FluentValidation 調用規則集和通用規則

Question

我有以下課程

public class ValidProjectHeader : AbstractValidator<Projects.ProjectHeader>
    {
        public ValidProjectHeader()
        {

            RuleFor(x => x.LobId).Must(ValidateLOBIDExists);
            RuleFor(x => x.CreatedByUserId).NotEmpty();
            RuleFor(x => x.ProjectManagerId).NotEmpty();
            RuleFor(x => x.ProjectName).NotEmpty();
            RuleFor(x => x.SalesRepId).NotEmpty();
            RuleFor(x => x.DeliveryDate).NotEmpty();
            RuleFor(x => x.ProjectStatusId).NotEmpty();
            RuleFor(x => x.DeptartmentId).NotEmpty();
            RuleFor(x => x.CustomerId).NotEmpty();

            RuleSet("Insert", () =>
            {
                RuleFor(x => x.ProjectLines).Must(ValidateProjectLines).SetCollectionValidator(new ValidProjectLine());
            });
            RuleSet("Update", () =>
            {
                RuleFor(x => x.ProjectLines).SetCollectionValidator(new ValidProjectLine());
            });


        }

我正在嘗試做的是使用 rulset 調用驗證，但我也想在使用 RuleSet 調用驗證時返回“通用”規則。

我調用驗證的代碼如下

public abstract class BaseValidator
    {
        private List<ValidationFailure> _errors;
        public bool IsValid { get; protected set; }
        public List<ValidationFailure> Errors
        {
            get { return _errors; }
            protected set { _errors = value; }
        }
        public virtual bool CallValidation()
        {
            Errors = new List<ValidationFailure>();
            ValidatorAttribute val = this.GetType().GetCustomAttributes(typeof(ValidatorAttribute), true)[0] as ValidatorAttribute;
            IValidator validator = Activator.CreateInstance(val.ValidatorType) as IValidator;
            FluentValidation.Results.ValidationResult result = validator.Validate(this);
            IsValid = result.IsValid;
            Errors = result.Errors.ToList();
            return result.IsValid;
        }

        public virtual bool CallValidation(string ruleSet)
        {
            Errors = new List<ValidationFailure>();
            ValidatorAttribute val = this.GetType().GetCustomAttributes(typeof(ValidatorAttribute), true)[0] as ValidatorAttribute;
            IValidator validator = Activator.CreateInstance(val.ValidatorType) as IValidator;
            FluentValidation.Results.ValidationResult result = validator.Validate(new FluentValidation.ValidationContext(this, new PropertyChain(), new RulesetValidatorSelector(ruleSet)));
            IsValid = result.IsValid;
            Errors = result.Errors.ToList();
            return result.IsValid;
        }

        public BaseValidator()
        {
            Errors = new List<ValidationFailure>();
        }
    }

我可以使用成員ruleSet調用方法CallValidation ，但它也不會調用“通用”規則。

我知道我可以創建一個“通用”規則集來運行這些規則，但在那種情況下，我將不得不始終使用通用規則集調用驗證。

有什么方法可以調用 RuleSet 並調用通用規則。

Answer 1

相反，您可以這樣做：

using FluentValidation;
...
FluentValidation.Results.ValidationResult resultCommon =
    validator.Validate(parameter, ruleSet: "default, Insert");

需要using指令將Validate()擴展方法從DefaultValidatorExtensions引入范圍，該范圍具有ruleSet屬性。 否則，您將只能通過繼承AbstractValidator<T>獲得Validate()方法，它沒有ruleSet參數。

Answer 2

在您的 Validator 類中創建一個方法，其中包括需要始終應用的所有“通用”規則。 現在你可以調用這個方法

• 從您的“創建”規則集中
• 來自規則集之外

例子

public class MyEntityValidator : AbstractValidator<MyEntity>
{
    public MyEntityValidator()
    {
        RuleSet("Create", () =>
            {
                RuleFor(x => x.Email).EmailAddress();
                ExecuteCommonRules();
            });

        ExecuteCommonRules();
    }

    /// <summary>
    /// Rules that should be applied at all times
    /// </summary>
    private void ExecuteCommonRules()
    {
        RuleFor(x => x.Name).NotEmpty();
        RuleFor(x => x.City).NotEmpty();
    }
}

您在控制器中為操作定義規則集

[HttpPost]
public ActionResult Create([CustomizeValidator(RuleSet = "Create")]  MyEntity model)

這將確保對動作 Create 的請求將通過 RuleSet Create 進行驗證。 所有其他操作將使用對控制器中 ExecuteCommonRules 的調用。

Answer 3

我找到了一種方法，通過向CallValidation(string ruleSet)方法添加第二個validator.Validate來實現，如下所示

public virtual bool CallValidation(string ruleSet)
        {
            Errors = new List<ValidationFailure>();
            ValidatorAttribute val = this.GetType().GetCustomAttributes(typeof(ValidatorAttribute), true)[0] as ValidatorAttribute;
            IValidator validator = Activator.CreateInstance(val.ValidatorType) as IValidator;
            FluentValidation.Results.ValidationResult result = validator.Validate(new FluentValidation.ValidationContext(this, new PropertyChain(), new RulesetValidatorSelector(ruleSet)));
            FluentValidation.Results.ValidationResult resultCommon = validator.Validate(this);
            IsValid = (result.IsValid && resultCommon.IsValid);
            Errors = result.Errors.Union(resultCommon.Errors).ToList();
            return IsValid;
        }

Answer 4

我剛剛在下面嘗試過並且有效

   [CustomizeValidator(RuleSet = "default, Create")

Answer 5

    Fluent validation 10+ onwards.
      using FluentValidation;
     var validationResult = await 
     validator.ValidateAsync(account,options=>options("nameOfRuleSet"));
