ruby on rails - Trying to switch from SQLite to PostgreSQL -


i using sqlite in development , test, , postgresql in production on heroku. replace sqlite postgresql. programming in cloud9 environment (rails 4). have no data potentially lose.

what did do:

first, edited database.yml:

default: &default       adapter: postgresql       encoding: unicode       pool: 5 development:   <<: *default   database: app_development test:   <<: *default   database: app_test production:   <<: *default   database: app_production

then:

  • in gemfile moved gem 'pg' production environment environments , removed gem 'sqlite3'
  • i ran bundle install.
  • i ran sudo service postgresql start
  • i ran sudo sudo -u postgres psql
  • and entered create database "app_development";
  • entered \q

update: added following additional steps:

  • i created new user in psql create user my_username superuser password 'my_password';
  • in database.yml added username , password
  • in database.yml added host: myurl.c9.io
  • i entered in psql: grant on database app_development my_username

running sudo sudo -u postgres psql , \list produces:

      name          |  owner   | encoding  | collate | ctype |   access privileges     postgres           | postgres | sql_ascii | c       | c     |   template0          | postgres | sql_ascii | c       | c     | =c/postgres          +                     |          |           |         |       | postgres=ctc/postgres  template1          | postgres | sql_ascii | c       | c     | =c/postgres          +                     |          |           |         |       | postgres=ctc/postgres  app_development    | postgres | sql_ascii | c       | c     |

i don't see username here owner of app_development...

error: running rake db:migrate times out, stating pg::connectionbad: not connect server: connection timed out server running on host "myurl.c9.io" (ip address) , accepting tcp/ip connections on port 5432?.

why might connection postgresql failing?

replace content of database.yml file to:

default: &default   adapter: postgresql   host: localhost   username: yourusername   password: yourpassword   timeout: 5000   port: 5432 development:   <<: *default   database: app_development test:   <<: *default   database: app_test production:   <<: *default   database: app_production

because use heroku can leave production section is

the normal openidconnect server works like: you go a.com/secure-resource you 302 server your browser handles , sends identity server you login there it sends a.com via post you logged in on a.com , a.com/secure-resource on browser. however have scenario i'm trying solve need help. the user logged in on idserver the user logged in on a.com the user not logged in on b.com we need send ajax call web server b.com (from domain a.com ) b.com configured use openidconnect. but because request b.com via ajax, user cannot redirected idserver.
