How to use select on azure search suggesters

I'm using Azure search on my project, and I want to do an autocomplete text field, it works as expected. here's the code :
const suggestItems = async (req, res) => {
try {
// Reading inputs from HTTP Request
const q = (req.query.q || (req.body && req.body.q));
const top = (req.query.top || (req.body && req.body.top));
const suggester = (req.query.suggester || (req.body && req.body.suggester));
// Let's get the top 5 suggestions for that search term
const suggestions = await client.suggest(q, suggester, { top: parseInt(top) });
//const suggestions = await client.autocomplete(q, suggester, {top: parseInt(top)});
console.log(suggestions.results)
return res.status(status.OK)
.json({ suggestions: suggestions.results})
} catch (error) {
handleError(res, error)
}
}
her's the result :
[
{ text: 'Alpha Aromatics (MA)', document: { id: '4' } },
{ text: 'Alpha Aromatics (USA)', document: { id: '5' } },
{ text: 'Art Land - Winter Palace', document: { id: '6' } },
{ text: 'Alpha Aromatics (USA)', document: { id: '3' } }
]
here's the quesry passed by postman :
{
"q":"ar","top":5,"suggester":"sg"
}
but the problem is , on the result I have just the text and the id of the document , I'm looking for other fields like status for example, how can get that please ?

I am guessing "Status" is one of your index fields, from the question. You need to make sure you mark the fields you need to be returned in the results as retrievable in your index definition. It looks you only have text and id fields as retrievable. For more information: https://learn.microsoft.com/en-us/azure/search/search-what-is-an-index.
Example:

Mongoose - CastError Cast to string failed for value "Object"

I have Mongoose CastError issue. I made a nodeJs API. At the specific route, it returns data appended with some other data. I saw many fixes available here but my scenario is different.
Here is my model and the problem occurs at fields property.
const deviceSchema = new Schema({
device_id: { type: String, required: true },
user_id: { type: Schema.Types.ObjectId, ref: 'User', require: true },
location_latitude: { type: String, default: '0' },
location_longitude: { type: String, default: '0' },
fields: [{ type: String }],
field_id: { type: Schema.Types.ObjectId, ref: 'Field', required: true },
timestamp: {
type: Date,
default: Date.now,
},
});
and my controller is
exports.getAllDevices = async (req, res) => {
try {
let devices = await Device.find({})
.sort({
timestamp: 'desc',
})
.populate('user_id', ['name']);
// Let us get the last value of each field
for (let i = 0; i < devices.length; i++) {
for (let j = 0; j < devices[i].fields.length; j++) {
if (devices[i].fields[j] !== null && devices[i].fields[j] !== '') {
await influx
.query(
`select last(${devices[i].fields[j]}), ${devices[i].fields[j]} from mqtt_consumer where topic = '${devices[i].device_id}'`
)
.then((results) => {
************** Problem occurs here **************
if (results.length > 0) {
devices[i].fields[j] = {
name: devices[i].fields[j],
last: results[0].last,
};
} else {
devices[i].fields[j] = {
name: devices[i].fields[j],
last: 0,
};
}
************** Problem occurs here **************
});
}
}
}
// Return the results
res.status(200).json({
status: 'Success',
length: devices.length,
data: devices,
});
} catch (err) {
console.log(err);
res.status(500).json({
error: err,
});
}
};
It actually gets data from InfluxDB and appends it to fields property which was fetched from MongoDB as mentioned in my model. But it refused to append and CastError occurs.
After addition, it will look like this
I can't resolve this error after trying so many fixes. I don't know where I'm wrong. Please suggest to me some solution for this.

I can see you are not using devices variable as Mongoose Document. devices is an array of Documents.
I would like to suggest you to use lean() function to convert from Document to plain JavaScript object like
let devices = await Device.find({})
.sort({
timestamp: 'desc',
})
.populate('user_id', ['name'])
.lean();

How to access array elements that are defined in another array of Mongoose scheme object Array?

This is the User schema in mongoose:
var userSchema = new mongoose.Schema({
email: {
type: String,
unique: true,
required: true,
},
name: {
type: String,
required: true,
},
Addtasks: [
{
topic: String,
words: Number,
keywords: String,
website: String,
otherdetails: String,
exampleRadios: String,
deadline: Date,
Date: String,
fileName: String,
Bigpaths: [],
},
],
});
module.exports = mongoose.model('User', userSchema);
I want to use/access the Bigpaths array, which is defined inside the Addtasks array, which is defined in User. Data is already are there in mongoDB, which I have inserted via UI page. I am trying the following code but I am getting this error in console:
data.Addtasks[Object.keys(data.Addtasks).length - 2].Bigpaths.forEach(
(element) => {
// ...
}
)
as
TypeError: Cannot read property 'Bigpaths' of undefined
at \Desktop\grumpytext\routes\index.js:99:71
Code:
const { files } = req;
User.findOne({ email: req.user.email }, function (error, data) {
if (error) {
console.log('Three');
} else if (data) {
if (Object.keys(data.Addtasks).length > 1) {
data.Addtasks[Object.keys(data.Addtasks).length - 2].Bigpaths.forEach(
(element) => {
files.forEach((currentElement) => {
if (element.name == currentElement.filename) {
files.pull(currentElement.filename);
}
});
}
);
}
}
});
How to resolve this error or how to access all the elements of Bigpaths array so that I can iterate it with forEach loop?

I'm not sure here, but I think you need to populate Addtasks prior to manipulating it:
const files = req.files;
User.findOne({email:req.user.email}).populate('Addtasks').exec((error, data) => {
if (error) {
console.log("Three");
}
else
{
if(data)
{
if(Object.keys(data.Addtasks).length > 1)
{
console.log("Addtasks count: " + Object.keys(data.Addtasks).length);
data.Addtasks[Object.keys(data.Addtasks).length - 2].Bigpaths.forEach(element => {
files.forEach(currentElement => {
if(element.name == currentElement.filename)
{
files.pull(currentElement.filename);
}
})
});
}
}
}
});
Please notice the log console.log("Addtasks count: " + Object.keys(data.Addtasks).length); - in case the solution does not work, I advise to add some prints, especially to check if the count of elements is as expected or properties within an object are fine.

Meteor subscription inside setState

I was able to write subscription in meteor and it is working fine. now i need to set state inside the Meteor getMeteorData() method. here is my implemented working method
getMeteorData() {
Meteor.subscribe('Posts', Meteor.userId());
return {
Posts: Posts.find({}, {
sort: {
createdAt: -1
}
}).fetch(),
};
}
also i want it to be something like this. mean i want to set the state inside function. but when i code like below it return exception on the console.
getMeteorData() {
Meteor.subscribe('Posts', Meteor.userId());
let medias = [];
Posts.map(post => {
post.images.map(image => {
medias.push({image: image, post: post})
})
});
this.setState({medias: medias});
return {
Posts: Posts.find({}, {
sort: {
createdAt: -1
}
}).fetch(),
};
}
below is the snap of error error snap

Update element from user profile in Meteor

I am trying to update firstName field created in user.profile using onCreateUser:
Accounts.onCreateUser(function(options, user) {
user.profile = options.profile || {};
user.profile.firstName = options.firstName;
return user;
});
Also I use allow:
Meteor.users.allow({
update: function(userId, doc, fields, modifier) {
if (fields === "profile.firstName") {
return true;
}
}
});
When I use:
Meteor.users.update({
_id: Meteor.userId()
}, {
$set: {
profile: "George"
}
});
It works but it is not what I need.
What I need is to update firstName:
Meteor.users.update({
_id: Meteor.userId()
}, {
$set: {
profile.firstName: "George"
}
});
But I get this error:
SyntaxError: missing : after property id
What am I missing?

If you are using the dot notation you need to enclose the whole dotted field name in quotes.
In your case:
Meteor.users.update({
_id: Meteor.userId()
}, {
$set: {
"profile.firstName": "George"
}
});
