HappySession

I'm making a site with frames with session management. I'm using HappySession to do it... I need to call SESSION['something'] in various frames at the same time, but when a SESSION expire I got a Transaction Error that blow up my Zserver... Anyone know how to solve this or another SESSION product that doesnt have that problem? Thanks in advance.... -- --------------------------- Diego Rodrigo Neufert -webmaster --------------------------- (Magic Web Design) (email) (diego(a)magicwebdesign.com.br) (curitiba) (pr)

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

Re: [Zope] problem on newly installed Zope2.2.0: I have lost a folder

Such classes cannot be loaded, because the unpickler does not find the source file (it thinks, the class comes from module "__main__", which is not true). Dieter

Success in installing ZPoPyDA (after 3 months...)
by Hung Jung Lu 31 Aug '00

31 Aug '00

Good news. I finally succeeded in installing ZPoPyDA (PostgreSQL database adapter for Zope.) I think it was more than 3 months ago when I started to try to install ZPoPyDA. The process involved many tricky steps, the most tricky one was, uh, installing a whole new Linux operating system. (Upgrade from 5.2 to 6.2) :) But sweat and blood were involved in many other little tiny things. Including installing PostgreSQL and its dev package RPMs, Python Dev, figuring out what was missing in os.h and where to find linux.h for the PostgreSQL, version compatibility problems between PoPy and ZPoPyDA, etc. So many steps that I don't remember them all, now. Do I recommend PostgreSQL to other Zope users? Probably yes. But I'd advise them to give themselves *plenty* of time to deal with installation issues. I know, some have been lucky and did not have any problems. But for me, it's been a horrible experience. But I hope the reward of a good (and cheap) database will compensate all the bad times. regards, Hung Jung _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

I am lacking essential information to understand your setup: * at one place, you say that "standard_html_header" is in a ZClass * at another place, you say, it is placed in a folder. Thus, what is the (exact) relationship between the ZClass (more precisely, the respective ZInstance), the folder and the "standard_html_header". Furthermore, to understand "PARENT", you must consider the URL that let to your object. If this URL went through the folder immediately before hitting "standard_html_header" (or probably another object that uses "standard_html_header") then PARENT[0] is *this* folder and therefore, anything defined by it takes preceedance over things that come from the ZClass.

Re: [Zope] "Z2 CONFLICT Competing writes" and synchronization woes

Sean McGrath writes: > I want to synchronize ... > > I tried using the threading module and creating > a Lock object as a global in the external method. > This does not help as each request gets allocated its > own Lock object.... As you observed, each thread gets its own global namespace for a file containing an external method. The namespace of a true Python module, however, is shared by all threads. Therefore, it is a good place for your lock. Do the following (or something along similar lines): * create a properly named subpackage in "lib/python/Shared" (to avoid name clashes), say "myCompany". * create a Python module in "myCompany", say "myLock.py". * create your lock in this module, say "Lock" * access it in your external method by: from Shared.myCompany.myLock import Lock Dieter

On zope-dev, it was discussed how this restriction can be removed in the future in a controlled way (you do not want to make everything overwritable). To avoid the problem, you can add in your class method something like: <dtml-if index_html_specialized> <dmtl-var index_html_specialized> <dtml-else> .... </dtml-if> and define "index_html_specialized" in your instance, whenever you would like to have specialized behaviour.

Hi Chris and All, No, you asked the right question, scuse me for the error !! I would like only one entry in the form to search in all indexed fields. I like this solution cause it is sometimes difficult for a no regulmar user in this aera (Protein Data Bank) to question the right field. In fact I would like create a simple form ;) FR >>> zope-admin(a)zope.org%internet 31/08/00 12:38:15 >>> Organization: New Information Paradigms X-Accept-Language: en Errors-To: zope-admin(a)zope.org 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 Francois-Regis CHALAOUX wrote: > > Hi All, > > Is it possible to search in all the indexed fields of a ZCatalog with only > **one** input form ?
