Yes. It's now crashing if I pass *any* named parameters.

The only part > of my CSS is does recognise is: Two things spring to my mind: 1) I heard that Netscape does not like spaces in the definition of stylesheets, especially around the colon. 2) Some versions of Netscape require JavaScript to be enabled to handle CSS, I don't know if this is true for version 6. hth werner -- GMX - Die Kommunikationsplattform im Internet. http://www.gmx.net

Site Root alternatives ?
by Bernd Dorn 05 Apr '01

05 Apr '01

Hi everybody Is it possible to rewrite urls created by zope in a specific folder without putting a site root into this folder. The reason why i need this is that I don't want the manager of this subfolder(site) to see the siteroot object in this folder. I've got an Apache with proxypass running in front of the zope installation. Maby there is another way to code many virtual hosts. I think of a method which rewrites urls to a specific property of a folder or so. thanks in advance

Re: [Zope] keeping zope running after closing ssh conection

Probably, it already helps to start Zope without the "-D" (debug mode) option. If it does not or you want the debug mode, then certainly a "nohup" (--> man nohup) will help. Dieter

Re: Zope 2.3.0 Under Windows 95

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.

>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.

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.
