC9/PresentationTemplates/index.htm "Maybe scripts, rather than templates will commonly be URL target." -- from http://www.zope.org/Members/jim/Info/IPC9/PresentationTemplates/text20.htm Until the last couple of days I'have always made DTML Methods or DTML Documents for everything that users type into the addressbar like "index_html" or "about". I.e. I start with a template and most likely end up in a template. It shouldn't be like that, should it, always. Because some of my templates might look like this: <dtml-var standard_html_header> <dtml-if "iscooluser_externalpy_orscript()"> <dtml-with foo><dtml-var showthat></dtml-with> <dtml-else> <dtml-with bar><dtml-var showthis></dtml-with> </dtml-if> <dtml-var standard_html_footer> Recently my sites are filled with sometimes three times as many python scripts as DTML objects. And Jerome Alets Zshell really opened my eyes for loosing templates. Am I alone on using templating objects for URL-hitting objects? What are the implications (performance, scalability in terms of feature changes, etc.) of using Python Scripts or External Method instead of templates? Is there a paradigm shift with these promising Page Templates (see quote above)? Advice from people with zen?!?! Trying to see as long as possible, Peter

Fw: [Zope] DateTime() BUG!
by Andreas Jung 08 May '01

08 May '01

----- Original Message ----- From: "Kai Hofmann" <hofmann(a)isl.org>> > From my point this is not correct, because of the following points: > > 1) within the enddate there is no time defined - so it is NOT possible to > compare the time - following your argument - the result should be a TYPE > ERROR, because its not possible to compare a date/time pair with a date <DISAGREE> When you enter a new date property to an object then this date is converted to an instance of DateTime (see PropertyManager and Converts module). The DateTime constructor assumes 00:00 when now time is given in the date string. This is a common used semantics. </DISAGREE> > 2) A date only describes a whole day - so comparing it with a date/time pair > should always result in a compare of the dates only - because the time is > out of interest here (its always within the date range). see above... When you only want to handle with dates you should avoid using the DateTime() constructor for comparision issues because it uses the current time. Andreas

is ZEO the answer?
by Erik Myllymaki 08 May '01

08 May '01

I would like to publish my Zope site internally (Intranet) via HTTP AND externally via HTTPS (Internet). Should I be looking at ZEO or another option? Using on HTTPS server for both would be the easiest, but the intranet use is pretty heavy and I don't want to incure the overhead of SSL on what doesn't need to be encrypted. Thanks in advance, Erik Myllymaki erik(a)pacific-shores.com
