ZClient uses
by Tim Wilson 01 Sep '99

01 Sep '99

Hi everyone, I'm interested in knowing more about ZClient. Would someone be so kind as to suggest a few interesting things that ZClient is especially suited for? I'm trying to get the big picture and figure out where ZClient fits into the whole of Zope. Specific examples would be great. -Tim -- Timothy Wilson | "The faster you | Check out: Henry Sibley H.S. | go, the shorter | http://slashdot.org/ W.

RE: [Zope] How to replace NULL values in a database query

Jim, are you by any chance using Brian Hooper's Sybase DA? If so, please note that this DA handles null values poorly out of the box. I have a simple patch that fixes this and other somewhat severe problems with this DA. -- Alexander Staubo http://www.mop.no/~alex/ "Elvis skipped around the car and threw open the trunk. 'Hoopla!' he was heard to say, 'This is a 7.62mm M134 General Electric Minigun. Up to 6,000 rounds per minute. 7.62mm X 51 shells. 1.36kg recoil adaptors. Six muzzle velocity of 869m/s.'

Setting object properties
by Victor Ng 01 Sep '99

01 Sep '99

I think this is a general problem I'm having with Zope - but anyway... I'm using the ZClasses Tutorial with the CDClass and I'm having problems trying to set the properties of the object. The result set gives me the 'old' artist value that I used when I first added the myCD object. CD Info: <dtml-call "myCD.manage_changeProperties({'artist':'Victor Ng'})"> <dtml-with myCD> Title: <dtml-var title> Artist: <dtml-var artist> Description: <dtml-var description html_quote newline_to_br> </dtml-with> More generally, is there a facility in Zope so that I can create variables in the DTML document that are _not_ properties of the DTML document? I just want to create a temporary local variable that I can assign things to, and then toss out. Am I not understanding something here? It seems like DTML scripts are very limited in functionality - they just seem to 'read' the output of ZSQL methods or Python methods. Vic

Some questions about "in"!
by Elaine Kong 01 Sep '99

01 Sep '99

Hi,everybody, If i have the tree like: +index_html(DTML Document) -lib(folder) -lib1(subfolder) +introducation(DTML Document) +history(DTML Document) . . -lib2(subfolder) +introduaction(DTML Document) +history(DTML Document) . . Now the index_html has two line  and . If the lib1 call index_html, it will return the introducation and history of lib1,etc.But if i want to add something ,it must change the index_html. I don't want to change the index_html. I want to use "in" tag in the index_html and change the name of introducation and history to 0001 , 0002. If i want to add something in the index_html. I can just correct the name(0001,...) and add a new DTML Document in the subfolder of lib. How can i do that? Hope that you can help me to solve this question! Thanks, Elaine Kong.
