Type boolean is not supported

[shubhkr]

How to validate boolean type?
{
type: 'boolean',
required: true,
message: 'Some message',
match: '^(true|false)$'
}

Using this gives an error message saying validation failed

[shubhkr]

even if I remove the match it still gives me the error. But if I change the type to string or number and pass the appropriate values It works fine.
Don't know why it is failing for boolean. Is there something I am doing wrong?

What version are you using? Can you post an example? I can't deduce from this what's going on.

[shubhkr]

I am using 3.0.1
Here's an example:

import Schema from 'validate'

const user = new Schema({
  username: {
    type: 'boolean',
    required: true,
    message: 'some message'
  },
})

var obj = {
username: true
}

user.validate(obj)

Your example works just fine

Are you passing in a request body? In that case you're probably passing in a string, not a boolean, which would explain why the validation fails. You can enable typecasting by doing something like:

const user = new Schema({
  username: {
    type: 'boolean',
    required: true,
    message: 'some message'
  }
}, { typecast: true })

Also, version 3.0.1 is quite old. I recommend updating to the latest version.

[shubhkr]

Yup now the same thing is working perfectly fine..

Hi, found the issue.. For true it is working as intended, for false it is failing
https://runkit.com/embed/2ytdqg6p8imj

const Schema = require('validate@3.0.1')

const user = new Schema({
  username: {
    type: 'boolean',
    required: true,
    message: 'some message'
  }
})

var obj = {
  username: false
}

const errors = user.validate(obj)
console.log(errors)

Ah, yes, that is an old bug. You should update to the latest version. It was fixed a while back.

[shubhkr]

Hi when I updated to the latest version, I am getting this error:
[TypeError: Cannot call a class as a function]

[eivindfjeldstad]

That has nothing to do with this lib, though. You have probably forgotten a new somewhere. The stack trace should tell you where

[shubhkr]

Yeah it is working fine now. I had one missing new which I guess is required with the latest version.
And had to add polyfill for Array.includes and Object.entries
