我正在Visual Studio 2010中创建一个asp.net mvc 3应用程序。我试图对我的模型使用FluentValidation。我使用NuGet安装了软件包(FluentValidation,FluentValidationMVC3)。我的模型如下(本论坛简化):
public class ActivityLine : AbstractValidator<ActivityLine>
{
[Key]
[Required]
public int ActivityLineId { get; set; }
public virtual ICollection<TimeModel> TimeModels { get; set; }
}
public class ActivityLineValidator : AbstractValidator<ActivityLine>
{
public ActivityLineValidator()
{
RuleFor(x => x.TimeModels).SetCollectionValidator(new TimeModelValidator());
}
}
[Validator(typeof(TimeModelValidator))]
public class TimeModel
{
[Key]
public int TimeModelId { get; set; }
[Required]
public int ActivityLineId { get; set; }
[Required]
public int LineNumber { get; set; }
public int startHours { get; set; }
public int startMinutes { get; set; }
public int endHours { get; set; }
public int endMinutes { get; set; }
public virtual ActivityLine ActivityLine { get; set; }
[NotMapped]
public TimeSpan StartTime
{
get { return new TimeSpan(startHours, startMinutes, 0); }
set { startHours = value.Hours; startMinutes = value.Minutes; }
}
[NotMapped]
public TimeSpan EndTime
{
get { return new TimeSpan(endHours, endMinutes, 0); }
set { endHours = value.Hours; endMinutes = value.Minutes; }
}
}
public class TimeModelValidator : AbstractValidator<TimeModel>
{
public TimeModelValidator()
{
RuleFor(timemodel => timemodel.endHours)
.GreaterThan(timemodel => timemodel.startHours)
.WithMessage("Start Time Must be before End Time");
}
}
在我的控制器中:
[HttpPost]
public ActionResult Create(ActivityLine model)
{
if (ModelState.IsValid)
{
personnel.ActivityLines.Add(model);
personnel.SaveChanges();
return RedirectToAction("Index");
}
//Model State Not Valid Redisplay Form
return View(model);
}
即使我为TimeModel和TimeModel实例分配了无效值,ModelState也始终为true。当项目击中人员时,该项目就会爆炸.SaveChagnes()行。我收到“No Source Available”错误。详情如下:
Locating source for 'c:\Projects\FluentValidation\src\FluentValidation\Attributes\ValidatorAttribute.cs'. Checksum: MD5 {e3 d4 90 62 70 f7 a6 4e 9e ac 62 71 77 21 64 dd}

我认为我的配置有问题,但我无法弄清楚是什么。有没有人使用Fluent有这个问题?我需要做些什么来解决它?我的项目位于网络共享上,如果这会产生影响。
答案 0 :(得分:1)
您的ActivityLine域模型不应派生自AbstractValidator。它应该使用Validator属性进行修饰,就像使用TimeModel
:
[Validator(typeof(ActivityLineValidator))]
public class ActivityLine
{
[Key]
[Required]
public int ActivityLineId { get; set; }
public virtual ICollection<TimeModel> TimeModels { get; set; }
}
public class ActivityLineValidator : AbstractValidator<ActivityLine>
{
public ActivityLineValidator()
{
RuleFor(x => x.TimeModels).SetCollectionValidator(new TimeModelValidator());
}
}
另外,请确保Application_Start
中有以下行,以启用FluentValidation元数据提供程序,如documentation中所述:
FluentValidationModelValidatorProvider.Configure();
就personnel.SaveChagnes()
行的轰炸而言,这与ASP.NET MVC和FluentValidation.NET都没有任何关系。我想这是你正在使用的数据访问技术,你遇到了问题。
