假设你想要
records = Model.all
records.to_a.map{|m| m.serializable_hash(:root => true)}
就像to_json(：root => true)一样
[
{
"model": {
"attribute_1": "value_1","attribute_2": "value_2",}
}
...
]
解决方法
as_json
records.as_json(:root => true)
serializable_hash
records.to_a.map() {|x|
{ x.class.model_name.element => x.serializable_hash() }
}
但这不适用于嵌套对象
