How can I check whether an ObjectID is valid using Node's driver
I tried :
var BSON = mongo.BSONPure;
console.log("Validity: " + BSON.ObjectID.isValid('ddsd'))
But I keep getting an exception instead of a true or false. (The exception is just a 'throw e; // process.nextTick error, or 'error' event on first tick'
If you are using mongoose then you can use mongoose for validation rather than depending on any other library.
if (!mongoose.Types.ObjectId.isValid(req.id)) {
return res.status(400).send("Invalid object id");
}
Below is my model where I am trying to validate subject id that is of type objectId data using JOI (Joi.objectId().required()):
const Joi = require('joi');
const mongoose = require('mongoose');
const Category = mongoose.model('Category', new mongoose.Schema({
name: String
}));
function validateCategory(category) {
const schema = {
name: Joi.string().min(5).max(50).required(),
subject_id: Joi.objectId().required(),
};
return Joi.validate(category, schema);
}
exports.Category = Category;
exports.validate = validateCategory;
joi-objectid validates that the value is an alphanumeric string of 24 characters in length.
Follow this regular expression :
in js
new RegExp("^[0-9a-fA-F]{23}$").test("5e79d319ab5bfb2a9ea4239")
in java
Pattern.compile("^[0-9a-fA-F]{23}$").matcher(sanitizeText(value)).matches()
