Merhaba arkada\u015flar, bildi\u011finiz \u00fczere .Net Core ve Web API derslerine ba\u015flad\u0131k. \u0130lk dersimizde Dependecy Injection’a teorik bir giri\u015f yap\u0131p, Microsoft’un kendi Dependency Injection k\u00fct\u00fcphanesi ve 3rd party bir k\u00fct\u00fcphane olan Autofac’i kullanarak \u00f6rnekler yapt\u0131k. O yaz\u0131m\u0131za da buradan<\/a> ula\u015fabilirsiniz.<\/p>\n\n\n\n

Database Entity’leri bir \u00e7ok sebepten dolay\u0131 Frontend tarafta kullan\u0131lmaz. Entity Framework, ad\u0131ndan da anla\u015f\u0131laca\u011f\u0131 \u00fczere entity’leri kullan\u0131r. Ve veritaban\u0131 i\u015flemleri de bu entityler vas\u0131tas\u0131yla ger\u00e7ekle\u015fir. Peki e\u011fer entity’leri frontend’te kullanam\u0131yorsak, frontend’teki verileri nas\u0131l veritaban\u0131na kaydedece\u011fiz? Modellerin yada Dto’lar\u0131n de\u011ferlerinin entitylere setlenmesi gerekir. Her ne kadar k\u00fc\u00e7\u00fck projeler \u00e7ok y\u00fcksek miktarda property’lere sahip s\u0131n\u0131flar\u0131 bar\u0131nd\u0131rmasa da, projeler b\u00fcy\u00fcd\u00fck\u00e7e ve mod\u00fcllerin birbirleri olan ili\u015fkileri fazlala\u015ft\u0131k\u00e7a s\u0131n\u0131flar\u0131n i\u00e7indeki property’lerin say\u0131s\u0131 da artar. Dolay\u0131s\u0131yla model\/dto property de\u011ferlerinin entitylere setlenme i\u015flemi g\u00fc\u00e7 bir hale gelir.<\/p>\n\n\n\n

\u0130\u015fte bu noktada, AutoMapper devreye giriyor ve birka\u00e7 sat\u0131r kodla devasa verileri nesneler aras\u0131nda setleyebiliyoruz. Hadi ba\u015flayal\u0131m!<\/p>\n\n\n\n

AutoMapper.Extensions.Microsoft.DependencyInjection<\/code><\/pre>\n\n\n\n
Yukar\u0131daki NuGet paketini projemize ekliyoruz.<\/p>\n\n\n\n
public void ConfigureServices(IServiceCollection services)\n    {\n        services.AddAutoMapper(typeof(Startup));\n        services.AddControllersWithViews();\n    }<\/code><\/pre>\n\n\n\n
Startup s\u0131n\u0131f\u0131m\u0131z i\u00e7erisinde ConfigureServices methodunu yukar\u0131daki gibi AddAutoMapper() methodunu \u00e7a\u011f\u0131rarak projeye AutoMapper ekleme i\u015flemi tamamlan\u0131r. <\/p>\n\n\n\n
\u015eimdi a\u015fa\u011f\u0131daki gibi SampleModel ad\u0131nda bir s\u0131n\u0131f olu\u015fturuyoruz.<\/p>\n\n\n\n
public class SampleModel\n{\n    public Guid Id { get; set; }\n    public string Name { get; set; }\n    public string Surname { get; set; }\n    public DateTime Birthdate { get; set; }\n    public string Job { get; set; }\n}<\/code><\/pre>\n\n\n\n
 Bu bizim \u00f6n tarafta verilerimizin tutulaca\u011f\u0131 s\u0131n\u0131f olacak. Bunun d\u0131\u015f\u0131nda arka tarafta kullan\u0131lacak DataModel isimli s\u0131n\u0131f\u0131 da a\u015fa\u011f\u0131daki gibi olu\u015fturuyoruz.<\/p>\n\n\n\n
 public class DataModel\n {\n    public Guid Id { get; set; }\n    public string Name { get; set; }\n    public string Surname { get; set; }\n    public DateTime Birthdate { get; set; }\n    public string Job { get; set; }\n }<\/code><\/pre>\n\n\n\n
\u015eimdi AutoMapper kullan\u0131larak bir SampleModel<\/em> nesnesindeki datalar, DataModel<\/em> s\u0131n\u0131f\u0131ndan bir nesneye aktar\u0131lacak. Bu i\u015flem i\u00e7in son bir ad\u0131m\u0131m\u0131z kald\u0131 ve o da MappingProfile s\u0131n\u0131f\u0131n\u0131 olu\u015fturmak ve AutoMapper’a maplemelerin yap\u0131laca\u011f\u0131 s\u0131n\u0131flar\u0131 bildirmek. Bunu yapabilmek ad\u0131na SampleDataMappingProfile<\/em> isminde a\u015fa\u011f\u0131daki gibi bir s\u0131n\u0131f olu\u015fturuyoruz.<\/p>\n\n\n\n
public class SampleDataMappingProfile:Profile\n{\n    public SampleDataMappingProfile()\n    {\n        CreateMap<SampleModel, DataModel>().ReverseMap();\n    }\n}<\/code><\/pre>\n\n\n\n
Dependency Injection yard\u0131m\u0131yla AutoMapper instance’\u0131n\u0131 al\u0131yoruz ve onun yard\u0131m\u0131yla Maplemeyi yap\u0131yoruz. <\/p>\n\n\n\n
public class HomeController : Controller\n{\n    \/\/ AutoMapper nesnesi\n    private readonly IMapper _mapper;\n    public HomeController(IMapper mapper)\n    {\n        _mapper = mapper;\n    }\n\n    public IActionResult Index()\n    {\n        \/\/ model nesnesi yerine veri kayna\u011f\u0131 olan nesne gelecek\n        var model = new SampleModel() { Id = Guid.NewGuid(), Name = \"Test\", Surname = \"Test\", Birthdate = DateTime.Now };\n        var mapped = _mapper.Map<DataModel>(model);\n        return View();\n    }\n}<\/code><\/pre>\n\n\n\n
G\u00f6rd\u00fc\u011f\u00fcn\u00fcz gibi model nesnesinin t\u00fcm de\u011ferleri oldu\u011fu gibi mapped nesnesine tek sat\u0131r kodla aktar\u0131ld\u0131. Bu y\u00f6ntem, 4-5 tane property’si olan s\u0131n\u0131flar i\u00e7in \u00e7ok \u00f6nemli olmasa da 30-40 property’li s\u0131n\u0131flarda yaz\u0131l\u0131mc\u0131y\u0131 b\u00fcy\u00fck bir y\u00fckten kurtarmaktad\u0131r.
