How to convert JSON object structure to dot notation?

Question

I\'ve got a variable I\'m storing that will dictate what fields to exclude from a query:

excludeFields = {
  Contact: {
    Address: 0,
    Phone: 0
  }
}
         


        

Answer 1

var fields = {};
for (var k in excludeFields) {
  for (var p in excludeFields[k]) {
    fields[k + '.' + p] = excludeFields[k][p];
  }
}

Then:

things.findOne({}, {fields: fields})
