It took me (as a Zope newbie) quite a bit of time to get zForum working in my non-standard setup. The causes were twofold: 1) Incorrect CookieCrumbler import when using the one from CMFCore (instead of standalone) 2) zForum doesn't reckon with non-default 'Products' directories (these can be set by the 'products' variable in zope.conf -- as it happens in my case). I've send an updated version to zForum developer Julian Flores (jflores@codeit.com). I expect a new version will come out some time. Citeren "burley@zonnet.nl" <burley@zonnet.nl>:
OK, I solved the next problem (first was a bad CookieCrumbler import in the zForum.py module):
In my zope.conf setup, I've set 'products = my_products_path' where of course zForum was installed (and shows up in the ZMI 'add Products list'. However, when a zForum object is instantiated, the zForum module only looks in Zope's default product path (.../instance/Products); hence my undefined 'files_dir' variable! Here's the zForum patch:
from Products import __path__ # list of all the products paths (default and set in zope.conf)
and replace (at line 172):
for k in [INSTANCE_HOME, SOFTWARE_HOME]: location = os.path.join(k, 'Products', 'zForum', 'www', 'forum_main')
with:
product_paths = __path__ product_paths += [INSTANCE_HOME+'/Products', SOFTWARE_HOME+'/Products'] for k in product_paths: location = os.path.join(k, 'zForum', 'www', 'forum_main')
This solves number 2. ... Up to problem number 3: at zForum instantiation now I get the error traceback (much deeper in the zForum.py module): """ Request URL http://localhost:8080/mfts.nl/manage_addProduct/zForum/manage_addZForum Exception Type AttributeError Exception Value addAnnouncement
Traceback (innermost last):

AttributeError: addAnnouncement """ where line 2469 corresponds in my patched zForum.py file with the line: """ zforum.sql.addAnnouncement.manage_permission('Access contents information',('Manager', 'Reviewer',),0) """ Apparently, the zforum.sql object has no addAnnouncement attribute in my case. Why not?

Confirmation: I do have the Stand Alone version of CookieCrumbler, used just to test out zForum, and mentioned in my message (below), but I know
this subtle difference may not have been obvious.

I had five minutes, so I tried this too, and it also didn't work for me.
I tracked the error down to line 55 of zForum.py
Instead of: from Products.CMFCore.CookieCrumbler import CookieCrumbler
it should be: import Products.CMFCore.CookieCrumbler
The manage_addCC method is in the module, not in the class.
I suspect people for whom this works have the standalone CookieCrumbler product, not the one included in CMFCore?
Thanks, Malcolm.

I've gone through your details, yet I'm still stuck ;-( :
Cookie Crumbler is in the 'Add dropdown' list. Further, I try to keepthings simple as possible: zForum creation in root folder ("/"), singleacl_user ('zope', who is the Manager and by default has all permissions including read/write permissions.); these all are aquired by CookieCrumbler, zForum folders however do not exist at this stage since zForum doesn't get past its instantiation. The error message:
""" Error Type: AttributeError Error Value: manage_addCC """
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 theproblem can it...?
Citeren Cliff Ford <Cliff.Ford@ed.ac.uk>:
Forgot to cc the list in the last reply. Line 142 of zForum.py says:
CookieCrumbler.manage_addCC('cookie_authentication')
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).
