Question

我为自定义视图模板创建了一个viewmodel类。现在我在Controller类中调用数据库保存方法。现在我想把这个逻辑移到Repository类。如何在我的存储库类中访问我的viewModel特性？我很感激任何意见。谢谢。

这是我的代码。

视图模型

    public SelectList StatusList { get; set; }
    [Required(ErrorMessage = "* Required")]
    public string Status { get; set; }

    [Required]
    public DateTime? StartDate { get; set; }

我的控制器类：

[HttpPost]
    public ActionResult Create(CreateViewModel viewModel)
    {
        if (ModelState.IsValid)
        {
            // go and save your view model data  
            using (var adapter = new DataAccessAdapter())
            {
                    TestEntity test1 = new TestEntity();
                    test1.statusId = Convert.ToInt32(viewModel.Status);
                    adapter.SaveEntity(test1);

                    TestEntity1 test2 = new TestEntity2();
                    test2.mId = test1.mId;
                    test2.startDate = viewModel.startDate;
                    adapter.SaveEntity(test2);
           }
        }

}

您不希望访问存储库中的视图模型属性，您希望将视图模型属性映射回实体类并将实体传递到存储库。该实体应该位于MVC应用程序和数据库都知道的库中。

public class TestController
{
  public ITestRepository _repository;

  public TestController(ITestRepository repository)
  {
    _repository = repository;
  }

  public ActionResult Create(CreateViewModel viewModel)
  {
    var entity = new TestEntity()
      { statusId = Int32.Parse(viewModel.Status) };
    var entity2 = new TestEntity2()
      { mId = entity.mId,
        startDate = viewModel.startDate };

    _repository.SaveEntity(entity);
    _repository.SaveEntity2(entity2);
  }
}

我如何将viewmodel类传递给存储库类
