gistfile1.js

// semi-contrived example: adding a count() function to SQL collections which doesn't
// load all of the models.

// Alloy/lib/alloy/sync/sql.js

function Count() {
  var table =  model.config.adapter.collection_name;
  var sql = 'SELECT * FROM '+table;
  var rs = db.execute('SELECT COUNT(*) FROM '+table);
  return rs.isValidRow() ? rs.field(0) : 0;
}

module.exports.afterCollectionCreate = function(Collection) {
  Collection = Collection || {};

  Collection.prototype.count = Count;

  return Collection;

// Okay time to show the results. Remember this sync's local Backbone server with persistent store.
books.fetch();

// NEW: How many books do I have now?
var c = books.count();
alert(String.format("There are %d books", c));
