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? Zope Version: Zope 2.3.1 (binary release, python 1.5.2, linux2-x86) Python Version: 1.5.2 (#10, Dec 6 1999, 12:16:27) [GCC 2.7.2.3] System Platform: linux2 Andres Punning

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')">

I followed an sample from "Chapter 12: Extending Zope" of Zope Book however the following pythonscripts didn't work. ================================================== ## Script (Python) "isHungry" ## """ Returns true if the animal hasn't eaten in over 8 hours """ from DateTime import DateTime if (DateTime().timeTime() - self.last_meal_time.timeTime() > 60 * 60 * 8): return 1 else: return 0 ================================================== The problem: "self" not found! I've tried "container", "context" and other possible mixes and still don't have any clue to get it work. Please help. Thank you. Roger.

Users editing properties -- howto?
by Leigh Ann Hildebrand 17 May '01

17 May '01

Some background: I'm using Zope to create and manage an internal document library for engineers and developers. Because of the circumstances, website security isn't an issue; I don't have to require logins for users. I work in dtml only right now -- no python. I have only been doing so for a couple of weeks. I'm not a programmer. (Translation: use small words and don't assume I know how to do basic things yet!) I've been asked to implement a keyword indexing/search feature. Documents are currently represented by dtml documents, with a "keywords" property of the type "tokens". I'm listing the keywords at the top of documents, by referencing <dtml-var keywords>. I'd like for users to be able to use an "Add" feature to add a keyword to a document if they feel one is missing. That would involve an "Add keyword?" link, I guess. The result would be that the keyword property for that document would be modified. Can anyone offer suggestions/examples for doing this? Are there problems with it? (Other than the problems with keyword indexing in general, please.) Is there some more elegant way to handle this, that I, as a non-python person Zope newbie, could handle? Thanks!
