There are several ways to make an object traversalbe, or another way of putting is is: ZPublisher tries several different traversal mechanisms in this order: Example URL: /my/ding/aling/ call __bobo_traverse__: my.ding.__bobo_traverse__(request) If the object 'ding' does not have a __bobo_traverse__ method then ZPublisher tries: getattr: my.ding.aling (note: '-' is illegal in a python name, so this first method obviously wont work for a date with dashes in it) If this fails with a 'AttributeError' exception, ZPublisher tries: getitem: my.ding['aling'] (this would work for items with '-' in them) If this fails, ZPulisher gives up and raises a 'NotFound'. -Michel > jkh > > > _______________________________________________ > Zope maillist - Zope(a)zope.org > http://www.zope.org/mailman/listinfo/zope > > (For developer-specific issues, use the companion list, > zope-dev(a)zope.org - http://www.zope.org/mailman/listinfo/zope-dev ) >

Preparing data for Catalog
by Kevin Dangoor 23 Apr '99

Hi, The catalog feature will gracefully solve a number of problems for me. Between now and the time that the Catalog stuff starts to appear, I'd like to start populating my ZODB with new information. Since my whole intent is to use the Catalog feature, I want to be sure that I'm setting things up well for that... I am planning on storing most of my information as Folder properties. Given a bunch of Folders with information stored as properties, will we be able to easily set up indexes for those properties? Is there something else we should do to ready our data for this feature? Thanks, Kevin

Hi, First: Thanks to all who have replied to my question of 'Why using Zope'. Second: Others, who still want to reply. Please do! It can only help to improve me. Ok, For what I understand, Zope will get better and better every time. :-). I've a Windows background and I program in Delphi (does somebody of you know that language?). I started with Linux one month ago and then found out about Zope. Glad I did! My only other question is as follows: I believe ZTables is database with some pretty good capabilities. I'm only wondering if it also has some sort of exchange link. Like, an ODBC-driver or something like that. This would make me help to program some stuff and use the data in ZTables too. Regards, Tom.

Re: [Zope] not to acquire from parent

I'm not sure if this is what your looking for, but if an object >is not aquired, then it's not wrapped, if it's not wrapped, then it >doesn't have the attributes aq_base, aq_self, and aq_parent. So: > > > Then it's not an aquisition wrapped object > >This help? Thanks for your response. Nope, it doesn't help. Let me explain this better: My sidebar provide content taken from acquired tinytable from the toplevel. This works great, but sometimes, I want to modify the content *only* for a folder but not for its subfolders. So, I wanted to test the existence of a local_tinytable in the current folder, and if it exists, use it instead of the acquired tinytable. I couldn't manage to do this in DTML. I had to write this external method: def not_acquired(self, objectname): self=self.aq_base try: getattr(self, objectname) return 1 except: return None Note that this external method has to be called from a DTML Method so that self is the containing Folder. This works, but I'd like to use as few as possible external methods. Thanks, Jephte CLAIN Service Informatique CHSR

Can somebody tell me where I can find emacs for linux and NT? And perhaps the EFS also?

We call these Hierarchies for obvious reasons. It comes from a very early experience in needing to allow users to browse large numbers of automotive advertisements. We could store the ads in one database (the grand dad of ZTables) and create several Hierarchies. For example, you might want to browse starting my price: Price Band Make Model or maybe you were Make drive: Make Model Price Band Sooo, one might create some fields to store the FAQ's placement and then create Hierarchy indices on those columns. An added bonus is that "flat" searching (e.g., Make=Chevrolet) will use the index data structures created by either of the Hierarchies above. > > > > I leave the floor to Martijn Pieters, our Z Tables > > > advocate, or anyone > > > > else who wants to answer.

Also, does Emacs' HTML mode handle DTML well? Long discourse here. Warning: I'm not a talented Zope developer, not a talented developer of any kind, and not a horribly sophisticated Emacs/XEmacs user. I love Emacs. I'm using XEmacs a lot these days, but I'll just say Emacs. I've badgered Amos for two months now about getting EFS support working -- for me, Nirvana would be editing Zope directly from Emacs. Why is it so cool? Let me describe how it works first for those that don't know Emacs or ange-ftp/EFS. Yesterday I ran ZServer from my sandbox and fired it up with HTTP on port 9211 and FTP on port 9210. I then went into XEmacs and asked it to open the "directory": /someuser@somemachine#9210:/PaulStuff/ provided my login information stored in an acl_users folder and blam, there was a "directory listing" of all my stuff. I visited a test.html file, it loaded into a buffer and HTML mode turned on, colorizing my tags. I made a change and saved the "file". I then went into Netscape, pressed refresh on test.html and saw my changes. Beyond that it gets cool. You can mark twenty things on your hard drive and load them into Zope or vice versa. Presumably you could copy things from one Zope to another. You can use the excellent diff tools to see changes between a local version and a remote version or apply a patch sent to you by someone. If you make a mistake you can go into Zope and undo the changes. Ultimately there are some deep flaws with this. First, it's still FTP under there. FTP is security challenged, but more than that, it isn't an object system. How, via FTP, would you add a property to a folder? Change the security? Indicate a DTML syntax exception? Review the posts in a discussion folder? FTP is not part of the "web object model". There are some other "gotchas" as well. The current DTML syntax does not lend itself to playing nice with HTML editing modes in FTP clients such as Emacs, Dreamweaver, etc. Anyway, that's some of my thoughts on the subject. --Paul

Unfortunately no, and I can't see one on the horizon. Writing ODBC drivers is painful beyond all recognition from what I'm told. A more realistic idea couple of ideas would be to implement an ADO interface. Alternatively, create a Delphi object that embedded Python and some various Zope "clients", such as WebDAV, Z RPC, XML-RPC, etc. --Paul
