serialization - Rails ActiveModel Serializers render not null attributes -

i want use serializer renders not null attributes

     class personserializer < activemodel::serializer         attributes :id, :name, :phone, :address, :email      end 

is possible.

many thanks.

solution:

 class personserializer < activemodel::serializer     attributes :id, :name, :phone, :address, :email     def attributes      hash = super      hash.each {|key, value|       if value.nil?       hash.delete(key)      end     }     hash    end   end 

from version 0.10.x of active_model_serializer gem, have override method serializable_hash instead of attributes:

# place method inside nullattributesremover or directly inside serializer class def serializable_hash(adapter_options = nil, options = {}, adapter_instance = self.class.serialization_adapter_instance)   hash = super   hash.each { |key, value| hash.delete(key) if value.nil? }   hash end
