[Fwd: [Zope] A few quickie (newbieish) questions]
by Joe Grace 12 Aug '99

12 Aug '99

Dear Zope'sters, I would dearly appreciate a little help if possible. Thanks, = Joe = P.s., I'm using Zope 2b3 (not b1). -------- Original Message -------- Subject: [Zope] A few quickie (newbieish) questions Date: Wed, 11 Aug 1999 07:58:53 -0700 From: Joe Grace <occam(a)serv.net> To: zope(a)zope.org CC: me <occam(a)wizards.com> Hi, I'm hoping I can get some quickie questions answered which have been nettling me (I'm using Zope 2b1). I'm getting some good stuff working, but it seems to be a few nagging, simple things which are tricky. Rather than just finding a (probably overly complex) way, I'm hoping someone(s :-) can set me back onto the Zope Zen path for idiomatic simplicity. (Other Zope idiomatic tips would be welcome as well.) Hmm, perhaps a Zope idiom document would be nice!-) 1. Custom dates with correct timezone?. I store a date using fmt="aCommon" in a folder property. Works great when I display it using fmt="aCommon" meaning that the time agrees with the time in my current time zone (PST). It also lists properly from the FolderName/Properties Zope management page. However, when I try to display it as fmt="%b/%d" or fmt="%x %X", the time (or day) is off by 7 hours ahead. Is there an easy way to get custom dates with automatic timezone accuracy (i.e., what am I missing?)? 2. Avoid duplicate pathing? How do I refer to the current folder properly (e.g., for a reload)? Perhaps I just need to reload? I tried FolderName by acquisition which "worked" except that it keeps appending a new FolderName to my address each time its used, e.g., ".../FolderName/" becomes ".../FolderName/FolderName/". What is the Zopish way to get the same behavior but without the duplicated FolderNames? 3. Correct (simplest, most robust?) server-side interconnect for Zope and Java (e.g., JPython)? Hmm, maybe this isn't a quickie, but help/pointers/options would be welcome nevertheless. Is there a standard way to get my java talking with Zope? Perhaps *CGI is the correct tool for this task (I'm new to web stuff)? Basically, I want to get my Zope and Java talking closely. Performance is not a key issue (but nice of course for scalability later on). Right now, I'd just like to get stuff working in some proper (hopefully standard) way with the option to optimize later on. One suggestion I've heard is XML-RPC which certainly is interesting but seems a little heavyweight perhaps since I'm willing to have python talk directly with JPython. (Wishful thinking alert!-) Is there some tricky way to get Java and Zope running in-process together? Short of that, are there some standard options for this sort of thing? Thanks in advance! BTW, I'm enjoying my Zoping. I added several features to my site on request yesterday which was nice turnaround for a newbie. Zope can be very satisfying to use! (Thanks DC!)

Calling external methods with the current object
by Martijn Faassen 12 Aug '99

12 Aug '99

Hi there, I keep running into variations of this problem. I want to call an external method and pass the 'self' object (and REQUEST) to it, but explicitly. But still the *current* self. So I have an external method like this: def foo(self, REQUEST): pass The Advanced DTML Howto mentions this: ---- Variable rendering The DTML var tag does not merely lookup variables, but it "renders" them. The process of rendering is not just coercing objects into strings, but calling objects if they are callable, and handling DTML objects specially. Zope's rendering rules are designed to do what Zope thinks is the right way to display an object. However, you may not always want to let Zope render and object automatically. For example, Zope normally renders DTML objects referred to in other DTML objects by calling them the with current DTML namespace stack. ---- And then it goes on how to call it with *other* DTML namespace stacks. But how do I refer to the current DTML namespace stack explicitly? 'self' in DTML doesn't work. Regards, Martijn

There aren't just simple INSERT's or UPDATE's There are tables that should be opened, complex operations that should be made so I need an external program written for example in Tcl that will operate with lists, arrays and so on. I realise that a Python module would be just fine but I'm not familiar with Python. There should be some simple "exec myprogram" tricks that would allow execution of any external program. -- Constantin Teodorescu FLEX Consulting Braila, ROMANIA

Public CVS checkout hasn't updated files in several days

I've been maintaining my copy of Zope using public CVS. When I ran this command: cvs -z7 -q up -P -d on August 10 and again on August 12 (today), there were no changes. I think the last time I received updates was August 5. Surely there have been changes since then. Cheers, Jim
