如何使用 Joi 验证实现正确的参考逻辑？

Question

I'm trying to create a simple schema that will check to make sure that a number range is correctly inputted. Logic is that start must be less than end and end must be greater than start .

Here is my schema;

const start = Joi.number().less(Joi.ref('end'))
const end = Joi.number().greater(Joi.ref('start'))
//age Range object
const ageRange = Joi.object().keys({
  start: start,
  end: end,
})

The error I'm getting while the code is compiling: Error: item added into group end created a dependencies error

I've tried changing the logic but I'm not sure what other structure would work. I get that It's possibly an issue with the reference logic so any alternative suggestion to this would be greatly appreciated.

Answer 1

start must be less than end and end must be greater than start I think you can just check one of them, the other one is true automatically. not sure what the terms was in Mathematics.

something like this should work

 const schema = { start: Joi.date().iso().required(), end : Joi.date().iso().greater(Joi.ref('start')).required() }; let ageRange = Joi.object().keys(schema);
