A few quickie (newbieish) questions
by Joe Grace 11 Aug '99

11 Aug '99

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!) Cheers, = Joe =

Database choice

Hi all, This is an off-topic question, but I wonder if somebody can help me decide. What database should you use? SyBase or PostGresSql? Both are free... Regards, Tom.

What is a phone number? :-) There are the following formats in use: +1 555 555 1212 (ISO standard) (555) 555-1212 555.555.1212 555-555-1212 And I'm sure dozens more :-) The problem with "validation" is that it's *very* application dependent. You might also want to validate that the area code matches the state, etc. Chris -- | Christopher Petrilli Python Powered Digital Creations, Inc. | petrilli(a)digicool.com http://www.digicool.com

Database connection objects automatically connect when they are "woken up" from the object database (unless for some reason they cannot connect, like a bad connection string or something...). You don't need to worry about connecting them manually. Brian Lloyd brian(a)digicool.com Software Engineer 540.371.6909 Digital Creations http://www.digicool.com

There are many ways of approaching this. One is: F1: Form that collects info (some Javascript data validation) D1: Target of F1 with some DTML that also does data validation ZSQL1: SQL Method --Rob

ZSQL Question - required type
by Harry Page 11 Aug '99

11 Aug '99

I have created a ZSQLMethod which does an insert into a table. All arguments have the "required" type. When I test the method this works fine. The problem comes when I call the method through a DTML document as the required type seems to be ignored. Is this correct behavior? Is it normal to POST form data to an intermediate DTML document or direct to the query template? I need to do some data validation along the way.
