zIRCon is now IRCGate
by Carlos Neves 12 Dec '00

12 Dec '00

Since Ty Sarna pointed out that there is another thingy out there labeled as Zircon, I have changed the products name to the original project ID, IRCGate. Yes, I know, I should have checked. (oops, I did it again ;) ) Thank you, Ty Sarna, and my apologies to anyone who already got zIRCon. -- "Kill processes, not people." - Larry Cohen Carlos Neves cneves(a)ruido-visual.pt

ANNOUNCE: Zope 2.3.0 alpha 1 Documentation Release
by Michel Pelletier 11 Dec '00

11 Dec '00

On the heels of Brian's announcement, we are gurgling with joy to announce a sychronized release of the Zope Book for the Zope 2.3 alpha release. http://www.zope.org/Members/michel/ZB/ This release marks the first time the book and Zope are "in sync" enough for you to be able to fully try out all the examples and understand all the concepts. This also marks the first time in long time that Zope has a (fairly) complete, up-to-date manual! Truely exciting times are these. Remember though, both the software *and* the manual are alpha, they both will have bugs. Please report any bugs, suggestions, or comments in the book to docs(a)digicool.com. Happy reading! -Michel

Hello, I tried to add a Gadfly Database connection to my Zope installation without changing any of the parameters and got an error message saying: "The parameter, connection, was omitted from the request." . What, if anything, am I doing wrong? -josh zeidner Brooklyn Media Labs, LLC. _____________________________________________________________________________________ Get more from the Web.

Announce: IRC client for zope (alpha)
by Carlos Neves 11 Dec '00

11 Dec '00

Hello, I have just uploaded to http://www.zope.org/Members/neli/zIRCon a development version of my zope IRC console product. The reason I post it in this alpha state is so that the shining minds around there might have an idea on how to solve a tiny problem I'm having... I hang on to the socket connection waiting for feedback from the server, so that things feel like real-time. But the 10 secs I wait before automagically refreshing and, therefor, releasing for moments the socket just seem too much when I'm hangin on to ALL the channels medusa makes available, rendering the zope install a bit too slow on the 'waiting for reply' state. Anyway, it works with some limitations, wich are not documented (yet). But the raw bases are all there and the code is (slightly) documented. Hope you can find some time to have fun with it and *please* send me your feedback on that socketing issue. -- "Kill processes, not people." - Larry Cohen Carlos Neves cneves(a)ruido-visual.pt

confused about folder methods
by Robin Becker 11 Dec '00

11 Dec '00

Why is it that I can use http:/F/objectIds, but not http:/F/objectItems? F is a folder. I have a ZClass derived from ZObject, ZFolder and find that I can use objectIds, objectItems etc in dtml methods of the class. Now with a class derived from ZObject, ZDTMLDocument, ZFolder I find that I cannot. I can use other manage methods to add images, but I can't call objectIds on the instances etc. Is there a way to get at the base classes somehow? -- Robin Becker

by Andre Schubert 11 Dec '00

11 Dec '00

Hi, i have a question on using meta_types in my Product. My Product contains some classes that are Folder, each Folder has different meta_types. One of these Folder(Folder4) can be added everywhere. These Folder should contain only the meta_types of the Parent Folder in which he was created. Folder1(mt='a','b') Folder4(mt='a','b') Folder2(mt='a','c') Folder4(mt='a','c') Folder3(mt='e','f') Folder4(mt='e','f') Does anyone understand what i mean and can anyone help me?

Register user/login
by Gajendra Ratnavel 09 Dec '00

09 Dec '00

Is there any way to have a user login (similar to portal/login manager) but hook it in to the root acl_user list? I tried to decipher it from the above mentioned products but I can't seem to do it. As for using the above products, they are way more complicated for my use. I just need someone to login via a link to a form, and then assign a cookie. which I need to stay alive for a set period I specify.

One of the fragilities is resolved by a fix which went into Zope 2.2.3; are you perhaps running an earlier version? I just played around with cadaver (a Unix command-line WebDAV client): * Before authenticating, 'copy foo foo.copytest' fails with '403: Forbidden', which somehow doesn't trigger authentication. * 'move foo foo.movetest' triggers authentication, and then succeeds. * 'copy foo.movetest foo' then works. I can't explain this behavior at the moment :) > > Lastly, where are properties that can be set and put using > webdav. Are these object attributes?

Significance of the ZODB split?

Anyone know why AM Kuchling needs to split off a Sourceforge project based on ZODB? I really liked the ZEO examples, but where's this going? -- Robin Becker
