#Simple Authentication with Bcrypt

This tutorial is for adding authentication to a vanilla Ruby on Rails app using Bcrypt and has_secure_password.

The steps below are based on Ryan Bates's approach from Railscast #250 Authentication from Scratch (revised).

You can see the final source code here: repo. I began with a stock rails app using rails new gif_vault

Proposal for Improving Mass Assignment

For a while, I have felt that the following is the correct way to improve the mass assignment problem without increasing the burden on new users. Now that the problem with the Rails default has been brought up again, it's a good time to revisit it.

Sign Allowed Fields

When creating a form with form_for, include a signed token including all of the fields that were created at form creation time. Only these fields are allowed.

To allow new known fields to be added via JS, we could add:

dhh

class PostsController < ActionController::Base
  def create
    Post.create(post_params)
  end
  
  def update
    Post.find(params[:id]).update_attributes!(post_params)
  end

//How to validate selectize.js comboboxes with the jQuery validation plugin
//selectize.js: http://brianreavis.github.io/selectize.js/ (brianreavis/selectize.js)
//http://jqueryvalidation.org (jzaefferer/jquery-validation)

//configure jquery validation
$("#commentForm").validate({
	//the default ignore selector is ':hidden', the following selectors restore the default behaviour when using selectize.js
	//:hidden:not([class~=selectized]) | selects all hidden elements, but not the original selects/inputs hidden by selectize
	//:hidden > .selectized | to restore the behaviour of the default selector, the original selects/inputs are only validated if their parent is visible
	//.selectize-control .selectize-input input | this rule is not really necessary, but ensures that the temporary inputs created by selectize on the fly are never validated
