javascript - Node.js update elements in MongoDB -

-

i have following mongoose schema , model:

var deviceschema = new schema({     deviceid:string,     devicename:string,     deviceplace:string,      socket : [{number: number,name:string, state : boolean, current: number, image:number,locked:boolean,reserved:boolean}] });

i have device in database 4 sockets.

here example!

this original data.

{     "_id" : objectid("5626569006bc3da468bafe93"),     "deviceid" : "0013a20040b5769a",     "devicename" : "device",     "deviceplace" : "place",     "__v" : 0,     "socket" : [          {             "_id" : objectid("5628bd83570be84e28879e2d"),             "number" : 0,             "name" : "name"             "state" : true,             "current" : 0             "image" : 0,             "locked" : false,             "reserved" : false,         }, ...     ] }

and received data client update.

{     "_id" : objectid("5626569006bc3da468bafe93"),     "deviceid" : "0013a20040b5769a",     "__v" : 0,     "socket" : [          {             "_id" : objectid("5628bd83570be84e28879e2d"),             "number" : 0,             "name" : "new name!!!!!"             "state" : true,             "current" : 0         }, ...      ] }

now i'm trying update specific socket's name in database following command:

device.update({deviceid: newdata.deviceid, "socket.number": newdata.number}, {$set: {"socket.$.name": newdata.name}})

newdata object extracted socket array in received data.

i want update first socket's name. or if possible, want update every socket's name received socket array.

but not seem working, no error. can pin point i'm doing wrong?

what isshellcommand property , how should use it? the description when hovering says: "specifies whether command shell command or external programm. defaults false if omitted" and in https://code.visualstudio.com/docs/editor/tasks mention in example with: "we want run gulp command in shell (vs code directly executing it) used isshellcommand" so difference between shell command vs external program? does running isshellcommand = false mean vscode not "directly executing it" meaning run "command" , don´t listen output (because ran external command?) in turn means cannot use problem matchers. or if setting isshellcommand = true mean vscode "directly executing it" , keep track of , listen output generated can use problem matchers etc integrate vscode? considering example below using tsc compile typescript project: c:\users\j\code\vscode-project>where tsc c:\program files (x86)\microsoft sdks\typescript\1.4\tsc.exe ...
