Am I really expected to understand this "Therefore"? In fact, I do not! Does it mean, that a Superuser can execute any method with *ITS* privileges and not the intersection of its priviledges with the owners privileges? I hope (and expect) not! Why is it much worse when an object is owned by Superuser than by a manager? What are the differences with respect to the Trojan Horse or other security issues? Dieter

Call for Python Method opinions
by Evan Simpson 07 Sep '00

07 Sep '00

If you want any say in how official Zope Python Methods work, I recommend heading over to: http://dev.zope.org/Wikis/DevSite/Projects/PythonMethods/StandardPythonMetho dModule ...soonest. If you have feedback on any part of the project, please contribute, but the link above is the squishiest part of the design, and possibly the most important to many of you. User-style documentation is still scanty, but getting better. Comments on where it needs to be stronger are welcome. Cheers, Evan @ digicool & 4-am

Re: [Zope] How to access id and title of document calling standard_html_header

It should be impossible to get the id of the *standard_html_header*, if this header is a DTML *method* (rather than document) as you told us in a different message. Because we see different things, we need to describe carefully, what we do. Apparently, we do not do the same. I have a folder-like ZClass, say ZC, and an instance of this class, say ZI. ZC has a method, say M, using "standard_html_header". "standard_html_header" is a DMTL method (!) rendering "id". When I open "ZI/M", "standard_html_header" renders "ZI", i.e. ZI's id. The same happens, if "standard_html_header" is not in ZI but a ZC method. Now, it is your turn to describe precisely, what you are doing. Dieter

Re: [Zope] Java applet with inner classes causing probs in Zope
by Eric L. Walstad 07 Sep '00

Just a follow-up: Morten Said: // Adding files to Zope through FTP doesn't seem to have the same restrictions. Actually, it did for me. FTP was able to upload all the class files except those with the $ in them (the classes with inner-classes). That's how I found out about the problem. Holger Lehmann said: // What about putting it all in a jar-file ? I tried that, too, but Java would choke on running the Jar file that was served from Zope. If anyone has a working JAR file applet in Zope, I'd love to see the syntax they used! To make my applet work, I had to go into the java code and separate out the inner classes so that every class was in its own file. This turned out to be a lot easier than I expected. Eric. Here's the original message... > Hello all, > > The problem is that inner classes have names like "Parent$Inner.class" > I'm unable to create a Zope file object with a name that includes the dollar > sign.

ANN: Serving PHP/Perl from Zope update
by andres＠corrada.com 07 Sep '00

07 Sep '00

Hello Zopistas, I have updated the HOW-TO: Serve PHP/Perl within Zope with a nifty alternative by Joseph Wayne Norton. His suggestion allows PHP to call Zope methods. Check it out at www.zope.org/Members/Mamey/PHP. The methods presented in the HOW-TO still have some deficiencies with regards to Authorization and Cookies so suggestions and improvements are very much welcome. ------------------------------------------------------ Andres Corrada-Emmanuel Email: andres(a)corrada.com ------------------------------------------------------

RE: [Zope] ZClass base classes
by Chris McDonough 07 Sep '00

07 Sep '00

Hi Nick (please don't post HTML mail to the list). I *think* the "Include standard Zope persistent object base classes" check box gives your ZClass the "ZObject" interface which is similar to the SimpleItem interface (see the Zope API docs in the help system - I think it's under Help->Zope Help->API Documentation->ObjectManagerItem). As far as inheritance order, the first base class you add to the ZClass base class list will be ZObject if you use check the "standard base classes" checkbox. The next one will be the first base class you choose (the topmost), the next one will be the one under that, etc. -----Original Message----- From: Nick Trout [mailto:nick@videosystem.co.uk] Sent: Thursday, September 07, 2000 8:59 AM To: Zope Mail list Subject: [Zope] ZClass base classes I've looked all throught docs but I cant find anywhere an explanation of what properties the ZClass base classes give you. Also which order to inherit them, as the Developers Guide claims the order is important. Can anyone please enlighten me? Regards, Nick.

[New User]: Investigating Zope...some preliminary questions
by Vaibhav Goel 07 Sep '00

07 Sep '00

Hi all: I am currently investigating Zope as a possible "tool" to use for building the back end "engine" for several projects for our company. Some of the sites we are currently doing involve E-commerce, news, etc. It is definitely a very powerful system and I think I have not even scratched the surface. I tried the QuickStart (ZAcme) tutorial and got a feel for whats involved. A few questions came to my mind and maybe I am not getting the "right picture" so to say but I would very much appreciate if someone could take the time to answer these: 1. If we were to go ahead and start using Zope as a "back-end engine" to build websites, basically a team of 3-4 people would be involved. Do they have to have knowledge of Zope? For example, I am the back-end guy....creating, programming the middle tier code for database access and what not. The guy who does the front-end (ie html code, layout ) and graphics guys are not very technical. How will I go about "importing" the front end code within Zope? Are there any modules for DreamWeaver etc (Windows based tools) that integrate with Zope? 2. What about stuff like importing legacy websites? For example, our main website is built using ASP running IIS. I was planning to recode it all in PHP + MySQL. Are there any "straight forward" ways to migrate legacy stuff easily? Again, please accept my apologies if this stuff is covered in the documentation somewhere. So far, I have gone through the Zope Content Manager guide and did not see any details about these questions there. I am in the process of browsing through the mailing list archives and I am sure I will find a lot of info there. Any tips and suggestions are highly appreciated.
