Rails 4 devise用戶可以注冊但不能登錄，

Question

我正在構建一個Rails應用程序（我正在使用Rails 4）並使用Devise進行身份驗證，問題是我可以注冊，注冊后用戶會自動登錄，但是如果我注銷，我無法登錄，這是我的模型控制器和路線代碼。

控制器：

class ApplicationController < ActionController::Base
  before_filter :configure_permitted_parameters, if: :devise_controller?
  protected

  def configure_permitted_parameters
    devise_parameter_sanitizer.for(:sign_up) { |u| u.permit(:username, :email, :password,   :password_confirmation, :remember_me) }
    devise_parameter_sanitizer.for(:sign_in) { |u| u.permit(:username, :password) }
  end
end

模型：

class User < ActiveRecord::Base
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable

  def user_params
    params.require(:user).permit(:email, :password, :password_confirmation, :remember_me, :username)
  end
end

路線：

Rails.application.routes.draw do
  devise_for :users, path_names: {sign_in: "login", sign_out: "logout"}

  resources :rezultates

  resources :notificaris do
    member do
      get :trimite
      get :trimiteneplata
      get :tz
    end
  end

  resources :programaris

  resources :pacients do
    collection { post :import }
    resources :programaris
    resources :rezultates
    member do
      get :trimite
    end
  end

  root to: 'pacients#index'
end

我嘗試登錄時來自服務器的日志

Answer 1

如果您看一下devise github repo 。 它說

To permit simple scalar values for username and email, use this

def configure_permitted_parameters
  devise_parameter_sanitizer.for(:sign_in) { |u| u.permit(:username, :email) }
end
