Oracle & Ruby on Rails

Rails
1

I’ve a remote database create using Oracle. This database use schemas.
I tried to connect to it using Ruby On Rails,with this file Database.yml
:

development:
adapter: oci
host: liber
database: ENERGIA
username: user
password: pass

test:
adapter: oci
host: liber
database: ENERGIA
username: user
password: pass

production:
adapter: oci
host: liber
database: ENERGIA
username: user
password: pass

Where “ENERGIA” is a schema’s name.
I want to create a model for a table named “Platts” that is into
ENERGIA.
I use this command: ruby script/generate scaffold platt action_name
But everytime Rails Tell me that this Table doesn’t exist!
Can someone tell me what’s the problem?

You’ll also want to triple-check that your TNS_ADMIN environment
variable is correct.

The oracle adapter doesn’t use the database parameter.
You can connect passing a tnsnames.ora defined name in the host
parameter. e.g. If you have oracle client installed and this:

ORCL.WORLD =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = hostname)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = ORCL)
)
)

inside you tnsnames.ora then you can connect using

development:
adapter: oci
host: ORCL.WORLD
username: scott
password: tiger

If you don’t have a tnsnames.ora you can still connect passing the
hostname plus the sid to the host parameter e.g.:

development:
adapter: oci
host: hostname/ORCL
username: scott
password: tiger

Then the schema would be the default one for the scott user (probably
‘SCOTT’). in your case you probably need to connect with the ENERGIA
user.
