Form Variable location and persistence!
by ricardo＠cnbe.mar.org.uk 23 Aug '01

Hi, I have a input variable 'username' in a form. This form call a DTML method that call a stored procedure to check for user autorization. When the user login it will be send to a main page with a navigation frame and a main frame. The main frame will reder all modules that this user will be able to use. My problem is that I have to pass the 'username' entered in the first form to this modules selection DTML method but Zope can not find the username parameter. I have tried the examples in Chap 7 of The Zope Book but it doesn't work. Does anyone knows how to do that. How can I create persistent variable in Zope? If I need to use cookies how can I do that in Zope? TIA Regards, Ricardo

POST works with tcpwatch port, but not Zope 8080 port
by Irene Barg 23 Aug '01

23 Aug '01

Hello, Zope Version: Zope 2.3.3 (binary release, python 1.5.2, linux2-x86) Python Version: 1.5.2 (#10, Dec 6 1999, 12:16:27) [GCC 2.7.2.3] System Platform: linux2 This is a follow-up on an earlier post "IE problems with Zope Solaris binary", but please read on. I have a family database that users can browse with no problem. Created a role called 'dbupdate', then disabled all 'Acquire permissions settings' for the Update folder, then enabled the following for the 'dbupdate' role: Access contents information Open/Close Database Connection(s) Query Vocabulary Search ZCatalog Use Database Methods Use Factories Use mailhost services View View History View management screens Created 2-3 users in the Update folder and gave them 'dbupdate' roles. These users can login to the Update folder, GET a family record, edit it, but when it comes time to 'Submit' their updates (which does a POST), they get a message that simply says, "The Page cannot be displayed. The page you are looking for is currently unavailable. The Web site might be experienceing technical difficulties, or you may need to adjust your browser." Now, this particular Zope site was originally on a Solaris system, and I had posted this same problem under the subject "IE Problems with Zope Solaris binary." However, moving the Zope site to a Linux box appeared to fix things. At least I cannot re-create the problem in this building. The problem only shows up when users outside (literally out of state) who come in from their Internet Service providers like AOL. Dieter Maurer and Tino Wildenhain had suggested I use 'tcpwatch' to debug this problem. On the Solaris installation, this didn't work because the ZServer simply dumped core, died, and tcpwatch die along with it. However, on the Linux setup, I started tcpwatch: python tcpwatch.py 8086 jesse.as.arizona.edu 8080 I ask one of my out of State users to try an Update using the 8086 address and behold, she can do Updates and the POST doesn't fail! What may be a clue here, is that if you look at the Z2.log, it shows her coming in on the 'jesse' address. I guess this is because tcpwatch is acting as a proxy. Now the million dollar question is: Was the success coming via the tcpwatch port a fluke? Or, could it be related to the permissions I gave the 'dbupdate' role? Or, could it be something related to 'file system' permissions in the /usr/local/zope tree? /usr/local/var looks like this: jesse:/usr/local/zope> ls -l var total 7568 -rw------- 1 nobody barg 574368 Aug 22 09:02 Data.fs -rw-r--r-- 1 nobody barg 75448 Jan 22 2001 Data.fs.in -rw-r--r-- 1 nobody barg 160858 Aug 9 14:51 Data.fs.index -rw-r--r-- 1 nobody barg 5 Aug 20 12:29 Data.fs.lock -rw-r--r-- 1 nobody barg 26176 Aug 22 09:02 Data.fs.tmp -rw-r--r-- 1 nobody barg 854346 Aug 22 13:44 Z2.log -rw-r--r-- 1 nobody barg 9 Aug 20 12:29 Z2.pid -rw-r--r-- 1 nobody barg 725 Aug 20 12:29 Zope.log -rw-r--r-- 1 nobody barg 4 Aug 20 12:29 pcgi.pid srwxrwxrwx 1 root root 0 Aug 20 12:29 pcgi.soc= -rw-r--r-- 1 nobody barg 4 Aug 20 12:29 zProcessManager.pid And in the top level of the Zope tree: jesse:/usr/local/zope> ls -l total 132 drwxrwxr-x 2 barg barg 4096 Aug 9 10:49 Extensions/ -rw-r--r-- 1 barg barg 3479 Mar 9 1999 LICENSE.txt -rw-r--r-- 1 barg barg 987 Apr 29 1999 README.txt drwxrwxr-x 4 barg barg 4096 Aug 9 09:41 ZServer/ -rwxr-xr-x 1 barg barg 483 Aug 9 09:41 Zope.cgi* drwxrwxr-x 2 barg barg 4096 Jun 20 12:34 bin/ drwxrwxr-x 3 barg barg 4096 Jun 20 12:34 doc/ drwxrwxr-x 2 barg barg 4096 Aug 19 18:15 import/ drwxrwxr-x 2 barg barg 4096 Aug 9 09:41 inst/ -rwxr-xr-x 1 barg barg 225 Jul 23 1999 install* drwxrwxr-x 4 barg barg 4096 Jun 20 12:34 lib/ drwxrwxr-x 7 barg barg 4096 Aug 9 09:41 pcgi/ -rwx--x--x 1 barg barg 194 Aug 20 12:29 start* -rwx--x--x 1 barg barg 166 Aug 9 15:04 start.debug* -rwx--x--x 1 barg barg 54 Aug 9 09:41 stop* drwxrwxr-x 2 barg barg 4096 Aug 9 09:41 utilities/ drwxrwxr-x 2 nobody barg 4096 Aug 20 12:29 var/ -rw-r--r-- 1 barg barg 25418 Mar 8 14:41 z2.py -rw-r--r-- 1 barg barg 15777 Aug 9 09:41 z2.pyc -rw-r--r-- 1 barg barg 9546 Dec 7 2000 zpasswd.py -rw-r--r-- 1 barg barg 6424 Aug 9 09:41 zpasswd.pyc I apologize for this long post, but, this is REALLY bugging me.

Re: [Zope] Images from database into html
by Sven Syld 23 Aug '01

> > I have gained access to a employees' database which among > > other stuff contains employees' photos (that is, in binary form). > > I'm trying to display employees with their names and photos etc. > > HTML page looks like this: > > <dtml-in sql_employees> > > <dtml-var first_name> <dtml-var last_name> > > <img src="his_or_her_photo"> (which is DTML method) > But it is not called! Actually it is called. Even if object is fetched this way. I think problem was that when it was called it was not under namespace of <dtml-in sql_employees>. But I got it working now (see at the end of this mail). > What about: > <dtml-var photo> Thats no good since it just prints the binary contents in the HTML page. My photos are as files, not as a filenames, in database. (I looked around a little and read that this is not good practice, but it would be very hard for me to do something about it). Ok, here is what I did. Database has these fields: person_id, first_name, last_name, photo. <dtml-in sql_employees> <dtml-var first_name> <dtml-var last_name> <img src="persons_photo?person_id=<dtml-var person_id>"> </dtml-in> persons_photo is DTML method: <dtml-in sql_photo><dtml-var photo></dtml-in> (no linefeeds or spaces between since it would mess up the file and would be interpreted incorrectly) sql_photo is SQL method, which takes attribute: person_id. SELECT photo FROM employees WHERE person_id=<dtml-var person_id> Sven Syld
