RegistrationsController中的NameError #create

标签： ruby-on-rails ruby-on-rails-3 devise

昨天刚安装了Devise，SIGN-IN功能正常工作即：如果输入错误的密码/用户名，它将有一个闪存MSG，我可以使用正确的信息登录等等...... / p>

但是，SiGN-UP区域并不完全相同。当我输入错误的登录凭据时，我收到以下错误：

RegistrationsController中的NameError #create

未定义的局部变量或＃

的方法`authentications'

不确定要包含哪些其他控制器或内容，所以一旦你问，我会用它们更新OP。

User.rb控制器 

class User < ActiveRecord::Base
  has_many :authentication

  # Include default devise modules. Others available are:
  # :token_authenticatable, :lockable, :timeoutable and :activatable
  devise :database_authenticatable, :registerable, 
         :recoverable, :rememberable, :trackable, :validatable

  # Setup accessible (or protected) attributes for your model
  attr_accessible :email, :password, :password_confirmation
  # attr_accessible :title, :body

  def apply_omniauth(omniauth)
    self.email = omniauth['user_info']['email'] if email.blank?
    authentications.build(:provider => omniauth['provider'], :uid => omniauth['uid'])

  end

  def password_required?
    (authentications.empty? || !password.blank?) && super
  end
end

身份验证控制器 

class AuthenticationsController < ApplicationController
  def create
    omniauth = request.env["omniauth.auth"]
    authentication = Authentication.find_by_provider_and_uid(omniauth['provider'], omniauth['uid'])
    if authentication
      flash[:notice] = "Signed in successfully."
      sign_in_and_redirect(:user, authentication.user)
    elsif current_user
      current_user.authentications.create!(:provider => omniauth['provider'], :uid => omniauth['uid'])
      flash[:notice] = "Authentication successful."
      redirect_to authentications_url
    else
      user = User.new
      user.apply_omniauth(omniauth)
      if user.save
        flash[:notice] = "Signed in successfully."
        sign_in_and_redirect(:user, user)
      else
        session[:omniauth] = omniauth.except('extra')
        redirect_to new_user_registration_url
      end
    end
  end
end

答案 0 :(得分：2)

我发现了它！ （我希望如此）

has_many :authentication

应该是：

has_many :authentications

为什么呢？因为Rails希望您为has_many和其他情况复数对象的名称。
