This gem is mongoDB mapper that allows you to save, destroy and load any custom object with deep nested core/custom attributes.
At actual version the only restriction is, that objects you want to save/load, cannot have initializers with arguments-passing or they provide optional params values if nothing is passed(nil, hash, etc.).
Below are few examples of using gem.
class CoolClass
attr_accessor :cool_attr
include DumbSerializer
def initialize
@cool_attr = NestedClass.new
end
end
class NestedClass
attr_accessor :nested_attr
def initialize
@nested_attr = 9
end
endYou would usually use document id to find it, but in any case, insertion result is being returned from #serialize.
object = CoolClass.new
id = object.dump.inserted_id.to_s #=> '562f8ab72d27c231fb000003'CoolClass.find(id) #=> <CoolClass:0x000000016ad438 @cool_attr = <NestedClass:0x000000016ad439
# @nested_attr = 9>, @config_attr={:cool_attr=>0}>
CoolClass.all #=> array of saved objects.drop method drops collection belonging to class.
CoolClass.remove(id)
CoolClass.dropYou can configure database connection with .db_config= by passing options like database, host, port.
Beware of configuration. If you set it up for one class it will influence setup of other classes that include DumpSerializer.
# These are defaults
CoolClass.db_config #=> { database: 'dumb_serializer', host: '127.0.0.1', port: '27017'}
CoolClass.db_config = { database: 'custom' }
CoolClass.db_config #=> { database: 'custom', host: '127.0.0.1', port: '27017'}
