ASP.NET Core [Require] non-nullable types

由 前提是你 提交于 2020-06-25 02:28:49
问题 Here, the question was posed how to validate non-nullable required types. The provided solution to make the field nullable like the following is not desirable in my case. [Required] public int? Data { get; set; } How can you change the behavior to instead make the following fail validation in the cases where the field is omitted from the request. [Required] public int Data { get; set; } I have tried a custom validator, but these do not have information about the raw value and only see the

How to use a pattern on an input[type=“number”]?

由 守給你的承諾、 提交于 2020-06-23 07:46:29
问题 I want the default value to be 0 and recolor the input if it's more than 0, using :valid . Am I doing something wrong? Is Google Chrome wrong? Or the HTML5 specification? I want to solve this without JS. :valid { background: green } <p>This should not be green, but it is:</p> <input max="100" min="0" pattern="^[1-9]\d*$" type="number" value="0" /> <p>Works perfectly, if the type is changed to text:</p> <input pattern="^[1-9]\d*$" type="text" value="0" /> 回答1: Citing MDN on the pattern

Angular2 Custom Form Validators losing access to `this` in class

由 青春壹個敷衍的年華 提交于 2020-06-22 13:30:11
问题 I'm building an Angular 2 application (2.0) and I've got a form that makes use of the ReactiveForms module. As such, I'm using validator functions on the input fields, including custom validators. This works fine. My issue is that I am also trying to use a custom AsyncValidator on a form field. It seems straight forward enough, but I can never reference properties inside the class from within the AsyncValidator method. The FormGroup and the FormControl properties for the form itself and the

Spring Boot - Validations stopped working after upgrade from 2.2.5 to 2.3.0

问题 I've migrated a Spring Boot project from 2.2.5 to 2.3.0 and after that, Validations stopped to work (they aren't invoked at all). I read in changelog documentation (https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-2.3.0-M1-Release-Notes), that spring-boot-starter-validation now needs to be added manually as a dependency. So, I added it to my pom.xml: <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-validation</artifactId> </dependency> My

Spring boot @Valid on requestBody in controller method not working

由 六眼飞鱼酱① 提交于 2020-06-17 09:32:29
问题 I am trying to validate a simple request body annotated by @Valid annotation in a @RestController annotated by @Validated.

Person class: import javax.validation.constraints.Min import javax.validation.constraints.NotBlank class Person ( @NotBlank
