Code Quality Assessment

Laravel Conventions

// ❌ Bad - Not following Laravel conventions
class user_controller extends Controller
{
    public function get_user($user_id) {
        $user = DB::select("SELECT * FROM users WHERE id = $user_id");
        return $user;
    }
}

// ✅ Good - Follows Laravel conventions
class UserController extends Controller
{
    public function show(User $user)
    {
        return new UserResource($user);
    }
}

Controller Review

• Skinny controllers (logic in services/actions)
• Form requests for validation
• Resource transformation for API responses
• Proper HTTP status codes
• Authorization via policies
• No business logic in controllers

Model Review

// ❌ Bad - Missing protection and relationships
class Post extends Model
{
    protected $guarded = []; // Dangerous!
    
    public function getComments() {
        return Comment::where('post_id', $this->id)->get();
    }
}

// ✅ Good - Proper model setup
class Post extends Model
{
    protected $fillable = ['title', 'content', 'status'];
    
    protected $casts = [
        'published_at' => 'datetime',
        'metadata' => 'array',
    ];
    
    public function comments(): HasMany
    {
        return $this->hasMany(Comment::class);
    }
    
    public function scopePublished($query)
    {
        return $query->where('status', 'published');
    }
}
