BeSwarm.Validator 1.0.0-rc1

Validator

Perform recursive localized DataAnnotations Attribute validation on your models and fluent validations.

Provide BlazorValidator for Blazor apps.

DataAnnotation Attribute validated

• [Required]
• [Range]
• [MaxLength]
• [MinLength]
• [StringLength]

Sample usage

public class Model
{
    [Required]
    [MaxLength(6)]
    public string Name { get; set; }
}

class Program
{


    public static async Task Main(string[] args)
    {

        Model t= new();
        ValidateContext context = new ValidateContext(false);
        var listvalidationfailure = await Validate.ValidateObject(t, context);

        foreach (var item in listvalidationfailure)
        {
           Console.WriteLine($"*** error **** Field: {item.PropertyName} value={item.Obj} attribute:{item.AttributeType} message:{item.ErrorMessage}");
        }
        t.Name = "11";
        listvalidationfailure = await Validate.ValidateObject(t, context);
        foreach (var item in listvalidationfailure)
        {
            Console.WriteLine($"*** error **** Field: {item.PropertyName} value={item.Obj} attribute:{item.AttributeType} message:{item.ErrorMessage}");
        }
        t.Name = "LPLOKUAAA";
        listvalidationfailure = await Validate.ValidateObject(t, context);
        foreach (var item in listvalidationfailure)
        {
            Console.WriteLine($"*** error **** Field: {item.PropertyName} value={item.Obj} attribute:{item.AttributeType} message:{item.ErrorMessage}");
        }
		Console.ReadKey();
    }
}

Get attribute on property if exist

ex: check if [Required] is present on a property

   RequiredAttribute? ra=Validate.GetAttributeIfExist<RequiredAttribute>(t, nameof(t.Name));

Using with blazor

<EditForm Model="@_model" OnValidSubmit="@SubmitValidForm">
	<BeSwarm.Validator.BlazorValidator @ref="_BlazorValidationValidator" ValidateContext="mycontext" />

Add Fluent validation

Create au fluent class

 public class FluentValidatorModel : AbstractValidator<Model>
 {
	public FluentValidatorModel()
	{
			RuleFor(x => x.Name).NotEmpty().WithMessage("controlled by fluent: not empty");
	}
 }

 // add fluent validator
 FluentValidatorModel fv = new();
 context.FluentValidator = fv;
 listvalidationfailure = await Validate.ValidateObject(t, context);
 foreach (var item in listvalidationfailure)
 {
   Console.WriteLine($"*** error **** Field: {item.PropertyName} value={item.Obj} attribute:{item.AttributeType} message:{item.ErrorMessage}");
 }

you can also add a Fluent validation strategy

public class FluentValidatorModel : AbstractValidator<Model>
{
	public FluentValidatorModel()
	{
		RuleSet("FilterName", () =>
		{
			RuleFor(x => x.Name).NotEmpty().WithMessage("controlled by fluent: not empty");
		});
	}
}
Action<ValidationStrategy<object>> strategy = new(options => options.IncludeRuleSets("FilterName"));
context.FluentStrategy = strategy;
