Well, you’d get better help if you told us what you’d already tried and
what didn’t work (with error messages as applicable).

there is some details about my system ==>

=> I have MS Windows Xp on my desktop
=> I installed ruby 1.9.1-p378
=> I installed rail 2.3.5
=> I installed PostgreSql 8.4

Have you installed any of the gems for connecting Ruby with Postgres
(such as postgres or pg)? Without these gems, Ruby can’t talk to the
DB.

Thanks and Thanks and Thanks so much

Thanks to all
thank you my friend Marnen Laibow-Koser

I solved my problem with your advice and of course my god help :slight_smile:
I had problem on three things :

first => my pgadmin ;i mean i didn’t set my pgAdmin’s username in
database.Yml as user name

second => I have two version for ruby so errors comes out one after
another

third => I set the wrong gem install for postgreSql

another question ? =>

Can we have and use different DBMS install gem on one machine ?
for example : gem install sqlite-3 and gem install mysql and gem install
… and use one of them for each project i mean one project use MS SQL
SERVER and another one
use postgreSQL in the same time?

=^.^=…Your welcome… but… i’m a woman… XD… i’m not man heheh

Yes, just put the appropriate setting in database.yml. You can even
have different drivers between production and development on the same
app.

production:
adapter: postgresql
database: myportal
username: usr
password: pwd
host: myhost

development:
adapter: sqlite3
database: db/development.sqlite
timeout: 5000
charset: UTF8

test:
adapter: sqlite3
database: db/test.sqlite
timeout: 5000
charset: UTF8

oracle:
adapter: oracle
database: srv/instance
username: usr
password: pwd
encoding: utf8

This is my database.yml. I use sqlite for test and development and
postgres in production for my main db. I also need data from some tables
located in oracle.

Here is how you write model for table in oracle db:

class Ora_client < ActiveRecord::Base
establish_connection(:oracle)
set_table_name “klients_table”
end
