Question

我希望用户能够创建/更新我的＆＃34; Person＆＃34;资源，包括互相覆盖。目前，我能够捕获创建初始＆＃34; Person＆＃34;但我无法弄清楚如何捕获和显示更新资源的用户。

例如，如果用户1 创建了一个项目，那么 user 2 会更新此项目，我想显示该项目最近由用户编辑2 。

这是我的控制人员，非常感谢任何帮助谢谢！

class PeopleController < ApplicationController
  before_action :set_person, only: [:show, :edit, :update, :destroy]
  before_action :authenticate_user!, except: [:index, :show]

  # GET /people
  # GET /people.json
  def index
    @people = Person.all
  end

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

  # GET /people/new
  def new
    @person = current_user.person.build
  end

  # GET /people/1/edit
  def edit
  end

  # POST /people
  # POST /people.json
  def create
    @person = current_user.person.build(person_params)

    respond_to do |format|
      if @person.save
        format.html { redirect_to @person, notice: 'Person was successfully created.' }
        format.json { render action: 'show', status: :created, location: @person }
      else
        format.html { render action: 'new' }
        format.json { render json: @person.errors, status: :unprocessable_entity }
      end
    end
  end

  # PATCH/PUT /people/1
  # PATCH/PUT /people/1.json
  def update
    respond_to do |format|
      if @person.update(person_params)
        format.html { redirect_to @person, notice: 'Person was successfully updated.' }
        format.json { head :no_content }
      else
        format.html { render action: 'edit' }
        format.json { render json: @person.errors, status: :unprocessable_entity }
      end
    end
  end

  # DELETE /people/1
  # DELETE /people/1.json
  def destroy
    @person.destroy
    respond_to do |format|
      format.html { redirect_to people_url }
      format.json { head :no_content }
    end
  end

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

    # Never trust parameters from the scary internet, only allow the white list through.
    def person_params
      params.require(:person).permit(:name, :twitter, :facebook, :instagram, :vine)
    end
end

Answer 1

在updated_by表格中创建posts列，每次用户更新帖子时，都会使用updated_by的值更新列current_user。

Answer 2

这样做的简单方法是维护一个名为updated_by的列，并将当前用户更新为@Andrey在前一条评论中提到的内容。
但是，如果您正在寻找更广泛的跟踪，您可以使用可审核 gem 你可以看看这个： https://github.com/harley/auditable
