Iterate MongoDB collection to pug - node.js

Question

I'm trying to display a MongoDB collection of employees into Pug. I know it has something to do with the first 'data' object. I cannot figure out how to render the data within the array.
MongoDB collection:
{
"data":[
{
"active":true,
"userName":"example",
"employeeDetails":{
"personalDetails":{
"firstName":"Dennis",
"lastName":"Glover",
"emailAddress":"example#example.com"
}
}
},
{
"active": false,
"userName": example2,
"employeeDetails": {
"personalDetails": {
"firstName": "Ben",
"lastName": "Dover",
"emailAddress": "example2#example.com"
}
}
},
]
}
Express:
MongoClient.connect(url, function(err, db) {
if (err) {
console.log('Unable to connect to the Server', err);
} else {
console.log('Connection established to', url);
var employeecollection = db.collection('employees');
// Find all employees
employeecollection.find({}).toArray(function(err, employeeResult) {
if (err) {
res.send(err);
} else if (employeeResult.length) {
res.render('employeelist', {
'employeelist': employeeResult,
});
} else {
res.send('No documents found');
}
db.close();
});
};
});
Pug:
table
each employee in employeelist
tr#employee_list_item
td #{employee.userName}
I have fiddled around got it working with Angular2 using ng-repeat, however I cannot seem to get it to render in Pug unless I strip out the 'data' object in the array (which needs to be there).

Answer 1

As much as I can see employeelist[0].data is the array you want to iterate on.
Change employeelist to employeelist[0].data
table
each employee in employeelist[0].data
tr#employee_list_item
td #{employee.userName}
Update. Alternative method:
As Mohit suggested, if you send from the route itself, then your original code will work.
// Find all employees
employeecollection.find({}).toArray(function(err, employeeResult) {
if (err) {
res.send(err);
} else if (employeeResult.length) {
res.render('employeelist', {
'employeelist': employeeResult[0].data,
});
} else {
res.send('No documents found');
}
db.close();
});
Then, in your view:
Pug
table
each employee in employeelist
tr#employee_list_item
td #{employee.userName}
Hope this helps you!
