将嵌套数组对象分组到 JQ 中的父键

Question

我有 JSON 来自外部应用程序，格式如下：

   {
      "ticket_fields": [
      {
        "url": "https://example.com/1122334455.json",
        "id": 1122334455,
        "type": "tagger",
        "custom_field_options": [
          {
            "id": 123456789,
            "name": "I have a problem",
            "raw_name": "I have a problem",
            "value": "help_i_have_problem",
            "default": false
          },
          {
            "id": 456789123,
            "name": "I have feedback",
            "raw_name": "I have feedback",
            "value": "help_i_have_feedback",
            "default": false
          },
        ]
      }
      {
        "url": "https://example.com/6677889900.json",
        "id": 6677889900,
        "type": "tagger",
        "custom_field_options": [
          {
            "id": 321654987,
            "name": "United States,
            "raw_name": "United States",
            "value": "location_123_united_states",
            "default": false
          },
          {
            "id": 987456321,
            "name": "Germany",
            "raw_name": "Germany",
            "value": "location_456_germany",
            "default": false
          }
        ]
      }
    ]
  }

最终目标是能够将数据放入 TSV，因为 custom_field_options 数组中的每个对象都按父 ID (ticket_fields.id) 分组，然后转置这样每个对象都将在一行中表示，如下所示：

Ticket Field ID	Name	Value
1122334455	I have a problem	help_i_have_problem
1122334455	I have feedback	help_i_have_feedback
6677889900	United States	location_123_united_states
6677889900	Germany	location_456_germany

我已经能够将数据成功导出到 TSV，但它是按行读取的，并且没有保留顺序，如下所示：

使用jq -r '.ticket_fields[] | select(.type=="tagger") | [.id, .custom_field_options[].name, .custom_field_options[].value] | @tsv'

Ticket Field ID	Name	Name	Value	Value
1122334455	I have a problem	I have feedback	help_i_have_problem	help_i_have_feedback
6677889900	United States	Germany	location_123_united_states	location_456_germany

生产中的每个 custom_field_options 数组都可以包含任意数量的对象（每个对象不限于 2 个）。但我似乎对如何适当地将这些对象分组或映射到它们的父对象 ticket_fields.id 以及如何以干净的方式转置数据感到困惑。查询中提到了 select(.type=="tagger")，因为 ticket_fields.type 有多个值需要过滤掉。

您需要两个嵌套迭代，每个数组中一个。将 .id 的值保存在变量中以便稍后访问它。

jq -r '
  .ticket_fields[] | select(.type=="tagger") | .id as $id
  | .custom_field_options[] | [$id, .name, .value]
  | @tsv
'
