 With the :truncation strategy you can also pass in options, for example:
 <pre>
-  DatabaseCleaner.strategy = :truncation, {:only => %[widigets dogs some_other_table]}
+  DatabaseCleaner.strategy = :truncation, {:only => %w[widgets dogs some_other_table]}
 </pre>
 
 <pre>
-  DatabaseCleaner.strategy = :truncation, {:except => %[widigets]}
+  DatabaseCleaner.strategy = :truncation, {:except => %w[widgets]}
 </pre>
 
 (I should point out the truncation strategy will never truncate your schema_migrations table.)
