How to make a custom message using joi? i saw many answered question related on this but i dont know why it didnt work on my end, the error message always appeared is "Student" does not contain 1 required value(s) what i want is "Student" This field is required.
export const VALIDATION_SCHEMA = {
students: Joi.array()
.label('Student Name(s)')
.items(
Joi.object({
name: Joi.string(),
value: Joi.string()
}).required().messages('"Student" This field is required.')
),
}
You can return a custom error object using Error constructor like this:
var schema = Joi.object().keys({
firstName: Joi.string().min(4).max(8).required().error(new
Error('error message here for first name')),
lastName: Joi.string().min(5).max(1).required().error(new
Error('error message here for last name'))
});
Joi.validate(req.body, schema, function(err, value) {
if (err) {
console.log(err.message)
return catched(err.message);
}
});
The easiest way in my opinion would be this.
const Joi = require("@hapi/joi");
export const categorySchema = Joi.object({
mobile: Joi.string().trim().regex(/^[6-9]\d{9}$/).required().messages({
"string.base": `"" should be a type of string`,
"string.empty": `"" must contain value`,
"string.pattern.base": `"" must be 10 digit number`,
"any.required": `"" is a required field`
}),
password: Joi.string().trim().required().messages({
"string.base": `"" should be a type of 'text'`,
"string.pattern.base": `"" must be 10 digit number`,
"any.required": `"" is a required field`
}),
}).required();
