Hm - the goal I had for Hotfixes was to address imperative problems that couldn't really be addressed any other way. I'm not sure that this _quite_ makes the grade in my opinion (but I could probably be convinced). For example, a security problem _demands_ a hotfix-type solution because you can't tell the crackers out there "dont do that!". In this case, there is a clear way to avoid the problem that *is* under your control and a clear way to recover in case you forget :) I also want to make sure that Hotfix releases instill a sense of urgency in people - while there are lots of things that *could* be packaged that way, I worry that doing this when its not absolutely necessary can cause "hotfix fatigue" where people might stop paying attention to them over time.

Sql result searchs with Z Catalog
by asjf11＠uaa.alaska.edu 06 Jul '00

06 Jul '00

I need to somehow populate an ZCatalog index with the results of a Z SQL Method. If you are familiar with ColdFusion, it needs to have the same functionality as a Verity search on a collection (custom indexed from a query). I am having trouble seeing how this might be accomplished. Thanks, Jake Feasel

Web site newbie
by Montagne, Michael 06 Jul '00

06 Jul '00

I'm very excited about learning Python and Zope. I'm a win98 user and just today upgraded my service with my ISP to host my web page from home. So I need a web server. According to the docs, Zope comes with one. If I use that one, am I going to be over my head initially? Should I be using a different product if my site is not going to be super dynamic from the beginning? If I use Personal Web Server, can Zope be integrated later? Can I use Web authoring software such as Front Page 2000 and publish to Zserver? thanks so much, -mjm

File referencing and LocalFS
by Rogerio Atem de Carvalho 06 Jul '00

06 Jul '00

I am using LocalFS to refer to a directory structure like this: folder1 | folder11 There are image (.jpg) files in both folders. I have two questions about this: 1)Folders names are directly related to string fields in a MySQL database which use spaces between words (eg New York), but folders names don't use spaces (eg NewYork). How can I skip spaces from database fields to make them refer to these folders (eg New York --> NewYork)? 2)Using LocalFS, can I do something like <dtml- var "localfsObject['<dtml-var par1>'].['<dtml-var par11>'], where par1 and par11 are folder names (after skiping spaces)?

How do I merge form & URL vars into sql easily
by asjf11＠uaa.alaska.edu 05 Jul '00

05 Jul '00

I am a new user to Zope and I'm trying to pass data that has been entered into a form (either through GET or POST) into another object. This object calls a z sql method to insert the form data into the database. So far, the only way I've found to pass data to the sql is to define arguments for it and then, in the dtml-document (or method) use: <dtml-call "REQUEST.set['argument','value']"> (and it took me long enough to figure THAT out, let me tell you) The problem is that sucks when there are 30 form varibles that need to be inserted into the database. I would think that there is some way to let the sql method see these varibles that are defined within my document. Or loop through all URL or form varibles defined and sets all the vars in request. Something to keep from having to write the above dtml 30 times. Thanks. Jake Feasel

RE: [Zope] Authentication, Anonymous and Public
by Capesius, Alan 05 Jul '00

Brian, here are the steps to recreate: Caveat: Anonymous is unrestricted at the root level 1) Create a folder 2) Remove inherited (acquired) rights for all attributes 3) Add a user to the folder 4) Give the user the manager role 5) Access the root level using a restarted (clean) browser to confirm accessibility 6) Access the new folder created in (1). You should be prompted to login. 7) Login using the new user account 8) Now try to access the root level again. You should be prompted for a password.

Lists and external methods
by Pieter Claerhout 05 Jul '00

05 Jul '00

Hello there, I started working with Zope a few days ago, and I'm currently having some troubles with external methods. I made an external method that returns a record like list, but this doesn't seem to work correctly> The list look a bit like this: 90, "x86", "Explanation", "22/06/200" 89, "x86", "Explanation", "22/06/200" 89, "mac", "Explanation", "22/06/200" I want the external method to return this in a list, where I can iterate over using the <dtml-in> tag, so that I can reference the different fields in each record with a name. What should the list look like so that I can accomplish this? Pieter
