WebDAV configuration
by Mary Thompson 29 Jun '99

29 Jun '99

I want to configure a folder called "Projects" on my Zope 1.10.3 site for WebDAV. I got that client program, DAV Explorer, and want to use it to connect to Zope. It should be pretty simple, right? I can't find any explanations on configuration on the Zope web site. Also, I went to search this e-mail archive, and it's down. It's the third time I've tried to search it in 3 days. I wish I could just look stuff up there. Thanks for your help, Mary Thompson

It >would also involve up coming up with a few of our own Content Types. A way that I solve a similar problem in my ZPublisher-based application engine, is for container-ish things to have a "ClassMaps" attribute (which is a cumulative multimapping of its parents' ClassMaps, plus its local mapping) that maps file name fragments to class information. When I need to know the type of a file, I look up: * The entire filename plus '/' if it's a directory (or a MKCOL/MKDIR type operation) * The filename as is * The longest possible file extension (e.g. ".tar.gz" before ".gz"), with a trailing /, if applicable and then without. * Successively shorter file extensions, with and without the / Proceeding until a match is found. This approach lets me do things like make an entry for "CVS/" so that CVS directories are automatically assigned an appropriate class, and I can distinguish between a name or extension used for a file vs. the same used for a directory. Of course, I'm using this to access an actual filesystem rather than to handle FTP/WebDAV. And in Zope this would be further complicated by the need to manage content types. Last, and worst (from my POV anyway), is that Zope has no way to drop off the extensions so that URL's can remain polymorphic (i.e., an object's name has nothing to do with its type/implementation). In my file-driven engine, object id's do not include the file extension but are resolved polymorphically. If foo.html becomes foo.dtml, the URL is still 'foo' and no part of the system really cares except that object's implementation. Of course, Zope could use the multimapping approach in the opposite way from how I do it, and instead ADD the filename extensions when operating in FTP/WebDAV mode. So 'foo.sql' in that mode is really 'foo' in regular Zope. But I'm probably just muddying the water further at this point, so I'll shut up now. :)

RE: [Zope] Sessions needed
by TFE MMS JARVIS JOHN 29 Jun '99

It might not satisfy all of your wishes, but... You could use the CookieCutter to do this if you're fine with storing pickled information in cookies. Basically, it pickles a dictionary of objects into a cookie and provides an easy-to-use interface for settings and programming. My application involves some complex queries and saves the user's search selections on the client so they don't have to enter them with each session. I quickly ran into the cookie number limit and needed a way to consolidate the information into a single cookie. I didn't want to go all the way building a database to store the data. You can download it from the Zope contributed products page. BTW, there is also a version of the CookieCutter with MD5 checksums for security added by Mark Hays. I got really busy and never updated the version on the Zope Contrib page. I owe Mark an apology for that. Sorry! If it's ok with the DC guys, should I post it separately? I don't know how this is usually done. Anyway, give it a lookover--it's an easy read ;^) John Jarvis > -----Original Message----- > From: michel(a)digicool.com [SMTP:michel@digicool.com] > Sent: Monday, June 28, 1999 11:46 AM > To: Frank Buhr > Cc: zope(a)zope.org > Subject: Re: [Zope] Sessions needed > > Frank Buhr <buhr(a)kogs1.informatik.uni-hamburg.de> writes: > > > Hi, <SNIP> > > > Has anyone build a nice Zope product which does this? > > > > I believe there is a product somewhere out there that lets you > manipulate cookies in the browser to store some small amount of state > (something like 4K) on the client.

Instance methods overiding Class method
by Service Informatique CHSR 29 Jun '99

29 Jun '99

Hello, I wonder if the following is the intended behavior or it is to be fixed: I create MyClass which inherits from Folder. I create MyFolder, instance of MyClass, and I create a MyMethod DTML Method in it. *Then* I create a DTML Method named MyMethod in MyClass. Newly created MyClass instance won't let me create methods named MyMethod in them (object already exists). However, http://mysite/MyFolder/MyMethod displays the content of the first method (instead of the MyClass method). And now the funny part: if I delete MyFolder.MyMethod, it is not possible to "Undo" the deletion: the transaction is not is the list anymore, but MyMethod doesn't get recreated in MyFolder. Sincere-ly yours :-) Jephte CLAIN Service Informatique

What I'd suggest is using ZServer's PCGI server, and adding an option to the PCGI server to tell it to chop a given string from the PATH INFO.

I don't really follow this, but ZServer's PCGI server can and does in fact munge the PATH_INFO to get around an IIS bug.

To configure ZServer read the ZServer/README.txt also run the start script with the -h option: $ python z2.py -h Here's a totally untested patch to PCGIServer.py to accomplish this PATH_INFO munging.

> Is there a way to prevent ZServer from saving all docs as dtml docs > instead of as dtml methods, when editing with xemacs/efs? Not currently. This has been discussed before. There should probably be some better system for sniffing uploaded content and trying to figure out what sort of Zope object to create. This could be based on * file extensions * http headers * the content of the uploaded object * Zope preferences This is a fairly complex problem. For example, there should be some way for you to specify that uploaded files with a given file extension create instances of a given Z Class. Hmm.
