Question

I am trying to expand the devise registration form to allow a new user to create an organization (company) at the same time they sign up. I finally got the nested form fields visible (after reading several SO threads), but I have encountered an error that I believe to be associated with mass assignment.

I am a complete rails noob, still getting my feet wet. Other SO questions have gotten me this far, but now I am just stuck.

Here are my current files:

User Model:

class User < ActiveRecord::Base

  belongs_to :organization
  accepts_nested_attributes_for :organization

  validates_presence_of :first_name, :last_name
  validates_length_of :first_name, :maximum => 50
  validates_length_of :last_name, :maximum => 50

  # Include default devise modules. Others available are:
  # :token_authenticatable, :encryptable, :confirmable, :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable,
     :recoverable, :rememberable, :trackable, :validatable

  # Setup accessible (or protected) attributes for your model
  attr_accessible :email, :password, :first_name, :last_name, :password_confirmation, :remember_me, :organization_attributes, :organization

end 

Organization Model

class Organization < ActiveRecord::Base

  has_many :users, :foreign_key => "user_id"
  accepts_nested_attributes_for :users

end

Registration Form

<h2>Register for a new account</h2>

<% resource.build_organization %>

I am sure I am missing something simple. Looking forward to seeing what it is 😉

try this:

 
       f.fields_for :organization_attributes, resource.organization do |fo|
