我在mongoDB中有数据,如下所示
{
"_id": ObjectId("57c40e405e62b1f02c445ccc"),"sharedPersonId": ObjectId("570dec75cf30bf4c09679deb"),"notificationDetails": [
{
"userId": "57443657ee5b5ccc30c4e6f8","userName": "Kevin","isRed": true
}
]
}
现在我想将isRed值更新为false如何为此编写查询.我尝试过类似下面的内容
var updateIsRedField = function(db,callback) {
db.collection('notifications').update({_id:notificationId},{
$set: { "notificationDetails.$": {isRed: false}},},function(err,results) {
callback();
});
};
MongoClient.connect(config.database,db) {
assert.equal(null,err);
updateIsRedField(db,function() {
db.close();
});
return res.json({});
});
