How to solve attempt to read property "id" on null (Laravel-8)-CodePudding

I got this error while running php artisan migrate:fresh --seed this command will create table in MySQL database and fill the database details DB_DATABASE in .env file.

    parent::boot();
    static::creating(function($model)
    {
    $user = Auth::user();
    model->created_by = $user->id ? $user->id : 1 ;
      });
      static::updating(function($model)
      {
       $user = Auth::user();```


Controller:

CodePudding user response：

The issue here is that the value of $user is null and null doesn't have any properties.

$user will always be null with your code as Auth::user() will be null. You have no authenticated User during the execution of your seeder.

If you want to assign a User to your $model and you have seeded your User table, you could get a User that way.

$model->created_by = \App\Models\User::where('id', 5)->first();

If you don't want a particular User then you could do:

$model->created_by = \App\Models\User::inRandomOrder()->first();

CodePudding user response：

Change this line:

model->created_by = $user->id ? $user->id : 1 ;

to this:

model->created_by = $user ? $user->id : 1 ;

You must first check if the $user is empty or not.
