Ruby on rails 如何将学校id添加到路径？

在我的search.html.haml中，我希望用户能够单击教师姓名，这将引导他们进入教师展示页面。但是，它也要求我有学校id，因为一个老师属于一个学校，一个学校有很多老师。现在，我想知道是否有一种方法可以让我在不破坏申请的情况下将学校id发送到路径。rails现在向我抛出的错误是：

没有路由匹配{:action=>“show”，：controller=>“teachers”，：id=>“1”， ：school\u id=>nil}缺少必需的密钥：[：school\u id]

这是我的档案：

search.html.haml：

.text-center
  / No search results announcement/notification
  - if @teachers.blank?
    %h2 Xin lỗi, hệ thống chúng tôi không có thông tin về giảng viên mà bạn muốn tìm.
  - else
    - @teachers.each do |teacher|
      %h2= link_to teacher.fullName, school_teacher_path(@school, teacher)
      #note
        %em
          Khoa #{teacher.department}, trường #{teacher.school.name}

class TeachersController < ApplicationController
  before_action :find_school, except: [:welcome, :search]
  before_action :find_teacher, only: [:show, :edit, :update, :destroy]

  def welcome
  end

  def show
  end

  def search
    if params[:search].present?
      @teachers = Teacher.search(params[:search], fields: [:fullName])
    else
      @teachers = nil
    end
  end

  def new
    @teacher = @school.teachers.build
  end

  def create
    @teacher = @school.teachers.create(teacher_params)
    @teacher.save
      redirect_to(@school)
  end

  def edit
  end

  def update
    @teacher.update(teacher_params)
    redirect_to(@school)
  end

  private

  def find_school
    @school = School.find(params[:school_id])
  end

  def find_teacher
    @teacher = Teacher.find(params[:id])
  end

  def teacher_params
    params.require(:teacher).permit(:firstName, :lastName, :middleName, :department, :school_id, :fullName)
  end
end

class Teacher < ActiveRecord::Base
  belongs_to :school
  has_many :ratings

  searchkick

  def name
    "#{lastName} #{middleName} #{firstName}"
  end

  def to_s
    name
  end
end

class School < ActiveRecord::Base
  has_many :teachers, dependent: :destroy

  # searchkick
end

Rails.application.routes.draw do
  devise_for :users

  resources :schools do
    # collection do
    #   get 'search'
    # end
    resources :teachers do
      collection do
        get 'search'
      end
    end
  end

  resources :teachers do
    collection do
      get 'search'
    end
    resources :ratings

  root 'teachers#welcome'

教师\u控制器.rb：

school\u teacher\u path

是用一个为零的

@school

调用的，因为

查找学校

不用于

搜索

。您可能希望将

@school

替换为

teacher.school

：

school\u teacher\u路径（teacher.school，teacher）

您也可以访问案例中的归属关系

teacher.school.id

将返回

学校的
id
