Looking to assign a randomly generated string property to every item in a MongoDB collection. Planning to leverage the mongo shell and the updateMany function for a swift and efficient solution.
Looking to assign a randomly generated string property to every item in a MongoDB collection. Planning to leverage the mongo shell and the updateMany function for a swift and efficient solution.
After conducting some research, I came across a solution that worked well for me:
function generateID(length) {
var result = '';
var characters = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789';
var charactersLength = characters.length;
for ( var i = 0; i < length; i++ ) {
result += characters.charAt(Math.floor(Math.random() *
charactersLength));
}
return result;
}
console.log(generateID(5));
To confirm its functionality in your mongo shell, try typing generateID(6)
Implement the function on each document to assign a unique randomly generated property:
db.collectionName.find({}).forEach(function(myDocument) {db.collectionName.update({_id: myDocument._id}, {$set: { randomId: generateID(6)}})})
