Change default configuration name of Laravel's created_at and updated_at

In this post we will give you information about Change default configuration name of Laravel's created_at and updated_at. Hear we will give you detail about Change default configuration name of Laravel's created_at and updated_atAnd how to use it also give you demo for it if it is necessary.

In this Laravel PHP Tutorial, I will let you know the use of created_at and updated_at column in a database table.

By default, Eloquent automatically maintain the date time value in created_at and updated_at column on your database table. If you do not want for eloquent to maintain created_at and updated_at columns then disable it by adding following property in your model class :

  1. class Member extends Eloquent {
  3.  protected $table='members';
  5.  public $timestamps= false;
  7. }
class Member extends Eloquent {

 protected $table = 'members';

 public $timestamps = false;

}

If you want to map Laravel's timestamp from created_at to created_on and updated_at to modified_on then you can override const on your model in following way :

const CREATED_AT = 'created_on';
const UPDATED_AT = 'modified_on';

Now Eloquent will take care of the column "created_on" and "modified_on" on your database table.
