ruby-on-rails - 我在更新对象后收到一条 "patient successfully updated"消息，但 Rails 中的值保持不变？

Question

抱歉，我真的不知道如何更好地表达这个问题，但这是我的问题:

当我尝试在我的 Rails 应用程序中更新或创建一个患者对象时，值没有被发送到模型，因为当我尝试创建一个新患者时，我收到验证错误，我不得不输入值(我这样做了)，当我更新现有患者对象时，即使我收到“成功更新患者”的消息，值也不会改变

知道为什么会这样吗？

它过去工作正常，但我没有更改患者 Controller 或模型中的任何内容以使其停止工作？

如果您需要我的任何代码，请告诉我您需要什么。

Controller 创建和更新代码:

class PatientsController < ApplicationController

  before_filter :require_user
  load_and_authorize_resource

  def new
    @patient = Patient.new

    respond_to do |format|
      format.html # new.html.erb
      format.xml  { render :xml => @patient }
    end
  end

  def edit
    @patient = Patient.find(params[:id])
  end

  def create
    @patient = Patient.new(params[:patient])
    respond_to do |format|
      if @patient.save
        format.html { redirect_to(@patient, :notice => 'Patient was successfully created.') }
      else
        format.html { render :action => "new" }
      end
    end
  end

  def update
    @patient = Patient.find(params[:id])
    respond_to do |format|
      if @patient.update_attributes(params[:patient])
        format.html { redirect_to(@patient, :notice => 'Patient was successfully updated.') }
      else
        format.html { render :action => "edit" }
      end
    end
  end

end

Answer 1

 # adding the photo as an attribute to patient 
 attr_accessible :photo

这是你的问题，也许你想要 attr_accesor 而不是 attr_accesible ？
