Loopback DB Connection code

For API errors in Loopback, create a new schemaupdate.js file in server\boot to correct any errors for GET and POST calls.

var async = require('async');

module.exports = function(app, cb) {
  var datasources = Object.keys(app.dataSources);
  async.eachSeries(datasources, function(dsName, cb) {
    var ds = app.dataSources[dsName];
    ds.isActual(function(err, actual) {
      if (err) return cb(err);
      if (actual) { console.log('datasource', dsName, 'is up to date'); return cb(); }
      ds.autoupdate(function(err) {
        if (err) return cb(err);
        console.log('datasource', dsName, 'updated');
        cb();
      });
    });
  }, cb);
};
