Common Folders and Security
by Stuart Nicholson 02 Oct '01

02 Oct '01

I have common set of resources I want individual clients to access but I also want the clients to supply their own secure contexts. However being something of a Zope newbie I'm a little hazy on how I should implement the security in Zope. I have a folder structure as follows: - Common Common resources (dtml method, images etc. etc.) - Clients - AndyInc - acl_user Folder (Users from AndyInc) - BobCorp - acl_user Folder (Users from BobCorp) I can set 'Authorised' security on the AndyInc and BobCorp folders and then do things like: http://zope/Common/AndyInc/CommonResource and Zope will ask Andy to authorise himself before performing publishing CommonResource in the AndyInc context. http://zope/Common/BobCorp/CommonResource has the same effect only now Bob has to authorise himself. QUESTION: But how do I specify security settings (Roles? Proxy Roles??) so that I can stop users from doing things like: http://zope/Common/AndyInc/BobCorp/CommonResource Where because of the naïve security settings I'm using, Zope will ask Andy to authenticate himself and having done so will grant access to CommonResource but in the BobCorp context. Which is NOT what I want. Do I need to create a new Role for each client folder and then grant that Role to the users authorised by the client folder? Is there a better way?

RE: [Zope] interfaces and help system
by sean.upton＠uniontrib.com 02 Oct '01

02 Oct '01

Slightly off topic, I do have an interfaces gripe... or question, perhaps... If interfaces are to be used for API documentation, one thing they lack in the scarecrow interfaces implementation is the ability to declare constants in the interface like you would in IDL or Java. DOM node type numbers are a good example of what comes to my mind in this case. Any thoughts on how you would document objects that fulfill this sort of interface with scarecrow interfaces?

Yes there is, though it is an experimental feature which isn't currently being used anywhere in Zope. If you register an API help topic Zope will not only recognize classes but interfaces in the .py file. You don't have to do anything special just use context.registerHelp() in your product's initialization function. The relevant code is in HelpSys/APIHelpTopic.py BTW, in the future, I think all API docs should be done with interfaces. I have a proposal in the fishbowl for this. http://dev.zope.org/Wikis/DevSite/Projects/APIDocs/ Sadly this project is currently on hold. The reason is that we don't have enough time to work on it. I'd still like to see this project revived, once we have resources available to work on it. -Amos -- Amos Latteier amos(a)zope.com Zope Corporation http://www.zope.com/ _______________________________________________ Zope maillist - Zope(a)zope.org http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

A few questions from a newbie
by azbok＠yahoo.com 02 Oct '01

02 Oct '01

I would just like to say hi all to the zope community. I was previously using Mason (which I still like) and found zope and it looks *GREAT*! I'm quite the newbie though and have a few questions (I have been reading the online books for like a week now and still confused) I did see some previous messages in this group, but the answers didn't help me :( I have zope (2.3.3-1) and a few other modules. I'm using the older version because I'm using debian using apt-get, thats the version that's available. 1) How long would you say it takes to really become proficient with zope? 2) Is it possible to create a variable using DTML and then access it? If so, what would the syntax be? 3) I read about Zope Page Templates (ZPL). Should I just go with that and not bother with DTML? 4) My main question. I have a Z SQL method which takes a parameter. It works using the Test tab. I get it to work thru DTML too. How do I properly pass a parameter to it using Python? I try something like: context['MyZSQLMethod'](MyParam=1) It might be right for all I know, but even if it is I dunno what to do with it. How would I loop thru the data it returns? Thanks greatly for any feedback from you mighty gurus out there :) Azbok

Use properties of a product?
by Lars Heber 02 Oct '01

02 Oct '01

OK, I have a product, lets say AA. It has a property location. Within this product, I have a ZClass. In the addForm, I'd like to pass a standard value, which is the "location" property of AA, to the user within the form. He can change that value, and that value becomes a property of the ZClass, let's say "actualLocation". I could not find a possibility to access the location prop of AA. <td><input type=text name=actualLocation size=60 value="<dtml-var location>"></td> does not work. Any suggestions? Thanks! -- Lars Heber, mailto:Lars.Heber@t-systems.de T-Systems, debis Systemhaus GEI GmbH, Geschaeftsstelle Sachsen

Hello, Can somebody give me some clues on how to solve the PicklingError that Zope is raising to me from time to time ? It seems that Zope cannot always commit its transaction when I am adding a new object to an object manager. Thanks in advance, Philippe

Unstable Zope: Out of Memory problems
by Paulo Eduardo Neves 02 Oct '01

02 Oct '01

Two weeks ago I started to have stability problems with Zope. I'm getting a lot of random "Out of Memory" errors. I'm using Zope in this server for more than an year, I don't know what's happening now. Sure I wouldn't won an oldest running Zope context before, but now it's restarting each 20min! Zope server starts fine with some 14M and crashes when approaches 20M. I'm trying to minimize the amount of memory that Zope uses. I did: 1. put a lower amount of cache in the Control Panel > Database Management > Cache Parameters tab 2. removed full sections of my site, now my Data.fs has just 10M 3. lowered the number of threads, it's running with the default four. Is there anything more I can to run Zope with less memory? I've also tried to debug it, using the debug tab, but everything looks fine. The top object has less than 450 refcounts. Can anyone help me to debug it? Maybe the problem is with my server, I'm with Zope Server behind Apache (with mod_gzip) via mod_proxy in a FreeBSD 4. It's a virtual private server of ViaVerio (know before as IServer). The support said they allocate me just 14M of memory for each process. It worked fine for more than a year. I've found an old zopista that uses the same server and also had out of memory errors: http://lists.zope.org/pipermail/zope-cmf/2001-April/006458.html Would my only solution be to change my hosting company? Do other zopistas have any suggestion of hosting plans that give "almost root" power for less than US$100? Besides IServer, I've just found this one from ForSite: http://www.forsite.com/vds.htm It is a little off-topic, please answer me privately about the servers that I'll post a summary to the list. regards and thanks in advance for any help, Desperate Paulo -- Paulo Eduardo Neves mailto:neves@samba-choro.com.br Agenda do Samba & Choro, a boa música brasileira na Internet http://www.samba-choro.com.br

Sorting of objectValues within python script
by olpa＠sybcom.de 02 Oct '01

Hi, one question again that I could not find neither in the mailing list nor in the ZopeBook: I have a list of ZODB objects, collected by using objectValues. How can I sort this list by the id? is this SortEx? how can I access SortEx? from within python script? --- I think we dream so we don't have to be apart so long.
