This may have to be something as clumsy as a control panel toggle to the FTP behavior, I don't think there is any way for Zope to know that you intend the text to be a Document or a Method. If you can brainstorm up a better solution that a toggle, let us know. -Michel > Alex Rice | alrice(a)swcp.com | http://www.swcp.com/~alrice > Current Location: N.

zcatalog always catalogs whole site when using 'Find' tab.
by Anthony Baxter 30 Jun '99

30 Jun '99

first off, the ZCatalog tutorial has a chunk that includes example HTML, without quoting it - search for 'Replace it with this:', it's the line before and the line after. next thing - if I add a ZCatalog to a subfolder, and do a 'find into catalog', the search will start at the top of the Zope tree. This seems unintuitive to me - it should only do the find from the folder object containing the ZCatalog. (This is more in keeping with the behaviour of the existing 'Find' tab) the following will change ZCatalog to have this behaviour: --- ZCatalog.py Wed Jun 30 15:00:23 1999 +++ ZCatalog.py.orig Wed Jun 30 14:56:10 1999 @@ -248,11 +248,11 @@ obj_permission=None): """ Find object according to search criteria and Catalog them """ - results = self.ZopeFind(REQUEST.PARENTS[1], + results = self.ZopeFind(REQUEST.PARENTS[-1], obj_metatypes=obj_metatypes, obj_ids=obj_ids, obj_searchterm=obj_searchterm, obj_expr=obj_expr, obj_mtime=obj_mtime, Does this seem reasonable? Or should it be a checkbox in the 'Find' page to specify whether to search the entire site? Anthony

Not quite as flexible as an isinstance() method, but could be handy. -Michel

Squishdot is based on a much earlier and simpler Digital Creations product (now unsupported) called Confera. Butch Landening (I hope I spelled you last name right Butch) used confera as the basis for the very impressive Squishdot, which is a weblog. Confera is a discussion board product that was written in the pre-weblog days, and it happened to have a nice messaging core which Butch used for the message store in Squisdot. In addition, Butch prettied it up mightily and added many new and cool features. Squishdot can be thought of as an out of the box solution to a Zope based weblog. The Zope Portal Toolkit on the other hand, is, as its name implies, a collection of Zope products and Zope infrastructure components that allow content developers to easily develop sites which employ such features as Membership (the ability for users to contribute in a distributed way to an entire site's content) site wide searching, issue tracking in a sensible workflow environment, and other features. We anticipate Squishdot, with little modification, to be an important community contributed component of the Zope Portal Toolkit. As an example, you can use the ZPT's membership to allow your students to have their own 'home folder' where they can upload documents and files related to their projects. Site wide searching and cataloging will allow your students to search the whole site, and catagoricaly break down the various artifacts of their home folders. Squishdot will allow your students to originate and follow up on threads of discussion among the whole 'community'. Issue tracking will allow you to originate 'issues' which can then be tracked from actor to actor (think of peer review on an assignment), with the actors typicly being members, or just email addresses for 'foreign' participants. -Michel > Later, > Tim > > -- > Timothy D.

Re: difference between Squishdot and Portal toolkit

>From my understanding of the Zope Portal Toolkit, its "an easily integrated set of technologies that will allow Zope developers to build high-performance, dynamic portal sites ". My own take on this is that it provides an "infrastructure", a set of basic building blocks, that make it easy to build highly dynamic websites. Squishdot ,on the other hand, is more on the level of an "application" -- it builds on the facilities provided by Zope to give you a very specific set of capabilities to fulfill a particular goal -- a place to publish short news items and hold threaded discussions about them -- with a minimum of configuration while at the same time, be flexible enough to fulfill a wide range of new publishing and discussion needs (need to take a breath after that long sentence, hew :^)) While there are some areas of overlap (specifically, the News portion of ZPT may have the same functions as Squishdot -- but in truth, since I only have a very meagre understanding of the details of ZPT, I really don't know), ZPT covers much more ground than Squishdot. On the other hand, my intent with Squishdot is to integrate and use the ZPT where it makes sense. For example, I'm studying the ZCatalog intently to see what benefits I get if I use it as the indexing mechanism, instead of using the Index and TextIndex classes from Zope. Another thing I am excitedly waiting for is the Membership capabilities. I am hoping this would allow Squishdot to provide user customization and tracking features (i.e. membership registration,login/logout, ability to filter content based on user preferences, etc). <BLATANT PLUG> I would urge you to try out Squishdot and see for yourself whether it fulfills your needs. </BLATANT PLUG> I intended it to be easy to use and is heavily documented so you can extend it to fit your needs if it doesnt already :^). Butch Landingin butchland(a)yahoo.com P.S. BTW, its available at the Squishdot home page (members.tripod.com/squishdot/index.html) and at the Zope contributed products page (www.zope.org/Download/Contrib) _________________________________________________________ Do You Yahoo!?

Returning a binary file from an external method.
by Jay, Dylan 30 Jun '99

30 Jun '99

I have an external method that generates a binary file. The content-type I'm trying to use is "Content-type: application/octet-stream". How do I do this in zope? If the just call the method and use RESPONSE.setHeader to change to the content type it doesn't work as the content has been mangled using some sort of encoding.

Printing value based on SQL table lookup
by Michael Wang-Helmke 30 Jun '99

30 Jun '99

hi all, I have some database tables being accessed via SQL where each record is of the form (key, value). In my Zope product in development, I keep track of all information by key but for user display purposes, I want to show the value. I have SQL of the following form to do the lookups: product_list_by_key_sql(item_id) SELECT product FROM products WHERE key =  and I intended to use it in my DTML pages as follows:  where prod_key is the product key. However, this just gives me an object reference for the Database result class. With further strange hacking I came up with this  which I understandably don't like very much. (nor do I quite understand it). I am fairly new to Zope but not Python. How would others do this? thanks, Michael Wang-Helmke

RE: [Zope] Count of folders within another folder?

This works:  Note that this won't automagically include folder-like products or Z Classes descended from Object Manager. There's no objectValues() that has isinstance() behaviour (yet). So if you have any such objects, the most convenient way to do it right now is:  Hope this helps. -- Alexander Staubo http://www.mop.no/~alex/ "`This must be Thursday,' said Arthur to himself, sinking low over his beer, `I never could get the hang of Thursdays.'" --Douglas Adams, _The Hitchhiker's Guide to the Galaxy_ >-----Original Message----- >From: dyork(a)mercury.mv.net [mailto:dyork@mercury.mv.net]On >Behalf Of Dan >York >Sent: 30. juni 1999 01:09 >To: zope(a)zope.org >Subject: [Zope] Count of folders within another folder? > > >Hi all, >I've got a question that I can't solve myself... in Zope (1.10.2), I've >got a site listing a bunch of Linux training centers.

ZClasses problem
by Alex Rice 29 Jun '99

29 Jun '99

Has anyone been able to create ZClasses via an external method? Can you send me a snippet of code? Thanks, what I'm trying to do is below. Alex *Note there was a typo below. I said Etext/ where I meant Etexts/ ------- Start of forwarded message ------- Date: Sun, 27 Jun 1999 18:06:25 -0600 (MDT) Message-Id: <199906280006.SAA27366(a)inago.swcp.com> From: Alex Rice <alrice(a)swcp.com> To: zope(a)zope.org Subject: [Zope] ZClasses problem X-Mailman-Version: 1.0b8 Precedence: bulk List-Id: Users of the Z Object Publishing Environment <zope.zope.org> X-BeenThere: zope(a)zope.org I'm trying to create some ZClasses via an external method, but I'm running into a problem: I can't getattr() the product's methods. For instance, I have a Product called Etexts, containing a zclass etext a dtml method etext_add (etext constructor) a dtml method etext_addForm (etext constructor input form) a factory etext_factory (etext factory) I can go anywhere in my Zope heirarchy, and in an external method, I can getattr() to manage_addProduct/Etext, but when I try to getattr() to manage_addProduct/Etext/etext, etext_add, or etext_addForm, I get an AttributeError. I don't have this problem within Zope-- for instance in my browser I can successfully call and create a ZClass with http://some_long_path/manage_addProduct/Etexts/etext?id=spam What am I doing wrong to not be able to get to the same method via an external method? Is this the correct way to programatically add ZClasses? As usual, I'm kind of emulating what goes on in the Zope user-interface.
