Hello, Where I work, I do not have access to the internet, and as such, I have to move software and docs back and forth to my office. I understand that it is better for collaborative work to use ZWikis, but I wonder, how do I download the entire site to view it offline??? ok this is not really zope-dev, but I need the wikis to zope-develop... thanks, jephte clain minf7(a)educ.univ-reunion.fr

ZCVS Mixin class... feedback sought.

Have a little patience with Steve, to him reading Python source code is like reading our own native language to the rest of us. "Docs, we don't need no stinkin' docs!" ZCVSMixin is a sort of replacement for a standard Zope Folder Object. If you want to be able to maintain an entire Zope Folder (and everything in it) in CVS, use a ZCVSMixin Object instead. Then, from the Manage view, you get a new tab showing up that provides the interaction with CVS. What it actually does is an Export as XML on the whole "folder", which then can be stored, view, checked out, checked back in, and otherwise thoroughly managed and maintained within CVS. For developers that are deep into Zope, and familiar with CVS, this represents some potent possibilites. Think about checking out a Zope Widget from a CVS on the other side of the planet, importing as XML into your local Zope, where it is marshalled back from its CVSish XML form into the original native Zope self. Now you can tweek it to your hearts content, export as XML, then check the updated version back in, where it becomes part of the trackable, archived, searchable CVS system. Steve, please clarify any of the concepts I've managed to mangle!

DTML tag creation.
by Bill Anderson 25 May '00

25 May '00

I am about to dive into a custom tag, it will be a 'container' tag. I have seen the HowTo, and it really isn't that clear when you get to the container tag info. Can anyone provide a better rundown? Anyone have a custom tag they would mind sharing for perusal? Just trying to save myself sometime. TIA, Bill

ZWiki - how to dynamically add a page?
by Lena 25 May '00

25 May '00

Dear Chris, Thanx a lot for your suggestion. Zwiki is indeed something very helpful to me. I've got a couple fo questions, though: 1. How can I dynamically add a Zwiki page? It says there: "To create a link to another wiki page, just write its name. (If you don't use a WikiName, you must enclose the name in square brackets). If the page does not yet exist, a ? will be displayed - click it to create the new page. This is how new wiki pages are added." Where do I have to write the name?? There's a form field in the upper right corner of a Zwiki Page header, but inserting a new name there doesn't work. 2. How can I add dynamically ZWiki Pages to different folders in /Control_Panel / Products / ZWiki / zwiki_examples / folder??? Hoping to hear from you ASAP.. Lena

eat our own unsupported dog food

There is a recent need for us to install ZDiscussions on Zope.org. I have verified that 0.1.0 works with 2.1.6, but I can't seem to d/l 0.2.0. The author of said software is not available, any one know the status on ZDiscussions? Has any one tweaked it? -- -Michel Pelletier http://www.zope.org/Members/michel/MyWiki Visit WikiCentral for the latest Zen: http://www.zope.org/Members/WikiCentral

Re: [Zope-dev] Observer / Notification Interface Proposal

Note that the scaling requirement (no blocking/long-running actions inside the notification call) is intended to support intra-request notification. A ConcreteObserver implementation which needs to perform such work (e.g., send an e-mail message, etc.) will have to extract whatever data it needs from the subject and enqueue it for processing in some other thread, by the asyncore machinery, etc. Note as well that it would be possible to install an Observer which could "veto" the change by raising an exception (a clever ConcreteSubject might ignore such a veto, of course). I'm don't have any use case in mind for a cross-transaction "event". > Second, I think there should be an opportunity for the observer to > specify more detail about what it wants to be called *for*. I.e., > either a specific event or an event mask, to avoid unnecessary > calls for irrelevant events. I considered this, and decided that it would be simpler to put the EventFilter in a "shim" object (e.g. a high-pass filter) which would sit between the actual subject and observer. Consider stringing together a shell pipeline, e.g.:: ps -aux | grep tseaver | ..... | sort" Each piece has a very limited set of responsibilities, but stringing them together arbitrarily conveys enormous power. I also have hopes for a set of federated, filterable NotificationChannels (like CORBA's NotificationService) which would allow Observer-in-Zope to scale up enormously. > I realize this is all very implementation oriented, but that's > me. :) > > (Oh, btw on "ObserverInterface", I'm guessing you mean the > contract requires that *observable* not worry about delays, not the > other way around.) Changed it to 'subject' -- thanks for pointing it out! Thanks for the feedback!

XML to SQL or XML into tables
by Thomas Weholt 24 May '00

24 May '00

Hello, Has anybody tried to somehow get xml-data into SQL-statements or in some other way use xml-data as datasource for insertion into tables? It shouldn`t be impossible, if we could just agree on some format or DTD to use. Ex. <xml> <data> <database name="demo"> <table name="users"> <row> <field name="user_name" value="thomas" /> <field name="sex" value="male" /> <field name="programming_language" value="python" /> </row> <row> <field name="user_name" value="bill" /> <field name="sex" value="male" /> <field name="programming_language" value="java" /> </row> </table> </database> </data> </xml> This means the demo database and the table users allready exists of course. Any thoughts? I know this could at least sort out alot of troubles I`m having right now getting data from external sources into Zope. I`m going to try and make a product or a method etc. that uses xmllib doing this, but if anybody has done it allready I`d be very happy do "abuse" their effort. :-> Thomas

Problems with LoginManager form-based login
by Itamar Shtull-Trauring 24 May '00

24 May '00

I add a folder, with a LoginManager in it, define Cookie Auth as only authntication. Now, every time I try to view the folder I get the loginForm asking me to login, even though Anonymous has permissions to view the pages. If I delete the loginForm this doesn't happen, I can view the page with no problems. How do I get the loginForm to appear only if the user doesn't have enough permissions? -- Itamar S.T. itamar(a)maxnm.com
