I thought that my "standard_html_header" in my top level would suffice as the "start" method, and my "navigation" method is similar to the "voodoo" method. My public interface "index_html" is a dtml document. When i changed "index_html" to a dtml method everything worked. So now from within "index_html" i just call " to render the content. It is still peculiar to me why "Objectvalues('Folder')" has no values when you call it from a dtml document but has values when you call it from a dtml method. Why is this the case?

Hi, -----Original Message----- From: Roché Compaan <sparroy(a)adept.co.za> To: Michel Pelletier <michel(a)digicool.com>; Zope <zope(a)zope.org> Date: Sunday, August 22, 1999 10:40 AM Subject: RE: [Zope] Recursive method (Funny-peculiar) >It is still peculiar to me why "Objectvalues('Folder')" has no values when >you call it from a dtml document but has values when you call it from a dtml >method. Why is this the case? You have hit upon the difference between a DTML Document and a DTML Method. A DTML Document has its own namespace. That means that any properties you reference are looked up in the Document first. A DTML Method uses the namespace of its container. So, with the DTML Document, when you call "objectValues('Folder')", it is looking for Folders within the Document. (Which you won't have, because DTML Documents are not object containers). When you call "objectValues('Folder')" from a DTML Method, the objects within the Folder itself are looked up. There is more of a discussion of this at: http://zdp.zope.org/FAQ/product_builtin Kevin

UserDb weirdness update
by Tony McDonald 22 Aug '99

22 Aug '99

Hi, I posted a while back about problems I was having with UserDb and cookie authentication (basically a LoginRequired exception being raised that was causing 'an error has occurred' message when I tried to access a page that was restricted). Here's my latest observations - once I have time, I'll write up what little I know as a HowTo on UserDb. I had a folder structure Actors Upload acl_users (a UserDb object) docLogin (these are all properties of the UserDb object) docLogout sqlListQuery sqlUserQuery .... sqlmethods index_html (no acquired permission for 'view', anonymous:view = off, Owner:view = on etc.... index_html is where all the stuff goes that I want authorised people to see. Accessing this URL /Actors/Upload always produced the 'an error has occurred' message. As a test I created a new folder, put a UserDb object in it and made an index_html document with these permissions index_html (no acquired permission for 'view', anonymous:view = off, Owner:view = on ie junk UserDbTest acl_users (a UserDb object) index_html (view permission off, etc. etc.) accessing *that* folder (/junk/UserDbTest) *did* work as expected. To cut a long story short I basically exported *each* individual object in the Upload directory bar the acl_users folder and reimported them into another folder (Upload2). I then created a new UserDb object in the *Actors* folder (ie acl_users) and edited the sqlListQuery and sqlUserQuery SQL queries so that they were pointing at the right database. It looks like this; Actors acl_users Upload index_html sqlmethods etc... Things now work, although I have no idea why (which is a *bit* of a worry...) One thing that *might* be useful for others is that the docLogin document is *included* into the document that needs authentication, at least that's the way it's worked for me, ie; standard_html_header shown from *my* acquisition tree contents of docLogin standard_html_footer shown from *my* acquisition tree This means y'all want to be careful with docLogin, strip away it's <html><body> and </body></html> tags and just leave it bare with the FORM HTML. A bit ramblin' I know, but I hope this helps some people out. If anyone who's more au fait with UserDb can point out the glaring, idiotic, ne'er to be repeated spasm of ineptitude that I've committed - I'll be grateful, honest!. Tone.

manage_clone gives permission error since Zope2
by Florian Mueller 22 Aug '99

22 Aug '99

Hi there! Since we upgraded to Zope 2.0.0b4, I have major troubles with "manage_clone" in a product which worked fine before. Whenever I try using it, I get permission errors, even the superuser cannot use the method that worked fine before. Assuming I did something wrong, I took the Zope Content Manager Guide and typed the Plutonia example in again. It uses "manage_clone" as I do in my product. I ran this example, and hey! It did not work and gave the same weired "ApplicationDefaultPermissions" errors and stuff like that. I tried login as a superuser, and again I got authorization errors. First of all I though the error must have to do with wrong permission settings of my role, but than the superuser should not get an error, right? I also don't understand the new "mapping" permissions in the products since Zope2. Any clarification? Thanks, Floyd -- http://floyd.va.com.au

BUG (?): Default file names...
by Sven Kirmess 22 Aug '99

22 Aug '99

I don't know if this is a bug in Zope 2..b5 or a feature, but I don't like it. [test] |-- DTML: menu.html |-- DTML: m.html | |--[sub] |-- m.html ------------------------- /test/menu.html <html><head></head><body>  </body></html> ------------------------- When I call /test/menu.html , everything works as expected, but when I call /test/sub/menu.html, the file /test/m.html is inserted in menu.html and not /test/sub/m.html. In version 1 the file /test/sub/m.html would be inserted... Is this ab bug or a feature I can deactivate? btw: Properties behave in the same manner (as opposite to version 1).

dtmlExamples
by Herman Cuppens 22 Aug '99

22 Aug '99

I have dowloaded Zope (Zope-1.10.3-3.src.rpm) and successfully installed it a week ago. Been fooling around some days and was really impressed. Now thought, I was ready to see some examples, so I downloaded the "dtmlExamples.tgz" from the Contributed-page at http://www.zope.org. I did read the included README_DTMLExamples.txt, but every attempt to execute the "manage_hackImport" failed, giving "Sorry, ...blabla Error type: cPickle.UnpicklingError Error value: invalid load key, 'G'. ". Trying several ways (Import/Export from control-panel, opening url with manage_importHack all give the same result, although they expected the inputfile to be in different places (varying from var/import, var/zope). Finally, I am getting this error-message and I really have no clue how I should proceed now, can anyone help me ?

BTW, I haven't figured out the >purpose of  and ends at "> (note the "> there). You can have whitespace _within_ the DTML tags, but not in between them. Putting the whole thing on one line will solve your problem. The  will insert the path to your Zope installation. This is only really necessary for sites using Apache or another Webserver, where the Zope root folder is not ate the root of the website. If you can reach Zope through the URL 'http://your.site.com/Zope/' then SCRIPT_NAME will be '/Zope'. This way you are sure that wherever you place this script, you will always be able to reference the icons properly. -- Martijn Pieters, Web Developer | Antraciet http://www.antraciet.nl | T: +31 35 7502100 F: +31 35 7502111 | mj(a)antraciet.nl http://www.antraciet.nl/~mj | PGP: http://wwwkeys.nl.pgp.net:11371/pks/lookup?op=get&search=0xA8A32149 ---------------------------------------------

Recursive method
by Roché Compaan 22 Aug '99

22 Aug '99

I want to use a recursive method do draw the navigation tree for my site. I do not want to use the tree tag to iterate through the subfolders because the question-mark in the tree-query might obscure pages of the site to search engines. How can one call a method from within a method passing variables to that method? How does one define a method which accepts certain parameters eg. if someone can translate this in to dtml for me this would be a great help: recursive-dmtl-method(variable folder) in folder if document then makeHREF to document if folder.hassubfolders then recursive-dtml-method(folder) -------------------------------------- This would be of great help.
