Mongoose Boolean validation not useful if a String is provided
Here is a solution that borders on hackery, but it should work:
const mongoose = require('mongoose');mongoose.Schema.Types.Boolean.convertToFalse = new Set([false]);mongoose.Schema.Types.Boolean.convertToTrue = new Set([true]);Remember to set these immediately after the first require, and keep an eye on the cache.
Relevant documentation:https://mongoosejs.com/docs/schematypes.html#booleans
Turns our Mongoose casts five different things to bool, even with strict schemas. Really grinds my gears.
you can change type Boolean to String and validate like that
testField: { type : String, required: true, validate: { validator: function (value) { return value === "true" }, message: 'Field must be true' } }
