Elastic attributes
Flexible attribute mapper. Input any ruby structure, map sub-structures to specified classes.
Can be used to map decoded JSON structures to objects, e.g. with document-oriented databases or JSON APIs.
Examples
class Person
include ElasticAttributes
attribute :name, :is_default => true
end
class City
include ElasticAttributes
attribute :name, :is_default => true
attribute :mayor, Person
end
class Country
include ElasticAttributes
attribute :name, :is_default => true
attribute :cities, [Array, City] # Array of Cities
end
Country.from( 'Hungary' )
Country.from( {'name' => 'Hungary'} )
Country.from( {'name' => 'Hungary', 'cities' => ['Budapest', 'Miskolc', 'Debrecen']} )
Country.from( {'name' => 'Hungary', 'cities' => [{'name' => 'Budapest', 'mayor' => 'Demszky Gabor'},
'Miskolc',
'Debrecen']} )
City.from( {'name' => 'Budapest', 'mayor' => 'Demszky Gabor'} )
city = City.from( {'name' => 'Budapest', 'mayor' => {'name' => 'Demszky Gabor'}} )
city.encode # => {"name"=>"Budapest", "mayor"=>"Demszky Gabor"}
