MongoDB/Mongoose:MarkModified 嵌套对象 [英] MongoDB / Mongoose: MarkModified a nested object

问题描述

不幸的是，我没有可以对此进行测试的记录，但我无法在任何地方找到有关此的任何信息.

Unfortunately I don't have a record I can test this on, but I can't find any information on this anywhere.

假设我有一个这样的文档:

Say I have a document like this:

{
  email:  {
       type: 'Gmail',
       data: {//freeform data},
    }
}

我想更新doc.email.data.我需要使用 markModified() 否则数据将无法正确保存.

I want to update doc.email.data. I need to use markModified() or else the data won't save correctly.

我是否像这样标记修改过?

Do I mark modified like this?

doc.email.data = newData;
doc.markModified('email.data');
doc.save();

或者我只做 markModified('email') 而 Mongoose 会解决其余的问题?

Or do I just do markModified('email') and Mongoose will work out the rest?

推荐答案

你需要提供修改对象字段的完整路径，所以应该是:

You need to provide the full path the modified object field, so it should be:

doc.markModified('email.data');
