Example of AccessibleSeedYaml::Table

require 'accessible_seed_yaml'

original_seed = File.read('numbers.yaml')

@table = AccessibleSeedYaml::Table.new(original_seed)

# Instance is providing data access interface.
@table.records
# => 
# [
#   #<AccessibleSeedYaml::Record:0x007f91552770c0
#    @original_seed="data1:\n  id: 1\n  name: \"one\"\n",
#    @seed_data_by_hash={"data1"=>{"id"=>1, "name"=>"one"}}>,
#   #<AccessibleSeedYaml::Record:0x007f915526c238
#    @original_seed="data2:\n  id: 2\n  name: \"two\"\n",
#    @seed_data_by_hash={"data2"=>{"id"=>2, "name"=>"two"}}>,
#   #<AccessibleSeedYaml::Record:0x007f91552662c0
#    @original_seed="data3:\n  id: 3\n  name: \"three\"",
#    @seed_data_by_hash={"data3"=>{"id"=>3, "name"=>"three"}}>
# ]

@table.records[0]
# => #<AccessibleSeedYaml::Record:0x007f9155725068
# @original_seed="data1:\n  id: 1\n  name: \"one\"\n",
# @seed_data_by_hash={"data1"=>{"id"=>1, "name"=>"one"}}>

# Instance is holding original seed.
@table.original_seed == original_seed
# => true

Example of AccessibleSeedYaml::Record

@record = @table.records[0]

@record
# => #<AccessibleSeedYaml::Record:0x007f9155725068
#     @original_seed="data1:\n  id: 1\n  name: \"one\"\n",
#     @seed_data_by_hash={"data1"=>{"id"=>1, "name"=>"one"}}>

# Instance is providing data access interface.
@record.attributes          # => {"id"=>1, "name"=>"one"}
@record.attributes["id"]    # => 1
@record.attributes["name"]  # => "one"

# Instance is holding original seed.
@record.original_seed # => "data1:\n  id: 1\n  name: \"one\"\n"
