Generic workflow
by administrator＠consotec.de 02 Sep '00

02 Sep '00

As I saw during the last days there is a big interest for generic workflow. There is an open source project called wftk: Open-source workflow toolkit (http://www.vivtek.com/wftk) Currently it's Tcl/C based with XML as description language. Maybe we could pull together our resources and finish it on a Zope/Python platform. I already contact the developer and waiting for a response. Arno Gross email: arno.gross(a)consotec.de

A ZCatalog search usually combines searches to the different indexes with an "And". You want to combine them with an "Or". There is an example for this in the Advanced ZCatalog Tutorial (--> zope.org) There has recently been a discussion in this list (--> searchable archive). Apparently, there is no comprehensive solution. Dieter

RE: [Zope] ZCatalog in 2.2.x

This is not right, obviously. Can you rebuild your indexes (by deleting and reentering them), recatalog, and see if the problem goes away? We haven't had any colluding reports of something like this, and I'm using the 2.2.1 catalog with textindexes successfully on a customer project. > -----Original Message----- > From: Terry Kerr [mailto:terry@adroit.net] > Sent: Wednesday, August 30, 2000 3:27 AM > To: pja(a)clari.net.au; zope(a)zope.org > Subject: Re: [Zope] ZCatalog in 2.2.x > > > I am not searching from a form in that sense...I am talking > about at the python > level. > > I have self.searchResults({'description':'blah'}) where > description is meta > data in the catalog and a textindex and 'blah' is in the > Vocabulary.

Plus, I have to restart my server because ZODB >reports a transactional error and sets itself to read-only. I would guess you have the same problem as Diego Rodrigo... could you check your standard_html_header? Does it make any reference to SESSION? One thing about HappySession is that I made it so no initialization is required. So please do not call SESSION object in standard_html_header to initialize it. (In the next release I'll make it safe even if someone calls it in standard_html_header.) I will try to guess what you want to do: you want to initialize FLinkID at the beginning of the session? If so, since HappySession's dictionary does not require initialization, you can do something like: <dtml-if "SESSION['FLinkID'] == _.None"> <dtml-call "SESSION.set('FLinkID', 0)"> <dtml-else> ... normal operation here ... </dtml-if> (If an item does not exist, SESSION['FLinkID'] returns ._None) regards, Hung Jung _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

Testing FastCGI

Hi, I have set up my Apache and ZOPE according to How-To. It looks okay to me. However, how can I know if my setup is correct. Is there any test FastCGI application I can simply drop it in and test out my system? Thanks Nicholas Lo

Re: [Zope] Copying a dtml method when creating a ZClass instance

Why? >aquisition should make it 'visible' in every subfolder automatically. > >Regards >Tino I have several reasons whay I need to attach a template to each ZClass. Among them are: 1/ cases like high level folders where I might want to customize the page's rendering and/or skin, 2/ cases like contained objects which uses a generic skin (but you can still customize the skin of one among them, if you want) 3/ my site needs to be easily designed / modified by Web Designers that do not understand Acquisition. Thanks for the tip Chris, I was able to do it by adding my ZClass-specific-template in the Zope Product folder and adding a call to manage_clone(ZClass-specific-template, 'standard_template', [REQUEST]) in the ZClass constructor method. I use the same id 'standard_template' to exploit acquisition globally on the site (the Web designer would not have to care about that). Next thing is generalising this method to also allow multiple templates available for each object i.e. the Content Manager can choose a prefered skin when instanciating an object.

SQL Methods
by RC Compaan 02 Sep '00

02 Sep '00

I have a sql method and a dtml method calling the sql method. They live in the same folder and the dtml method's proxy roles are set. I've tried everything and Zope tells me I don't have permission to do view the sql result returned by the sql method. This worked fine in Zope 2.1.6 so I guess it has something to do with the new security model. I also have explicit ownership of all objects that I'm working with - still no luck. Any advise? Roché

Thanks!
