Hi All Thanks for the feedback. Progress of a sort <g>. Using "http://127.0.0.1:8080/manage" I still get the IE error report but I also get the following debug response to start.bat: Traceback (innermost last): File "C:\Program Files\WebSite\z2.py", line 621, in ? logger_object=lg) File "C:\Program Files\WebSite\ZServer\HTTPServer.py", line 391, in__init__http_server.__init__(self, ip, port, resolver,logger_object) File "C:\Program Files\WebSite\ZServer\medusa\http_server.py", line 549, in__init__ip = socket.gethostbyname (socket.gethostname()) socket.error: host not found Seems to be a variant of the IE error report so I'm no further forward unfortunately. Regards jaygee ----original message---- > I'm unable to open Zope 2.3.0 on my pc under Windows 95.

ZSQL: UPdating a db entry with data from a query
by Gitte Wange 05 Apr '01

05 Apr '01

Hello, I need to update a entry in my database with a rownumber minus one Okay I do this: <dtml-in FindTheRecord> <dtml-call UpdateTheRecord> </dtml-in> Now the FindTheRecord returns a record with a unique id-field. So I use this field to update the record with but gets this error: Error Type: Bad Request Error Value: ['id'] My sql for the methods looks like this: FindTheRecord: arguments: ordernum SELECT * FROM playlistclips WHERE ordernum=<dtml-var ordernum>-1 This one works in test Update the record: arguments: ordernum id (these are taken from the above query and are fields in the above query-table) UPDATE playlistclips SET ordernum=<dtml-var ordernum>+1 WHERE id=<dtml-var id> Now I don't see what's wrong in doing this but Zope is :-) Regards, -- ************************ Gitte Wange Jensen System Squid Developer MMManager Aps +45 29 72 79 72 gitte(a)mmmanager.org ************************

Sorry it is something I made, Additionally, upon further testing, although it will change a users data (if submit ='Change') or add a user (if submit='Add'), it doesn't delete a user? go figure Zope documentation is incorrect.

Re(2): Re(2): [Zope] Cascading Style Sheets in N etscape 6

>Try having it validated by the W3C checker... Lemme dig out the url: > >http://jigsaw.w3.org/css-validator/ I tried that, but the only thing it seemed to object to were my <dtml-var>s which I expected anyway. >Can you possibly provide us with an example? Sure. In my CSS I have set up this variable: .OAA { background-color: green; font-size: 20pt; font-weight: bold; color: gold; font-family: Arial, Helvetica, sans-serif; font-style: italic; } I refer to it in the code of my <standard_html_header> as: <TD class="OAA" align="center">OUTDOOR ADVENTURE ACTIVITIES</TD> Works fine in Netscape 4.75, but not at all in Netscape 6. I have created other similar variables and Netscape 6 doesn't recognise any of them. The only part of my CSS is does recognise is: <dtml-call "REQUEST.set('site_fonts', 'Comic Sans MS')"> It does set Comic Sans MS as the default font, but refuses to recognise any of the variables I set up in my CSS. Any ideas what the problem is? ------------------------------------------------- Craig Stoddart IT Software Development Officer Dundee City Council IT Division Northern College Technical Block Gardyne Road Dundee DD5 1NY Phone: 01382 438170 Fax: 01382 438002 E-mail: craig.stoddart(a)dundeecity.gov.uk -------------------------------------------------

Can I stop processing while saving data?
by Shai Berger 05 Apr '01

05 Apr '01

Hi guys, Problem: In our site, there are some pages that require that a user be logged in. We implemented a login mechanism using sessions, and we do not use Zope authentication. Now, in order to make the maintenance of this manageable, we used a property, called "LoginRequired", which is checked by our standard_html_header. If a user tries to access a document which has this property set, without being logged in, we redirect her to the login page. The thing is, it is very convenient to assume, while developing, that if you set the "LoginRequired" property, a user executing your code is logged in; thus, the code in many places assumes things like a user_id in the session data. This, in turn, means that if the redirection is done with RESPONSE.redirect, a Zope Error will occur in the processing of the page. What we really want to do at this point is just stop the processing -- and we can do that by a <dtml-raise Redirect>. The tricky part is, that an intelligent site, once the user has logged in, takes her to the page she asked to see in the first place. For this, we need to keep some data -- like, where she was going, so we can redirect her there after she logs in; and the natural place for such info is in the session. But raising an exception (like a Redirect) causes all data changes to be rolled back, so we have a problem. Up to now, we have been using SQLSession; there, we could force a database commit before raising the Redirect exception. This is an ugly kludge, but it worked. Now we want to switch to CoreSessionTracking, and I see no nice or kludgey way to do it there. Any ideas? Thanks, Shai.

Re: [Zope] RE: [ZCommerce] RE: Philip leaves Arsdigita (was: Re:[Zope]kerberos ? + LDAP + ecommerce + ZEO replication etc)
by Richard Volpato 05 Apr '01

05 Apr '01

I am new to this list. I had been seeking insights and tools to run zope with ecommerce. The blend of zope with OpenACS ecommerce seems just right. Maybe DC need not do it, but it seems obvious to me that it should * encourage and direct * such a project. Current projects do not seem up to it. Albert Langer seems keen on (even zealous) about the project - co-opt him in some way, if you have to. E-commerce is an application. But the OpenACS version makes it an 'infra-structure' for community building. This 'community enabling infrastructure' (Open)ACS really understands. It's an understanding embedded in its SQL. They know how to transform a 'customer' into a 'member'. I see no evidence that the zope community understands this deep wisdom about the nature of e-commerce as a 'collaborative co-production' rather than a simple transaction. Ironically, zope seems ideally suited to leverage this wisdom and its tools. In particular, from interview comments I noticed from Paul E., the zope people really understand the value of meta-data and collecting it 'on the fly'. It is a small step to extending the source of 'meta-data' from users and documents to *fellow*-users and *linked* documents respectively. This gets you to 'collaborative filtering'. It's also a small step for the resulting 'customers - cum - members' to access e-commerce in order to buy documents and services found within the trusted environs of their digital 'community'. Inevitably, Zope will need ecommerce - content management with 'delegation', meta-data, dynamic publishing etc *without* an e-commerce infra-structure seems misguided. It's probably a mind-set: meta-data, dynamic publishing,etc involve web applications and server technologies, not so much industrial strength transaction databases. Postgresql with its enhancements means Zope could offer a new vision about transacting on the web, just like it has on publishing on the web. To simply think 'e-commerce' is just some business 'extra' is to be missing the wood for the trees. Strike now! while the OpenACS developer community looks for new alliances to restore their faith in 'open-source'. For my part, even an announcement that DC was 'investigating' would be enough to convince my clients that this would be the way to go - thus getting some resource to help in the effort. I can't be alone in this. Richard Volpato

Xron on Zope v.2.3.1
by Spicklemire, Jerry 05 Apr '01

Chris mentioned: > Something Loren e-mailed me a few weeks ago spurred me to check the > permissions Xron has as it runs--it basically runs as an anonymous user and > has to have a proxy permission setting in order to perform certain > operations. This doesn't apply when you're logged in and triggering the > method since it's then running as "you." Good idea! I'll double check Xron's proxy setting and make sure it's set to "manager". Thanks, Jerry S.
