PouchDb-删除文档中的对象 [英] PouchDb - remove object inside document

问题描述

我是意大利的PouchDb和AngularJS开发人员。
我的json文档是：

I'm an Italian PouchDb and AngularJS Developer. My json document is:

{
   "_id": "6",
   "_rev": "3-f7283d7683cd6fb15753f494aad1d49f",
   "name": "Ivrea",
   "owners": [
       {
           "owner_id": 1,
           "name": "asdas",
           "address": "asdas",
           "gender": "Uomo",
           "type": "Assente",
           "notes": [
           ]
       },
       {
           "owner_id": 2,
           "name": "balbaba",
           "address": "blabla",
           "gender": "Uomo",
           "type": "Assente",
           "notes": [
           ]
       }
   ]
}

，然后按 ng次操作，我将删除 _id：6 文档中的 owner_id：2 对象。在API参考中，我仅找到文档删除操作，而没有找到如何删除文档中的对象。

and after an ng-click action, I will delete owner_id: 2 object inside _id: 6 document. In API reference I found only document delete action, but not how to delete object inside document.

感谢您的答复！

推荐答案

您只需要 put（）从数据库中删除对象后，将主文档返回数据库。 ：）

You just need to put() the main document back in the database after you remove an object from it. :)

db.get('foo').then(function (doc) {
  delete doc.whatever;
  return db.put(doc);
}).catch(function (err) { /* ... */ });
