ruby-on-rails - Devise サインアップ - フィールドに「空白にすることはできません」と表示されます

Question

おはよう、

サインアップに問題があります。私は手動でテストしてきましたが、サインアップはフィールドを通過していません。私は強力なパラメーターを設定しましたが、それらを使用せずに古い attr_accessible を使用してみましたが、違いはありません。

他の誰かが以前にこの問題を抱えていましたか?

application_controller.rb

class ApplicationController < ActionController::Base
before_filter :configure_permitted_parameters, if: :devise_controller?
  # For APIs, you may want to use :null_session instead.
  protect_from_forgery with: :exception


  protected

  def configure_permitted_parameters
   devise_parameter_sanitizer.for(:sign_up) { |u| u.permit(:first_name, :last_name, :profile_name, :email, :password, :password_confirmation,
        :confirmation_token, :confirmed_at, :confirmation_sent_at) }
 end
end

user.rb

class User < ActiveRecord::Base
  before_create :create_rank
  devise :omniauthable, :omniauth_providers => [:facebook]

  attr_accessible :provider, :uid

  validates :first_name, :last_name, :profile_name, presence: true
 # validates :email, presence: true,
             #  :format => { :with => /^([\w\.%\+\-]+)@([\w\-]+\.)+([\w]{2,})$/i, :on => :create },
              # :uniqueness => true,
               #:multiline => true
  validates :password, :presence => true,
                       :confirmation => true,
                       :length => {:within => 6..40},
                       :on => :create
  validates :password, :confirmation => true,
                       :length => {:within => 6..40},
                       :allow_blank => true,
                       :on => :update

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

なぜこの問題が発生しているのかよくわかりません。フォームの問題ではないと思いますが、以下のフォームを参照してください。
