Moving from Sqlite3 to PostgreSQL Rails - ruby-on-rails

Question

I'm trying to move my database to a PostgreSQL because I'm putting it up on Heroku.
Followed Railscast #342. Installed PostgreSLQ with its dependencies on my Ubuntu machine. When I installed it I think a user was created. I used this user in my database.yml. It looks like this:
production:
adapter: postgresql
encoding: unicode
database: dlrvbtApp1_production
pool: 5
username: jdartland
password:
development:
adapter: postgresql
encoding: unicode
database: dlrvbtApp1_development
pool: 5
username: jdartland
password:
test:
adapter: postgresql
encoding: unicode
database: dlrvbtApp1_test
pool: 5
username: jdartland
password:
Installed pg gem and the taps gem.
Ran a Bundle install, created the databases with rake db:create:all
Started the taps senatra server with taps server sqlite://db/development.sqlite3 jdartland secure
The server started. And tried to pull the SQL to my new development db through this command.
taps pull postgres://jdartland#localhost/dlrvbtApp1_development http://jdartland:secret#localhost:5000
I then get this error:
Failed to connect to database:
Sequel::DatabaseConnectionError -> PG::ConnectionBad: fe_sendauth: no password supplied
I have tried and tried, created new databases, canhing the .yml, pg_config and so on but I can't get it to work.
This is my first time working with PostgreSQL and Heroku, please give me a hand! :)

Answer 1

Change the user on production to localhost and leave the password blank.
production:
adapter: postgresql
encoding: unicode
database: dlrvbtApp1_production
pool: 5
username: localhost
password:

Answer 2

If you're moving your database to Heroku, the whole thing is just a case of connecting your DB to Heroku's PG one, and migrating the data.
Did you receive database details from Heroku?
They basically use Amazon to serve their DB's, and you'll get some credentials to put into your yml file for it. Here is an example of one of our live Heroku apps:
production:
adapter: postgresql
database: ********
pool: 5
username: ****************
password: ****************
port: 5432
host: ec2-54-228-234-250.eu-west-1.compute.amazonaws.com
Ways To Migrate To PostgreSQL (Heroku)
If you're looking to migrate your data from SQLite3 to PostgreSQL, I found a really good tutorial on how to do this here. Only problem is that it's not for SQLite lol

Answer 3

If you're trying to pull down your database from Heroku into a local postgres database, use pg:pull or pgbackups:
https://devcenter.heroku.com/articles/heroku-postgresql#pg-push-and-pg-pull
https://devcenter.heroku.com/articles/heroku-postgres-import-export
You should also look into using foreman and a .env file to setup your DATABASE_URL similar to how it's ran on Heroku, for dev/prod parity:

Answer 4

Got It working by following another post here on stack. Simply went up one directory, installed taps Gem install Taps. Uninstalled Rack gem gem uninstall rack 4 then Reinstalled it gem install rack --version 1.0.1. Did not do this in my progect directory, just simply in RVM. Then Pulled the database from the same directory. (not from my project directory).
Here is the Whole tread: taps migration failing from sqlite to postgres rails4, ruby 1.9.3
Hope it helps someone with the same problem.
Now just one thing left, Push it to heroku..... We'll see how that goes...hehe
Thanks for all help!
