为什么验证在我的模型上没有正确发生?

当属性不正确时,ModelState.IsValid被设置为true。我用Requied,Minimum / MaxLength等装饰了字段,但ModelState.IsValid bool返回true。

这是因为我正在测试时跳过模型绑定而它实际上并没有执行验证吗?

[Authorize(Roles = "A")]
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult AddProject(Projects project)
{
    if (project == null)
    {
        return HttpNotFound();
    }

    if (ModelState.IsValid)
    {
        using (var db = new DbContext())
        {
            db.ProjectModels.Add(project);
            db.SaveChanges(); //exception raised here.
        }
        return RedirectToAction("ListOfProjects", "Project");
    }
    return View("AddProject", project);
}

[TestMethod()]
public void AddProjectTestWithModel()
{
    //initialize
    var controller = new AdminController();
    var model = new Projects()
    {
        Name = "Project",
        Description = "Description",
        Duration = "1 Month"
    };
    var nullModel = new Projects();
    nullModel = null;
    var invalidModel = model;
    invalidModel.Description = null;
    invalidModel.Name = null;

    //setup
    var result = (RedirectToRouteResult)controller.AddProject(model) as RedirectToRouteResult;
    var modelFromDb = db.ProjectModels.Find(model.Id);
    var result2 = (HttpNotFoundResult)controller.AddProject(nullModel) as HttpNotFoundResult;
    var result3 = (ViewResult)controller.AddProject(invalidModel) as ViewResult;

    Assert.AreEqual("ListOfProjects", result.RouteValues["action"]);
    Assert.AreEqual(404, result2.StatusCode);
    Assert.AreEqual("AddProject", result3.ViewName); //UnitTest fails here.
}

知道为什么吗?我希望result3是ViewResult而ViewName是“AddProject”,因为ModelState.IsValid bool应该是false。为什么? :(

答案 0 :(得分:0)

找到解决方案。当发布的数据绑定到查看模型时,将进行验证。当ibis直接进入控制器时,这将被跳过。 viewmodel是传递给控制器​​的东西,一旦模型发布和绑定是在检查验证之前,在它进入控制器之前,这就是为什么在测试表单时断开指向代码永远不会破坏,因为它不会甚至到达控制器。

希望你有类似的问题是有意义的。
