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：

<?php

namespace App\Http\Requests;

use Illuminate\Foundation\Http\FormRequest;
use Illuminate\Contracts\Validation\Validator;
use Illuminate\Validation\ValidationException;
use Symfony\Component\HttpFoundation\Response;

class AdminCreateRequest extends 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

                @endforeach

    }
