I'm completely new to Zope and am starting out with something I imagine is amazingly simple - but after many attempts and perusals of docs and lists, I'm still unable to figure this one out...
Using ZPT - how do I get the value returned from a ZSql method? This method only ever returns *one* value; I'd rather not do a tal:repeat if I'm able to.
Whats wrong with repeat here? repeat would give you if <yourmethod> and variabe defining the same time. You can do it without repeat, but it will be worser. <span tal:repeat="foo here/your_ZSql_method" tal:content="foo/column">wopp</span>
The best I can do is:
<span tal:replace="here/my_ZSql_method">
Which provides:
"<Shared.DC.ZRDB.Results.Results instance at 0x8c6df8c>"
ZSQL method always return an object which behaves like a list of zero or more objects which behave like an dictionary and an object with attributes the same time (so you can write result[index].column or result[index]['column']
I don't want the instance - I want the value, of course.
( My lack of Python knowhow may make the obvious less so )
You should really really not hesiate to learn python any more :) Just give the tutorial on python.org a try, it will clarify much of your questions out. Keep in mind: python does not bite. :)
Also - could someone point me to the document(s) that explain or show an example of this? I was unable to find it explained anywhere.
There's a ton of stuff on DTML - but I'm only interested in using ZPT wherever possible. Shouldn't the Zope Book ( I'm reading v. 2.6 ) try to use ZPT in all it's standard examples rather than DTML?
I would like to see that too. But unfortunately...
Why can't ZPT be used in other places, like ZSql methods? There is some
Guess why ;) Try to build up an example ;)
serious confusion on where to use ZPT and where to use DTML. Why should a new user be required to learn *both* -- especialy when it's arguable that ZPT is more "correct" ( in so far as much as better separation of logic from presentation, html/xml friendly, etc., etc. )
I get the distinct impression from the zope-dev list that ZPT is, generaly, the new desired replacement for DTML for most uses.
Um. The replacement consists of Python Scripts + ZPT, not ZPT allone.
