Hi, I spent a couple of hours trying to get Zope to work with postgres. There simply was not one good guide or howto available, all the rigth info was avaialble -- but on different mailinglists. Here is what I did, hope it helps someone else -- or perhaps someone will get a spark from this and write a decent howto. Atleast after this mail people will find the info from one place. Using: Zope Zope 2.3.2 Python 1.52 ExUserFolder 0-8-0 psycopg-0.99.6 postgresql-7.1.3 egenix-mx-base-2.0.2 1) Getting all the pieces together Postgresql - http://www.postgresql.org/ ExUserFolder - http://exuserfolder.sourceforge.net/ psycopg (Postgres database adapter ) - http://www.zope.org/Members/fog/psycopg egenix mx Extensions - http://www.lemburg.com/files/python/eGenix-mx-Extensions.html 2 ) Installing Postgres Downloaded source-distribution and unpacked it to my tmp. cd to the postgres directory. Read from the manual how to install. Here is it snipped in short form. ./configure gmake gmake install adduser postgres mkdir /usr/local/pgsql/data chown postgres /usr/local/pgsql/data su - postgres /usr/local/pgsql/bin/initdb -D /usr/local/pgsql/data /usr/local/pgsql/bin/postmaster -D /usr/local/pgsql/data >logfile 2>&1 & /usr/local/pgsql/bin/createdb test /usr/local/pgsql/bin/psql test After this make sure that the lib-files are in a place that Zope can find them! 3 ) Install egenix mx Extensions Downloaded source-distribution, since only that has the header-files we need while compiling psycopg. Unpack into temp. cd to the directory. python setup.py install 4) Installing psycopg Unpack to the temp. cd to the directory. Make sure you know where your egenix-sources are, postgres lib-files and postgres includes. Then give then in config. Example below. ./configure --with-mxdatetime-includes=../egenix-mx-base-2.0.2/mx/DateTime/mxDateTime/ --with-postgres-libraries=/usr/local/pgsql/lib --with-postgres-includes=/usr/local/pgsql/include make make install 5) Copying files to rigth places This part was frustrating and propably has had everyone wondering for some time. I found this thing to be helpful, tip was also found on different mailing lists. copy mxDateTime.so from: .../python1.5/site-packages/mx/DateTime/mxDateTime.so to: .../python1.5/site-packages/mxDateTime.so so that psycopgmodule.so can find it when zope is started up. And similarly make sure that the psycopgmodule is located in the psycopgmodule.so got placed in .../python1.5/site-packages/psycopgmodule.so 6) Installing exUserFolder Just unpack it and copy to zope/Products - where ever you have it. 7) Create database table for authentication Within the exUserFolder distribution comes a file pgAndreasScheme.sql.

From that we will use only one table for now.

This is just for testing purposes. su postgres psql template1 CREATE TABLE "passwd" ( "username" character varying(64) UNIQUE NOT NULL, "password" character varying(64) NOT NULL, "roles" character varying(255), Constraint "passwd_pkey" Primary Key ("username") ); \q You have created your table. 8) Restart zope 9) Go into management interface You should see Z psycopg Database connection in the list available for selection. If not, go to the control panel and product management and see what is the traceback on that product. Propably some of the modules is not found - which can be because you lib-files are somewhwere whwre they should not be ,-) Try to add Z psycopg Database connection. For connection string use: dbname = template1 user = postgres Ok. Everything should work. You can test it by clicking the test-tab in Z psycopg and trying following sql-query: select * from passwd; 10) Add exUserFolder Warning. Don't do this on the root folder! Select postgres authentication source. And select rest as you like. Click next. For authentication properties write: Table Name: passwd Username Column: username Password column: password Roles Column: roles Etc. Have fun. Hope this helps. -huima
