Dear Zopers, Just to let you know that ZOPE is better than DOPE! Thanks for the great work Paul and gang. Below is a press release made today for our site that uses Zope and Squishdot as the main (but not only part) of the site. Press Release 70South, the website that has been providing news and views on Antarctica for nearly a year, today announced the introduction of WAP information services. The Wireless Application Protocol (WAP) is fast becoming the standard for mobile and wireless data applications. In the next 12 months almost every operator as well as most companies will be offering WAP services, ranging from commerce, banking and payment to gaming, entertainment and information services. Now you can get your Antarctic news and views on the move, where ever and when ever you like. About 70South Formed in mid 1999 70South has been providing visitors with daily news and views on or related to Antarctica. An important aspect of the site is that visitors can not only read, and comment on existing articles, but post their own related articles. -------------------------------------------------------------------------------------------------------------------- For the latest news and views on Antarctica visit http://www.70south.com

help with zodb
by Garrett G. Hodgson 02 Mar '00

02 Mar '00

thank you for your help. forgive my being obtuse, but i'm still not getting it. Jeff K. Hoffman jeff.hoffman(a)goingv.com wrote: > Only one process can access a ZODB at a time. You have two.

By the > time you've gotten there, Zope already has it open. ok, then how does code in my external method get at that? that is, how do i create an object and stuff it in the DB? all the code examples i've seen follow the pattern in GetPeople(). > AFAIK, you simply need to create an instance of your object and set it as > an attribute of another persistent object. The persistence should happen > automatically. how do i do this? i get the feeling i'm just missing something, perhaps thinking like a python programmer rather than a zope guru. i feel like there's some big obvious point that has escaped me, and i'm waiting for the big "AHA!". so, one more try. given the following external method: import ZODB, ZODB.FileStorage def GetPeople( self ): "Return list of people in DB" db = ZODB.DB( ZODB.FileStorage.FileStorage( 'TestDB.fs' ) ) connection = db.open() root = connection.root() people = [] for key in root.keys(): people.append( root[ key ] ) return people if __name__ == '__main__': for person in GetPeople( None ): print person.name, 'is', person.age, 'years old' referenced from a DTML Method: <dtml-in "GetPeople()"> <dtml-var name> is <dtml-var age> years old.<br> </dtml-in> when i restart zope and view the method, it works once, but shows no persons. the second time, it fails with the traceback. what do i change to make it work? thank you for your patience. -- Garry Hodgson Every night garry(a)sage.att.com a child is born Software Innovation Services is a Holy Night.

y2kbug - bobobase_modification_time one day back
by Wolfgang Strobl 02 Mar '00

02 Mar '00

This ist a typical Y2K bug, located in the module TimpeStamp.c, as I suspected earlier. Since nobody followed my hint from earlier this day so far, I took the opportunity to dig a little deeper, learning how to build and replace a python extension on the way. Given how little documentation there is, I don't claim having understood anything about, but noticing that the function static double TimeStamp_abst(int y, int mo, int d, int m, int s) gets called with y=100 (not 2000), changing the leap yar calculation l = y%4==0 && (y%100 != 0 || y%400==0); to l = y%4==0 && (y%100 != 0 || (y+1900)%400==0); in that function fixed the problem on my system. DTML Document at /y2k / t <dtml-var standard_html_header> <h2><dtml-var title_or_id></h2> <p> This is the <dtml-var id> Document. </p> <dtml-var "bobobase_modification_time()"><br> <dtml-var "_.DateTime()"> <dtml-var standard_html_footer> renders as This is the t Document. 2000/03/02 23:13:8.393 GMT+1 2000/03/02 23:13:54.619 GMT+1 now. The complete function from ZODB/TimeStamp.c in context: -------------------------------------------------------- static double TimeStamp_abst(int y, int mo, int d, int m, int s) { int l; l = y%4==0 && (y%100 != 0 || (y+1900)%400==0); // y2kfix ws 2000-03-02 // was l = y%4==0 && (y%100 != 0 || y%400==0); return (TimeStamp_yad(y)+ joff[l][mo]+d)*86400 + m*60 + s; } -------------------------------------------------------- Hope this hilft. :-} ------- End of forwarded message ------- -- Wolfgang Strobl

Security Puzzler
by James W. Howe 02 Mar '00

02 Mar '00

I was working with my ZClasses today and was confronted with something which seems strange. I was editing a method defined in my ZClass when I tried to click on the "propertysheets" link displayed at the top of the edit screen: DTMLMethod at / ControlPanel / Products / <product> / <zclass> / propertysheets / methods / <method name> When I clicked on the link, a basic authorization dialog was displayed. I was already logged in as the superuser. Why am I getting an authorization dialog? Mostly just curious. Thanks. James W.

FieldIndex atomicity?
by Lalo Martins 02 Mar '00

02 Mar '00

If a FieldIndex is treated as atomic, it shouldn't go trough the Splitter, right? I found out that an hyphen in a field indexed as FieldIndex breaks the index (this field is just not indexed, it seems). A space works. Weird. []s, |alo +---- -- I am Lalo of deB-org.

SQLSession and Performance issues
by Timothy Grant 02 Mar '00

02 Mar '00

Hi all, I have a form on which I am having some interesting performance issues, I think, but am not sure that it is my extensive use of SQLSession variables throughout the form. I have a single page data entry form where almost every field gets stored in the SESSION. This form can take from 9 to 15 seconds to display. When all my other forms take 1 to 3 seconds this is a significant slowdown. I am curious as to what methods may be used to reduce calls to SESSION['varname'], or if I am even barking up the right tree. Thanks. -- Stand Fast, tjg.

directory importation
by Jessica Tishmack 02 Mar '00

02 Mar '00

Hello, I am a first time user of Zope, and have been looking through a lot of documentation, but can't seem to find an answer to what seems should be an obvious one...so any help would be appreciated. I already have an existing website on a Linux platform, with many many folders/files...to have to manually add each of these files to Zope seems very inefficient. How do I import an entire directory into Zope? Thanks, Jessica

How does Zope.org site implement "Printable Page" option I see the pp=1 and presume this is some kind of var. I have reason to want to do this, and I kindof get the idea, but I would like to know how the pro's do it!! Thanks -- Robert Geiger robert(a)geigers.net

Extracting Text from both parent/child XMLDocument Objects
by Techlists 02 Mar '00

I am trying to use XMLDocument to print text in html that has the following XML structure: <copyright>Copyright <copyrite.year>2000</copyrite.year>, by <copyrite.holder>MyCompany.com</copyrite.holder>, All rights reserved.</copyright> I want it to print in html: <p>Copyright, 2000, <i>MyCompany.com</i>, All rights reserved. Any thoughts on the dtml needed to do this kind of DOM traversal that included the text (in linear order) of both parent and child tags? Thanks, Sean -- --Sean D.
