Very nice! I think a lot of the pain of dealing with Zope through the current management interface goes away if the latency of the request/reply cycle is imperceptible -- your tree view emulates the interface perfectly, and quickly (of course caching has its own problems...). I wonder if we could fold in the XUL markup editor, and allow client-side creation/editing of DTML documents and methods (with some validation?), with submission. -- ========================================================= Tres Seaver tseaver(a)palladion.com 713-523-6582 Palladion Software http://www.palladion.com

XML_RPC client for internet explorer
by Johan Carlsson 09 Jan '00

I've "compiled" an XMLRPC client (from David Carter-Tod's XML-RPC Client and Server for ASP) that seems to be working with Zope, but it has not been tested (patches and bug rapports are welcome). http://www.zope.org/Members/johanc/ZIE/xmlrpc_client David Carter-Tod's XML-RPC Client and Server for ASP (the client has a bug for working with Zope, simply add [objXML.setRequestHeader "content-type", "text/xml"] before the [objXML.send(requestText)] in [xmlRPC] you be alright.) http://www.wc.cc.va.us/dtod/XMLRPC/ Regards, Johan Carlsson

If you are using a browser that is running on the same machine as Zope and you are using RedHat 5.1 or 5.2. This problem doesn't occour for us when running both the browser and the server on RedHat 6+. We consider this then to be a pretty minor bug.

I am very slowing working on a Zope Developer's Guide. This will be a large Guide that covers things like building Python Products, ZClasses, ZPublisher, etc. Unfortunately this is a very large project and my time is very limited. We also have plans for eventually getting authoritative API documentation in place. However, this effort is not very mature yet. My hope is that we can soon move to a situation in which Guides are available through CVS and folks who are interested can participate directly in writing and editing them.

I think that this is a great idea. The main problem with it is that it is a lot of work to review someone's product. I think it would take me a couple hours to go through someone's code and try to figure out how it works and how it could be improved.

Can you comment on this > Amos? As I stated above, we need to finish and make available more Zope Product tutorial information. I don't think that we need an official good-Product description. That said, here's a quick list of what I think a good product should do: * correctly subclass existing Zope classes * correctly handle permissions * correctly handle persistence * present a reasonable HTML UI to users * present a reasonable API to DTML programmers * include some documentation A good product mostly is one that works correctly ;-) Of course there are gray areas, like what is a reasonable HTML UI? And how should you decide what methods should be protected by what permissions? For questions like these I agree that we should come up with some recommended practices. As for getting this done I see this general procedure: 1. identifying areas that need recommendations 2. proposing recommendations 3. reviewing recommendations 4. blessing recommendations I think much of this work can be accomplished on the Zope-dev list with Zope community members and DC folks working together. (I think of these as Zope community recommended practices, not DC recommended practices.) I personally would be most interested in working on step 3. BTW, when recommendations get to the blessing stage we may want to revise Zope itself to follow the recommendation. -Amos -- Amos Latteier mailto:amos@digicool.com Digital Creations http://www.digicool.com

How do index the contents of a File?
by Carlos Henrique Bauer 07 Jan '00

07 Jan '00

Hi, I created a ZCatalog to index all the contents of a site. To index the contents of the documents I added a 'raw' text index to the catalog, but it seems to be working just with DTML Documents. Do I need to add another index to the catalog to make it index File documents or is it a ZCatalog bug? Best regards, -- Carlos Henrique Bauer

Permissions interface improvement request
by R. David Murray 07 Jan '00

07 Jan '00

Perhaps this has been brought up before, and perhaps there is some other place I should submit it (if so, let me know). Also of course let me know if there is some way to do this and I'm just not seeing it. In working with the security screens in zope I have one major problem with the interface. I have a site, and at the top level I define some new roles and give them some global permissions. Then I have a subfolder. Now, in this subfolder I do *not* want anonymous view access, etc. As far as I can see, the only way to remove anonymous view access is to remove the 'inherit permissions' from those permissions that anonymous has, and then to give them back to those roles that ought to have them. This seems like a lot of work with some potential for mistakes on later updates, when all I really want is a checkbox that says, 'anonymous has no permissions in this folder'. So assuming I'm not overlooking something, I guess my enhancement request is that there be an 'inherit permissions' checkbox for each role as well as for each permission. --RDM

Sorry, but my web > experience expects > that. (This is probably more along the lines of a general zope list question (zope(a)zope.org)) An understandable thing. To me, a filesystem is just another type of data store, just like the Zope database or a relational database. And there's no saying a URL can't at some point be translated *into* a file, its just no one really does it much. I believe a couple different people have come up with products that let you 'mount' a filesystem from Zope. Not so much that there is a reason why there *aren't* filename in Zope URLs, there is a reason why they *are* in other solutions. Zope is a framework, all of it's components exist in an object space that allows them to work together at a fundamental and application like level. > 1.

RE: [Zope-dev] ASP vs Zope vs PHP vs ..?
by Andy Pahne 07 Jan '00

To say it first: I have no experiencce with ASP, but I'm developing a few websites with Zope and a few with PHP at the moment. Zope is very appealing, you are right. But I do not understand your mention above: >But, I'm uncomfortable with loosing touch with an actual HTML/ASP document >in an actual file system. I feel weird about the URL that Zope presents - >there's no simple file name reference, like, http://www.abc.com/mypage.asp >or http://www.abc.com/mypage2.html. Sorry, but my web experience expects >that. In fact, Zope maps objects to URLs, and you access your Zopish objects via URL. So the reference to the object myObj in the root-folder of your Zope-installation gets http://your-server.com/myObj If you like it, you may call your object myObj.asp or myObj.php or even myObj.html. .That's a simple name reference, isn't it? OK, in fact there's more to tell about it, but the strength of aqcusition is one of the more easier concept, and I won't go into detail about that now. We had this thread Zope vs PHP and Zope vs Midgard-Project and Zope vs ASP already, and I decided to use the best out of all worlds. At the moment I'm trying to learn, which technique is the best for a given problem. Andy

Soft-links in a filesystem don't bump the link count on the target, so the link can be stale: this may be mitigated by the fact that a developer is likely to split the ZODB along "coupling and cohesion" lines, so the number of cross-ZODB links is likely to be small. > > - How do databases get connected, from a UI point of view. > Do you get to specify a database when you add an object? > Any object?
