Or for something with a gentler learning curve: http://www.zope.org/Documentation/Guides/ZSQL Go there and read the section on "Creating Search Interfaces." Zope will magically create a search query form and a table-formatted batching output method on the back end, based on an SQL Query method of your own design. So read that, do that, and then look at the methods it creates. I found it very useful in getting up to speed on how to roll my own batching DTML methods. -cw- PS - (OT rant warning) I have set everywhere I know of to tell %^#$@!

Re: [Zope] AArgh. Zope-2_2-branch and head of CVS breaks SQLMethods.

Aha! Nailed it. It's the 1.131 version of OFS/Application.py cvs log entry: ---------------------------- revision 1.131 date: 2000/08/02 17:31:54; author: brian; state: Exp; lines: +71 -46 branches: 1.131.4; Merged fix for products with old-style initialization not being properly filtered by permission in the filtered add list. ---------------------------- Ok, the problem is that when it sees an initialize() method, it stops looking for other stuff. ZSQLMethods has a __methods__ thing, tho. Oops. Patch appended to make it always look for __methods__. Note that it doesn't break ZSQLMethods from working, just from being added or edited. Argh. This would've been much easier to figure out if I hadn't managed to confuse myself (tooo many installations of zope, all slightly different - need to make it better :) Anthony >>> Anthony Baxter wrote > > The current Zope-2_2-branch and head of CVS is busted - you cannot add or > edit SQLMethods.

AArgh. Zope-2_2-branch and head of CVS breaks SQLMethods.
by Anthony Baxter 10 Aug '00

10 Aug '00

The current Zope-2_2-branch and head of CVS is busted - you cannot add or edit SQLMethods. It appears that Products.ZSQLMethods.__init__.__methods__ doesn't get into the namespace of the product properly, as neither the add or edit screens can see SQLConnectionIDs. Blah. More to come - I'll try to figure out why it's broken, and when. Anthony

file uploading from IE browser
by David Zhu 10 Aug '00

10 Aug '00

Hi All, I'ved followed the online How-To on implementing a simple service for parsing uploaded files via the browser. But strangely, it only works for Netscape browsers. When I test the uploading using IE, the supposed file object becomes a string object, causing all sorts of problems. How am I suppose to get the file object from IE browsers? Thanks in advance! Dave

newbie question -- can't delete toplevel folder
by Guy Middleton 10 Aug '00

10 Aug '00

I just installed Zope, and tried playing with it a bit. I can create a toplevel folder (in the "Zope" directory), but it then seems to be undeletable. Is this a problem, or is there something special about toplevel folders that I don't know? I can delete any contents I put in the folder with no problem, but not the folder itself.

Re: [Zope] dtml-in sort question

How does one sort the results returned by an > expression such as the above? I think so. Does it not? I probably would use "objectValues" instead of "objectItems". "objectIdems" gives you a sequence of "id,value" pairs, "objectValues" gives you just the sequence of values. If your objects should not have an "id", the sort above would not work. In this case, you could try: <dtml-in "PARENTS[0].objectItems(['ccDocClassMetaType'])" sort=sequence-key> Dieter
