Обсуждение: Python + PostgreSQL
Hi All !
I have installed postgresql-python-7.0.2-2.i386.rpm in a RedHat 6.2 box.
Where can I find documentation for this module ? I'm trying to connect to a
server but the python says 'no password supplied'
import pg
dg = pg.connect("template1", "localhost", 5432)

I used the Postgresql python package to write a program. I couldn't find
any documentation either. Examples come in the RedHat package.
I used qit like this:
from pg import DB
cnx = DB("database-name")
cnx.query("""CREATE TABLE ...""")
You can see the full application at http://deodas.sourceforge.net/. Thqe
parts in the the file DEODAS/deodas/src/deodas_mod.py under CVS web.

Hi Karl !
Yes, this works for localhost and for servers that don't need user
authentication, but I need to connect to a remote server using an specific
username and password... Anyone can help ?

Look at the actual distribution either in the PostgreSQL tree or download the package from http://www.druid.net/pygresql/ and look at the README file. > I used qit like this: > from pg import DB > cnx = DB("database-name") > cnx.query("""CREATE TABLE ...""") The reccommended way is now; import pg cnx = pg.DB("database-name") The reason for this is to make pg.error and possibly other things available. -- D'Arcy J.M.

If the server requires a password then you need to supply one here. If
you don't need a password (i.e. "psql template1" works) then try this.
import pg
dg = pg.DB("template1")
Note DB is preferred over connect but the main change is not to use localhost
to connect. The default is to use a Unix socket rather than TCP/IP to
localhost and PostgreSQL treats that differently. If localhost was just
used here for illustrative purposes and in fact you are connecting over
TCP/IP to another machine then look at pg_hba.conf to adjust permissions
or add a password to the connection call.

Hi again !
How must I add the password to the call , maybe
dg = pg.connect("template1", "10.0.0.1", 5432,"username", "password") ?
and where could I find documentation for the different functions supplied
in the package ?

connect(dbname, host, port, opt, tty, user, passwd)
Set any unused parameters to None.

In the README that comes with the distribution.

Interesting. Unfortunately, their home page doesn't say anything about this. Have a more direct URL? -- Bob Kline mailto:bkline@rksystems.com http://www.rksystems.com

You might give the first part of that, http://www.ibooks.com/SiteSrvr/, a try and see what happens. Alternately, look for the penguin on the right hand side of the page, and look at the fine print in its vicinity. Cheers, -dlj.

Tried your suggestions, and have come to the conclusion that they decided to withdraw the offer. -- Bob Kline mailto:bkline@rksystems.com http://www.rksystems.com
