Mongoose Collections List Method - node.js

Question

Im new about the Mongoose. So I'm trying to do collections table.
I've this type of Schema for operators:
const operatorSchema = new Schema({
operatorName: {
type: String
},
productsSerialNumber:[{productSerialNumbers: String}],
operatorSerialNumber: {
type: Number
},
users:[{
email:String,
payment:Number,
paymentsData: Date,
}],
operatorState:{
type: Boolean,
}
});
I want to create table like this,
users using some products and I want to list which user using this product also where and when.
As below lines:
OperatorName|productsSerialNumber|username|mail|Date|Payment
But in nodejs side, I couldnt success because users is an Array and how can I get every line from database.
I'm trying like this:
const operatorArray = []
const userArray = []
exports.getOperatorInformations = (req, res, next)=>{
Operators.find({},function(err,docs){
docs.forEach(function(dataCatch){
console.log(dataCatch)
operatorArray.push(dataCatch)
res.render('home',{operators: operatorArray });
})
})
}
}
operatorArray includes all informations, so I send to ejs side:
<% operators.forEach(function(data,index){ %>
<%console.log(index)%>
<tr>
<td>
<%= data.operatorName %>
</td>
<td>
<%= data.productsSerialNumber %>
</td>
<td>
<%= data.productsSerialNumber %>
</td>
<td>
<%= data.users[index].email %>
</td>
<td>
<%= data.users[index].paymentsData %>
</td>
<td>
<!-- <%= data.users[index].payment %> -->
</td>
</tr>
<% })%>
index return length of the operators object. But I want to see lenght of user, when I try with operators.users.forEach It doesnt work. How can I do this ?

You could return the docs array directly to the ejs:
exports.getOperatorInformations = (req, res, next) => {
Operators.find({}, function (err, docs) {
if (err) console.log(err)
else res.render('home', { operators: docs });
});
};
And change your ejs to:
<% operators.forEach(function(data){ %>
<% data.users.forEach(function(user){ %>
<tr>
<td><%= data.operatorName %></td>
<td><%= data.productsSerialNumber %></td>
<td><%= data.productsSerialNumber %></td>
<td><%= user.email %></td>
<td><%= user.paymentsData %></td>
<td><!-- <%= user.payment %> --></td>
</tr>
<% })%>
<% })%>
