% in Z SQL Methods

Using the dtml-sqlvar syntax is it possible squeeze in a % sign in the expression? Today I use this syntax: WHERE firstname LIKE '<dtml-var firstname>%' Peter

Python Product variable problems
by kosh 25 Feb '01

25 Feb '01

I have a python product and all of the variables that define that object are in a dict as part of the class. My problem is that when I add new variables to that dict for new features the objects already in zope don't get them. I do need the objects to be persistant but was wondering if there is some method I can add which would auto update objects on view, edit, etc if a newer one existed. Thanks

How to create a folder for a given user ?
by Emmanuel Viennet 25 Feb '01

25 Feb '01

Apologies for these simples questions... What is the correct procedure to follow in order to create a Folder owned by a given user (ie I want to create the equivalent of a unix account with a home directory). By the way: in the (near) future I'd like to automate this task (using XML-RPC or some other scripting technique). Where can I find a documentation of the API (I didn't find informations about user creation, ownership change etc in the Zope Book nor in the QuickStart help). Thanks, Emmanuel -- Emmanuel Viennet Dpt GTR - IUT de Villetaneuse - Universite Paris-Nord 93430 Villetaneuse - France http://www-gtr.iutv.univ-paris13.fr/

Owner, or not owner ?
by Emmanuel Viennet 25 Feb '01

25 Feb '01

I'm playing for the first time with Zope 2.3.0 (I have an old site running happily since 18 months Zope 2.1.4:-) I try to setup a site with several authors, each owning its folder. The users are defined at the root (/acl_users). The folder "Team/foo" belongs to the user "foo". In this folder, I grant the permission "View management screens" to the role "Owner". Problem: user "foo" can't manage its folder. If I grant this permission to "Anonymous", it works... In the ZopeBook, we read "Owner: This role is assigned automatically to users in the context of objects they create.". What did I missed ? Thanks for your help or for pointers to relevant documentation. -- Emmanuel Viennet Dpt GTR - IUT de Villetaneuse - Universite Paris-Nord 93430 Villetaneuse - France http://www-gtr.iutv.univ-paris13.fr/

I fear, the new Zope security model will not support this. Afaik, the only method to change ownership is "takeOwnership". > By the way: in the (near) future I'd like > to automate this task (using XML-RPC or some other > scripting technique). > Where can I find a documentation of the API > (I didn't find informations about user creation, > ownership change etc in the Zope Book nor in > the QuickStart help). The most relevant object is the UserFolder (defined in "AccessControl.User"), usually called "acl_users". You can look into the sources or use my DocFinder product. Dieter

Reformatting a date string?
by Miro Jurisic 25 Feb '01

25 Feb '01

I'm just starting to play around with Zope, and I can't figure out how to take a string containing a date/time (I'm getting it from an SQL query) and print it in a different date/time format in DTML.

Accessing objects given an URL (was: [Zope] FW: Reading properties from nested objects.)
by Dieter Maurer 25 Feb '01

25 Feb '01

Michael Van Cleave writes: > ... > I cannot figure out how to use > the stored absolute url to read elements off the remote object. If the URL describes a physical path, you can use "restrictedTraverse" (-> Zope API -> ObjectManagerItem). If you are using virtual hosting and the URL describes a logical (i.e. virtual) path, then "REQUEST.resolve_url" is the correct method. Dieter

multipart pushing

Howdy Zopistas! I'd like to implement a chat function using the multipart content type and I wonder if that is possible with Zope. My idea is to write a python script that pushes the content of a database until e.g. the stop button is pressed in the Browser. But how would the script know that it's supposed to stop? And would such a longtime connection completely occupy one Zope thread so that I'd have to increase the number of threads? Ragnar
