Module Sequel::Plugins::InputTransformer
In: lib/sequel/plugins/input_transformer.rb

InputTransformer is a plugin that allows generic transformations of input values in model column setters. Example: 

  Album.plugin :input_transformer
  Album.add_input_transformer(:reverser){|v| v.is_a?(String) ? v.reverse : v}
  album = Album.new(name: 'foo')
  album.name # => 'oof'

You can specifically set some columns to skip some input input transformers: 

  Album.skip_input_transformer(:reverser, :foo)
  Album.new(foo: 'bar').foo # => 'bar'

Usage: 

  # Make all model subclass instances support input transformers (called before loading subclasses)
  Sequel::Model.plugin :input_transformer

  # Make the Album class support input transformers
  Album.plugin :input_transformer
