Mongoose Validator All

A wrapper for the mongoose plugin mongoose-validator, which itself wraps validator.js, to provide schema validation.

This plugin supports all of the mongoose-validator functionality (by passing them through) but also provides an additional method called multiValidate. This forces mongoose to test every validation rule, instead of stopping at the first fail on a field.

For more information, please check mongoose-validator. This README will only highlight the additional functionality that this plugin wrapper adds.

Installation

$ npm install mongoose-validator-all --save

Usage

var mongoose = require('mongoose');
var validate = require('mongoose-validator-all');

var rules = {
  name: validate.multiValidate([
    {
      validator: 'isLength',
      arguments: [3, 50],
      message: 'Name should be between {ARGS[0]} and {ARGS[1]} characters'
    }, {
      validator: 'isAlphanumeric',
      passIfEmpty: true,
      message: 'Name should contain alpha-numeric characters only'
    }
  ])
};

var UserSchema = new mongoose.Schema({
  name: {type: String, required: true, validate: rules.name}
});

var User = mongoose.model('User', UserSchema);

Error objects are returned as normal via Mongoose. With the exception being that multiValidate returns an array of messages per document property validation error, instead of a single string.

Example of error returned

var User = mongoose.model('User');

var user = new User({name: '_a'});

user.save(function(error) {
  console.log(error.errors.name.message);
  /*
    This will show an array of messages,
    unlike the normal single string for the first validation fail
  */
  console.log('%d validation errors against name.', error.errors.name.message.length);

  // Errors can easily be joined if a single string is required
  console.log(error.errors.name.message.join(' '));
});

See mongoose issue #2612 for further information.

Contributors

Majority of thanks goes to Lee Powell for the mongoose-validator plugin this is all based off. Also the code from mongoose-validate-all by szdc.

Quote from the mongoose-validator readme:

Special thanks to Francesco Pasqua for heavily refactoring the code into something far more future proof. Thanks also go to Igor Escobar and Todd Bluhm for their contributions.
