是否有任何属性可以避免验证模型？

Question

我的控制器中有以下操作：

[HttpGet]
public ActionResult Office(GestionOffice model)
{
    ModelState.Clear();
    model.Initialize();
    return View(model);
}

我不需要GET采取行动，进行验证。这将有助于我通过GET进行调用。

这将是我理想的情况：

[HttpGet]
[NotValidateModel]
public ActionResult Office(GestionOffice model)
{
    model.Initialize();
    return View(model);
}

谢谢。

修改

NotValidateModel澄清说不存在，会将案件归咎于避免验证。

移动模型的原因是MOCK模型

编辑II

我有POST的动作，我需要通过GET接收我的动作，没有验证的模型，成功完成控制器中动作的测试

[HttpGet]
[NotValidateModel]
public ActionResult Office(GestionOffice model)
{
    model.Initialize();
    return View(model);
}

[HttpPost]
[ActionName("Office")]
[NotValidateModel]
public ActionResult OfficePost(GestionOffice model)
{
    if(ModelState.IsValid)
    {
        model.Save();
        return RedirectToAction("List");
    }

    model.Initialize();
    return View(model);
}

关于@Mark解决方案的版本

在我看来，我有几个动作调用，我不得不用动作和控制器创建一个键。

自定义ModelMetaData

public class CustomModelMetaData : ModelMetadata
{
    public CustomModelMetaData(ModelMetadataProvider provider, Type containerType, Func<object> modelAccessor, Type modelType, string propertyName)
        : base(provider, containerType, modelAccessor, modelType, propertyName)
    {
    }

    public override IEnumerable<ModelValidator> GetValidators(ControllerContext context)
    {
        var itemKey = this.CreateKey(context.RouteData);
        if (context.HttpContext.Items[itemKey] != null && bool.Parse(context.HttpContext.Items[itemKey].ToString()) == true)
        {
            return Enumerable.Empty<ModelValidator>();
        }

        return base.GetValidators(context);
    }

    private string CreateKey(RouteData routeData)
    {
        var action = (routeData.Values["action"] ?? null).ToString().ToLower();
        var controller = (routeData.Values["controller"] ?? null).ToString().ToLower();
        return string.Format("NoValidation_{0}_{1}", controller, action);
    }
}

过滤

public class NoValidationAttribute : FilterAttribute, IAuthorizationFilter
{
    public void OnAuthorization(AuthorizationContext filterContext)
    {
        var itemKey = this.CreateKey(filterContext.ActionDescriptor);
        filterContext.HttpContext.Items.Add(itemKey, true);
    }

    private string CreateKey(ActionDescriptor actionDescriptor)
    {
        var action = actionDescriptor.ActionName.ToLower();
        var controller = actionDescriptor.ControllerDescriptor.ControllerName.ToLower();
        return string.Format("NoValidation_{0}_{1}", controller, action);
    }
}

修改过滤器

可能存在在主视图中使用foreach调用具有属性NoValidation的多个部分视图的情况。在这种情况下，包括检查密钥的控件。因为它包含控制器的名称和键中的动作，这个键几乎是唯一的，它只能在描述的情况下重复

public class NoValidationAttribute : FilterAttribute, IAuthorizationFilter
{
    public void OnAuthorization(AuthorizationContext filterContext)
    {
        var itemKey = this.CreateKey(filterContext.ActionDescriptor);
        if (!filterContext.HttpContext.Items.Contains(itemKey))
        {
            filterContext.HttpContext.Items.Add(itemKey, true);
        }
    }

    private string CreateKey(ActionDescriptor actionDescriptor)
    {
        var action = actionDescriptor.ActionName.ToLower();
        var controller = actionDescriptor.ControllerDescriptor.ControllerName.ToLower();
        return string.Format("NoValidation_{0}_{1}", controller, action);
    }
}

Answer 1

[请参阅@ANDRES在问题中提到的编辑更新

你想要做的事情有点难以实现，我不确定你为什么要这样做。我试图通过自定义ModelMetaData和过滤器（未完全测试）来完成。

我们无法从模型绑定器或元数据提供程序中读取操作所装饰的属性，因此我们需要一个过滤器。过滤器在HttpContext.Items中放置了一些值，我们可以从自定义元数据提供程序中检索它（ http://stackoverflow.com/questions/6198155/asp-net-mvc-modelbinder-getting-action-方法）。

过滤

public class NoValidationAttribute : FilterAttribute, IAuthorizationFilter
{
    public void OnAuthorization(AuthorizationContext filterContext)
    {
      // please see the edits in question to see the key generation
      filterContext.HttpContext.Items.Add("NoValidation", true);
    }
}

自定义ModelMetaData

public class CustomModelMetaData : ModelMetadata
{
    public CustomModelMetaData(ModelMetadataProvider provider, Type containerType, Func<object> modelAccessor, Type modelType, string propertyName) :
      base(provider, containerType, modelAccessor, modelType, propertyName)
    {
    }

    public override System.Collections.Generic.IEnumerable<ModelValidator> GetValidators(ControllerContext context)
    {
      if (context.HttpContext.Items["NoValidation"] != null && bool.Parse(context.HttpContext.Items["NoValidation"].ToString()) == true)
        return Enumerable.Empty<ModelValidator>();

      return base.GetValidators(context);
    }
}

自定义ModelMetaDataProvider

public class CustomModelMetaDataProvider : DataAnnotationsModelMetadataProvider
{
    protected override ModelMetadata CreateMetadata(System.Collections.Generic.IEnumerable<Attribute> attributes,
      Type containerType, Func<object> modelAccessor,
      Type modelType,
      string propertyName)
    {
      return new CustomModelMetaData(this, containerType, modelAccessor, modelType, 
         propertyName); 
    }
}

<强>的Global.asax.cs

ModelMetadataProviders.Current = new CustomModelMetaDataProvider();

<强>用法

[HttpGet]
[NoValidation]
public ActionResult Office(GestionOffice model)
{
   ...
}

================================= 更新 ====== ===============================

不是通过继承CustomModelMetaData来创建ModelMetadata，而是认为继承DataAnnotationsModelMetadata会很好。

public class CustomModelMetaData : DataAnnotationsModelMetadata
{
    public CustomModelMetaData(DataAnnotationsModelMetadataProvider provider, Type containerType,   
            Func<object> modelAccessor, Type modelType, string propertyName,            
            DisplayColumnAttribute displayColumnAttribute) :            
    base(provider, containerType, modelAccessor, modelType, propertyName, displayColumnAttribute)
    {
    }

    public override IEnumerable<ModelValidator> GetValidators(ControllerContext context)
    {
        var itemKey = this.CreateKey(context.RouteData);

        if (context.HttpContext.Items[itemKey] != null && 
           bool.Parse(context.HttpContext.Items[itemKey].ToString()) == true)
        {
             return Enumerable.Empty<ModelValidator>();
        }

        return base.GetValidators(context);
    }

    private string CreateKey(RouteData routeData)
    {
       var action = (routeData.Values["action"] ?? null).ToString().ToLower();
       var controller = (routeData.Values["controller"] ?? null).ToString().ToLower();
       return string.Format("NoValidation_{0}_{1}", controller, action);
    }
}

在CustomModelMetaDataProvider中，您必须设置一些属性。

public class CustomModelMetaDataProvider : DataAnnotationsModelMetadataProvider
{
    protected override ModelMetadata CreateMetadata(IEnumerable<Attribute> attributes,
      Type containerType, Func<object> modelAccessor, Type modelType, string propertyName)
    {
      var displayColumnAttribute = new List<Attribute>(attributes).OfType<DisplayColumnAttribute>().FirstOrDefault();

      var baseMetaData = base.CreateMetadata(attributes, containerType, modelAccessor, modelType, propertyName);

      // is there any other good strategy to copy the properties?
      return new CustomModelMetaData(this, containerType, modelAccessor, modelType,  propertyName, displayColumnAttribute)
      {
        TemplateHint = baseMetaData.TemplateHint,
        HideSurroundingHtml = baseMetaData.HideSurroundingHtml,
        DataTypeName = baseMetaData.DataTypeName,
        IsReadOnly = baseMetaData.IsReadOnly,
        NullDisplayText = baseMetaData.NullDisplayText,
        DisplayFormatString = baseMetaData.DisplayFormatString,
        ConvertEmptyStringToNull = baseMetaData.ConvertEmptyStringToNull,
        EditFormatString = baseMetaData.EditFormatString,
        ShowForDisplay = baseMetaData.ShowForDisplay,
        ShowForEdit = baseMetaData.ShowForEdit,
        Description = baseMetaData.Description,
        ShortDisplayName = baseMetaData.ShortDisplayName,
        Watermark = baseMetaData.Watermark,
        Order = baseMetaData.Order,
        DisplayName = baseMetaData.DisplayName,
        IsRequired = baseMetaData.IsRequired
      };
    }
}

Answer 2

是的，您使用[ValidateInput(false)]属性，如下所示：

[ValidateInput(false)]
[HttpGet]
public ActionResult Office(GestionOffice model)
{
    model.Initialize();
    return View(model);
}

Answer 3

如果您想在生产代码中使用而不进行验证，则需要禁用客户端验证，因为在服务器端它将被禁用。

将web.config修改为fallows：

<appSettings>
    <add key="ClientValidationEnabled" value="false" />
</appSettings>

Answer 4

验证在POST中进行，因此您必须删除Model.IsValid并添加[ValidateInput(false)]

[HttpPost]
[ValidateInput(false)]
[ActionName("Office")]
public ActionResult OfficePost(GestionOffice model)
{        
    model.Save();
    return RedirectToAction("List");
}

现在帖子会成功，但如果你插入数据库，你必须小心。
