Nodejs not working with expand in OrientDB - node.js

var database = require('./../../models/index').database
var GError = require('./../../helper/Gerror').G_Error
var libMessage = require('./../../helper/constant')
module.exports = function (input) {
return database.select('expand(first(in("haslogin")))')
.from('Login').where({
token: input.token,
active: true
}).one()
.then(function (user) {
console.log(user)
if (!user) {
throw GError(libMessage.error.INVALID_TOKEN)
}
if (user.role !== 'admin') {
throw GError(libMessage.error.INVALID_PERMISSION)
}
return database.select().from('Product').where(
'#rid = ' + input.productId
).one()
}).then(function (product) {
if (!product) {
throw GError(libMessage.error.MISSING_PRODUCT)
}
return database.update('Product').set({
status: false
}).where('#rid = ' + input.productId)
.scalar()
}).then(function (data) {
if (!data) {
throw GError(libMessage.error.HANDLE_FAIL)
}
return {
message: libMessage.success.SUCCESSFUL.message
}
}).then(function (success) {
input.returnSuccessResponse(input.res, success)
}, function (error) {
input.returnErrorResponse(input.res, error)
})
}
I'm using nodejs and Seneca. I use the OrientDB Database. I use it to expand in OrientDB but the results are not as expected.
When I console.log (user), it produced a result: {'#rid': {[String: '# 12: 37'] cluster: 12, position: 37}}
I used the query is: select expand (first (print ("haslogin"))) from where the Login token = 'f3a93042ee17776443458b315416bfd430cb7e7ab5f85e9f39232d1093ef7c74' and active = true
Results in code and in the database is not the same

Firebase function returning null value when called from iOS app

I am making a call to a callable firebase function from my iOS app and am getting a return value of null. The correct value was returned just a few days ago, but now it's always returning null. The data is logging correctly in the console just before the return line, and there is no error appearing within the iOS call.
exports.startPlaylist = functions.https.onCall((data, context) => {
const uid = context.auth.uid;
const signature = data.signature;
return axios.post('---url----', {
data: signature
}).then(function(response) {
const val = response.data;
const ref = database.ref().push();
ref.set({
host: {
uid: uid
},
users: {
uid: uid
},
books: val
}, function(error) {
if(error) {
console.log('Not set');
} else {
const info = { id: ref.key };
console.log(info) //Correct log value appears in console
return info; //Return null, however
}
});
}).catch(function(err) {
console.log(err);
});
});
Firebase call
Functions.functions().httpsCallable("startPlaylist").call(["signature": signature]) { (result, error) in
guard let result = result, error == nil else { return }
print(result.data) //<-- prints "null"
}
As stated you should work with the promise returned by set:
ref.set({
host: {
uid: uid
},
users: {
uid: uid
},
books: val
}).then(function() {
const info = { id: ref.key };
console.log(info)
return info;
})
.catch(function(error) {
console.log('Not set');
});

use async - await with socket.io nodejs

I'm developing a web application using nodejs socket.io and angular 9. In my backend code I have written sockets in socket.connect.service.
Follows is a socket I'm using
socket.on('request-to-sit-on-the-table', async function (data, callback) { //Previously Register
let table = persistence.getTable(tableToken);
if (typeof table === 'undefined') {
let errMsg = 'This table does not exists or already closed.'
callback(prepareResponse({}, errMsg, new Error(errMsg)));
return;
}
//TODO: Get the displayName from the token.
let guest = await guestUserService.getGuestUserByPlayerToken(JSON.parse(data.userToken));***//Here is the issue***
// let displayName = 'DisplayName-' + guest;
let displayName = 'DisplayName-' + Math.random();
//TODO: Check whether the seat is available
// If the new screen name is not an empty string
let isPlayerInCurrentTable = persistence.isPlayerInCurrentTable(tableToken, userToken);
if (displayName && !isPlayerInCurrentTable) {
var nameExists = false;
let currentPlayersTokenArr = persistence.getTableObjectPlayersToken(table)
for (var token in currentPlayersTokenArr) {
let gamePlayer = persistence.getPlayerPlayer(currentPlayersTokenArr[token])
if (typeof gamePlayer !== "undefined" && gamePlayer.public.name === displayName) {
nameExists = true;
break;
}
}
if (!nameExists) {
//Emit event to inform the admin for requesting to sit on the table.
let ownerToken = persistence.getTableObjectOwnerToken(table);
let ownerSocket = persistence.getPlayerSocket(ownerToken);
ownerSocket.emit('requested-to-sit', {
seat: data.seat,
secondaryUserToken: userToken,
displayName,
numberOfChips: envConfig.defaultNumberOfChips
});
callback(prepareResponse({userToken}, 'Player connected successfully.'));
} else {
callback(prepareResponse({}, 'This name is already taken'));
}
} else {
callback(prepareResponse({}, 'This user has already joined to a game. Try clear caching'));
}
});
In my code I'm getting data from another code in guest.user.service. But I get undefined to the value of "guest"
Follows are the methods I have used in guest.user.service
exports.findById = (id) => {
return new Promise(function(resolve, reject) {
guestUserModel.findById(id, (err, data) =>{
if(err){
reject(err);
} else {
resolve(data);
}
});
});
};
exports.getGuestUserByPlayerToken = (playerToken) => {
var player = playerService.findOne({ token: playerToken })
.then(function (data) {
return self.findById(data.guestUser._id.toString());
})
.then(function (guestUser) {
return guestUser.displayName;
})
.catch(function (err) {
throw new Error(err);
})
};
Although I get my displayName for the return value It is not passed to the "guest" in my socket.Is there any syntax issue to get data as I'm using promises.please help
exports.getGuestUserByPlayerToken = async playerToken => {
try {
let player = await playerService.findOne({token:playerToken});
return playerService.findById(player.guestUser._id)
} catch(error) {
console.log(error);
return null;
}
};
This is just handle error on awaited promise not returned one. You need to handle that in caller side.

Unable to retrive data and push inside loop in node js

I am trying to retrieve attendance list along with user details.
I am using caminte.js(http://www.camintejs.com/) Cross-db ORM for database interaction.
Here is my code sample of model function "attendanceList".
exports.attendanceList = function (req, callback) {
var query = req.query;
var searchfilters = {};
if(!req.user){
callback({ code:400, status:'error', message: 'Invalid Request', data:{}});
}else{
searchfilters["vendor_id"] = parseInt(req.user._id);
}
if(query.location && parseString(query.location) != '') {
searchfilters["location"] = parseString(query.location);
}
if (query.device_details && parseString(query.device_details) != '') {
searchfilters["device_details"] = parseString(query.device_details);
}
if(query.created_on) {
searchfilters["created_on"] = query.created_on;
}
if(query.status) {
searchfilters["status"] = { regex: new RegExp(query.status.toLowerCase(), "i") };
}
var SkipRecord = 0;
var PageSize = 10;
var LimitRecord = PageSize;
var PageIndex = 1;
if(query.pagesize) {
PageSize = parseInt(query.pagesize);
}
if(query.pageindex) {
PageIndex = parseInt(query.pageindex);
}
if (PageIndex > 1) {
SkipRecord = (PageIndex - 1) * PageSize;
}
LimitRecord = PageSize;
var SortRecord = "created_on";
if(query.sortby && query.sorttype) {
var sortingBy = query.sortby;
var sortingType = 'ASC';
if(typeof query.sorttype !== 'undefined') {
sortingType = query.sorttype;
}
SortRecord = sortingBy + ' ' + sortingType;
}
Attendance.find({ where: searchfilters, order: SortRecord, limit: LimitRecord, skip: SkipRecord }, async function (err, result) {
if(err){
callback({ code:400, status:'error', message:'Unable to connect server', errors:err });
} else {
await result.map(function(row, i){
User.findById(parseInt(row.user_id), function(err, data){
if(err){
console.log(err);
} else {
result[i]['userDetails'] = data;
}
});
});
await Attendance.count({ where: searchfilters }, function (err, count) {
callback({ code:200, status:'success', message:'OK', total:count, data:result });
});
}
});
};
I am getting only attendance list without user details. How do I force to push user details into attendance list? Any Help!!
Thank You
This behavior is asynchronous. When you're making request to DB, your code keeps running, while task to get data comes to task queue.
To keep things simple, you need to use promises while handling asynchronous jobs.
Rewrite your code from this:
Attendance.find({ where: searchfilters, order: SortRecord, limit: LimitRecord, skip: SkipRecord }, async function (err, result) {
if(err){
callback({ code:400, status:'error', message:'Unable to connect server', errors:err });
} else {
await result.map(function(row, i){
User.findById(parseInt(row.user_id), function(err, data){
if(err){
console.log(err);
} else {
result[i]['userDetails'] = data;
}
});
});
await Attendance.count({ where: searchfilters }, function (err, count) {
callback({ code:200, status:'success', message:'OK', total:count, data:result });
});
}
});
To this:
const findAttendanceFirst = (searchFilters, SortRecord, LimitRecord, SkipRecord) => {
return new Promise((resolve, reject) => {
Attendance.find({ where: searchFilters, order: SortRecord, limit: LimitRecord, skip: SkipRecord }, (err, result) => {
if(err) return reject(err);
resolve(result);
});
});
}
const findUserByIdForUserDetails = (userId) => {
return new Promise((resolve, reject) => {
User.findById(parseInt(userId), function(err, data){
if(err) return reject(err);
resolve(data);
})
});
}
const getAttendanceCount = (searchFilters) => {
return new Promise((resolve, reject) => {
Attendance.count({ where: searchFilters }, (err, count) => {
if(err) return reject(err);
resolve(count);
});
})
}
So, now we can use this separate functions to make async behavior looks like sync.
try {
const data = await findAttendanceFirst(searchFilters, SortRecord, LimitRecord, SkipRecord);
for(let userData of data){
try {
userData.userDetails = await findUserByIdForUserDetails(userData.user_id);
} catch(e) {
// Some error happened, so no user details.
// you can set here null or nothing to userDetails.
}
}
let count;
try {
count = await getAttendanceCount(searchFilters);
} catch(e){
// Same as before.
}
const callBackData = { code:200, status:'success', message:'OK', total:count, data:result };
// And here you can do whatever you want with callback data. Send to client etc.
} catch(e) {
}
NB: I've not tested this code, it will be easier for yu to play with your actual data and use Promises and async/await
Just remember that each request to db is asynchronous, and you need to make your code wait for this data.

Which actually works perfectly fine in my development environment - However in production (i'm using Openshift) the mongo documents get saved in an endless loop so it looks like the (if (!doc)) condition always return true therefore the document gets created each time. Not sure if this could be a mongoose issue - I also tried the "find" method instead of "findOne". My dev env has node 0.12.7 and Openshift has 0.10.x - this could be the issue, and i'm still investigating - but if anybody can spot an error I cannot see in my logic/code please let me know
thanks!
I solved this issue by using a "series" like pattern and using the shift method on the users array. The mongoose upsert findOneOrCreate is good however if there is a found document, the document is returned, if one isn't found and therefore created, it's also returned. Therefore I could not distinguish between the newly insert doc vs. a found doc, so used the same findOne function which returns null if no doc is found I just create it and send the push notification. Still abit ugly, and I know I could have used promises or the async lib, might refactor in the future. This works for now
