Question

在我的rails 5应用程序中，我使用“devise_token_auth”gem来开发基于令牌的API以进行身份验证。到目前为止，一切都运行良好，但突然间我得到了以下错误，

NoMethodError (undefined method `create_token' for #<User:0x00000002268570>

无法在谷歌上找到任何解决方案。以下是完整错误，

Did you mean?  created_at):

我通过使用文档的Excluding Modules部分解决了此错误。

# app/models/user.rb
class User < ActiveRecord::Base

  # notice this comes BEFORE the include statement below
  # also notice that :confirmable is not included in this block
  devise :database_authenticatable, :recoverable,
         :trackable, :validatable, :registerable,
         :omniauthable

  # note that this include statement comes AFTER the devise block above
  include DeviseTokenAuth::Concerns::User
end

解决了未定义方法问题的原因包括了DeviseTokenAuth :: Concerns :: User，但我需要此部分，因为它需要确认（我将include放在devise块之前）

devise_token_auth未定义方法'create_token'问题
