将元素添加到对象数组中，然后使用新数组

Question

I'm loading json file from hdd then I'm adding for every object id element.Further I wanna save this array into database like "bulkCreate" not create (make insert sql query for each object) for every object in array.

var file = 'data.json';
jf.readFile(file, function(err, obj) {

    _.forEach(obj, function(n, key) {
        n.id = new.id;
  });

});

How Can I access to my edited array outside for-each ? I wanna save it then like :

Model
  .bulkCreate(mynewarray)
  .on('success', function(new) { ... });

Thanks a lot for any opinion!

Answer 1

You should be able to call Model .bulkCreate right after the _.forEach() statement as it is modifying obj .

I'm assuming the json file contains an array of objects

var file = 'data.json';
jf.readFile(file, function(err, obj) {

  _.forEach(obj, function(n) {
    n.id = new.id;
  });

  Model.bulkCreate(obj).on('success', function(new) { ... });

});
