Question

I’m trying to add the field "name" to Devise, but when I sign up a new user it breaks when I push submit.

I’ve made sure to run rake db:migrate and I’ve restarted my server, but I get this error:

ActiveRecord::StatementInvalid in Devise::RegistrationsController#create

NoMethodError: undefined method `name’ for nil:NilClass: INSERT INTO
“users” (“created_at”, “current_sign_in_at”, “current_sign_in_ip”,
“email”, “encrypted_password”, “last_sign_in_at”, “last_sign_in_ip”,
“name”, “pic_file_name”, “remember_created_at”,
“reset_password_sent_at”, “reset_password_token”, “sign_in_count”,
“title”, “updated_at”) VALUES ($1, $2, $3, $4, $5, $6, $7, $8, $9,
$10, $11, $12, $13, $14, $15) RETURNING “id”

User Class

  class User < ActiveRecord::Base
  has_and_belongs_to_many :roles

    devise :database_authenticatable, :registerable,
     :recoverable, :rememberable, :trackable, :validatable

    attr_accessible :email, :password, :password_confirmation, :remember_me, :role_ids, :name, :title, :pic_file_name
    has_one :picture, :dependent => :destroy
    accepts_nested_attributes_for :picture, :allow_destroy => true
    has_many :comments, :dependent => :destroy
    has_many :discussions, :dependent => :destroy



    def role?(role)
      roles.map(&:name).include? role.to_s
    end

  end

schema

  create_table "users", :force => true do |t|
t.string   "email",                  :default => "", :null => false

Answer 1

Put name after attr_accessible: in user class.
