streaming data through zope from an external method.
by Anthony Baxter 10 Mar '99

10 Mar '99

I've got an external method that is generating a (possibly quite large) audio file and sending it back. Right now, I'm generating this in memory in a big string, then returning it to zope. I'd _like_ to be able to just have the external method send the data straight through (maybe in chunks) without having to read it all into memory. Is this possible with zope at all? Anthony

Apache Authorization

Hi, I cannot go to management screen of Zope, probably due to some problem with Apache. http://www.sol.cz/cgi-bin/Zope.cgi, if someone would care to look at it. Thanks! -- Milos Prudek

ZPyGreSQL Database Connection Problem
by William Whitehead 10 Mar '99

10 Mar '99

I just installed the updated version of PostgreSQL 6.4.2 on Linux 2.2.2. I was able to compile and add the ZPyGreSQL Product to my Zope installation. I want to create a Database connection. When I go to create a new one, it asks for the Id, Title, and Database Connection String. What do I put into the Database Connection String? I tried the database I want to use, but it gives Invalid connection String: baseball Is it a rights issue with PostgreSQL or something else? What is it expecting the database connection string field anyway? Thanks for your help!

Another "no such file" failure...
by Mike Meyer 10 Mar '99

10 Mar '99

I'm trying to get zope working to study it, but keep stumbling over the "(102) failure during connect" error - with the "No such file or directory" addendum. The underlying OS is FreeBSD 3.1. I want to run it on an Apache web server (at least for now), with the server doing the authentication. That all appears to be working properly - after all, I'm getting errors from pcgi, now, right? The var directory is writable by nobody. In fact, the entire source tree is owned by nobody, which is the user that the Apache httpd is running as. However, I get log file entries from pcgi, even after deleting the pcgi.log file. I initially tried copying the Zope.cgi file to cgi-bin, but noticed that some (unspecified) setting in Zope.cgi might need to change because of that, so I added a second scriptalias to the Apache httpd.conf pointing at the source directory, set the protections on it, and tried to load <URL: http://localhost/Zope-bin/Zope.cgi/manage >. No change - the log file records the same error message. The pcgifile.py test reports error attempting: 'from cgi_module_publisher import publish_module' This doesn't appear to exist in the distribution - and I recalled something about that being a holdover from bobo, so I removed that test from the script, and ran it again. The modified version runs cleans. Was I wrong about cgi_module_publisher? Should it be finding that? If not, then what's the next thing to look at? FWIW, here's the entry from httpd.conf section for Zope: SriptAlias /Zope-bin/ "/home/mwm/external-src/Zope-1.10.2-src/" <Directory "/home/mwm/external-src/Zope-1.10.2-src/"> AllowOverride None Options None FollowSymLinks Auth_PGhost sql Auth_PGport 5432 Auth_PGdatabase web Auth_PGpwd_table users Auth_PGuid_field name Auth_PGpwd_field password Auth_PG_encrypted off AuthName "Zope" AuthType basic require valid-user </Directory> And here's Zope.cgi: #!/home/mwm/external-src/Zope-1.10.2-src/pcgi/pcgi-wrapper PCGI_NAME=Main PCGI_MODULE_PATH=/home/mwm/external-src/Zope-1.10.2-src/lib/python/Main.py PCGI_PUBLISHER=/home/mwm/external-src/Zope-1.10.2-src/pcgi/pcgi_publisher.py PCGI_EXE=/usr/local/bin/python PCGI_SOCKET_FILE=/home/mwm/external-src/Zope-1.10.2-src/var/pcgi.soc PCGI_PID_FILE=/home/mwm/external-src/Zope-1.10.2-src/var/pcgi.pid PCGI_ERROR_LOG=/home/mwm/external-src/Zope-1.10.2-src/var/pcgi.log PCGI_DISPLAY_ERRORS=1 BOBO_REALM=Zope BOBO_DEBUG_MODE=1 INSTANCE_HOME=/home/mwm/external-src/Zope-1.10.2-src Thanx, <mike

Re: [Zope] Access to DTML Document properties

Thanks for your help, Pavlos. I found another way. Instead of writing:  I wrote this, and it worked fine:  I found a way, but I don't understand why the first syntax worked fine with Folders and fails with DTML Documents. If anyone would like to clarify the semantic difference between _['sub-document'] and _.getitem('sub-document'), I would be even happier. By the way, Pavlo's site http://www.gaaros.com:9673/ is useful! []s Luciano

I understand the difference between DTML Methods and DTML Documents. The very reason I chose to do it with DTML Documents was to be able to store some special fields, such as 'author' in my example, along with the document. I cannot do that with DTML Methods, as they do not have properties. In Zope 1.0.9 I used folders but I was running into problems with relative links. It seemed natural to switch from my previous folders to the new DTML Documents. I still do not know to reference the properties of a DTML Document 'A' from within a document or method 'B' in located in the same folder as 'A'. Thanks for any help. []s Luciano

Hello folks, Correct me if I'm wrong, but ZopeHTTPServer is Medusa, correct? Does Medusa/ZopeHTTPServer support SSL? Thanks! -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Tom Jenkins DevIS (http://www.devis.com) I suggested holding a "Python Object Oriented Programming Seminar", but the acronym was unpopular.

tree doesn't work 4me linux amd win32

I just installed on a windows 95 box and on a linux 2.0.something but I can't get anything with tree working (other stuff seems ok). Hadars' second sample app doesn't work for me (the tree part produces no output). Even the minimal   doesn't produce output (tried this with the second Habar example after creating the "sub-folders"). I get the same behaviour on windows as linux. I must be doing something wrong. Clues please ? I had the same problem, but only with Zope 1.10.2. I noticed that DTML documents (the default to be created) won't work with the tree tag. If you create a DTML Method (like the old DTML from Zope 1.9) then they work as expected. I don't have a clue as to why this works like this. Maybe its the proerties of the DTML Documents that are acting folderish and tree doesn't know what to do?

Q: Setting/Creating variables
by James A. Hillyerd 10 Mar '99

10 Mar '99

I have been playing around with Zope/ZPublisher/DocumentTemplate and have been extremely pleased with the ease of development, as well as the power of the Python language. Sometimes I have found myself wanting to save the results of an expression in my DTML code, for use later in the same page (or even an embedded DTML object). The only thing I have used that is similar to DTML is ColdFusion, which has a CFSET tag, ie: <cfset myvar = "test"> or <cfset total = subtotal * tax> In reading the docs, it looked like I might be able to do something along the lines of  but this didn't seem to work, and it's not very elegant either. Am I missing something? None of the howtos or tutorials seem to cover this. A  /  would be really spiffy. =) Please make sure you CC me if you respond to this message, as I had to unsubscribe due to the overwhelming amount of traffic. Thanks! -james [] James A.
