Ruby Error with in the Regex
require 'digest' #for password hasing
class User < ActiveRecord::Base
#It tells Ruby to create reader and writer methods for password. Because the password
#column doesn’t exist in your table anymore, a password method isn’t created automatically
#by Active Record. Still, you need a way to set the password before it’s encrypted, so you make
#your own attribute to use. This works like any model attribute, except that it isn’t persisted to
#the database when the model is saved.
attr_accessor :password

This is how my altered DeviseCreate migration looks like
class DeviseCreateUsers < ActiveRecord::Migration
def change
create_table(:users) do |t|
## Database authenticatable
t.string :email, :null => false, :default => ""
t.string :encrypted_password, :null => false, :default => ""
## Rememberable
t.datetime :remember_created_at

I fixed my problem. But I was wondering if it's possible to create a table like this (see:: second gist - original).. Cause there is an add_index: email but there is no t.string :email, in the Do Block
#This is my file altered... the one that works for me
class DeviseCreateUsers < ActiveRecord::Migration
def change
create_table(:users) do |t|
## Database authenticatable
t.string :email, :null => false, :default => ""
t.string :encrypted_password, :null => false, :default => ""
## Rememberable
t.datetime :remember_created_at

Wrong javascript output. I'm trying to load a form using Javascript. So that when I user click on "new Comment" it will append the 'comment form' but when I clicked on the link it renders $("<form accept-charset=\"UTF-8\" action=\"/articles/3/comments\"...
$("<%= escape_javascript render(:file => 'comments/new.html.erb') %>").insertAfter('#comments');
$('#new_comment_link').hide();
