How can I post an array of Schema.Types.ObjectId (s) to MongoDB? I'm trying to create User Groups, which is a group of the 'User' Model eg
var UserGroup = new Schema({
users: [{
type: Schema.Types.ObjectId,
ref: 'User'
}]
});
New UserGroup Function
module.exports.create = function(request, response) {
var group = new UserGroup({
users = request.body.users
});
group.save(function(error) {
if(error) { throw error; } else { response.send('Group Created Successfully.');
});
};
I'm currently using Postman to test the functionality, how exactly should the data be posted?
As a Javascript array ie ['A_USER_ID', 'A_USER_ID']
?
Thanks!
@Answer
I was using the older syntax of the select() function, and therefore was passing invalid parameters to the $push function. When sending the request, I simply pass the ObjectIds
as id,id,id
and once they get to the server, simply put it into an array using var my_array = request.body.users.split(',');
and then push it to the database using the following:
$push: { users: { $each: my_array } }
I hope this was helpful, the documentation isn't particularly clear on this matter.
