我们之前写完了人员管理和角色管理的增删改查，现在，让我们把人员管理和角色相关联起来。

　　更改AdminCreateRequest.php

　　我们更改此文件添加时添加对于角色的验证，更改后如下：

　　<?phpnamespace App\Http\Requests;use Illuminate\Foundation\Http\FormRequest;use Illuminate\Contracts\Validation\Validator;use Illuminate\Validation\ValidationException;use Symfony\Component\HttpFoundation\Response;class AdminCreateRequest exts FormRequest{ /** * Determine if the user is authorized to make this request. * * @return bool */ public function authorize() { return true; } /** * Get the validation rules that apply to the request. * * @return array */ public function rules() { return [ // 'username'=>'bail

　　required', 'password'=>'bail

　　required

　　min:10

　　max:30', 'role'=>'bail

　　required' ]; } public function messages(){ return [ 'username.required'=>':attribute 不能为空', 'password.required'=>':attribute 不能为空', 'password.min'=>':attribute 最小为10位长度', 'password.max'=>':attribute 最大为30位长度', 'role.required'=>':attribute 不能为空' ]; } public function attributes(){ return [ 'usernmae'=>'用户名', 'password'=>'密码', 'role'=>'用户角色' ]; } protected function failedValidation(Validator $validator) { // 此处自定义表单验证错误信息 $data = [ 'code' => 1000, 'msg' => $validator->errors(), ]; $respone = new Response(json_encode($data)); throw (new ValidationException($validator, $respone)) ->errorBag($this->errorBag) ->redirectTo($this->getRedirectUrl()); }}更改admin.blade.php

　　更改admin.blade.php添加角色选择框

　　@exts('admin.common')@section('content')<button type="button" class="btn btn-primary" style="margin:10px auto;" onclick="onShowAdd()">添加</button> <table class="table table-hover table-bordered"> <thead> <tr> <th scope="col">ID</th> <th scope="col">名称</th> <th scope="col">操作</th> </tr> </thead> <tbody> @foreach ($admins as $k=>$v) <tr> <th scope="row">{{$v['id']}}</th> <td>{{$v['username']}}</td> <td> <button type="button" class="btn btn-outline-primary" onclick='editAdmin("{{route("admin.detail",array("id"=>$v["id"]))}}")'>编辑</button> <button type="button" class="btn btn-outline-danger" onclick="deleteAdmin({{$v['id']}})">删除</button> </td> </tr> @foreach </tbody> </table> <nav aria-label="Page navigation example"> <ul class="pagination justify-content-center"> @if($admins->currentPage()!=1) <li class="page-item"><a class="page-link" href="{{route('admin.index').'?page=1'}}">首页</a></li> <li class="page-item"><a class="page-link" href="{{route('admin.index').'?page='.($admins->currentPage()-1)}}">上一页</a></li> <li class="page-item"><a class="page-link" href="{{route('admin.index').'?page='.($admins->currentPage()-1)}}"> {{$admins->currentPage()-1}}</a></li> @if <li class="page-item"> <a class="page-link" href="{{route('admin.index').'?page='.($admins->currentPage())}}" style="background:black;color:white"> {{$admins->currentPage()}} </a> </li> @if($admins->currentPage()!=$admins->lastPage()) <li class="page-item"><a class="page-link" href="{{route('admin.index').'?page='.($admins->currentPage()+1)}}"> {{$admins->currentPage()+1}}</a> </li> <li class="page-item"><a class="page-link" href="{{route('admin.index').'?page='.($admins->currentPage()+1)}}">下一页</a></li> <li class="page-item"><a class="page-link" href="{{route('admin.index').'?page='.$admins->lastPage()}}">末页</a></li> @if </ul> </nav> <!-- 添加弹框 --> <p class="modal fade" id="addModel" tabindex="-1" aria-labelledby="exampleModalLabel" aria-hidden="true"> <p class="modal-dialog modal-dialog-centered"> <p class="modal-content"> <p class="modal-header"> <h5 class="modal-title" id="exampleModalLabel">添加人员</h5> <button type="button" class="close" data-dismiss="modal" aria-label="Close"> <span aria-hidden="true">×</span> </button> </p> <p class="modal-body"> <p class="form-group"> <label for="username_id">用户名</label> <input type="username" class="form-control" id="username_id" aria-describedby="emailHelp"> <small id='username_err_id'></small> </p> <p class="form-group"> <label for="passwd_id">密码</label> <input type="password" class="form-control" id="password_id"> <small id='password_err_id'></small> </p> <p class="form-group"> <label for="role_id">角色</label> <select class="custom-select" id="role_id"> @foreach ($roles as $k=>$v) <option value='{{$v["id"]}}'>{{$v['role_name']}}</option> @foreach </select> <small id='role_err_id'></small> </p> </p> <input type="hidden" id="admin_id"> <p class="modal-footer"> <button type="button" class="btn btn-secondary" data-dismiss="modal">关闭</button> <button id="submit_id" type="button" class="btn btn-primary">确定</button> </p> </p> </p> </p> <style> #password_err_id,#username_err_id,#role_err_id{ color:red;

　　添加对于角色相关表的数据添加，如下：
