pushing object to an array giving me empty array

Question

hi all i have this code where i select data from a database and want to insert them as objects inside an array :

conn2.query('SELECT date, action FROM actions WHERE ?', [{
  issue_id: data.id
}], function(error, data2) {
  if (error) {
    showNotification('Error :' + error, 'danger', 'glyphicon glyphicon-tasks');
  } else {
    data2.forEach(function(data21) {
      res.push({
        "date": data21.date,
        "description": data21.action
      });
      console.log(res);
    });
  }
});

the problem is that the res is alwayes empty .... if i

console.log({"date": data21.date,"description": data21.action})

it give me the right object .... seems that the push is not write.

Edited: thanks every body i could't solve this problem so i used officegen which did the job nicely

Maybe the query returns noting and data2 is an empty array, thus res.push never gets called? Add console.log('data2', data2) to the beginning of the callback function. — tiblu

I think you must have not declared res as an array object res = [] Or maybe the data2 is empty

Can you try

res.push({date: data21.date,description: data21.action});
console.log(JSON.stringify(res));
console.log(res.toString());
