[英]Have FluentValidation call a function with multiple parameters
I am using FluentValidation for the server side validation.我正在使用 FluentValidation 进行服务器端验证。 Now I have had it call a function before with Must validation:现在我已经让它在必须验证之前调用了一个函数:
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.现在,这是可行的,因为validateProfile 采用的唯一参数是UserProfile。 it is all good.一切都很好。
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:我现在的问题是我试图让一个带有两个参数的函数验证数据。我试图用于验证的函数如下所示:
bool IsValid(string promocode, IUserProfile userProfile)
Now, I am not sure how to bind IsValid to a fluentValidation.现在,我不确定如何将 IsValid 绑定到 fluentValidation。 Any ideas?有任何想法吗?
Where is promocode coming from?促销代码从何而来? The Must method has overloads accepting Func<TProp,bool>
, Func<T,TProp,bool>
, and Func<T,TProp, PropertyValidatorContext, bool>
Must 方法具有接受Func<TProp,bool>
、 Func<T,TProp,bool>
和Func<T,TProp, PropertyValidatorContext, bool>
If promocode is a property of the object being validated, it would be easy to pass something like如果 promocode 是被验证对象的属性,则很容易传递类似
.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();
}
