DESCRIPTION:

DataMapper plugin that helps you manipulate an existing database.
It creates mappings between existing columns and model's properties.

SYNOPSIS:

require 'dm-core'

# setup first, or dm-mapping can't determine which adapter it should load up
DataMapper.setup :default, 'sqlite3:db/development.sqlite3'

require 'dm-mapping'

class User
  include DataMapper::Resource
  # maping all
  mapping /.*/

  # mapping for ended with _at, and started with salt_
  mapping /_at$/, /^salt_/

  # mapping id and email
  mapping :id, :email

  # mapping all fields with type String, and id
  mapping String, :id

  # mapping login, and all fields with type Integer
  mapping :login, Integer
end

DataMapper.repository.adapter.storages
# => ['users']

User.fields
# => [['id',          Integer,  {:serial => true}],
      ['email',       String,   {:default => '[email protected]'}],
      ['created_at',  DateTime, {}],
      ['salt_first',  String,   {}],
      ['salt_second', String,   {}]]

DataMapper.repository.adapter.fields('users')
# => [['id',          Integer,  {:serial => true}],
      ['email',       String,   {:default => '[email protected]'}],
      ['created_at',  DateTime, {}],
      ['salt_first',  String,   {}],
      ['salt_second', String,   {}]]
