title: rails 4 password confirmation ca
body: <p>I'm going through one of the Rails tutorials, during a section on user validations, I keep getting an error telling me my password confirmations can't be blank when editing/creating a user.  I looked through previous answers and it looks like people used attr_accessible, which was pulled out of rails.  I'm a total rails/web dev newb so I'm not sure how to proceed.  The view is in HAML, sorry if that's bad practice.</p>
  
  <p><strong>Model</strong></p>
  
  <pre><code>class User &lt; ActiveRecord::Base
  
    before_save { self.email = email.downcase }
    attr_accessor :name, :email
    validates_confirmation_of :password
    has_secure_password
  
  
    validates :name, presence: true, length:{ maximum: 16 }
  
    VALID_EMAIL_REGEX = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i
  
    validates :email, presence: true, format: { with: VALID_EMAIL_REGEX },
      uniqueness: { case_sensitive: false }
  
    validates :password, length: { minimum: 6 }
  
  
    has_one :profile
    has_many :posts
  
  
    end
  </code></pre>
  
  <p><strong>View</strong></p>
  
  <pre><code>= form_for(@user) do |f|
    - if @user.errors.any?
      #error_explanation

          prohibited this username from being saved:
