I'm using Node.js and Mongoose to access a MongoDB database and return an array of objects from a MongoDB collection. However, I want to append a property to each of the returned objects. My code is shown below
router.get('/admin/manage_accounts/view_all', (req,res) => {
Community_Member.find({}, (error, community_member) => {
community_member.forEach(function(element){
element.Role = "Community Member"
})
console.log(community_member)
res.send(community_member)
})
}
The objects from the database are returned, but the Role property is not appended to any of the objects and I'm not certain why. Can anyone give me a bit of insight?
The standard functional way to do it is by using map
router.get('/admin/manage_accounts/view_all', (req,res) => {
Community_Member.find({}, (error, community_member) => {
community_member = community_member.map(element => {
element.Role = "Community Member"
return element
})
console.log(community_member)
res.send(community_member)
})
}
Editing the single element objects won't update the element in the parent array.
You could create a separate array and add the objects with the new property in it:
router.get('/admin/manage_accounts/view_all', (req,res) => {
Community_Member.find({}, (error, community_member) => {
const result = [];
community_member.forEach(function(element){
result.push({
...element,
Role: "Community Member"
})
})
console.log(result)
res.send(result)
})
}
