Hello People,
I tried this in pry[2] pry(main)> require 'mysql2'
=> true
[3] pry(main)> require 'active_record'
=> true
[4] pry(main)> ActiveRecord::Base.establish_connection(:adapter => 'mysql', :database => 'db_name', :username => 'root', :password => 'root', :host => 'localhost')
LoadError: Could not load 'active_record/connection_adapters/mysql_adapter'. Make sure that the adapter in config/database.yml is valid. If you use an adapter other than 'mysql2', 'postgresql' or 'sqlite3' add the necessary adapter gem to the Gemfile.
Why do I need a Gemfile for trying active record in irb / pry. Its strange. Is active record so coupled with rails that it cannot be used outside?
