Unique indexes not working.

I’ve got a problem with creating unique indexes using Mongoose / MongoDb and can’t get it work, I’m able to add two documents with the same attribute values when I have set a unique index.

I’ve tried everything I can think of - restarting (everything) changing the syntax etc.

code

    var Something = new Schema({
    objectId          : ObjectId,
    name              : { type : String, index: { unique: true }}, 
    url               : { type : String, index: { unique: true }},
    ...etc
    mongoose.model('Something', Something);

…

This is the method that I’m using to save an entity:

create  : function(entity, definition, successFn, errorFn){ 

var model = mongoose.model(entity);
newModel = new model(definition);

newModel.save(function(error) {
  if(error){
    if(!errorFn){
      throw error;
    }
    errorFn(newModel);
    return;
  }

  successFn(newModel);
});

}…

Mongo output

 [conn1] insert xxxxx.agencies 1526ms
 [conn1] building new index on { name: 1 } for xxxxx.agencies
 [conn1] insert xxxxx.system.indexes exception 11000 E11000 duplicate key error    index: xxxxx.agencies.$name_1  dup key: { : "something" } 4ms
 [conn1] building new index on { url: 1 } for xxxxx.agencies
 [conn1] insert xxxxx.system.indexes exception 11000 E11000 duplicate key error index: xxxxx.agencies.$url_1  dup key: { : "http://www.something.com" } 1ms

When I checked in MongoHub the indexes don’t appear, so they don’t look like they have been created.

Perhaps what happened is that the index were first created non-unique and later the unique attribute was added, but Mongoose didn’t create the index as unique indexes because it saw the indexes already existed.

markstos, solution work for me. Drop your existing collection and reconnect it again
