Pondhawk.Rules.EFCore

Pre-save entity validation interceptor for EF Core powered by the Pondhawk.Rules engine. Validates all Added and Modified entities through your rule set before they reach the database.

Quick Start

Configure Validation

using Pondhawk.Rules.EFCore;
using Pondhawk.Rules.Factory;

// Define validation rules
var ruleSet = new RuleSet();

ruleSet.AddValidation<Order>("total-positive")
    .Assert<decimal>(o => o.Total)
    .IsGreaterThan(0m);

ruleSet.AddValidation<Order>("items-required")
    .AssertOver<OrderItem>(o => o.Items)
    .IsNotEmpty();

// Wire into DbContext
var options = new DbContextOptionsBuilder<AppContext>()
    .UseSqlServer(connectionString)
    .AddRuleValidation(ruleSet)
    .Options;

Automatic SaveChanges Validation

var context = new AppContext(options);

var order = new Order { Total = 100m, Items = [new OrderItem()] };
context.Orders.Add(order);

await context.SaveChangesAsync();
// Interceptor validates all Added/Modified entities
// Throws EntityValidationException if violations exist

Handle Validation Failures

try
{
    await context.SaveChangesAsync();
}
catch (EntityValidationException ex)
{
    var violations = ex.ValidationResult.Violations;
    // violations contains the structured RuleEvent violations
}

How It Works

  • RuleValidationInterceptor extends SaveChangesInterceptor.
  • On SavingChanges/SavingChangesAsync, it pulls all Added and Modified entities from ChangeTracker.
  • Each entity is validated through IRuleSet.Validate().
  • If any entity fails validation, EntityValidationException is thrown before the save reaches the database.
