I'm writing a blog engine using express, and ran into a problem when trying to run a mongoose query through a function:
What I'm trying to do is to obtain a variable that contains the next and previous blog posts by id, to do that I wrote this function:
middleware.getAdjacentPosts = async function(_id) {
var adjacentPosts = {}
await Post.findOne({ _id: { $gt: _id } }).sort({ _id: 1 }).exec(async function(err, nextPost) {
if (err) {
console.log(err)
} else {
if (nextPost == null) {
adjacentPosts.nextPost = false;
} else {
adjacentPosts.nextPostUrl = nextPost.slug;
adjacentPosts.nextPostTitle = nextPost.title;
}
await Post.findOne({ _id: { $lt: _id } }).sort({ _id: -1 }).exec(
async function(err, previousPost) {
if (err) {
console.log(err.message);
} else {
if (previousPost == null) {
adjacentPosts.previousPost = false;
} else {
adjacentPosts.previousPostUrl = previousPost.slug;
adjacentPosts.previousPostTitle = previousPost.title;
}
console.log(adjacentPosts)
return adjacentPosts
}
})
}
})
}
Before returning, I can see the variable completed with what I need through the console.log. The problem I have is that when I try to execute the function, the receiving variable is empty. This would be executed in the get route for a post, like the following:
Router.get("/posts/:slug", async function(req, res) {
await Post.findOne({ slug: req.params.slug }).populate('categories').populate('comments').exec(async function(err, foundBlog) {
if (err) {
console.log(err.message)
} else {
var posts = {}
posts = await middleware.getAdjacentPosts(foundBlog._id)
console.log(posts)
res.render("frontoffice/post", {
blog: foundBlog,
postUrl: req.params.slug,
adj: posts,
reCaptchaSiteKey: process.env.CAPTCHA_SITE_KEY
})
}
})
})
Any clues of what I might be doing wrong?
As #LucaKiebel suggests, you will need to return the results from your findOnes:
middleware.getAdjacentPosts = async function(_id) {
var adjacentPosts = {};
return await Post.findOne({ _id: { $gt: _id } })
.sort({ _id: 1 })
.exec(async function(err, nextPost) {
if (err) {
console.log(err);
} else {
if (nextPost == null) {
adjacentPosts.nextPost = false;
} else {
adjacentPosts.nextPostUrl = nextPost.slug;
adjacentPosts.nextPostTitle = nextPost.title;
}
return await Post.findOne({ _id: { $lt: _id } })
.sort({ _id: -1 })
.exec(async function(err, previousPost) {
if (err) {
console.log(err.message);
} else {
if (previousPost == null) {
adjacentPosts.previousPost = false;
} else {
adjacentPosts.previousPostUrl = previousPost.slug;
adjacentPosts.previousPostTitle = previousPost.title;
}
console.log(adjacentPosts);
return adjacentPosts;
}
});
}
});
};
A potential improvement, since you are using async/await anyway, might be to get rid of the callbacks:
middleware.getAdjacentPosts = async function(_id) {
var adjacentPosts = {};
try {
const nextPost = await Post.findOne({ _id: { $gt: _id } }).sort({ _id: 1 });
if (nextPost == null) {
adjacentPosts.nextPost = false;
} else {
adjacentPosts.nextPostUrl = nextPost.slug;
adjacentPosts.nextPostTitle = nextPost.title;
}
const previousPost = await Post.findOne({ _id: { $lt: _id } }).sort({ _id: -1 })
if (previousPost == null) {
adjacentPosts.previousPost = false;
} else {
adjacentPosts.previousPostUrl = previousPost.slug;
adjacentPosts.previousPostTitle = previousPost.title;
}
console.log(adjacentPosts);
return adjacentPosts;
} catch (err) {
console.log(err);
}
};

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.
I have a remote method in loopback like:
Alerts.getAlertDetails = function (alertId, options, cb) {
var response = {};
var userId = options.accessToken.userId;
Alerts.app.models.MobileUserAlertRelation.find({where: {userId: userId, alertId: alertId, isDeleted: -1}, include: {relation: 'alerts', scope: {include: ['alertTypes'], where: {status: 1}}}}, function (err, alertRel) {
if (alertRel.length > 0 && alertRel[0].alerts()) {
response.code = 200;
response.status = "success";
response.data = {};
if (alertRel[0].alertId) {
response.data.alertId = alertRel[0].alertId;
}
if (alertRel[0].readStatus) {
response.data.readStatus = alertRel[0].readStatus;
}
if (alertRel[0].receivedOn) {
response.data.alertReceivedOn = alertRel[0].receivedOn;
}
var alertData = alertRel[0].alerts();
if (alertData.title) {
response.data.alertTitle = alertData.title;
}
if (alertData.message) {
response.data.alertShortMessage = alertData.message;
}
if (alertData.extraMessage) {
response.data.alertMessage = alertData.extraMessage;
}
if (alertData.priority) {
response.data.alertPriority = alertData.priority;
}
if (alertData.validUntil) {
response.data.alertExpiresOn = alertData.validUntil;
}
if (alertData.images && alertData.images.length > 0) {
response.data.alertImages = [];
for (var image in alertData.images) {
if (alertData.images.hasOwnProperty(image)) {
response.data.alertImages.push(constants.ALERT_IMAGE_URL + '/' + alertData.images[image]);
}
}
}
if (alertData.alertTypes() && alertData.alertTypes().alertTypeName) {
response.data.alertType = alertData.alertTypes().alertTypeName;
}
if (alertData.alertLocations && alertData.alertLocations > 0) {
response.data.alertLocations = [];
response.data.policeDepartments = [];
response.data.hospitals = [];
response.data.fireDepartments = [];
var locations = alertData.alertLocations;
for (var locKey in locations) {
if (locations.hasOwnProperty(locKey)) {
if (locations[locKey].data) {
response.data.alertLocations.push(locations[locKey].data);
console.log(locations[locKey].data);
if (locations[locKey].data.type) {
var locationType = locations[locKey].data.type;
if (locationType === "Polygon") {
var coordinates = locations[locKey].data.coordinates[0];
var polygonCenter = getPolygonCenter(coordinates);
console.log(polygonCenter);
}
}
}
}
}
}
cb(null, response);
} else {
response.code = 404;
response.status = 'error';
response.message = 'Alert not found.';
cb(null, response);
}
})
};
But when I call this method through api, response is received without data added from the complex code part. I know that callback will be called asynchronously here and so that cb(response) will be called before the complex code is executed completely. How can i send response only after the complex part is completed and data is correctly added to response from that data. I cannot move cb(response) inside the complex part as data is being pushed in for loop.
I have heard of promises, can it be used here, if so, how could it be done?
Someone please help!!
The problem is because of fetching relation in if.
The relation method is an async.
Alerts.getAlertDetails = function (alertId, options, cb) {
var response = {};
var userId = options.accessToken.userId;
Alerts.app.models.MobileUserAlertRelation.find({where: {userId: userId, alertId: alertId, isDeleted: -1}, include: {relation: 'alerts', scope: {include: ['alertTypes'], where: {status: 1}}}}, function (err, alertRel) {
if(alertRel.length < 1){
return handleError();
}
alertRel[0].alerts(handleResponse);
function handleResponse(err, alertRelAlert){
if(err) return handleError();
if (alertRelAlert) {
//all that code in question if if section
}else {
return handleError();
}
}
function handleError(){
response.code = 404;
response.status = 'error';
response.message = 'Alert not found.';
cb(null, response);
}
});
}

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
