Variable sort, size in dtml-in
by Brian Sullivan 19 Aug '02

19 Aug '02

I have been exploring using dtml-in to display selected items from a catalog. I would like to (from the page that is doing the displaying) be able to: 1) let the user change the sort order by using some sort of selection on the columns 2) let the user modify the "size" attribute 3) continue to retain the original "sequence-query" variable 4) have all displays ongoing reflect both the size, sorting changes and original "sequence-query" Does anybody have a dtml sample ( or a place to look) that does that or can give me a clue as to what strategy to use?

I guess it's enough to let them know what advantages and disadvantages each browser has and not forcing them to choose one browser. After all, everybody is free of doing what he wants.

RE: [Zope] SQL: nested select
by Schmidt, Allen J. 19 Aug '02

Depends on the DB, also. As far as I know, MySQL does not allow sub-selects like this. If I need something like this, I first create the query to handle the sub-select and then include in the place with a dtml-var.

I'll take a stab at some of them...

What changes will be done to the PropertyManager? It will be entirely rewritten. One thing to realized with Zope3 is that you will likely have several implementations of basic functionality like this to choose form. One implementation might store the properties in the object another might use an external database or a surrogate object. Each would have the same interface so the application code would be the same regardless. > 4. Will the class Folder store the content in BTree's? (BTreeFolder2) As implemented now, yes. It may be further refactored to take a hybrid approach (dictionary for small folders, BTree for large ones). > 5. Which changes will be done to ZCatalog? It is being rewritten from scratch as "ObjectHub" which handles base services related to creating "tables" of objects. Indexing and query support will be an ObjectHub add-on. > 6. Will the UserManagement be changed so that a role can include another role? No, roles cannot be nested. However Zope3 will include the notion of "Principal Groups" similar to user groups in other systems. These will be able to be nested and directly granted either roles or permissions. Principal is the moral equivilant of a Zope2 user, but it also captures other actors who are authorized in the system (like groups, certificates, the system, etc). > 7. What changes will be done to the Permissions? Permissions will be able to be explicitly denied as well as granted. Permissions will be able to be categorized to simplify their management. > 8. How useable is Zope3? Most of the framework is there, but there is much work to be done on the user interface (ZopeTop). > 9. How can I store Properties which should be common to all instances > of a class? Class attributes would be one way (like today) Another way could be using a utility (a application global object) stores global property values. There are other application level inheritence proposals and ideas floating around, such as TTW modules and object templating ideas. My guess is there will be many ways to do it. -Casey _______________________________________________ Zope3-dev mailing list Zope3-dev(a)zope.org http://lists.zope.org/mailman/listinfo/zope3-dev -------------------------------------------------------

The Zope Bible is one of those 'lots of screen shots" little content book although there are folk who recommmended it. The ZWADACM book has lots of useful information but it's an overview at a system level not about the guts. The Books of Zope it an intro tutorial, cluttered with some screen shots, but with examples... Dieter Maurer's three chapters are more useful than the lot. Download them from www.handshake.de. They explain the ideas and principles rather than glossing over the hard parts ... There, that's a bit more comprehensible.. 1

Zope3 Questions
by Thomas Guettler 19 Aug '02

19 Aug '02

Hi! Here some questions about Zope3: I asked them on the wiki[1] but noone replied 1. What version of ZODB does Zope3X use? 2. Which Python version will be recuired? 3. What changes will be done to the PropertyManager? 4. Will the class Folder store the content in BTree's? (BTreeFolder2) 5. Which changes will be done to ZCatalog? 6. Will the UserManagement be changed so that a role can include another role? 7. What changes will be done to the Permissions? 8. How useable is Zope3? 9. How can I store Properties which should be common to all instances of a class? Yes, there are special Zope3 mailinglist, but I am only subscribed to this one, and I think many others are interested in it, too thomas [1]: http://dev.zope.org/Wikis/DevSite/Projects/ComponentArchitecture/FAQ

If you must use Windows, get Cygwin. Linux is a more developer-friendly environment even if you are just starting out.

Many thanks to all and sorry for delay, we leave homes and our army saves our souls :) We are today in back and have here "big water", 100m from me is absolutely new, 60km^2 sized ocean with brown water. Pound seems to be fantastic. But how to make virtual domains (name-based webs) with pound? Or it is only feature of apache (as in www.zope.org\Members\mwr\VHosts_With_Zope_Default)? Many thanks J Lukesh

session data containers, browser_id managers, etc

Is there any problem with having multiple instances? Or should it all be limited to a single instance at the root?
