我在尝试编辑员工时遇到错误。完整的错误消息是：
ActiveRecord：：RecordNotFound in EmployeesController#edit
找不到"id"=5 的公司(*这取决于我点击的公司(
提取的源(围绕第 #57 行(：
def find_company
@company = Company.find(permitted_params[:company_id])
end
end
有了这个应用程序，我有公司和员工。我可以添加、显示和删除公司内的员工，但由于此错误，我无法编辑他们。我是 Rails 的新手，不确定我哪里出错了。
routes.rb：
Rails.application.routes.draw do
get 'welcome/index'
resources :companies do
resources :employees
end
root 'welcome#index'
get 'companies/new'
end
员工控制员：
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

请有人帮忙吗？
尝试将@company传递给edit_company_employee_path。
<%= link_to "Edit", edit_company_employee_path(@company, employee), class: "btn btn-primary btn-sm" %>
