如何以编程方式更新表1的标题。
这是一种静态的方法:
db.books.update({_id: ObjectId("5757646866e59fac8d1d8589")},
{$set: {"books.0.chapters.0.tables.0.heading": "new Heading"}})
我想做的是这样的事情:
db.books.update({_id: ObjectId("5757646866e59fac8d1d8589"),
'books.id': '1',
'books.chapters.id':'1',
'books.chapters.tables.table':'1' },
{$set: {<what>}})
