Overview

Adapter for Sequel …

… is a Sequel::Plugin.

To make it overall available:

class Sequel::Model
  is :not_naughty
end

Options:

To turn off before_validate and after_validate hooks:

class User < Sequel::Model
  is :not_naughty, :without => :hooks
end

To turn off raised Exceptions if validation before save fails:

class User < Sequel::Model
  # save on invalid users will return false
  is :not_naughty, :without => :exceptions
end

To combine those:

class User < Sequel::Model
  is :not_naughty, :without => [:exceptions, :hooks]
end

API compatibility:

The validates_length_of method does only one check per attribute. If you want to check minimum and maximum length with different error messages you need to write 2 validations:

validates_length_of :name, :minimum => 4
validates_length_of :name, :maximum => 12

Except the example above the Plugin should be 100% API compatible.
