RuleSet 中的 FluentValidation 验证器未执行

Question

I have a validator with a ruleset

public class ApplicationValidator : AbstractValidator<Application>
{
    public ApplicationValidator()
    {
        RuleSet("CreateApplication", () =>
        {
            RuleFor(a => a.SalesChannelBroker)
                .SetValidator(new BrokerActiveRule());

            RuleFor(ld => ld.LoanDetailSegment)
                .SetValidator(new ProductCodeValidRule());
        });
    }
}

However the rules are not validated when I execute validation as follows, why?

// Validate
var validationResult = new ApplicationValidator().Validate(app, ruleSet: "CreateApplication");

What do your BrokerActiveRule and ProductCodeValidRule validators look like? Are the rule/s defined in them within the CreateApplication rule set?

If they are not within a rule set, or in a rule set other than CreateApplication , they won't be invoked.

The child validator behaviour I still find a bit weird, but basically if you invoke a parent validator with a rule set, and you want your child validators to be invoked, the inclusion ( SetValidator in this case) must be within the rule set, and the child validator rules you want to apply must also be within that rule set.

See this for more info.

This behaviour can be customized by creating your own IValidatorSelector . This was something that I was looking into doing (but haven't got round to yet) as I have a case where the child validator has default and rule set specific rules meaning I had to include the child validator twice in the parent validator.
