I'm currently utilizing express-validator and I'm looking to implement varying checks based on a value in the request body.
Although I've created a function for this purpose, it seems that I'm not receiving any responses back from express:
validation/profile.js
module.exports = function (req,res,next) {
if (req.body.type == 'teacher') {
return check('name').exists().withMessage('Name is required'),
} else {
return check('student_id').exists().withMessage('Student id is required'),
}
}
app.js
router.put('/', require('./validation/profile'), (req, res, next) => {
const errors = validationResult(req).formatWith(errorFormatter)
if (!errors.isEmpty()) {
return res.status(422).json({ errors: errors.mapped() })
} else {
res.send(req.user)
}
})
However, when I write the function as a standard function instead of middleware with three params and call it, everything works. The downside is that I lose access to the request object. In this case, I have to hard-code the params.
validation/profile.js
module.exports = function (type) {
if (type == 'teacher') {
return check('name').exists().withMessage('Name is required'),
} else {
return check('student_id').exists().withMessage('Student id is required'),
}
}
app.js
router.put('/', require('./validation/profile')('teacher'), (req, res, next) => {
const errors = validationResult(req).formatWith(errorFormatter)
if (!errors.isEmpty()) {
return res.status(422).json({ errors: errors.mapped() })
} else {
res.send(req.user)
}
})
Any recommendations on how I can achieve different validation checks based on the request body's value?
