Thank you, Jamie. I gather it is better to use /Control_Panel buttons (than stop and start scripts in zope directory).

Depends which version of zope you're using, and how you have it set up, but generally - no it doesn't do the same thing; the stop and start scripts use signals, the restart button triggers a more gentle shutdown and exits in such a way that zdaemon knows it should restart everything. -- Jamie Heilman http://audible.transient.net/~jamie/ "It's almost impossible to overestimate the unimportance of most things." -John Logue

RE: [Zope] Help with tree tag and localfs

It's all good! I found the Tree property options in my searches, but nothing said you also had to check Catalog, which is what threw me off. I plan on reviewing your scripts as examples for my own use, but I have to learn more Python. For someone coming from a VB background, it's confusing, but I'll figure it out. I appreciate the time you took to help!

By default these display container only AFAIK. You can use objectValues and objectsIds instead as you did. Also my fault I should have mentioned the Catalog and also the TreeDisplay properties of the LocalFS product. You can generate the text that you see in the tree including icons. For example you can see my attempt here : http://nbs.neuro-bs.com/ex_files/expt_view?id=46 In my example <dtml-var "pres_docs_get_url( getId(),hasChildNodes(), _['tree-item-url'], _['tree-item-expanded'])"> is what generates the icons and links.

problems with ZpdfDocument
by john.strunk＠newmediadzine.com 03 Apr '03

03 Apr '03

Hey guys, I am having a bit of trouble with ZpdfDocument package from: http://www.zope.org/Members/gaaros/ZpdfDocument I follow the instructions and untar & zip into the zope directory but upon startup i get the following errors: PROBLEM(100) Init Ambiguous name for method of Products.ZpdfDocument.ZpdfDocument.ZpdfDocument: "manage_main" != "manage_editForm" PROBLEM(100) Init Ambiguous name for method of Products.ZpdfDocument.ZpdfDocument.ZpdfDocument: "manage_main" != "manage_editDocument" PROBLEM(100) Init Ambiguous name for method of Products.ZpdfDocument.ZpdfDocument.ZpdfDocument: "manage_main" != "manage" Specs on Zope server are: Zope version 2.6.1 (binary release, python 2.1), python 2.1.3, RedHat Linux 8.0 I was wondering what these errors meant and how, if possible, to fix them. I have searched everywhere for a new version of this package but I have found none. I have also found no other people posting this problem with ZpdfDocument and even sites that are still offering the service so I know it can be run on a new version of Zope. I imagine the problem is that Zope has changed sence ZpdfDocument's release date (99') and thats where the problem is. If you have any ideas on how to fix these errors let me know. I would also apreciate any info you guys may have on any similar packages that will accomplish the same tasks ZpdfDocument does if I have to choose another package instead of ZpdfDocument. ------------------------------------------------- This mail sent through IMP: http://horde.org/imp/

Zope-2.6.1( VirtualHostMonster + CookieCrumber + absolute_url)
by Felipe Barousse Boué 03 Apr '03

03 Apr '03

Hi all: I do need form authentication and I am trying to make a CookieCrumbler (latest version 0.5) work within a Zope site behind Apache 1.3.27 implemented with only one VirtualHostMonster at the root folder level. My folder's structure is like: root-- site1 CookieCrumber logged_in logged_out index_html acl_users exit_html The default login form (a CookiCrumbler property) is actually index_html which in turn uses "logged_in" after some page formatting (CSS and such.). The default log out method (another CC property) is "exit_html" which in turn calls a <dtml-call "cookie_crumbler.logout()"> which in turn, at the end (from the CookieCrumbler machinery) -supposedly- calls the "logged_out" method. If I get into the site through the 8080 port, everything works like charm, nevertheless if I get into the site through Apache (port 80) and hence using the VirtualHostMonster machinery, the CookieCrumbler starts behaving oddly, specially what concerns to the logout process. When logging out, the URLS and paths get effectively rewritten/mapped to: www.site1.com/logged_out instead of: www.site1.com/site1/loggedout. Therefore, logged_out is never found even tough "exit_html" was executed and (presumably) the <dtml-call "cookie_crumbler.logout()"> was executed also. I got rid of all "absolute_all"'s within my application code as to avoid problems with the VirtualHostMonster. I have checked the CookiCrumbler code and it uses absolute_url() within its code (in def logout(...) for instance. I think this usage of absolute_url is what is messing things up. I know I can play around with VirtualHostMonster mappings and solve the problem somehow. but, the overall questions are: 1.- What is the best way to work with VirtualHostMonster and code that uses absolute_url(). 2.- The preffered and correct use of CookieCrumbler (with VHM installed) would be....? Calling <dtml-call "cookie_crumbler.logout()"> is the propper way to "logout" using CC ? 3.- Any special suggestions for the above settings would be appreciated. I know about basic authentication not having/knowing of a "logout" concept. I also know about CookieCrumbler simulating the login/logout with the setting/expiring of cookies and only "intersecting" with with the HTTP authentication where required to make this work. Thanks in advance for your comments and assistance. Best regards. -- Felipe Barousse Boue. CEO - Director General Piensa Technologies - Bufete Consultor de Mexico www.piensa.com

how to create a module global variable ?
by Jerome Alet 03 Apr '03

03 Apr '03

Hi, I'd want to create a variable which is shared by all instances of a Python class of my own. What I've done is that I've put the following line : _MySharedVar = None outside of any method or class definition, at the top of the python file which defines my class. I've done this because after having looked at Zope's sources, there are lots of _marker=[] there, and I guessed that's what I wanted to do. but then one method of my class has to initialize this variable if it is equal to None (meaning not yet initialized), but in the following code : def myMethod(self) : """My method.""" if _MySharedVar is None : _MySharedVar = "yes" the "if" raises and UnboundLocalError, saying that I use _MySharedVar before assignment. I've tried to delete my product from the ZODB and restart Zope, delete and recreate my class instances, but the problem persists. What is the problem ? In Zope's sources, _marker is used directly without any "global" keyword use. Do I need to use the global keyword ? If yes then why ? If not then what did I do wrong ? thanks in advance Jerome Alet -- (c) 1928-???? The letters U, S, and A and the U.S.A. flag are the copyrighted property of Disney Enterprises Inc.

Oh, that's OK, I appreciate the input. Besides I learned more by trying your exammples. I did figure out my problem today, though. Under the LocalFS object's properties, I had to select 'Catalog' to make it work. Once I did that, the dtml-tree worked fine. <dtml-tree zinesfolder branches="objectValues" sort="meta_type"> <img src="<dtml-var icon>"> <a href="/zinesfolder/<dtml-var tree-item-url>"><dtml-var id></a> </dtml-tree> If I used this: branches_expr="objectIds()" it didn't work. (as in nothing displayed, but I didn't get any errors.) I noticed that the LocalFS objects don't have the same properties(like title) as they do in Zope. I should expect that since they aren't actually "Zope" objects, rather LocalFS objects. Now I just need to figure out how to get better icons to display, but that's not urgent. Thanks for your help!

Newbie - installing DirectoryStorage.
by FNk 03 Apr '03

03 Apr '03

Hi all, I'm having problems installing DirectoryStorage (both the stable and beta versions). I'm running zope-2.6.0 on a Linux Redhat distribution with a ext3 filesystem. The installation seems to be going well (e.g. everything get installed without error), but when a start Zope, I can't manage to logon. I run zope with the -u switch. Apparently, "the best workaround is to drop root privileges sooner, before starting Zope". Can somebody tell me what this means exactly ? cause I believed that I've tried this but without success. My second question is: Is there a way of installing Zope without having to use the -u switch ? Thanks for any help. FNk

Mozilla User Agent and WebDAV
by Brian Brinegar 03 Apr '03

03 Apr '03

Howdy, We have a Zope server behind an Apache Server. The Apache Server has rewrite rules that check User Agents and redirect WebDAV clients to the WebDAV port on the Zope machine. We would like to do this with Moziilla Composer. However Mozilla composer sends the same User Agent as the Mozilla browser (As best I can tell). Has anyone run into this? Is there a way to differentiate between Mozillas browser and composer? Thank you, -Brian Brinegar ECN Web Systems Developer Purdue University
