Extrange behavior with numeric datatypes and decimal places
by Luis Mariano Luporini 11 Aug '03

11 Aug '03

Hi list. I'm having a problem using the following: - Gentoo Linux - Zope 2.6.1 - Python 2.1.3 - psycopg 1.1.2 - zpsycopgda 1.1.2 - Postgresql 7.3.3 The situation is I'm trying to get a number (result of a division) rounded to two decimal places and can't get it to work. After some research, my problem can be simplified to this: If I run the query: select 3::numeric(10,2) in psql I get a result of 3.00 (normal and expected behavior) in zope I get a result of 3.0 (why just one decimal place?) How can I get around this. Is this a bug in psycopg or something like that? Anybody experienced this? Thanks in advance.

Re: Zope File Library help

Zope Help System > API > File, ObjectManager is all I needed. Also, I'm copying this to the list, so that others can see. It's probably best to send things to the list, too. I might have been on vacation or hit by a bus or something. --jcc fyi, the second example can probably be shortened to:: if obj = container.Files[file.filename]: obj.update_data(file) else: container.Files.manage_addProduct['OFSP'].manage_addFile(id='', title='', file=file) -- "My point and period will be throughly wrought, Or well or ill, as this day's battle's fought."

Re: [Zope] parameter transfer to a zsql-method (lists, dictionaries etc.)
by Elena Schulz 11 Aug '03

11 Aug '03

Hi JCC, >I think your parameter construction is wrong. You're telling Zope that a list is a string, and furthermore, to iterate over a string, which won't work. In the ZSQLGuide I've got it says that ids:list:int indicates that ids is a list of integers. So columns:list:string should mean that columns is a list of strings. But even columns:list didn't work. After further investigation I think the parameter-parsing of zsql-methods is quite restricted and it's better to pass "complicated" structures via a single dictionary. I'll try that. But still I would like to know how it would work with lists and dtml_in constructs. Anyway some complete examples including the parameter part would enhance the ZSQLGuide a lot. -- anyway thanks for your answer, Elena

Sessions between domains
by Ben Bush 11 Aug '03

11 Aug '03

I have one web server that I am using with zope running on the same box. I want to know how I could transfer session info from one url at www.domain.com to my secure site at secure.domain.com. As far as I can tell, I don't have access to the same session data. This is for a shoppping cart app that would have a user back and forth but I want to maintain the contents of the cart no matter where they may be. Thanks, -- Ben Bush Center 7, Systems Administrator 801-655-2640

Now that I can access the ZODB via the python interpreter I can't seem to find the User object and its methods. The challange I am facing is that to see some of the objects in the ZODB I must be an authenticated user. I have tried both of these with no luck. dir(app) dir(Zope) What am I missing? tia, Mike
