Devise: custom fields not saved after signing up

问题

Environment: Rails 4, Devise 3.2.2
Given I added two fields (name, profession) to my devise model.
When I sign up
Then I see in the database the new columns not affected.

Below are my controller and model classes

#custom controller
class UsersController < Devise::RegistrationsController
  before_action :configure_permitted_parameters

  #devise's controller extensions

  protected

  def configure_permitted_parameters
     devise_parameter_sanitizer.for(:sign_up) do |u|
       u.permit(:name, :email, :profession, :password, :password_confirmation)
     end
  end
end

#Devise Model
class User < ActiveRecord::Base
   devise :database_authenticatable, :registerable,
          :recoverable, :rememberable, :trackable, :validatable
   attr_accessor :name, :profession
   validates :name, presence: true
   validates_uniqueness_of  :email, :name
end

I specify that devise runs correctly and uses my custom controller.
I also checked in the params hash and it includes the new field values as you can see:

Processing by UsersController#create as HTML
  Parameters: {"utf8"=>"✓",  "authenticity_token"=>"F3AjMd1/EpYvuhckEMPUkiMZ1szHa6ba7OMbjjSltOk=", "user"=>{"name"=>"test", "email"=>"you@contect.com", "profession"=>"prof", "password"=>"[FILTERED]", "password_confirmation"=>"[FILTERED]"}, "commit"=>"Save"}

And below is the generated sql:

INSERT INTO "users" ("created_at", "email", "encrypted_password", "updated_at") VALUES  (?, ?, ?, ?)  [["created_at", Tue, 11 Feb 2014 15:14:56 UTC +00:00], ["email", "you@contect.com"], ["encrypted_password", "$2a$10$Bn3LIldBUDPHKO0vrXd7peVz6q/42hOrCOcqdbvBMHVeEtn4EfKma"], ["updated_at", Tue, 11 Feb 2014 15:14:56 UTC +00:00]]

which contains none of new fields added.

Any hint will be welcome, I've been stuck for more than one hour.

回答1:

Remove this line from your model:

attr_accessor :name, :profession

This is overriding the accessors already provided by activer record after you migrated your model and added those fields. This is causing them not to be saved to the db.
