RE: [Zope] repost: Zope on Windows 2000 won't start

We haven't tried Zope out internally on win2K yet, so I can't really speak intelligently on the matter right now. But, since that's never stopped me before... :^) The win32 service support is based on Mark Hammonds win32 extensions (win32service in particular). A good place for an enterprising individual to start would be to take Zope out of the picture by installing a clean Python1.5.2 on win2K with the win32 extensions and see if any of Mark's win32 service demos (I believe there is at least one) will run. If anyone takes me up on this, I'd be _very_ interested in the results (as I won't have time for a while yet to get to this myself). Hope this helps!

Bug in object security?
by James W. Howe 22 Feb '00

22 Feb '00

I've encountered a strange behavior with the Zope security mechanism which strikes me as a bug. Here is what I've done: 1. Create a folder in root named 'AccessTest' 2. Create a user folder in AccessTest 3. Define a role for AccessTest called 'Publisher' 4. Create a user in the acl_users directory and grant the user 'Publisher' access 5. From the AccessTest security tab, disable 'Access contents information' for anyone except the manager. 6. From the AccessTest security tab, enable 'View management screens' for Manager and Publisher. From a fresh browser (no previous authentication), attempt to access the management interface for AccessTest (i.e. http://foo.com:8080/AccessTest/manage) Log in as the 'Publisher' user. The screen displaying the contents of the AccessFolder will be displayed. However, this is where I think a mistake has been made. In ObjectManager, the 'View management screens' has been associated with manage_main and manage_menu. Similarly, ObjectManager defines the 'Access contents information' for the methods objectIds, objectValues and objectItems. When I disable 'Access contents information' for my Publisher role, it would seem that users with this role should not be able to access these methods. However, the manage_main dtml code which defines the contents view of the management interface makes use of these methods. When the manage_main dtml is rendered, why doesn't Zope prompt for authentication when manage_main attempts to access objectItems, for example? I'm sure there is a very reasonable explanation, but it strikes me as odd. Thanks. James W.

changing sizes of Property Sheets/Views
by Andrew Diller 22 Feb '00

22 Feb '00

I've got some ZClasses, Property Sheets and views set up. I'm populating instances of my classes.... but when I want to come back and edit them, I'm using the management screen of the instance, and its default view, created I guess from the Property Sheet that I created. How can you change the sizes of these fields? For instance, I specified one attribute as a text, but the resulting textarea is too small to work with. Or am I approaching this wrong- should I be creating DTML methods that read the values and edit them in a form I write as a method, then update the instance. Right now I'm directly trying to edit the View that was created. I'm basically following the Developers Guide, with the ZClasses Howto filling in most of the blanks. -andy - - - - - - - - - - - - - - - - - - - Andrew Diller dillera(a)isc.upenn.edu Information Systems and Computing Unix Systems Group University of Pennsylvania v: 3-7360 f: 8-9348

A newbie question...
by Carlson, Christopher W. 22 Feb '00

22 Feb '00

I've just installed the latest version of Zope and, following one of the how-tos managed to get ZMySQLDA and MySQLdb installed and working. I've been using Apache and PHP, and am interested in exploring how migrating my web site to Zope can benefit me. Unfortunately, I've run into a snag. A summary table on one particular part of my site is constructed thusly: I have a table 'names' containing, in each row, a name, an ID, and an 'active' flag. Another table, 'money', contains an ID and a dollar amount, representing adjustments to the associated 'account'. A final table, 'action', stores an ID and a number of hours worked. For each name in 'names', the total number of hours worked is computed and multiplied by a fixed amount to create a value 'earned', and then added to the total dollar amount in 'money'. Then, each row of the HTML table shows the ID, name, total hours, 'earned' amount, adjustments, and the final balance. I'd like to continue storing the information in the MySQL database that it currently resides in, but I'm having a heck of a time understanding how to structure my SQL methods. Can anybody drop a hint, or point me towards a document that'll help me understand how to proceed? (For what it's worth, I can use the Search Interface Wizard to perform queries, but doing sub-queries within the generated method isn't intuitive to me at all--is that even the right approach?) --- Chris Christopher W.

Max Length for 'text' property???
by Jonathan Cheyne 22 Feb '00

22 Feb '00

Ouch! Just got bit by this thing ... created quite a few zclasses etc all looking good however I only subclassed Catalogaware and Renderable and not DtmlDocument because of sub cataloging problems I was having. Is this the problem - not having a suitable subclass to contain longer text entry? I have a text property called body that I was trying to use to contain any text content for tha instance ... I have a site to present tomorrow and am stumped - anybody have any ideas? Have I gone about this rather rashly?? I /need/ catalog aware and so don't want to use dtml document. Staring disaster in the face Jonathan

I like to comment my code and I find myself wanting something a little more flexible than the <dtml-comment></dtml-comment> convention. What I think would be nice would be a way to embed a comment into any dtml tag. Here is my suggestion: <dtml-var some_money_variable fmt='dollars-and-cents' // everything from the double slash to the ending greater than bracket is a comment> I program a lot of javascript and am acustomed the // for comments, but any kind of simple trigger is fine by me.

Trying to understand __roles__
by James W. Howe 22 Feb '00

22 Feb '00

In previous e-mails I've described a problem that I've been having with my management tabs. I have a subclass of Folder which is displaying the Contents tab even though the currently authenticated user shouldn't have access to it. If my folder defines it's own "manage_main" instead of inheriting it from ObjectManager, the Contents tab is not visible to users who shouldn't see it. After spending some time with the debugger, I found the following bit of information: If I inherit manage_main from ObjectManager, when the object representing manage_main is asked for its '__roles__', it answers a list of ['Manager', 'Publisher', 'Manager']. I don't exactly understand where this information comes from, and, more importantly, why it contains my 'Publisher' role. If I define manage_main in my Folder subclass, however, asking manage_main for its '__roles__' answers ['Manager']. This seems like the correct answer to me. I have the feeling that there is some key concept about Zope and/or Python that I'm not getting. Why does the inherited manage_main have different __roles__ than if I define it in my subclass? How would it have managed to pick up a role (Publisher) that hasn't been assigned to it (to the best of my knowledge)? Finally, can someone tell me where I can see how __roles__ is implemented? I can't seem to find it. Thanks. James W. Howe mailto:jwh@allencreek.com Allen Creek Software, Inc. pgpkey: http://ic.net/~jwh/pgpkey.html Ann Arbor, MI 48103

Help with etcUser Folder
by Joseph Santaniello 22 Feb '00

22 Feb '00

Hi, I'm running RedHat 6.1 with neither shadow, nor MD5 passwords, and I can't get the etcUserFolder product to work. I try creating an etcUser folder, I specify the /etc/passwd file and then it creates successfully, but no users are shown, and after specifying security levels on some other object to test it, the authentication doesn't work. It just keeps popping up the password dialog until 3 tries, and then gives an authentication error. Normal User Folders work fine. The Readme says that the cryptmodule.so might not work so I replaced it with the cryptmodule.so from my Python installation. Still no-go. Any suggestions on what I should try next? Thanks, joe

Zope Python Inheritance Question
by James W. Howe 22 Feb '00

22 Feb '00

In looking at the implementation of Folder, I see that it includes Collection as one of its base classes. Folder also includes ObjectManager as one of its base classes. ObjectManager itself includes Collection as a base class. Is it redundant to have Folder derive from the Collection class? Just trying to figure this stuff out... Thanks. James W.
