ZPatterns is very cool, but still not documented. It's alpha but seems stable enough for production in a lot of cases. Phil? Steve A? backup? ;-) cheers, Chris

Argh, I take back what I said. As long as your SESSION objects have different cookie names, it should be OK to have multiple SESSION objects. They will operate independently. It's OK to have multiple SESSION objects. (They expire independently, too.) regards, Hung Jung _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

RE: [Zope] manage

Hi dieter, Thx for ur reply. The child window pop ups when u do http://localhost:8080/manage . One enters the username and password there. That is validated against the acl_user folders member names or if it is a superuser who installed zope it validates it against the access file. I want to look at the source code and understand the authentication mechanism.That's why i want to know the following:- 1.what is the python file which pops up that child window for entering username and password ? 2.After u give the username and password what is the file / module name against which the username and password is authenticated. 3.what is this 'manage'....? method/module???

That is exactly what one would expect. Enter the username and password that was assigned during installation or that you set with python zpasswd.py access > Is there a way of running zope with debugger?? There is "Test.py" in "lib/python/ZPublisher". It will, however, not help you with the above problem. Dieter

You can see the error if you try to access the broken product definition in the control panel.

Re: [Zope] Success in installing ZPoPyDA (after 3 months...)

>From: "Bak @ kedai" <kedai(a)kedai.com.my> >where did you find linux.h that's needed by PoPy? thtt stump me from >continuing. Download postgresql-7.0.2 source (not the RedHat's RPM), unzip and untar it, and the file is located at: postgresql-7.0.2/src/include/port/linux.h What I did was: (1) copy this file into your /usr/include/pgsql (2) delete /usr/include/pgsql/os.h (which is merely a link, not an actual file) (3) rename /usr/include/pgsql/linux.h to /usr/include/pgsql/os.h Oh, I also had to tweak some of the Makefiles at some point, so the include directory becomes pgsql instead of postgresql. regards, Hung Jung _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

>From: Diego Rodrigo Neufert <diego(a)magicwebdesign.com.br> >... >too... well, in the standard html header I call call a method that do a >call in >all my sessions.... Okie, now I see why you get the Transaction error problem. After an exception is raised, Zope aborts the http request transaction, and any attempt to further use Zope objects that are transaction-aware will cause an error. In the next release of HappySession I will try to detect whether the transaction has ended, and return some meaningless result like None. But the real thing is, after the exception happens, SESSION object should not be called again. If you really need to call SESSION in your standard_html_header, then please do two things: (1) Please use a standard_error_message, and it should start with something like: <dtml-if "not error_message and error_type == 'SessionNotFoundError'"> <dtml-return session_not_found_html> </dtml-if>     .... (2) In your session_not_found_html, please do NOT use <dtml-var standard_html_header>. Instead, write another DTML and call it session_ended_html_header, and use it instead. Inside your session_ended_html_header, please do NOT call the SESSION object. >I have two SESSION objects, one in the root of zope and >other in the opt folder of zope.... look how I call the SESSIONS.... >in standard_html_header ><dtml-call callSession> > >The callSession method: ><dtml-call SESSION> ><dtml-call opt.SESSION> (Hmmm... multiple SESSION objects... in typical situations usually one single SESSION object should be enough. Notice that two SESSION objects mean two separate storage. Although HappySession is designed to handle multiple SESSION objects sharing the same key cookie, the expiration time might be a tricky issue... I do not recommend multiple SESSION objects.) The thing I don't understand is why you need to make explicit call to the SESSION objects. Ohh...! I see, you probably think that SESSION objects need to be initialized? OK, unlike FSSession or SQLSession, HappySession's SESSION objects do NOT need to be initialized! You don't need to make an explicit call to SESSION in your standard_html_header. HappySession is smart enough to initialize itself whenever you touch it the first time using any of its methods. No explicit initialization call needed. (I'll add an observation on this in the help file in the future.) --------------------- In short, I think that by simply removing your callSession method and its reference in standard_html_header, you will be fine and happy! :) regards, Hung Jung _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

Announce: Squishdot 0.7.0 now available!
by Chris Withers 01 Sep '00

01 Sep '00

Squishdot 0.7.0 is now available from http://www.zope.org/Members/chrisw/Squishdot/ http://www.squishdot.org/Download/Squishdot The following changes were made: - Changes to the Demo Sites and Squishdot core to make them Zope 2.2 compatible. - Updated Cataloging to use the Traversal Interface. This means 0.7.0 will not work with versions of Zope earlier than 2.2.0! - Added in some html_quoting. The Demo Sites could do with a lot more. - Some small changes to the management screens. I'm not 100% happy about how the 2.2 support was achieved, so expect a 0.7.1 release in the near future. If you run into problems, remember Squishdot has a mailing list at eGroups and a bug collector on SourceForge. cheers, Chris

All i will say is that it is a very high profile list for professional web artists. Mainly Silicon Alley types If that describes you, you should know what list i mean. Others have asked "what to you mean by enterprise?" I'll rephrase that part of the question. "What large US corporations are creating mission-critical e-business applications (and of what type -- send URLs if you can) with zope?" As for traffic figures, someone in my office (you know who) claims that zope can easily handle 1million hits per day running on crappy hardware. Hardware aside, where are the Zope sites that generate this kind of traffic? Certainly not toyota-motosports.com.... Thanks for your participation.
