RoR application deployment

Question

I am running "heroku run rake db:migrate" after I have deployed my app to heroku and I get this:

$>>heroku run rake db:migrate

Running rake db:migrate attached to terminal... up, run.1

Please install the postgresql adapter: `gem install activerecord-postgresql-adapter` (pg is not part of the bundle. Add it to Gemfile.)

Tasks: TOP => db:migrate => db:load_config
(See full trace by running task with --trace)

I try installing the gem mentioned but nothing happens. I am using rails3 an ruby 1.9.3, and my database.yml file contains:

# SQLite version 3.x
#   gem install sqlite3
#
#   Ensure the SQLite 3 gem is defined in your Gemfile
#   gem 'sqlite3'
development:
  adapter: sqlite3
  database: db/development.sqlite3
  pool: 5
  timeout: 5000

# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
  adapter: sqlite3
  database: db/test.sqlite3
  pool: 5
  timeout: 5000

production:
  adapter: sqlite3
  database: db/production.sqlite3
  pool: 5
  timeout: 5000

How can I fix this error?

running $>>sudo gem install pg -v '0.13.2'

Are you trying to use postgresql or sqlite3? – Eric Sites Mar 13 '12 at 19:46 — Eric Sites, Mar 13 '12 at 19:46

Your database.yml is setup to use sqlite3.

If you want to use postgresql you need to install postgres on your computer first.

For Linux:

sudo apt-get install postgresql

For Max OS X:

brew install postgresql

Make you have homebrew installed first.

heroku autogenerates database.yml on the deploy. Reads like: it doesn't matter what you put in your database.yml, which to me is nice, as I can include it in git without worrying about production db passwords.

Then install the pg gem by putting this in your Gemfile:

gem 'pg', :require => 'pg'

if you are using an older version of Rails use the gem install method.

Eric, Heroku always uses Postgres, no matter what you put in `database.yml`. But unless you are rolling your own SQL, there is no harm in running SQLite locally and Postgres on Heroku. The OP's original problem was related to Heroku deployment; now he is running into another problem installing Postgres locally, which is different from what the original question was about. – Alex D Mar 13 '12 at 19:57

Try adding the 'pg' gem to your Gemfile (and then bundle install).

how do I configure it to use postgersql? – Test Test Mar 13 '12 at 19:45

@TestTest, if you just want to get your app working as quickly as possible, you can always `bundle install` *on a machine which has a working install of Postgres*. It's better to have it running on your development machine too, but that is a different problem from what you originally asked for help with. OR, you can hack `Gemfile.lock` by hand -- I've done this before when developing on Windows and deploying to Heroku, because some gems I needed to use couldn't be installed on Windows. – Alex D Mar 13 '12 at 20:01
