I am using FluentValidation for the server side validation. Now I have had it call a function before with Must validation:
RuleFor(x => x.UserProfile).Must(ValidateProfile).WithMessage("We are sorry, you have already logged on " + DateTime.Now + ". Please come again tomorrow.");
Now, that works because the only parameter that validateProfile takes is UserProfile. it is all good.
My problem now is that I am trying to have a function with two parameters validate the data.The function which I am trying to use for validation looks like below:
bool IsValid(string promocode, IUserProfile userProfile)
Now, I am not sure how to bind IsValid to a fluentValidation. Any ideas?
Where is promocode coming from? The Must method has overloads accepting Func<TProp,bool>
, Func<T,TProp,bool>
, and Func<T,TProp, PropertyValidatorContext, bool>
If promocode is a property of the object being validated, it would be easy to pass something like
.RuleFor(x => x.UserProfile).Must( (o, userProfile) => { return IsValid(o.promoCode, userProfile); })
//with MustAsync
RuleFor(v => v.UserId).MustAsync(
async (model, userId, cancellation) =>
{
return await IsValid(model.PromoCode, userId, cancellation);
}
).WithMessage("{PropertyName} message.");
private async Task<bool> IsUniqueUserNameAsync(string promoCode, string userId, CancellationToken cancellationToken)
{
throw new NotImplementedException();
}
