node.js - findOneAndUpdate with push array elements gives error in mongoose -


my query shown below:

const updatelikes = (item_id, userinfo) => {     return new promise((resolve, reject) => {         itemlike.findoneandupdate({ 'item_id': item_id }, { $inc: { no_of_likes: 1 } }, { "$push": { "users": userinfo } }, { 'new': true }, (err, info) => {             if (err) {                 reject(err);             } else {                 if (info) {                     resolve();                 } else {                     reject('no item found');                 }             }         });     }); };

itemlike.js

const itemlike = new schema({     item_id: { type: mongoose.schema.objectid, ref: 'items', index: true },     no_of_likes: { type: number, default: 0 },     users: [{ type: mongoose.schema.objectid, ref: 'user' }] }, { versionkey: false });   module.exports = mongoose.model('item_like', itemlike);

as execute query , error shown below:

events.js:160       throw er; // unhandled 'error' event       ^  typeerror: callback.apply not function     @ query.<anonymous> (c:\users\anand\quflipapi\node_modules\mongoose\lib\model.js:3702:16)     @ c:\users\anand\quflipapi\node_modules\kareem\index.js:273:21     @ c:\users\anand\quflipapi\node_modules\kareem\index.js:127:16     @ _combinedtickcallback (internal/process/next_tick.js:67:7)     @ process._tickdomaincallback (internal/process/next_tick.js:122:9)

am missing here?

looking @ docs findoneandupdate, think you're providing 1 many parameters.

it should conditions, update, options, callback. you're getting error because mongoose trying invoke { 'new': true } callback function.

it looks update definition has been split 2 objects mistake. need remove braces highlighted in bold below.

{ $inc: { no_of_likes: 1 } }, { "$push": { "users": userinfo } }

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
