Re: longest running zope

Our bug-tracking system (Zope + PostgreSQL + Linux) uptimes are limited by mains power -- I can't seem to get beyond 100 days. Current uptime for both the server and Zope is 29 days. Except for power problems the system has not misoperated in any way I have seen (and people would let me know) in the two years we have been using it. As far as I know it will run forever. Well, actually I think that there may be some PostgreSQL index files that may keep growing. -- cary

FSPoll question #2
by Joe Copeland 17 May '01

17 May '01

I was wondering how you would structure the DTML code to create a FSPoll exactly like the one on the zopezen.org site. The HTML code shows this poll is in a little table. I'm having a tough time figuring out how to call the poll using DTML. I'm just learning so please forgive my ignorance. I tried a bunch of combinations of the dtml-var tag and the dtml-with tag. I think what stumbling me is the URL format. You have to call up the question and then vote_small_html to display it in HTML. The URL is like ..question/vote_small_html. -- Joe

FSPoll
by Joe Copeland 17 May '01

17 May '01

I think the FSPoll product is a neat idea but I can't find any documentation on how to use it properly. I installed in on my system with a little moving of the files since the tar build is kind of messed up. Anyway, I'm just trying to figure out What the relationship of the FS Poll folder is supposed to be in relationship with the questions and the answers. -- Joe

Security problem
by Punn 17 May '01

17 May '01

Hello, I am newbie. My Zope security works in a strange way: The security tab says as follows: When the Acquire permission settings checkbox is selected then the containing objects's permission settings are used. It took me some time to understand, that the settings are USED, when the Acquire permission settings checkbox is UNchecked. All checked settings are ignored. For example, if I want to prevent Anonymous user seeing something, I must uncheck in the View row "Acquire permission setting" and "Anonymous user" columns. What is wrong?

bug in ZClasses: Folderish ZClass shows wrong "subobjects" meta_types
by Danny William Adair 17 May '01

17 May '01

Hi! For my folderish ZClass I find "subobjects" in the management screen to determine which objects are allowed to be added inside my ObjectManager. The "subobjects" tab shows me a list of meta_types to choose from, so that I can make sure I don't get a "the object xyz doesn' t support this operation" when creating/pasting objects of that metatype. But the list is faulty! :-o :-o 1) Created folderish ZClass "Universe" ,metatype "Hello Universe" 2) Created folderish ZClass "World" ,metatype "World" 3) Added "World" to the allowed subobjects list of "Universe" That's ok. Works as expected. Now let's say I find out that "World" is a bad meta_type (there can be several reasons for this, for example someone else has just released a wonderful product, which instantiates "World" objects) Now... 4) Changed the metatype of ZClass "World" to "Hello World" 5) Damn, *now I can't add any World instances in my Universe instances anymore* :-( So, then Universe's "allowed subobjects" list wasn't adjusted automatically... mmmh, ok. Then I' ll do it manually. 6) Right, go to ZClass "Universe" and look under subobjects to correct the entry... Boing! I only find "World" in the list, although this metatype shouldn' t exist anymore. But I can' t find the new metatype, "Hello World", and so I will never ever again be able to add them in a Universe instance. Can anyone reproduce this misbehavior? Now, how can I fix this once it has happened? I love "Hello World" and I hate "World", so how can I get it back? My first attempt was to rename the ZClasses and add new ones... bang. "The permission Add Hello Worlds is already defined." Ok, break, this will get way to complicated... So then, I would call this a bug in ZClasses, can somebody confirm this? def possible_meta_types(self): return self.aq_acquire('_product_meta_types')+Products.meta_types This is what the management screen calls to show me the wrong list, maybe someone knows what's happening here and how to fix this? tia, Danny P.S.: - Zope 2.3.2 (binary release, python 1.5.2, win32-x86) , Python 1.52 - yes I flushed cache, packed db and restarted zope in between

Hi Jan, for a first shot you might want to look at the vary-tag. http://www.zope.org/Members/tino/ However, to integrate it better into Zope and solve the unicode-issue and so on, there is an effort already.

Poll product
by Chris Muldrow 17 May '01

17 May '01

We had someone pinging our poll with an automated script. We didn't want users to have to log in before voting, but still wanted some way to keep people from hitting the vote method more than once per session. (We're using the poll product mega modified from Amos' Poll Product) We decided to throw a cookie at the users and check it when they go into the poll--on first visit it lets them vote, but then it cookies them and redirects to the results page. This is pretty straightforward for Zope addicts, but I figured this might be useful information for someone, so here goes: Just paste the following chunk of code at the top of the index.dtml file that sits in the poll product: <dtml-if "REQUEST.has_key('voted_in_poll')"> <HTML> <HEAD> <META HTTP-EQUIV="Refresh" CONTENT="0;URL=<dtml-var absolute_url>/results"> </HEAD> </HTML> </dtml-if> <dtml-call "RESPONSE.setCookie('voted_in_poll', '1')">
