Jak moge podlaczyc sie do istniejecej bazy
Skonfigurowalem polaczenie do bazy w config/databases.yml
Zrobilem rake db:schema:dump ( uzyskalem poprawny dump struktury)
Stworzylem model recznie odpowiadajacy tabeli
Jednak przy uruchomieniu z konsoli
Model.all wywala mi blad
Mozna prosic o rady co moze byc powodem
Mper.all
(136.7ms) SET SCHEMA mcs_dev

Przeylam fragment database.yml
development:
adapter: ibm_db
username: db2inst1
password: haslo
database: mcs_dev
schema: mcs_dev
host: localhost
port: 50000
#account: my_account
#app_user: my_app_user
#application: my_application
#workstation: my_workstation
#security: SSL
#timeout: 10
#authentication: SERVER
#parameterized: false
Moglbys sprobowac czy to dziala dla najprostszego modelu? Wygeneruj np. model z 1 kolumna i sprawdz czy bedziesz mial ten sam blad.
Bardzo mozliwe, ze adapter do DB2 cos psuje, choc z drugiej strony nie widac go w backtrace, ktory podales.
To mnie wlasnie zastanawia
ale z drugiej strony po wydaniu rake db:schema:dump
pobral mi caly schemat bazy do pliku schema.rb
nie mam pojecia o co moze chodzic.
