Access Control Advice
by John Eikenberry 12 Mar '99

12 Mar '99

Hello all, I am working on a Zope app, and would like to see if anyone has any tips for how I should handle access control in this situation... The site is a corporate organization site. It has many corporate members, each has an admin which has control over a subset of information kept in a relational database. I want to have just one role (comp_admin) for this. But each company can only have access to their company info. Thus I need to check that the admin belongs to that company. (there are also regular users who also have to login. they can view, but not modify) The users, passwords and roles are kept in the database too (UserDB). Each company has a unique id, and this is the primary keys in the DB. Each user is associated to the company using this id (a field in their table). Make sense? My current idea is: 1. Have a general main page which both users and admins login to. If they use the admin login, get their company id (comp_id) and create a link to the admin section using the magic of direct traversal (this way they can bookmark the admin page). Eg. <a href="/comp/1/admin/">admin section</a> ('comp' is the zsql method, 1 is the comp_id, admin is the folder) Thus the comp_id of the company will be available, and I could: A. I could then (mabey?) use the comp_id in the UserDB query (in the admin folder) to only retrieve those people belonging to that company. OR (if I can't get to the comp_id from the UserDB query). B. I could then compare to the person's comp_id to the company's comp_id in each of the effect pages via a new standard_header. Thoughts? Better ways to do this? --- John Eikenberry [jae(a)kavi.com - http://taos.kavi.com/~jae/] ______________________________________________________________ "A society that will trade a little liberty for a little order will deserve neither and lose both." --B.

Gentlemen, I am very pleased with Zope and in an effort to support it, I will create a channel called #zope under the EFnet. I am still learning about ZOpe, but I will try to help all I can. Also, I will be placing an infobot to provide lots of information on Zope. Drop by and pay a visit to #zope if you have some time...

This is a buglet in ExternalMethod where an exception has been raised and caught by ExternalMethod, and EM is looking at the values of the traceback for some special conditions. It's trying to do a string.lower() call on one of the values that in Python1.4 was always a string, but in Python1.5.x is an instance (in Python 1.5, standard exceptions became classes). This has been fixed and will be in the next release. .jPS | jeffrey(a)digicool.com zope, through the web. www.zope.org

Getting slashdot to work...
by Tony McDonald 12 Mar '99

12 Mar '99

HI all, In my quest to figure out how Zope works, I'm starting with ExtrenalMethods. I've moved slashdot.py into Extensions and set up an external method (id: get_headlines, funstion name: get_headlines, python module: slashdot). My 'calling' DTML is a method (slashdot_headlines) with the following;   <p> <a href=""></a> </p>  trying 'view' on this method gives the following;  ...  I *did* have a problem with using a proxy, but got around that by adding this line to slashdot.py (just before the urllib.urlopen() call). urllib.URLopener(proxies={'http': 'http://cache-box.you.domain:your_port'}) What am I doing wrong? many thanks tone ------ Dr Tony McDonald, FMCC, Networked Learning Environments Project The Medical School, Newcastle University Tel: +44 191 222 5888 Fingerprint: 3450 876D FA41 B926 D3DD F8C3 F2D0 C3B9 8B38 18A2

If implemented like the Apache JServ module (http://java.apache.org/) it should solve a lot of problems for everyone, adding performance to boot. JServ is in effect a separate process (like Zope) that receives it's request via the Apache server, with the help of a module, that translates the requests into socket calls. If someone modifies the module that comes with JServ to call the Zope process instead of the JServ process..... -- M.J.

RE: [Zope] Tree Tag & SQL

Hi Ron. Just a guess, but how about having the tree tag pass in the the current level as an argument to the same SQL method, then have the SQL method adapt itself based on the argument? Remember that an SQL method can embed logic and act like an object using DTML. For instance:  select ...  select ... etc. --Paul
