node.js - Mongo updating inside a double nested array -


i have mongo collection looks this

db.users.find().pretty() {     "_id" : objectid("57c3d5b3d364e624b4470dfb"),     "fullname" : "tim",     "username" : "tim",     "email" : "tim@gmail.com",     "password" : "$2a$10$.z9cnk4okrc/cujdkxt6yutohqkhbaanuoahtxqp.73kfywrm5dy2",     "workout" : [         {             "workoutid" : "bkb6hiws",             "workoutname" : "chest day",             "bodytarget" : "chest",             "date" : "monday, august 29th, 2016, 2:27:04 am",             "exercises" : [                 {                     "exerciseid" : "bym88lzi",                     "exercise" : "bench press",                     "date" : "monday, august 29th, 2016, 2:29:30 am"                 },                 {                     "exerciseid" : "byu8ii-s",                     "exercise" : "flys",                     "date" : "monday, august 29th, 2016, 2:29:34 am"                 }             ]         },         {             "workoutid" : "bk_tri-o",             "workoutname" : "back day",             "bodytarget" : "back",             "date" : "monday, august 29th, 2016, 2:27:12 am"         }     ] }

so want this

db.users.find().pretty() {     "_id" : objectid("57c3d5b3d364e624b4470dfb"),`enter code here`     "fullname" : "tim",     "username" : "tim",     "email" : "tim@gmail.com",     "password" : "$2a$10$.z9cnk4okrc/cujdkxt6yutohqkhbaanuoahtxqp.73kfywrm5dy2",     "workout" : [         {             "workoutid" : "bkb6hiws",             "workoutname" : "chest day",             "bodytarget" : "chest",             "date" : "monday, august 29th, 2016, 2:27:04 am",             "exercises" : [                 {                     "exerciseid" : "bym88lzi",                     "exercise" : "bench press",                     "date" : "monday, august 29th, 2016, 2:29:30 am",                     "stats" : [                           {                             "reps: '5',                             "weight":'105'                           }                 },                 {                     "exerciseid" : "byu8ii-s",                     "exercise" : "flys",                     "date" : "monday, august 29th, 2016, 2:29:34 am"                 }             ]         },         {             "workoutid" : "bk_tri-o",             "workoutname" : "back day",             "bodytarget" : "back",             "date" : "monday, august 29th, 2016, 2:27:12 am"         }     ] }

i want add stats array current exercise array. having trouble dot notation double nested array

i tried this

db.users.update({   'email': 'jeffreyyourman@gmail.com', "workout.workoutid": "bkb6hiws" ,"workout.exercises.exerciseid":"byu8ii-s" }, {   $push: {           "workout.0.exercises.$.stats": {"sets":"sets", "reps":"reps"}}})

which works push first nested exercises object.

now if this...

db.users.update({   'email': 'jeffreyyourman@gmail.com', "workout.workoutid": "bkb6hiws" ,"workout.exercises.exerciseid":"byu8ii-s" }, {   $push: {           "workout.0.exercises.1.stats": {"sets":"sets", "reps":"reps"}}})

and replace $ 1 push second exercises array want. building website can't hard code in. need use $ doesn't seem make past first exercises object.

any appreciate !

db.users.update({   'email': 'jeffreyyourman@gmail.com',    "workout.workoutid": "bkb6hiws",   "workout.exercises.exerciseid":"byu8ii-s" },

this query part returning first matching object, whole user profile rather exercise entry. can specify email same object. "workoutid" , "exerciseid" redundant.

{   $push: {     "workout.0.exercises.$.stats": {"sets":"sets", "reps":"reps"}   } })

thus push command push first entry of exercise amiram said in comment. in case, can retrieve entire object, modify it, , save.

but think need redesign schema better performance. maybe make schema workout , exercise, use reference connect them. http://mongoosejs.com/docs/populate.html

c# - Check Keyboard Input Winforms -

i wondering if instead of doing this protected override void onkeydown(keyeventargs e) { if (e.keycode == keys.a) console.writeline("the key down."); } i set bool method , this: if(keydown(keys.a)) // whatever here i've been sitting here ages trying figure out how it. can't wrap head around it. in case wondering, plan call bool inside different method, check input. since want perform action after pressing key, using keydown event enough. but in cases suppose want check if specific key down in middle of process, can use getkeystate method way: [dllimport("user32.dll", charset = charset.auto, exactspelling = true)] public static extern short getkeystate(int keycode); public const int key_pressed = 0x8000; public static bool iskeydown(keys key) { return convert.toboolean(getkeystate((int)key) & key_pressed); } you should know, each time check key state using example iskeydown(keys.a) method returns true if ke...
