[英]How to use Joi alternatives conditional for schema validation?
I have a use case where a schema field is mandatory depending on the value of another field,我有一个用例,其中模式字段是强制性的,具体取决于另一个字段的值,
eg.例如。 If the schema has 2 fields, name and addr,
如果模式有 2 个字段,name 和 addr,
if the value of name field is "test" only then addr field is required.如果 name 字段的值为“test”,则 addr 字段是必需的。
I am using Joi for object validation,我正在使用 Joi 进行 object 验证,
Following is my sample code -以下是我的示例代码 -
const Joi = require('joi');
let test = async() => {
const schema = Joi.object({
name: Joi.string().required(),
addr: Joi.alternatives().conditional('name', {is: 'test', then: Joi.string().required()})
});
const request = {
name: "test"
}
// schema options
const options = {
abortEarly: false, // include all errors
allowUnknown: true, // ignore unknown props
stripUnknown: true // remove unknown props
};
// validate request body against schema
const validationResponse = await schema.validate(request, options);
console.log("validationResponse => ", validationResponse);
return true;
};
test();
current output - validationResponse => { value: { name: 'test' } }
当前 output -
validationResponse => { value: { name: 'test' } }
what I'm expecting is validationResponse to have error message that addr field is missing.我期望的是 validationResponse 有错误消息,指出地址字段丢失。
