ActiveRecord Claims No Adaptor Specified <p>When I try to run the following, I get an error back from ActiveRecord stating that the connector hasn't been found.</p> <pre><code>require 'activerecord' ActiveRecord::Base.establish_connection( :adaptor =&gt; "sqlite3", :database =&gt; "db.sqlite3" ) </code></pre> <p>Error Message:</p> <pre><code>&gt;&gt; ActiveRecord::Base.establish_connection("adaptor" =&gt; "sqlite3-ruby") ActiveRecord::AdapterNotSpecified: database configuration does not specify adapter from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8/ gems/activerecord/2.2.2/lib/active_record/connection_adapters/abstract/ connection_specification.rb:64:in `establish_connection' </code></pre> <p>Is the ActiveRecord gem broken, or is the initial code incorrect?</p>
