Answer 1

I am using Laravel 8 and fixed this error through these two steps:
Move the word from $guarded array to $fillable array in User Mode.
You can put user_id in the $fillable array.
Product
{
fillable=[
'user_id',
... // other attributes
];
}
Or
Product
{
guarded = [];
}
Config.database.php: 'strict' => false in the array of 'mysql'
Note: If your problem is not solved, in your product migration make user_id as nullable.

Answer 2

in this case you must add user_id to $fillable property in Product Model. like this :
protected $fillable = [
'name', 'detail', 'image','color','logo','user_id'
];
Done...

Answer 3

make sure that $fillable in the model has the field 'user_id' like this
namespace App\Models;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
class Product extends Model
{
use HasFactory;
protected $fillable = [
'user_id',
'name',
'detail',
'image',
'color',
'logo'
];
public function user(){
return $this->belongsTo(User::class);
}
}

Answer 4

You need to specify user with id while inserting your data
$data['user_id']=$user->id;
Or Make your column user_id Nullable inthe database.
