Saving last user changed database record for Eloquent models (Laravel 5)
Please be aware that this trait uses Auth facade
and expects it to implement Illuminate\Contracts\Auth\Guard contract, (*1)
How it works
Quite simple actually, just before saving row to database, this trait gets id of current user using Auth::user()->id (thats why requirements above exists) and write it to specified database field (for more specifics read the Installation and configuration section), (*2)
Installation and configuration
This trait can be installed via composer. Just add following to your composer.json file:, (*3)
{
"require": {
"constant-null/eloquent-changed-by": "~0.1"
}
}
and then run:, (*4)
$ composer update
To start using this trait you need to import it to Eloquent model, (*5)
<?php
use ConstantNull\Eloquent\Support\ChangedByUser;
use Illuminate\Database\Eloquent\Model;
class SomeModel extends Model
{
use ChangedByUser;
/* The rest of the your class */
}
and add column to database in which user id will be stored. Like this for example:, (*6)
<?php
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class BestMigrationEver extends Migration
{
public function up()
{
Schema::table('some_table', function(Blueprint $table) {
$table->integer('changed_by')->nullable();
});
}
How you can see in example the default column name for user id is changed_by, but it can be easily changed by specifying constant CHANGED_BY in your class body., (*7)
For example i want this column name to be 'last_user_id':, (*8)
<?php
use ConstantNull\Eloquent\Support\ChangedByUser;
use Illuminate\Database\Eloquent\Model;
class SomeModel extends Model
{
use ChangedByUser;
const CHANGED_BY = 'last_user_id';
/* Rest part of the your class */
}
Thats all!, (*9)
