Question

我在我的应用程序中添加了一个名为Tokened.rb的模块，并将include Tokened添加到我的模型中。但是，现在当我尝试加载该模型时，我得到一个“TestingsController #index中的NameError”错误...我没有在我的TestingsController中包含Tokened，但不确定为什么我应该或我应该把它放在哪里。

我的代码： testing.rb

class Testing < ActiveRecord::Base
  include Tokened
end

My Tokened.rb模块：

module Tokened

  extend ActiveSupport::Concern

  included do
    after_initialize do
      self.token = generate_token if self.token.blank?
    end
  end

  private
    def generate_token
      loop do
        key = SecureRandom.base64(15).tr('+/=lIO0', 'pqrsxyz')
        break key unless self.class.find_by(token: key)
      end
    end
end

最后，我的测试控制器：

  class TestingsController < ApplicationController
  before_action :set_testing, only: [:show, :edit, :update, :destroy]

  # GET /testings
  # GET /testings.json
  def index
    @testings = Testing.all
  end

  # GET /testings/1
  # GET /testings/1.json
  def show
  end

  # GET /testings/new
  def new
    @testing = Testing.new
  end

  # GET /testings/1/edit
  def edit
  end

  # POST /testings
  # POST /testings.json
  def create
    @testing = Testing.new(testing_params)
    respond_to do |format|
      if @testing.save
        format.html { redirect_to @testing, notice: 'Testing was successfully created.' }
        format.json { render :show, status: :created, location: @testing }
      else
        format.html { render :new }
        format.json { render json: @testing.errors, status: :unprocessable_entity }
      end
    end
  end

  # PATCH/PUT /testings/1
  # PATCH/PUT /testings/1.json
  def update
    respond_to do |format|
      if @testing.update(testing_params)
        format.html { redirect_to @testing, notice: 'Testing was successfully updated.' }
        format.json { render :show, status: :ok, location: @testing }
      else
        format.html { render :edit }
        format.json { render json: @testing.errors, status: :unprocessable_entity }
      end
    end
  end

  # DELETE /testings/1
  # DELETE /testings/1.json
  def destroy
    @testing.destroy
    respond_to do |format|
      format.html { redirect_to testings_url, notice: 'Testing was successfully destroyed.' }
      format.json { head :no_content }
    end
  end

  private
    # Use callbacks to share common setup or constraints between actions.
    def set_testing
      @testing = Testing.find(params[:id])
    end

    # Never trust parameters from the scary internet, only allow the white list through.
    def testing_params
      params.require(:testing).permit(:name, :address, :signature)
    end
end

是什么给出的？我不确定这里发生了什么以及为什么它需要包含在控制器中。

首先，它应该是小写的：tokened.rb。但你的文件在哪里？它应该在modules/concerns/tokened.rb。

控制器名称错误
