How to configure unique key with multiple field in SimpleSchema

Question

I'm using SimpleSchema in meteor app. Now I need to define unique key with multiple field. In a Collection I have field like

servingDate, vanId, timeSlot

I need to make a unique with those three fields. Is there any possibilities to do in SimpleSchema ??

Answer 1

You cannot do that from with a simple schema configuration. Your only valid option is:

if (Meteor.isServer) {
  MyCollection._ensureIndex(
    {servingDate: 1, vanId: 1, timeSlot: 1},
    { unique: true }
  );
}
