Hi, Is there any support for DB2 on Zope? I've found some comments on the web, but not really much... Thanks, Stephan

RE: [Zope] Setting Local Roles from Python
by Keith Alperin 29 Nov '01

29 Nov '01

This is exactly what I needed! There are two things I would like to clarify for other Newbies: 1)the method that is provided below is taken from the source. Thus, in order to call the method you need to omit the 'self' argument: manage_setLocalRoles(userid, roles, REQUEST=none) 2) The 'roles' argument is a list, so passing in a string is read as a list of characters. Thus, the method call might look like this: manage_setLocalRoles('myid', ('Manager',), REQUEST=none) Thanks so much Chris for your help! Best, Keith R. Alperin -----Original Message----- From: Chris Price [mailto:cprice@orbik.com] Sent: Tuesday, November 27, 2001 5:18 PM To: Keith Alperin Cc: zope(a)zope.org Subject: Re: [Zope] Setting Local Roles from Python you can do this type of thing via the method manage_setLocalRoles(self, userid, roles, REQUEST=none) you can check out the source in lib/python/AccessControl/Role.py but basically, if 'Manager' is in the roles list that you pass to the function, the user will have Manager access to that object. one catch is that whatever object that you have call 'manage_setLocalRoles' will need to have the correct permission to call it. I think it is the 'Manage Users' or 'Change Permissions' permission. This should only be an issue if you are trying to add the role programatically as opposed to manually. You can also set up a 'proxy role' on the object that is going to be calling manage_setLocalRoles--that way the user doesn't necessarily have to have 'Manager' role in order to invoke your call to 'manage_setLocalRoles'. I have created a product called 'ZLocalRolesManager' that I am thinking about cleaning up and releasing on zope.org. Its purpose is to provide an easy way for you to allow users to assign local roles on objects. The way it works is, you create an instance of it, and set a property called allowed_roles. allowed_roles has type 'lines' and contains a list of roles that you want it to allow the user to dole out. then you can set up a view in a zclass, or just set up a DTML method that calls the LocalRolesManager, and your users will have the ability to assign local roles. They will only be able to assign the specified roles, so you can prevent them from handing out 'Manager' roles, etc., if you choose. it's a very simple product but it has been very useful to me... if anyone is interested in it shoot me an e-mail, and that will encourage me to clean it up and post it on zope.org. :) chris On Tue, 2001-11-27 at 17:03, Keith Alperin wrote: > Greetings!

ObjectManager FTPlist - acquisition issues
by Chris Price 28 Nov '01

28 Nov '01

I don't know if this the right place to ask these questions... I somewhat think that this belongs more in the zope-dev list but I'm hesitant to post there since I'm not officially a developer of Zope. There is a problem in the manage_FTPlist method of ObjectManager. I found a patch (written by Deiter Maurer and available at: http://www.dieter.handshake.de/pyprojects/zope/#bct_sec_5 ) that might fix this issue, but I'm uncertain as to the status of this patch. I'm not expecting anyone to solve this for me right away, but I would like to know what the right forum is to discuss this, who is the maintainer of this code, how to monitor the status of it, etc. I would also like to know what the status of Deiter's patch is; is it scheduled for inclusion in a future release of zope? Is it a potential security hole? If there is some place that I can go to find this information, could someone please let me know where? Here is a more detailed explanation of the problem: There is a bit of code in ObjectManager.py where it checks to see if an object is acquired: ob=self while 1: if App.Common.is_acquired(ob): raise ValueError('FTP List not supported on acquired objects') if not hasattr(ob,'aq_parent'): break ob=ob.aq_parent Now I'm not completely familiar with the inner workings of zope, so I'm not sure I understand how this is supposed to work. What I do know is that a ZClass that is nested inside another ZClass in the Products folder will cause problems with this bit of code. If you FTP into your ZServer and do: cd Control_Panel/Products/SomeProduct/SomeZClass/propertysheets/methods cd NestedZClass/propertysheets cd methods then the "ValueError" above will be raised. The while loop runs 3 times, with 'ob' being set to the following three objects: <ZClassMethodsSheet instance at 8942708> <bar_ZPropertySheetsClass instance at 88e3a58> <ZClass instance at 886c320> The ZClass instance then passes the 'is_acquired' test, the ValueError is raised, and the FTP server says 'No such directory'. So is the acquisition check just overkill? If it is removed, will that solve the problem? Or is the problem actually related to the fact that the <ZClass instance> passes the 'is_acquired' test when it should not? My apologies for getting so deep into this issue on the list here, but I just don't know where else to address my questions to. This problem is crippling FTP access to my development tree, and that is a critical factor in whether or not my company chooses to use Zope or not, so I would really like to get to the root of this problem. thanks for any info you can provide! chris price

import paths
by Scheck, Garth 28 Nov '01

28 Nov '01

I am trying to create an external method in Zope that links to a method in a Python script called "db." The Python script "db" imports another Python script I created called "GDAC". Both Python scripts are located in the Zope site's Extensions directory. When I try to save the changes on the external method I get an import error saying that it cannot find module "GDAC." Should GDAC be located in a different directory? What is the search path for imports within Zope? NOTE: This script works fine in PythonWin. Thanks, Garth

Thats OK, what is not working? I don't use Eudora so I am not sure I can help you, the list is your best bet... -----Original Message----- From: Vid Bijelic [mailto:zoops4@yahoo.com] Sent: 28 November 2001 21:12 To: Norman Khine Subject: RE: zope - webalizer Hi Norman, First thanks on very detailed explanation. I set a cron job and webalizer to include logs only for /vid/website1 I used IgnoreURL * IncludeURL /vid/website1 I try with n domainname.com but it did not worked, so I use webalizer.config file with above setting. It is giving me stats now only for website1, I assume I could get much better results with Virtual Host product, but I have never try using it. By the way, I will post this on the Mailing list too. When Eudora users receive e-mails sent using Zope MailHost product, they got it all wrong. If I send HTML formatted text they got it as a plain text, if I attach PDF file they got it as bunch of gibberish. I try different type of encoding and nothing helped. Every other e-mail client receives it correctly.

i want a timeout interrupt
by Horst Wald 28 Nov '01

28 Nov '01

Hi, can one interrupt the execution of a script when a certain amount of time has passed? What I want to do: - I start with a given URL. - Then I read the webpage denoted by it into a string like page=urllib.urlopen(URL).read() and if it satisfies a given condition (e.g., it contains a certain word), parse it to find out all the urls it contains. - With these new urls I continue - I take care not to read the same URL twice This works fine in general, but there are certain web pages that never respond. If you try view them with a browser you get a timeout after a few mintues. But the urllib.urlopen() script keeps waiting until it gets a response and if never gets one, the whole program is stopped. What I would like now is to interrupt the script an return '' if it gets no response after 10secs. Any idea???

Passing a Variable from PHP
by Ben Ocean 28 Nov '01

28 Nov '01

Hi; I need to pass a variable from a php script (served by Apache) to a Zope script (served by ZServer). I can't do this as a hidden field in a form since there is no *form* on the php script: indeed, the user never notices the script as it doesn't generate any html. This is a randomly generated variable. How do I communicate it? TIA, BenO

Derivation from DTML document
by Tille, Andreas 28 Nov '01

28 Nov '01

Hello, I'm planing to write a new ZClass derived from DTML Document. The initialisation of an instance of this ZClass (MyDocument for instance) should contain the selection of some certain keywords, which would be added in the meta tags of the resulting html output. I just want to make sure that there is no such thing I'm looking for and that I will not reinvent the wheel. Kind regards Andreas.

How to change values in tiny table
by Clark OBrien 28 Nov '01

28 Nov '01

Can anyone tell me how to update the data in a squishdot table after changing the dtml file. I don't care about dynamic update at this point but I just want to see the changes I have made with my editor. more explanation I am trying to edit the default squishdot screen which uses tinytable. the screen depends on dtml files under squishdot/demo/rightbox_methods for instance. I change these methods and the changes do not appear in my current squishbox instance. If I add a new squishbox the changes are seen. Clark
