Before (Missing Generic Types)

use Illuminate\Database\Eloquent\Relations\BelongsTo;

class User extends Model
{
    public function company(): BelongsTo
    {
        return $this->belongsTo(Company::class);
    }
}

After (With Generic Types)

use Illuminate\Database\Eloquent\Relations\BelongsTo;

class User extends Model
{
    /**
     * @return BelongsTo<Company, self>
     */
    public function company(): BelongsTo
    {
        return $this->belongsTo(Company::class);
    }
}

use Rector\Config\RectorConfig;
use RectorLaravelCustomRules\Rules\LaravelEloquentGenericRector;

return RectorConfig::configure()

    ]);

What This Rector Does

This Rector automatically adds generic type annotations to Laravel Eloquent relationship methods, improving type safety and IDE support by adding proper PHPDoc annotations like @return BelongsTo<Company, self>.
