Is there a better way to code this?
by Luke Tymowski 03 Jul '00

03 Jul '00

Hello, I'm still having trouble trying to get Zope to use/ignore header and footer code in the appropriate places. To have Zope ignore the footer code in one place but still display footer code on other pages, I've resorted to this: <dtml-with history> <dtml-with 2000> <dtml-in "objectValues(['DTML Document'])" size=3 sort=title reverse> <dtml-call "REQUEST.set('renderedfooter',1)"> <dtml-var sequence-item> <a href="/history/2000/<dtml-var id>" title="Permanent link to the entry for <dtml-var title>">PermaLink</a> <br> <br> </dtml-in> </dtml-with> </dtml-with> <dtml-call "REQUEST.set('renderedfooter',0)"> My problem was that on the first sequence item returned, Zope would insert the footer code. On items 2 and 3, Zope would not display the footer code, and, again, at the end of the page, when I did want the footer code to appear, it wouldn't. I had no trouble with the header code. I assume it had no trouble with the header code because by calling it to display that document itself, Zope inserted the code and set the renderedheader to 1, causing it to be ignored elsewhere in the document, as it should. So. Is there a better way to do this? Or is the above meet and right and not worthy of shame? I want to write a How-To so other newbies don't have to go through what I did. thank you, Luke

Oracle 8.1.6 setup file for DCOracle
by Kiran Jonnalagadda 03 Jul '00

03 Jul '00

I've just put together a setup file for Oracle 8.1.6. I started with including all the libraries in Oracle's library directory and then removed the ones that gave me errors. It works fine except for when I present an SQL query with a syntax error. That makes Zope crash. Anybody know why? -- Kiran Jonnalagadda http://lunateks.com baby.sh: while true; do echo "^G^G^G^G^G"; sed -e 's/food/poop/'; sync; sync; sleep 15; done *shared* # Setup file for Oracle 8.1.6 (Tested for Linux on Intel). # # Unfortunately, the libraries needed to link Oracle change from revision # to revision. # # Oracle provides a make file for building "demo" programs in # $ORACLE_HOME/rdbms/demo/demo_rdbms.mk.

ZClass in ZClass problem
by Oleg Broytmann 03 Jul '00

03 Jul '00

Hello! (Nobody dared to answer, retrying...) I started to learn ZClasses. I created a product, added a Zclass in it, and added a Zcalss inside outer ZClass - I want to create ZClass that's addable only inside outer ZClass. Then the problems begin. All management URLs for inner ZClass contain %20, so URLs look like "propertysheets/methods/RandomZItem%20/manage_workspace" and "propertysheets/methods/RandomZItem_add%20/manage_workspace". If I click on the link I got the AttributeError (of course). When I manually remove the offending %20, I can manage the object, but it's tiresome to remove it every time. The problem manifested on both 2.1.4 and 2.2.0b3. What's wrong? Oleg.

Re: [Zope] ZClass beginners question

Hello, Dierk, There are several ways to use a relational database from within Zope. A good start for you would be the Zope SQL methods. Read the documentation about them at <http://www.zope.org/Documentation/Guides/ZSQL-HTML/ZSQL.html>. Then experiment. When you get stuck, ask questions on this forum.

Re: [Zope] Why can't I subclass a ZSQLMethod?
by Ivan Raikov 03 Jul '00

03 Jul '00

What do you mean, you cannot get a view to it? I can change in the management area. I believe ZSQL methods are not supposed to provide the user interface; you use them the way you would use an external method. That means you have to create the form that sends the query parameters to the SQL method, and you have to write the DTML code that obtains the result set, and displays it accordingly. At least that's way I do it; there might be a better way, I don't know. Best, Ivan "Cary O'Brien" <cobrien(a)Radix.Net> writes: > I tried that.

Comments on 2.2 Help System
by Chris Withers 03 Jul '00

03 Jul '00

Apart from the 'Wow! Zope has Help!' comment: The API documentation is very useful. How do we feedback about it? (eg: why is there PropertySheet and PropertySheets?) When will it be complete? How do we submit docs to appear in it? What is the moderation process like? Sadly, the rest of the 'Zope Help' section needs a lot more structure to be useful. At the moment, the names don't even fit in their browser pane :( Perhaps something along the lines of the portal structure on zdp.zope.org would be useful for categorising these documents? If these are the 'help screens' you get when you click the help button, maybe they shouldn't be listed here at all? I have to say, I think the M$ help system on Windows might be a better model: 1. A Contents Page - kindof like the zdp portal listing, or a contents section of a book. 2. An index page - A list of all the documents in the help system, which seems to be largely what the 'contents' tab is now. 3. Search - which needs to be explained better than it is. Can boolean searching be used? Do I need to quote things? How do I search for dtml-in? (Maybe a help screen would be useful ;-) Maybe there should be links to the Contents Page as well as help on your current location from in the management interface? Finally, you should make it clear elsewhere that /HelpSys on your site will go to the Zope help system. Maybe this needs to be blockable, after all, why should www.mysite.com/HelpSys give the Zope help system, when I might want it to be my company's help system for their products? Which suggests that maybe the help system should be a separate product from Zope, running on its own server. For example, take a company which has LOTS of zope servers. The sysadmin would prefer to maintain one up-to-date copy of the Zope docs on a 'documentation server' which has documentation for all the Zope versions in use, rather than wastefully running the same number of documentation servers as there are Zope instances... ...heaven forbid, DC could actually run a master one of these at doc.zope.org which would be the most complete and up to date... Views? cheers, Chris

User Management Styles
by Chris Withers 03 Jul '00

03 Jul '00

Hi, I've noticed two styles for managing users in Zope. 1. Have one User Folder in the root of your Zope instance and then manage what users can do through Local Roles (PTK and Zope.org spring to mind) 2. Have user folders at each level of your content tree. This is as recommended in the ZCMG and otehr older docs. The question is, which method is better? My comments would be: 1 is better if the site is 'managed' by a system such as PTK or uses components such as LoginManager that are non-trivial to setup. 2 is better if you REALLY want to delegate authority for subfolders. The obvious one is Zope ISP's with more than one client per instance of Zope. Please not the 2 currently has serious problems (see the 'Every user should have the Anonymous role everywhere' thread) and I'm sure I remember readign about bugs with Local Roles (btu I expect they've all been fixed by now...)# Comments?
