FluentValidation Call RuleSet and Common Rules

Question

I have the following class

public class ValidProjectHeader : AbstractValidator
    {
        public ValidProjectHeader()
        {         


        

Answer 1

In your Validator class create a method, that includes all "common" rules that need to be applied at all times. Now you can call this method

• from your "create" RuleSet
• from outside of the RuleSet

Example

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

        ExecuteCommonRules();
    }

    /// 

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

You define the RuleSet for an action in your controller

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

This will insure that requests to action Create will be validated with the RuleSet Create. All other action will use the call to ExecuteCommonRules in controller.
