ruby-on-rails - 使用JBuilder在Rails中创建嵌套的JSON输出

Question

我正在寻找有关如何使用JBuilder创建嵌套JSON输出的示例。

我想创建和输出类似于以下内容:

{
    "name": "John Doe", 
    "reservations": [
        {
            "restaurant": "ABC",
            "reservation_time": "2012/12/01 20:00", 
            "details": {
                "address": "somewhere", 
                "rating": "5"
            }
        }, 
        {
            "restaurant": "CDE",
            "reservation_time": "2012/12/04 20:00", 
            "details": {
                "address": "somewhere else", 
                "rating": "3"
            }
        }
    ]
}

解决了:

json.name user.name

json.array!(@reservations) do |json, reservation|
    json.restaurant reservation.restaurant.name
    json.reservation_time reservation.time

    json.details do 
        json.address reservation.restaurant.address 
        json.rating reservation.restaurant.rating 
    end
end
