Dynamic ordering of DTML-IN?
by Andy Gates 23 Jan '01

23 Jan '01

Another one from the "my brain don't work" side of the tracks: I have a staff list that I want to be orderable by first or last name. So I have buttons for each that link thus: <a href="staff?orderby=firstname"> etc The idea is that that feeds over to the DTML-IN tag thus: <dtml-in "sql_search(search='foo')" sort=orderby> But this barfs, because it's expecting a field name "orderby" and there isn't one. How do I evaluate that? ---------------------- Andy Gates, Learning and Research Technology Andy.Gates(a)bristol.ac.uk - ICQ#74362415 http://www.ilrt.bristol.ac.uk

I don't think I get what you mean by "extender shell". As far as I know (never used it though), PostgreSQL works on win32. I'd ask on the postgres lists first, though. -- Petru Paler, mailto:ppetru@ppetru.net http://www.ppetru.net - ICQ: 41817235 _______________________________________________ Zope maillist - Zope(a)zope.org http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

Getting an object from it's id
by Gale 23 Jan '01

23 Jan '01

Hi, This is obviously a newbie question. I have several places in my dtml code where in order to obtain an object I loop through objects of that kind and make a test to determine if each objects id matches the id I picked up from a form. This is the only way I could get it to work; but I feel there must be a better, more efficient way. Here is an example: <dtml-in expr="objectValues('Folder')"> <dtml-if "myId==id"> Once I get a match I then proceed to use it in subsequent code, such as a <dtml with id> and it works since id now refers to the object I'm interested in. Is there a Zope API method that will allow me to get an object from it's id, or can I write a simple Python method to do it, or am I missing something even more obvious? Thanks Geoff Armstrong

Re: [Zope] Zope, database field formats, output format of queries

What do you mean with a Zope based database? If you mean an external database, look for the datatypes and restrictions, they support for column values. SQL 3 may give you some of what you want. Whether internal or external, you can control what goes through Zope to your database. You will probably need External Methods to get the full Python power, see "python.org" for documentation about Pythons vast library. You will be especially interested in the "re" module. It implements (Perl style) regular expressions. Dieter
