Undefined Method attr_accessible

Question

I am somewhat new to rails and I am trying to create a User login. I went through the tutorial found here. At the end it had me add "attr_accessible" for mass assignment. However when I did that I got the following error:

undefined method `attr_accessible' for #<Class:0x007ff70f276010> 

I saw on this post that I neeed < ActiveRecord::Base. But I do have that included. Here is the code for my User Model:

class User < ActiveRecord::Base    attr_accessor :password   EMAIL_REGEX = /\A[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}\z/i   validates :username, :presence => true, :uniqueness => true, :length => { :in => 3..20 }   validates :email, :presence => true, :uniqueness => true, :format => EMAIL_REGEX   validates :password, :confirmation => true #password_confirmation attr   validates_length_of :password, :in => 6..20, :on => :create   before_save :encrypt_password   after_save :clear_password   attr_accessible :username, :email, :password, :password_confirmation    def encrypt_password     if password.present?       self.salt = BCrypt::Engine.generate_salt       self.encrypted_password= BCrypt::Engine.hash_secret(password, salt)     end   end    def clear_password     self.password = nil   end  end 

Any other ideas on what could be causing this problem would be really appreciated, thanks!

Edit: On Rails 4.1. Looks like it doesn't apply anymore. Thanks fotanus

Answer 1

No mass assignment allowed for Rails 4.1

instead of having attr_accessible :username, :email, :password, :password_confirmation in your model, use strong parameters. You'll do this in your UsersController:

    def user_params       params.require(:user).permit(:username, :email, :password, :password_confirmation)     end 

then call the user_params method in your controller actions.
