Plugins by Bob Silva

• Acts As Threaded

  Great for creating threaded forums and other tree structures where performance is a concern. The nested_set model is insert/update heavy but the whole tree can be retrieved in order from the database with a single query.

• Enhanced ActiveRecord Errors

  Allows full customization of the errors generated using ActiveRecords error_messages_for method

• Validates Numericality Of

  Extends the validates_numericality_of validation by adding :gt, :gte:, :lt, :lte, :eq, :even, :odd conditions

• Query Analyzer

  Provides query analysis using the MySQL query execution plan. Each SQL select query will be 'EXPLAIN'ed and added to the log files right below the original query.
