oracle8 and cursors
by Andy Pahne 05 Jul '00

05 Jul '00

hi, there, i've been using oracle8 with zope succesfully for a while. now my database programmer came up with a solution for a certain problem, which "we cannot solve with an easy select statement". he told me, that we are gonna have to use db-cursors instead. i must admit that i have heard the therm cursor before, but i am not sure how to use them with zsql-methods. my question is fairly simple: is there any difference in handling cursors with zsql-methods in comparison to handling 'simple' select-statements? can i use <dtml-in "..."</dtml-in> to iterate over the result sets? I read DCOracle.txt which comes along with DCOracle-Product, but I do not understand it very well. Any recommended readings?

Comparing two dates WITH time?
by Nils Jeppe 05 Jul '00

05 Jul '00

Hello All, I need help again..... How do I compare two dates that include full timestamps? If I try date_updated <= ZopeTime() it works only for dates that do not include times... as soon as you have a time in the date_updated field, If the date_updated contains only a date (200/07/04 for example) it works flawlessly. What am I doing wrong? (Note that if I set the date_updated to yesterday with a time, it works also. is this a bug, or what? My logic would tell me that 2000/07/04 12:00:00 GMT+1 is smaller than 2000/07/04 11:59:00 GMT+1). Please someone tell me what's going on, I am beinning to feel that I am either asking too stupid questions, or I have problems no-one has any clue about. I am not sure what'd frighten me more... ;-) Best wishes, Nils

Problems and ponderings

Hi, In my site I have folder with subfolders and I would like to generate a menu to go to those subfolders. What I have now is: <dtml-in "objectValues()"> <dtml-var sequence-key> </dtml-in> which gives emptynes.. I've tried all kinds of combinations, tricks from the tips and howto's, but nothing. Actually I start thinking that zope is not for me. Yes, I'm a programmer, but here and now creating websites. I want to create a website, not publish objects. An abstactionlayer between zope and python would be a good thing. (and don't tell me DTML IS an abstractionlayer. It confuses the matter, it doesn't simplify. Including perl straight into the pages would be simpler. Not to mention that Python is actually decently documented..) Anyhow, I'm not giving up yet let's check my mental image: A zope site is an tree of objects, objects inherrit from parents. (how do I check if a parent exists?) so there should be a way to refere to the parent (PARENTS[]) to refer to the current object (?). I guess there should also be a way to refer to objects in an other branch of the tree (I would like to have a tools folder which is also searched when asking for a DTML-methode) Is my mental image to limited? Does it need adjusting? Gerhard

Aquisition of objects with strange names
by Oleg Broytmann 05 Jul '00

05 Jul '00

Hello. The subject seems to be broken, or maybe I just misunderstand something. Site http://sun.med.ru/pcgi2/zope.net.ru/ has some objects with ids that contain spaces, hyphens, dots - pretty non-standard chars. In most aspects these objects behaves good, but sometimes I have problems. In the root of ZODB (ZODB, not the site) I have a folder Russian-DateTime. In the root of the site I have a header that uses the folder: <dtml-with Russian-DateTime>. The root is rendred pretty fine: http://sun.med.ru/pcgi2/zope.net.ru/ But subfolders are not rendered: http://sun.med.ru/pcgi2/zope.net.ru/Zope/ AttributeError: __call__ This happens with all such objects. I have Image rounder.gif (dot in the name). I have ZStyleSheet main.css. All these objects do not render in subfolders :( The workaround is <dtml-with "_.getitem('Russian-DateTime')"> - with this the site works as designed, all objects are rendered Ok. Anyone here can explain what is going on? Is it a bug or a feature that I do not understand? Both Zope 2.1.4 and 2.2.0b3... Oleg.

What I have now is: <dtml-in "objectValues()"> <dtml-var sequence-key> </dtml-in> which gives emptynes.. I've tried all kinds of combinations, tricks from the tips and howto's, but nothing. [rh]First, why do you use sequence-key? Use sequence-item instead <dtml-in "objectValues()"> <dtml-var sequence-item> </dtml-in> second Actually I start thinking that zope is not for me. Yes, I'm a programmer, but here and now creating websites. I want to create a website, not publish objects. An abstactionlayer between zope and python would be a good thing. (and don't tell me DTML IS an abstractionlayer. It confuses the matter, it doesn't simplify. Including perl straight into the pages would be simpler. Not to mention that Python is actually decently documented..) [rh]No one will tell you DTML is ideal,. It's meant to be a presentation language and for that it's powerful. If you want to write python inside Zope - use PythonMethods. If you really want to put perl into your webpages - there is PerlMethods coming up, that presumably can do the same as PythonMethods. Anyhow, I'm not giving up yet let's check my mental image: A zope site is an tree of objects, objects inherrit from parents. [rh]Yes, and they acquire from parents. Acquisition is a type of dynamic inheritance (how do I check if a parent exists?) so there should be a way to refere to the parent (PARENTS[]) to refer to the current object (?). [rh]current object is this() for most purposes. I do not quite get what you're aiming at. But the current object depends on the namespace and the namespace is a stack determined by parents, using acquisition. Traversing the namespace changing the current object, and so do dtml tags like dtml-in and dtml-with. The best introduction to these is probably in http://www.zope.org/Documentation/How-To/AdvancedDTML I guess there should also be a way to refer to objects in an other branch of the tree (I would like to have a tools folder which is also searched when asking for a DTML-methode) [rh]This can be accomplished (simply) by using <dtml-with "<yourobject>.<yoursubobject>"> your code </dtml-with> or more directly <dtml-var "<yourfolder>.<theobjectyouwant>()"> But there are many other methods of doing this in more sophisticated ways, depending on your needs Is my mental image to limited? Does it need adjusting? [rh]it may need adjusting in your appreciation of Zope flexibility Rik
