Beyo Model Validation

Data validation for beyo models.

Features

• Asynchronous model validation
• Integrates automatically with beyo models

Install

npm install beyo-model-validation --save

Usage

Just require beyo-model-validation before defining a new model. Requiring this module is only needed once; not required when defining subsequent models.

var Validation = require('beyo-model-validation').Validation;
var optionsUtils = require('beyo-model-validation').utils.options;
var Model = require('beyo-model');

Validation.define('passwordStrength', function * (model, propertyName, options, translator, next) {
  var allowSpecial = optionsUtil.getBoolean(options, 'allowSpecial', true);
  var allowWhitespace = optionsUtil.getBoolean(options, 'allowWhitespace', false);

  if (/* model._data[propertyName] is valid ? */) {
    return yield next;
  } else {
    return 'Password strength failed';
  }
});

var Foo = Model.define('Foo', {
  'attributes': {
    'id': {
      type: 'int',
      primary: true,
      validation: {
        notEmpty: true,
        unique: true
      }
     },
    'user': {
      type: 'string',
      validation: {
        notEmpty: true,
        email: true
      }
     },
    'pass': {
      type: 'string',
      validation: {
        notEmpty: true,
        minLength: 6,
        maxLength: 24,
        passwordStrength: ['lowercase', 'uppercase', 'digit', 'special']
      }
     },
    'active': {
      type: 'boolean',
      default: true
    }
  }
});

var foo = new Foo({ id: 1, user: 'Bob', pass: '1234' });

console.log(yield foo.validate());
// { "user": "Invalid email address",
//   "pass": "String must contain at least 6 characters"
// }

NOTE: the order of the declared validation chain is important; validators will be executed in the same order.

NOTE: model.validate() returns false if all validation passes. This is to facilitate checks like var errors = model.validate(); if (errors) { ... }.

Available validators

• blacklist : the field's value must not be one of the specified disallowed values.
• decimal : the field's value must be decimal (numeric, not integer).
• integer : the field's value must be an integer (numeric, not decimal).
• hasValue : the field must contain a value (must not be null or undefined)
• match : the field's value must match the given regular expression.
• maxLength : the string-type field's value must not contain more characters than the given value.
• minLength : the string-type field's value must not contain less characters than the given value.
• number : the field's value must be a valid number (may be integer or decimal).
• required : the field is defined with any value.
• unique : the field's value is unique in the dataset. This validation is async and query the database schema.
