validation

问题 I am working on an io-ts validation where I would like to validate the list length (it has to be between min and max). I am wondering if there's a way to achieve this behavior since it could come quite handy at runtime for API endpoint validation. What I have so far is interface IMinMaxArray { readonly minMaxArray: unique symbol // use `unique symbol` here to ensure uniqueness across modules / packages } const minMaxArray = (min: number, max: number) => t.brand( t.array, (n: Array): n is t

问题 This is my first post. I need string array validation such like below. [Required(ErrorMessage = "Content name is required")] public string[] ContentName { get; set; } I found a post which has the same situation. This answer and following code helped me so much and I could solve my problem. public class StringArrayRequiredAttribute : ValidationAttribute { protected override ValidationResult IsValid (object value, ValidationContext validationContext) { string[] array = value as string[]; if

问题 Dear Spring Community, I am building my project using Spring. In my API layer, I am leveraging the Validator interface in order to do some custom validation and set an error. @Override public void validate(Object obj, Errors e) { SignUpRequest signUpRequest = (SignUpRequest) obj; User user = userService.getUserByEmail(signUpRequest.getEmail()); if (user != null) { e.rejectValue("user", ErrorCodes.USER_EXIST, "user already exist"); } } Now, in my API signature, since I am using the

问题 I'm using Yup.js to validate some form fields. I have two integer fields, Year Built & Year Renovated . Year Built is a required field, Year Renovated is not. Year renovated can be left blank, however if there is a value it should be larger than year built (for a renovation certainly must occur after the date it was built). I believe I need to use yup's ref() as well as yup's when() function. I've tried the following: let currentYear = new Date().getFullYear(); yup.object().shape({ yearBuilt

问题 What would the method facesContext.isValidationFailed() return after the Render Response Phase when the validation fails? It returns false for me in this case. 回答1: It will only return true when FacesContext#validationFailed() has been called by the JSF validation internals or by your own code as follows: FacesContext.getCurrentInstance().validationFailed(); As far JSF internal code is concerned, only UIInput#processValidators() and UIViewParameter#processValidators() will implicitly call

问题 I've been searching for a solution for days now and since there is no forum at Apache Jena I had to create an account at stackoverflow to ask. My problem is that I need a temporary (deep) copy of an already loaded ontology, namely an object of OntModelImpl (with some imports but without any attached inference machine). Its purpose is to apply some validation steps on the model which require some SPARQL UPDATE queries to add some automatically generated triples first. These additional triples

问题 Can someone tell me why the following css is not validating? I've been trying to research this myself with no luck. All of the documentation I've read says this is the proper why to do gradients in css3. #header { color: white; font-size: 12px; font-family: Helvetica, Verdana, Arial, sans-serif; background: black; background: -moz-linear-gradient(top, rgba(0,0,0,0.65) 0%, rgba(0,0,0,0) 100%); background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,rgba(0,0,0,0.65)), color
