在RoR中编写嵌套表单 [英] Writing Nested Form in RoR

问题描述

我试图在ROR中编写嵌套表单。
我有两个表 Employee 和 EmployeeInfo ，并且这两个表都有一个名为 employeeID
这些表与这个键连接。
我想要做的是创建一个带有一些输入字段的表单，这些字段应该将值更新到两个表中。例如，我希望一个表单可以创建或更新名为 employee_name ， age ，地址的字段以及 city 但是 employee_name 和 age 出现在表员工和城市和地址出现在表格 EmployeeInfo 。
所以我应该怎么写表单标签来做到这一点。
如果问题是一个错误，请对不起。我真的很新鲜。请帮助

 ＃employee.rb 
班员工< / p> ActiveRecord :: Base 
 has_one：employe_info 
 accep_nested_attributes_for：employee_info 
 end 
 $ b＃employee_info.rb 
 EmployeeInfo类< ActiveRecord :: Base 
 belongs_to：employee 
 end 
  

控制器

 类EmployeesController< ApplicationController 
 
 def new 
 @employee = Employee.new 
 @ employee.build_employee_info 
 end 
 
 def create 
 @employee = Employee.new（employee_params）
 
 if @ employee.save 
 redirect_to @employee 
 else 
 render'new'
 end 
 end 
 
私人
 
 def employee_params 
 params.require（：employee）.permit（：employee_name，：age，employee_info_attributes：[：id，：city，：address ]）

Models setup

#employee.rb
Class Employee < ActiveRecord::Base
  has_one :employe_info
  accepts_nested_attributes_for :employee_info
end

#employee_info.rb
Class EmployeeInfo < ActiveRecord::Base
  belongs_to :employee
end

Controller

Class EmployeesController < ApplicationController

   def new
      @employee = Employee.new
      @employee.build_employee_info
   end

   def create
     @employee = Employee.new(employee_params)

     if @employee.save
     redirect_to @employee
     else
     render 'new'
     end
   end

   private

   def employee_params
     params.require(:employee).permit(:employee_name, :age, employee_info_attributes: [:id, :city,:address])
   end
 end
