ruby on rails - unknown attribute with devise -


for data model, have 2 different types: family members , friends. plan have each have foreign key user table, created devise. so, when user signs up, want them either go /friends/sign_up or family_members/sign_up . so, friend class is

class friend < activerecord::base   belongs_to :label   belongs_to :user   belongs_to :gender   belongs_to :location   belongs_to :orientation   belongs_to :matchmaker    def after_initialize     self.build_user if self.user.nil?   end   #accepts_nested_attributes_for :user   delegate :username, :to => :user   delegate :email, :to => :user   delegate :password, :to => :user   delegate :password_confirmation, :to => :user   delegate :rememebr_me, :to => :user    # include default devise modules. others available are:   # :token_authenticatable, :encryptable, :confirmable, :lockable, :timeoutable , :omniauthable   devise :database_authenticatable, :registerable,          :recoverable, :rememberable, :trackable, :validatable   # setup accessible (or protected) attributes model   attr_accessible :username, :email,  :password, :password_confirmation, :remember_me end

and user class is

class user < activerecord::base   # include default devise modules. others available are:   # :token_authenticatable, :encryptable,     :confirmable, :lockable, :timeoutable , :omniauthable #  devise :database_authenticatable, :registerable, #         :recoverable, :rememberable, :trackable, :validatable    attr_accessor :username, :email,    :password, :password_confirmation,   :remember_me   # setup accessible (or protected) attributes model   attr_accessible :username, :email,   :password, :password_confirmation, :remember_me end

i'm using formtastic view. right now, i'm getting 

unknown attribute: username

with parameters

{"utf8"=>"✓", "authenticity_token"=>"8scsjebucwnflarqkp9msbuaaqfzqkazbxotlynwnym=", "friend"=>{"username"=>"aaaa", "email"=>"aaa@aaa.com", "password"=>"[filtered]", "password_confirmation"=>"[filtered]"}, "commit"=>"create friend"}

right now, i'm randomly trying add nested_attributes , whatever 2 models. use table inhertence, i'd prefer not (unless can add foreign key subclassses pointing @ superclass, fine).

ok, i've fixed problem satisfaction. here new code future reference:

class friend < activerecord::base    belongs_to :friend_user, :class_name =>  end  class frienduser < user   set_table_name :users   has_one :friend end class user < activerecord::base   # include default devise modules. others available are:   # :token_authenticatable, :encryptable,  :confirmable, :lockable, :timeoutable , :omniauthable   devise :database_authenticatable, :registerable,          :recoverable, :rememberable, :trackable, :validatable    # setup accessible (or protected) attributes model   attr_accessible :username, :email,     :password, :password_confirmation, :remember_me end
