Rails 3 removes the deprecated SQLite 2 adapter. We strongly recommend that you upgrade to SQLite 3 or higher. However, if that's not possible due to the unexplainable reasons, then this plugin should do the job. Install ======= * Install the plugin : $ script/plugin install git://github.com/rails/sqlite2_adapter.git * Load the database adapter from your environment.rb Rails::Initializer.run do |config| ..... Rails::Initializer.default.add :initialize_sqlite2, :before => :initialize_database do require 'active_record/connection_adapters/sqlite2_adapter' end end That's it.
