rails传递记录数组(JSON）

rails Passing array of records (in JSON)

本文关键字：JSON 数组 记录 rails      更新时间：2023-09-26

我已经用Javascript生成了一个JSON格式的记录数组，我想在控制器中创建多个记录。我传递这些数据：

[
{"trip_id":0,"arrival_time":0,"departure_time":0,"stop_id":0,"stop_sequence":0},{"trip_id":1,"arrival_time":1,"departure_time":1,"stop_id":1,"stop_sequence":1},
{"trip_id":2,"arrival_time":2,"departure_time":2,"stop_id":2,"stop_sequence":2},{"trip_id":3,"arrival_time":3,"departure_time":3,"stop_id":3,"stop_sequence":3},
{"trip_id":4,"arrival_time":4,"departure_time":4,"stop_id":4,"stop_sequence":4},{"trip_id":5,"arrival_time":5,"departure_time":5,"stop_id":5,"stop_sequence":5},
{"trip_id":6,"arrival_time":6,"departure_time":6,"stop_id":6,"stop_sequence":6},{"trip_id":7,"arrival_time":7,"departure_time":7,"stop_id":7,"stop_sequence":7},
{"trip_id":8,"arrival_time":8,"departure_time":8,"stop_id":8,"stop_sequence":8},{"trip_id":9,"arrival_time":9,"departure_time":9,"stop_id":9,"stop_sequence":9}
]

我试着或多或少地这样做：

def create
params.each do |stop_time|
  StopTime.create stop_time
end
...

，但我不知道如何获取每条记录（如：id？或其他什么？）。

谢谢，

params对象中通常有一个键与此数据关联。你能提供更多关于params散列中内容的信息吗？否则，我会说这就是你所缺少的。

params[:some_key_with_that_array_of_stop_times].each do |stop_time|
  StopTime.create stop_time
end
