How to use the waterline function in waterline

let config = {

  connections: {
    tmp: {
      adapter: "sails-disk"
    }
  },
  defaults: {
    migrate: "drop"
  }
};

let waterlineInstance = new waterline();
models.forEach(model => {
  if (!model.connection) {
    model.connection = "tmp";
  }
  waterlineInstance.loadCollection(waterline.Collection.extend(model));
});

function setupAssociations(models) {
  _.each(models, function eachInstantiatedModel(thisModel, modelID) {
    // Bind context for models
    // (this (breaks?)allows usage with tools like `async`)
    _.bindAll(thisModel);

    // Derive information about this model's associations from its schema
    // and attach/expose the metadata as `SomeModel.associations` (an array)
    thisModel.associations = _.reduce(

async createNewInstance () {
    this.waterline = new Waterline()
  }
