Re: [Zope] zForum problem
OK - I am stumped! I have just created a zForum in my root folder without a hitch. The problem is nothing to do with the root folder acl_users folder or the database connection. It has to be something to do with CookieCrumbler. Check you only have one installed (I assume you are not using Plone). Check the version - mine is CookieCrumbler-1.2. Have a look in __init__.py and CookieCrumbler.py to check they both have manage_addCC references (i.e. have not been corrupted). Check that files in the CookieCrumbler folder have read permission for the zope user. You say the error keeps popping up again and again. Do you mean it pops up many times during one installation attempt, or just once for each of many attempts? I this doesn't help you will need help from zForum or CookieCrumbler experts. Did you try not checking the Create user folder checkbox? That leaves out creation of acl_users so may not bother with the addCC call. Cliff H Jansen wrote:

Cookie Crumbler is in the 'Add dropdown' list.

The error message:
""" Site ErrorAn error was encountered while publishing this resource.

keeps popping up again and again. The zope manager's password in acl_users is different from that used in the database connection string; that can't be the problem can it...?

and the error message is saying that it can't find manage_addCC in CookieCrumbler (I have taken out the rest of the Error log from this reply because it contained a plain text database connection string).
Check that your Add dropdown list has Cookie Crumbler (Standalone) in its list and that the Zope user has read/write access to the CookieCrumbler and zForum folders.
I have a test zForum installed and it just worked! If I create another with a dud database connection string I get a database error when trying to View (the installation appeared to work OK).

The Site Error message keeps popping up all the time (...sigh). Anyone some idea what's wrong...?

I'm using CookieCrumbler.py 1.18.10.1 from CMFPlone-2.0-final (I'm using Plone indeed, yet at a lower level in the folder hierarch). The error pops up just once for each of many attempts. Also you say "...CookieCrumbler folder have read permission for the zope user." I can't see the CookieCrumbler object is a folder (when I clikc it it's just a "Cookie Crumbler" object with some properties). However, in the zForum instance creation form when I switch off the checker box for "Create user folder" I get past the previous error (at line 142 in zForum.py). Instead, I obtain the following error message: """ Site Error An error was encountered while publishing this resource. Error Type: UnboundLocalError Error Value: local variable 'files_dir' referenced before assignment """ with traceback in the Error Log file: """ Time 2005/03/23 17:27:33.398 GMT+1 User Name (User Id) zope (zope) Request URL http://localhost:8080/manage_addProduct/zForum/manage_addZForum Exception Type UnboundLocalError Exception Value local variable 'files_dir' referenced . before assignment Traceback (innermost last): * Module ZPublisher.Publish, line 101, in publish * Module ZPublisher.mapply, line 88, in mapply * Module ZPublisher.Publish, line 39, in call_object * Module Products.zForum.zForum, line 87, in manage_addZForum * Module Products.zForum.zForum, line 116, in __init__ * Module Products.zForum.zForum, line 173, in zfSetupSystem UnboundLocalError: local variable 'files_dir' referenced before assignment """ Around line 173 the zfSetupSystem method (in zForum) reads: ... for k in [INSTANCE_HOME, SOFTWARE_HOME]: location = os.path.join(k, 'Products', 'zForum', 'www', 'forum_main') if os.path.exists(location): files_dir = location for file in os.listdir(files_dir): # line 173 ... Apparently, in my session "os.path.exists(location)" evaluates to false, files_dir becomes undefined (it's not defined before) yielding the runtime error at 173. To me this looks like a bug... As regards my problem, I can conclude that zForum creation seems to get past the manage_addCC method when no user folder is created. What can we learn from this. ...?
