JAAvila.FluentOperations.DataAnnotations

Automatically generates JAAvila.FluentOperations Quality Blueprint validation rules from System.ComponentModel.DataAnnotations attributes.

Installation

dotnet add package JAAvila.FluentOperations.DataAnnotations

Quick Start

Fully automatic blueprint

var blueprint = DataAnnotationsBlueprint<User>.FromAnnotations();
var report = blueprint.Check(user);

if (!report.IsValid)
{
    foreach (var failure in report.Failures)
        Console.WriteLine(failure);
}

Hybrid blueprint — annotations + custom rules

public class UserBlueprint : DataAnnotationsBlueprint<User>
{
    public UserBlueprint()
    {
        using (Define())
        {
            // All [Required], [EmailAddress], etc. rules are generated automatically:
            IncludeAnnotations();

            // Add extra rules that have no DataAnnotation equivalent:
            For(x => x.Username).Test().NotBeNull().HaveMinLength(3).HaveMaxLength(20);
        }
    }
}

Dependency Injection

// Program.cs / Startup.cs
services.AddDataAnnotationsBlueprint<User>();

// Inject and use:
public class UserService(DataAnnotationsBlueprint<User> blueprint)
{
    public void Validate(User user)
    {
        var report = blueprint.Check(user);
        // ...
    }
}

Attribute Mapping Table

DataAnnotations Attribute Generated Operation
[Required] on string .NotBeNull().NotBeEmpty()
[Required] on other types .NotBeNull()
[StringLength(max)] .HaveMaxLength(max)
[StringLength(max, MinimumLength = min)] .HaveLengthBetween(min, max)
[MinLength(n)] .HaveMinLength(n)
[MaxLength(n)] .HaveMaxLength(n)
[Range(min, max)] .BeInRange(min, max)
[EmailAddress] .BeEmail()
[Url] .BeUrl()
[RegularExpression(pattern)] .Match(pattern)
[Phone] .Match(phoneRegex)
[CreditCard] .BeCreditCard()

Supported property types for [Range]: int, int?, long, long?, double, double?, decimal, decimal?.

AnnotationOptions

var options = new AnnotationOptions
{
    DefaultSeverity = Severity.Warning,          // Default: Severity.Error
    ErrorCodePrefix = "USER",                    // Default: null (no error code)
    IgnoreRequired = true,                       // Default: false
    UseAnnotationErrorMessages = false,          // Default: true
    ExcludedProperties = { "InternalId" },       // Default: empty
    IncludeInheritedProperties = false           // Default: true
};

var blueprint = DataAnnotationsBlueprint<User>.FromAnnotations(options);
