fluentvalidation

I setup a web api project to use FluentValidation using the webapi integration package for FluentValidation. Then I created a validator that uses CustomAsync(...) to run queries against the database. The issue is that the validation seems to deadlock when awaiting for the database task. I did some investigation, it seems that the MVC ModelState API is synchronous, and it calls a synchronous Validate(...) method that makes FluentValidation to call task.Result , causing the deadlock. Is it correct to assume that async calls won't work well with webapi integrated validation? And if that is the

Using FluentValidation 4.4, the following rules emit the correct unobtrusive validation data attributes on input fields: RuleFor(e => e.PrimaryContact).NotEmpty(); rendering the following html: <input class="text-box single-line k-textbox input-validation-error" data-val="true" data-val-required="'Primary Contact' should not be empty." id="PrimaryContact" name="PrimaryContact" type="text" value=""> However, a rule with a nested property does not emit any validation data attributes: RuleFor(e => e.Company.Name).NotEmpty(); rendering the following html: <input class="text-box single-line k

I get the validation message "The value xxx is not valid for yyy". It happens when I post incorrect value for double type. I have no idea how to change it. Unfortunately this isn't something that FluentValidation has the ability to override - the extensibility model for MVC's validation is somewhat limited in many places, and I've not been able to find a way to override this particular message. An alternative approach you could use is to define two properties on your view model - one as a string, and one as a nullable double. You would use the string property for MVC binding purposes, and the

Since there is no way to validate a property (with unobtrusive clientside validation) using multiple regex patterns (because validation type has to be unique) i decided to extend FluentValidation so i can do the following. RuleFor(x => x.Name).NotEmpty().WithMessage("Name is required") .Length(3, 20).WithMessage("Name must contain between 3 and 20 characters") .Match(@"^[A-Z]").WithMessage("Name has to start with an uppercase letter") .Match(@"^[a-zA-Z0-9_\-\.]*$").WithMessage("Name can only contain: a-z 0-9 _ - .") .Match(@"[a-z0-9]$").WithMessage("Name has to end with a lowercase letter or

I am trying to automate the validation of my view models, I know I can just add a an attribute to specify my validation but there is an option to set up a factory to automate all that, I looked at: this answer and came up with this using simple injector 3.1: public class CustomValidatorFactory:ValidatorFactoryBase { private readonly Container siContainer; public CustomValidatorFactory(Container siContainer) { var assemblies = AppDomain.CurrentDomain.GetAssemblies().ToList(); this.siContainer = siContainer; this.siContainer.Register(typeof(IValidator<>), assemblies); } public override

I need to be able to provide the IComponentContext to my ValidatorFactory to resolve FluentValidation Validators. I am a little stuck. ValidatorFactory public class ValidatorFactory : ValidatorFactoryBase { private readonly IComponentContext context; public ValidatorFactory(IComponentContext context) { this.context = context; } public override IValidator CreateInstance(Type validatorType) { return context.Resolve(validatorType) as IValidator; } } How do I provide the context and register the ValidatorFactory FluentValidation.Mvc.FluentValidationModelValidatorProvider.Configure(x => x
