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

Tutorial Question
by Mike Malloy 08 May '01

08 May '01

Please pardon if this has been answered before. I did make an attempt at looking through the mail archives. When trying to add the Zope Tutorial, I get the following error after giving it an id and clicking Add Invalid connection string: demo There is a long stack trace that can be sent if needed to help debug this. If this is a known issue, please let me know what the workaround is. Best Regards, Mike Malloy __________________________________________________ Do You Yahoo!? Yahoo!

Re: [Zope] Where may I find some discussions about the pros and cons of Zope vs ASP vs PHP, etc...
by Tommy Johnson 08 May '01

08 May '01

><experiencedwiththemallme> >From static HTML -> ASP = Wow! >From ASP -> PHP/Coldfusion = Chock! >From PHP/Coldfusion -> Zope = Heart attack! ></experiencedwiththemallme> This is exactly the way I progressed: HTML to ASP ASP to ColdFusion Coldfusion to Zope And I am experiencing a heart attack, along with a stroke. And just this morning, I found a patch of grey hairs. I hope it gets better, I've only been in this Zope experience for 2 1/2 weeks now.

But then the result *IS* correct, too! If you have, as is you example: enddate=<todays date without time> then DateTime().lessThanOrEqual(enddate) must return "false" most of the day. As the name suggests: "DateTime" is date *AND* time. "lessThanOrEqual" must take both components into account. Dieter
