Question

having a problem with a heroku upload. Quite new to RoR so please excuse the beginners question.

I’m following the Ruby on Rails Tutorial (http://ruby.railstutorial.org), and after the scaffolding, I type heroku rake db:migrate and get the following error:

rake aborted! 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)

First time around, no problem, but this time I’m getting this error. Any ideas?

Answer 1

Not quite the answer Simone, but after more digging, the answer finally came up. I needed to do the following:

In the gemfile, I needed to change gem ‘sqlite3’ to:

group :development, :test do   gem 'sqlite3' end

group :production do   gem 'pg' end

and then I needed to heroku create –stack cedar.

Thanks for your help everyone regardless, and I hope this helps someone in the future.
