我想使用一个渲染非null属性的序列化程序
class PersonSerializer < ActiveModel::Serializer
attributes :id,:name,:phone,:address,:email
end
这可能吗.
非常感谢.
解：
class PersonSerializer < ActiveModel::Serializer
attributes :id,:email
def attributes
hash = super
hash.each {|key,value|
if value.nil?
hash.delete(key)
end
}
hash
end
end
解决方法
从active_model_serializer gem的0.10.x版本开始,您必须覆盖方法serializable_hash而不是属性：
# place this 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
