waterline-params is designed to give you rails-like parameter helpers to secure your models.

Based on mongoose-params by Bradyn Poulsen.

Installation

Synopsis

var Waterline = require('waterline');

var User = Waterline.Collection.extend({
  attributes: {
    name: {
      type: 'string'
    },
    email: {
      type: 'string',
      required: true
    },
    password: {
      type: 'string',
      required: true
    }
  }
});

require('waterline-params')(User, {
  permitted: 'name email'
});

Methods

#only(params)

Return only params properties for the document

console.log(bob.only('name', 'email')); // {name: 'Bob', email: 'bob@example.com'}

#except(params)

Return all properties except params for the document

console.log(bob.except('password')); // {name: 'Bob', email: 'bob@example.com'}

#assign(data, [override])

Filter and apply changes to the document

bob.assign({
  name: 'Bob Perry',
  password: 'new password'
});
console.log(bob); // {name: 'Bob Perry', email: 'bob@example.com', password: 'still the old password'}

#merge(data, [override])

Same as #assign but returns a copy of the document that the changes were made to

#safeUpdate(data, [override], [done])

Update the document using only permitted properties. Use override to set properties not in permitted.

bob.safeUpdate({
  email: 'bob@newEmail.com',
  password: 'new password'
},function(err, updatedBob){
  console.log(updatedBob); // {name: 'Bob', email: 'bob@newEmail.com', password: 'still the old password'}
});

Static Methods

#only(object, [callback], [thisArg])

See Lodash: _.pick.

#except(object, [callback], [thisArg])

See Lodash: _.omit.

#safeCreate(data, [override], [done])

Create document(s) using only permitted properties. Use override to set properties not in permitted.

user.safeCreate({
  name: 'Bob',
  email: 'bob@example.com',
  password: 'this password'
}, function(err, bob){
  console.log(err); // Error: `password` cannot be blank
});

// versus

user.safeCreate({
  name: 'Bob',
  email: 'bob@example.com'
}, {
  password: 'this password'
}, function(err, bob){
  console.log(bob); // {name: 'Bob', email: 'bob@example.com', password: 'this password'}
});

Configuration

permitted: {String|Array<String>}

String or Array<String> that contains the permitted parameters

These both give the same result:

var params = require('waterline-params');

params(Thing, {
  permitted: 'title description details'
});

params(Thing, {
  permitted: ['title', 'description', 'details']
});
