Ruby on rails 轨道-嵌套的路线和表格

我在routes.rb中有

resources :reckoners do
  resources: shift_requirements
end

在我对新轮班要求的部分说明中，我有-

<%= form_for ([@reckoner, ShiftRequirment.new]) do |f| %>

等等

我如何修改表单

expndtw-1.rb

有许多：班次要求

和班次要求.rb属于：计算者

班次要求控制器.rb-

class ShiftRequirementsController < ApplicationController
  before_action :set_shift_requirement, only: [:show, :edit, :update, :destroy]

  # GET /shift_requirements
  # GET /shift_requirements.json
  def index
    @shift_requirements = ShiftRequirement.where(reckoner_id: params[:reckoner_id])
    @shift_requirement = ShiftRequirement.new
  end

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

  # GET /shift_requirements/new
  def new
    @shift_requirement = ShiftRequirement.new
  end

  # GET /shift_requirements/1/edit
  def edit
  end

  def create
    @shift_requirement = ShiftRequirement.new(shift_requirement_params)
    zero_ise @shift_requirement
    totalise_FTEs @shift_requirement

    respond_to do |format|
      if @shift_requirement.save
        format.html { redirect_to shift_requirements_path(reckoner_id:@shift_requirement.reckoner_id), notice: 'Shift requirement was successfully created.' }

类移位请求控制器

首先，您需要设置有新轮班要求的计算器。以下是如何在控制器中执行此操作（编辑了“新建”和“创建”操作。编辑了“索引”操作以跟上最佳实践：）。还添加了一个before action和set_计算器私有方法）

类移位请求控制器class ShiftRequirementsController < ApplicationController
  before_action :set_shift_requirement, only: [:show, :edit, :update, :destroy]

  # GET /shift_requirements
  # GET /shift_requirements.json
  def index
    @shift_requirements = ShiftRequirement.where(reckoner_id: params[:reckoner_id])
    @shift_requirement = ShiftRequirement.new
  end

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

  # GET /shift_requirements/new
  def new
    @shift_requirement = ShiftRequirement.new
  end

  # GET /shift_requirements/1/edit
  def edit
  end

  def create
    @shift_requirement = ShiftRequirement.new(shift_requirement_params)
    zero_ise @shift_requirement
    totalise_FTEs @shift_requirement

    respond_to do |format|
