Devise ERROR: Auth token has already been taken

Question

尝试在我的 RoR webapp 中注册给我 Devise Message "Auth token has already been taken" 此外，webapp 有一个 API 并且工作正常，不提供任何消息，这仅在我尝试使用 HTML 视图时发生。

user_controller.rb

before_action :set_user, only: [:show, :edit, :update, :destroy]

# DELETE /users/:id.:format
  def destroy
    # authorize! :delete, @user
    @user.destroy
    respond_to do |format|
      format.html { redirect_to root_url }
    end
  end

  private
    def set_user
      @user = User.find(params[:id])
    end

    def user_params
      accessible = [ :name, :email ]
      accessible << [ :password, :password_confirmation ] unless params[:user][:password].blank?
      params.require(:user).permit(accessible)
    end

User.rb

  validates :auth_token, uniqueness: true
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable
  before_create :generate_authentication_token!
  def generate_authentication_token!
    begin
      self.auth_token = Devise.friendly_token
    end while self.class.exists?(auth_token: auth_token)
  end

Answer 1

这可能是因为您的数据库中已有用户，但没有 auth_token，使用 Devise.friendly_token 使用令牌

更新这些用户

Answer 2

关注以下内容 1) 打开 Rails 控制台

rails console

2) 获取用户总数

user = User.all
user.count

这应该是 1

3) 获取用户并检查授权令牌

user = User.last
user.auth_token

授权令牌将是一个空字符串，这就是您的命令失败的原因，因为用户没有有效的授权令牌

4) 为用户创建一个有效的授权令牌

user.auth_token = Devise.friendly_token
user.save

它将为用户创建一个有效的授权令牌并保存它

5) 现在您可以运行您的命令，它会完美地工作

干杯！ :)
