Zope refuses to update file contents
by Mitch Pirtle 18 Sep '03

Hi list, I have someone here using the ZMI (direct, not proxied through apache) to update PDF files that are stored in the ZODB. The wierd part is this: 1) (from ZMI) select File 2) hit 'Edit' tab 3) 'Browse' to new file on local drive 4) 'Upload' When she is done, she hits the 'View' tab and sees the old document. So I deleted the file altogether from Zope, and created a new one in its place. It is still the old file. ?!?!?!?! There is no caching turned on AFAICT. The culprit is: Zope 2.6.1 (binary release, python 2.1, linux2-x86), python 2.1.3, linux2 2.1.3 (#1, Sep 19 2002, 13:15:46) [GCC egcs-2.91.66 19990314/Linux (egcs-1.1.2 release)] Any ideas, o amorphous mass of Zope knowledge? -- mitchy

Re: [Zope] i18n: how to use it in zpt's without CMF&Plone? [Solved]

Hi Bernd, my problem was that I had installed PlacelessTranslationService after TranslationService. This is a problem since only one service can be installed. After removing it everything works according to http://www.zope.org/Members/efge/TranslationService I think this should be noted somewhere in the docs. -- Elena

Back button (off topic?)
by Michael Long 18 Sep '03

18 Sep '03

Hi, I am attempting to implement a back button in my zpt page. The following code works in IE but not Mozilla Firebird. When I click the button in Firebird nothing happens. I have checked the options in Firebird and javascipt is enabled. Does anyone know what could be causing this behavior? <input type="button" value="Back" onClick="history.go(-1);return true;"> Thanks, Mike

HOWOT: DirectoryStorage and Zope under Debian
by J C Lawrence 18 Sep '03

18 Sep '03

I've recently become a fan of DirectoryStorage: http://dirstorage.sourceforge.net/ and spent some time getting it happy under Debian's Zope package. In case others may want to do the same, here's how I got it working: 0) The assumption is that all the following are performed as root. 1) Install Zope in the normal Debian fashion. (# apt-get install zope). Note: I didn't install the 'zopectl' package. 2) Install DirectoryStorage as per the install instructions in /usr/lib/zope/lib/python, and copy the product directory over to the appropriate Zope instance. For me that was /var/lib/zope/instance/default/Products. 3) Follow the rest of the DirectoryStorage installation instructions. 4) custom_zodb.py should look something like: --<cut>-- import os,sys from DirectoryStorage.Full import Full as S from DirectoryStorage.Filesystem import Filesystem # Change this to point to your database directory fs = Filesystem('/var/lib/zope/instance/default/var/Data_fs_dir') Storage = S(fs) --<cut>-- Your path for the value of `fs` may vary if you're using a non-default instance. 5) Edit /etc/zope/zopectlrc and comment out the ZOPEOPTS line which specifies the zope user as shown in the following excerpt: --<cut>-- ZOPEOPTS="${ZOPEOPTS} --pid ${zope_pidfile}" # ZOPEOPTS="${ZOPEOPTS} -u zope" ZOPEOPTS="${ZOPEOPTS} -l ${zope_logfile}" ZOPEOPTS="${ZOPEOPTS} -z ${ZOPE_HOME}" --<cut>-- 6) Edit /etc/init.d/zope and edit the first case such that it reads: --<cut>-- start|stop|restart|force-reload) su - zope -c "$ZOPECTL $ZOPECTLOPTS $1 $ZOPEOPTS" ;; --<cut>-- FYI the original form of the line was: $ZOPECTL $ZOPECTLOPTS $1 $ZOPEOPTS 7) Do the following (edit as appropriate for your instance) to get the permissions right on the log and pid files, the instance specific Products, and the DirectoryStorage hierarchy you just created: # chown zope.zope /var/run/zope/default /var/run/zope/default/* # chown zope.zope /var/log/zope/default /var/run/zope/default/* # cd /var/lib/zope/instance/default # find . | xargs chown zope.zope 8) Start zope: # /etc/init.d/zope/start You should see many new files being created under your DirectoryStorage hierarchy and after a short delay while a default ZODB is instantiated, Zope should be running atop the new storage layer. 9) Follow the rest of the DirectoryStorage installation and operation instructions. Enjoy. -- J C Lawrence ---------(*) Satan, oscillate my metallic sonatas. claw(a)kanga.nu He lived as a devil, eh? http://www.kanga.nu/~claw/ Evil is a name of a foeman, as I live.

Can't get past the login screen...
by Ron 17 Sep '03

17 Sep '03

I've installed Zope on a RH system, I get the password dialog (for 3 gerr... days) but nothing else, the system continues to ask for a correct username/password. I have run the zpasswd.py script with "access" and "inituser" in both the /usr/lib/zope2.7 and it's "bin" directory, used clear passwords, and the default, changed permissions (on everything) to "zope" (Zope runs as user zope on my system). Restarted after each password change, run it with Galeon, Mozilla, Konqueror... From a remote machine and a local, searched the mailing list (Yahoo lists SUCKS, btw), Google, and the Zope site and read the logs. The best message I have received from zope comes from Konqueror "Authentication Failed!" Can anyone suggest how I might get Zope working? Thank you. (This is SO FRUSTRATING!!!) -Ron Details: RH 7.2, Zope: 2.7.0-b2, Python2-2.2.3-1, Zope and Python compiled and installed from rpm's.

Internal representation of permissions acquisition
by nwingfield＠che-llp.com 17 Sep '03

17 Sep '03

When looking into Zope's internal representation of permissions and so forth, I found something strange... Suppose, for example, I have checked 'Anonymous' for 'View' on a particular object, a new attribute called ' _View_Permission' is created in my object. Here's the strange thing: If I leave 'Acquire' checked, _View_Permission = ['Anonymous'] If I uncheck 'Acquire', _View_Permission = ('Anonymous',) Please confirm or deny my hypothesis that the sequence data type assigned to a particular permission is the only way that Zope determines whether permissions should be acquired or not. It appears to me that the use of a list is Zope's internal representation of a checked 'Acquire Permissions' box, and the use of a tuple represents an unchecked 'Acquire Permissions' box.
