对嵌套对象内的数组进行排序，同时保留原始 json 对象

Question

目标是按百分比对账单费率数组进行排序，同时维护原始 json 对象。

[{
    "id": 2,
    "employee_observations": [{
        "id": 1,
        "bill_rates": [{
                "bill_classification": "Lawn Mowing",
                "percentage": 0.672399672399672
            },
            {
                "bill_classification": "Trimming",
                "percentage": 0.00163800163800164
            },
            {
                "bill_classification": "Snow Removal",
                "percentage": 0.630630630630631
            },
            {
                "bill_classification": "Rock Removal",
                "percentage": 0.00163800163800164
            }
        ]
    }]
}]

预期产出

[{
    "id": 2,
    "employee_observations": [{
        "id": 1,
        "bill_rates": [
            {
                "bill_classification": "Lawn Mowing",
                "percentage": 0.672399672399672
            },
            {
                "bill_classification": "Snow Removal",
                "percentage": 0.630630630630631
            },
            {
                "bill_classification": "Rock Removal",
                "percentage": 0.00163800163800164
            },
            {
                "bill_classification": "Trimming",
                "percentage": 0.00163800163800164
            }
        ]
    }]
}]

如果我将其单独分解，我可以获得预期的结果，但尚未找到正确的组合来保持上面的嵌套版本中格式的完整性。

[
  {
    "activity_classification": "Lawn Mowing",
    "percentage": 0.672399672399672
  },
  {
    "activity_classification": "Trimming",
    "percentage": 0.00163800163800164
  },
  {
    "activity_classification": "Snow Removal",
    "percentage": 0.630630630630631
  },
  {
    "activity_classification": "Rock Removal",
    "percentage": 0.00163800163800164
  }
]

jq 'sort_by(.activity_percentage) | jq 'sort_by(.activity_percentage) | 反向' - 结果

[
  {
    "activity_classification": "Lawn Mowing",
    "percentage": 0.672399672399672
  },
  {
    "activity_classification": "Snow Removal",
    "percentage": 0.630630630630631
  },
  {
    "activity_classification": "Rock Removal",
    "percentage": 0.00163800163800164
  },
  {
    "activity_classification": "Trimming",
    "percentage": 0.00163800163800164
  }
]

使用更新运算符|=保留整体结构，并使用负比较值-.percentage按降序排序：

jq '.[].employee_observations[].bill_rates |= sort_by(-.percentage)'

[
  {
    "id": 2,
    "employee_observations": [
      {
        "id": 1,
        "bill_rates": [
          {
            "bill_classification": "Lawn Mowing",
            "percentage": 0.672399672399672
          },
          {
            "detection_classification": "Snow Removal",
            "percentage": 0.630630630630631
          },
          {
            "detection_classification": "Trimming",
            "percentage": 0.00163800163800164
          },
          {
            "detection_classification": "Rock Removal",
            "percentage": 0.00163800163800164
          }
        ]
      }
    ]
  }
]
