ruby-on-rails - 员工控制器中的 ActiveRecord::RecordNotFound#edit

问题描述

尝试编辑员工时出现错误。完整的错误信息是：

员工控制器中的 ActiveRecord::RecordNotFound#edit

找不到“id”=5 的公司（*这取决于我点击的公司）

提取的源代码（在 #57 行附近）：

def find_company
    @company = Company.find(permitted_params[:company_id])
  end
end

有了这个应用程序，我就有了公司和员工。我可以在公司内添加、显示和删除员工，但由于此错误，我无法对其进行编辑。我是 Rails 新手，不确定我哪里出错了。

路线.rb：

Rails.application.routes.draw do
  get 'welcome/index'

  resources :companies do
    resources :employees
  end

  root 'welcome#index'

  get 'companies/new'
end

员工控制器：

class EmployeesController < ApplicationController
  before_action :find_company
  before_action :set_employee, only: %i[show edit update destroy]

  def index
    @employees = @company.employees
  end

  def show
    @employee = Employee.find(params[:id])
  end

  def new
    @employee = @company.employees.build
  end

  def edit
    @employee = Employee.find(params[:id])
  end

  def create
    @employee = @company.employees.build(permitted_params[:employee])
    if @employee.save
      redirect_to company_employees_path(@company)
    else
      render 'new'
    end
  end

  def update
    if @employee.update(forename: permitted_params[:forename],
                        surname: permitted_params[:surname])
      redirect_to company_employees_path(@company)
    else
      render 'edit'
    end
  end

  def destroy
    @employee.destroy
    redirect_to company_employees_path(@company)
  end

  private

  def set_employee
    @employee = Employee.find(permitted_params[:id])
  end

  def permitted_params
    params.permit!
  end

  def find_company
    @company = Company.find(permitted_params[:company_id])
  end
end

公司控制人：

class CompaniesController < ApplicationController

  def index
    @company = Company.all
  end

  def show
    @company = Company.find(permitted_params[:id])
    # @company = Company.first
  end

  def new
    @company = Company.new
  end

  def create
    @company = Company.new(permitted_params[:company])

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

  def destroy
    @company = Company.find(permitted_params[:id])
    @company.destroy

    redirect_to companies_path
  end

  private

  def permitted_params
    params.permit!
  end
end
