Question

我有一个嵌套类型，我需要获取特定对象的索引来执行更新：

{
  "_index": "asset_en_v1",
  "_type": "note",
  "_id": "23217",
  "_version": 24,
  "found": true,
  "_source": {
    "user_id": "11",
    "title": "Title",
    "note": "Note.",
    "creation": "2017-05-31T21:36:01",
    "modification": "2017-05-31T21:36:01",
    "links": [
      {
        "note_link_id": "7310",
        "user_id": "11",
        "creation": "2017-06-01T14:41:50",
        "modification": "2019-06-01T14:42:00",
        "comment": "Comment goes here."
      },
      {
        "note_link_id": "7311",
        "user_id": "11",
        "creation": "2017-06-01T14:42:42",
        "modification": "2019-06-01T14:42:00",
        "comment": "Yep..."
      },
      {
        "note_link_id": "7312",
        "user_id": "11",
        "creation": "2017-06-01T15:33:55",
        "modification": "2017-06-01T15:34:00",
        "comment": "Jumo."
      }
    ]
  }
}

到目前为止，我已经在无痛脚本中创建了一个_update语句，几乎完成了这项工作，但我很难获得匹配：

{
    "script": {
        "lang": "painless",
        "inline": "def note_link_id = 7311; def links = ctx._source.links; for (int i = 0; i < links.length; ++i) { if (links[i].note_link_id == note_link_id) { ctx._source.links[note_link_id].comment = params.comment; ctx._source.links[note_link_id].modification = params.modification } }",
        "params": {
            "modification": "2019-06-01T14:42:00",
            "comment": "QWERTY!"
        }
    }
}

此处links[i].note_link_id == note_link_id不匹配。

有什么想法吗？

在你的内联脚本中，应该是i ++，而不是++ i

def note_link_id = 7311; 
def links = ctx._source.links; 
for (int i = 0; i < links.length; i++) //Note i++, instead of ++i
{ 
    if (links[i].note_link_id == note_link_id) 
    { 
        ctx._source.links[note_link_id].comment = params.comment;
        ctx._source.links[note_link_id].modification = params.modification 
    } 
}
