php - 使用 laravel5 将数据插入数据库时​​出错

Question

我是 laravel5 框架的新手。当我当时使用 laravel5 将数据插入数据库时​​，我得到类似...的错误。

ClientFormRequest.php 第 10 行中的 FatalErrorException: 无法在类 App\Http\Requests\ClientFormRequest 中使静态方法 Symfony\Component\HttpFoundation\Request::create() 非静态

我所有的文件都在下面...

app/Http/Controller/RegisterController.php

<?php namespace App\Http\Controllers;

use App\Http\Requests;
use App\Http\Controllers\Controller;
use App\Http\Requests\ClientFormRequest;

use Illuminate\Http\Request;

class RegisterController extends Controller {

    public function create()
    {
        return view('Client.client');
    }

    public function store(ClientFormRequest $request)
    {       


        return \Redirect::route('Client.client')
        ->with('message', 'Record Inserted!');
    }

}

app/Http/Requests/ClientFormRequest.php

<?php namespace App\Http\Requests;


use Stringy\create;

use App\User;
use Validator;
use App\Http\Requests\ClientFormRequest;

class ClientFormRequest extends Request {

    /**
     * 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()
    {

    }

    public function validator(array $data)
    {
        return Validator::make($data, [
                'fullname' => 'required|max:255',
                'email' => 'required|email|max:255|unique:users',
                ]);
    }

    public function create(array $data)
    {
        return client::create([
            'fullname' => $data['fullname'],
            'email' => $data['email'],
        ]);
    }
}

Answer 1

首先，我建议您观看Laravel 5 Fundamentals反复因为它是免费的。其他系列也提供了很好的信息。

其次，我建议您至少使用 Sublime Text和一些有用的包，能够检查系统文件的深度嵌套关系(命名空间、接口(interface)、继承树等...)。如果你不会/可能不会，这位 friend 随时为你服务Laravel API

第三，据我所知，Laravel Request 构建在 Symfony 的 Request Component 之上。由于您试图将其核心功能之一重载为非静态，因此您会收到此错误。

此外，老实说，我不会将我的用户/客户端模型创建逻辑放入请求中。 Laravel 为这种误解提供了一个很好的例子。在 App\Services 文件夹中，您将找到 Laravel oem 用户模型的注册服务。

让我们检查不同情况下的问题。

但首先，基本...

假设所有逻辑都应该放在 Controller 中。

RegisterController.php

<?php namespace App\Http\Controllers;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use Request;

class RegisterController extends Controller {
    public function create()
    {
        return view('Client.client');
    }

    public function store()
    {   
        $data = Request::all(); //requested data via Facade
        //prepare validatation
        $validation = Validator::make($data, [ 
                'fullname' => 'required|max:255',
                'email' => 'required|email|max:255|unique:users',
                ]);
        //validate
        if ($validation->fails())
        {
            return redirect()->back()->withErrors($v->errors());
        }
        // create the client
        Client::create([
            'fullname' => Request::input('fullname'),
            'email'    => Request::input('email'),
        ]);

        return \Redirect::route('Client.client')
        ->with('message', 'Record Inserted!');
    }

}

第二种解决方案

您可能愿意分离验证逻辑并应用一些依赖注入(inject)。

RegisterController.php

<?php namespace App\Http\Controllers;

use App\Http\Requests;
use App\Http\Controllers\Controller;
use App\Http\Requests\ClientFormRequest;

class RegisterController extends Controller {

    public function create()
    {
        return view('Client.client');
    }

    public function store(ClientFormRequest $request)
    {   
        // create the client
        Client::create([
            'fullname' => $request->input('fullname'),
            'email' => $request->input('email'),
        ]);

        return \Redirect::route('Client.client')
        ->with('message', 'Record Inserted!');
    }

}

ClientFormRequest.php

use Stringy\create;

use App\User;
use Validator;
use App\Http\Requests\ClientFormRequest;
class ClientFormRequest extends Request {

    public function authorize()
    {
        return true;
    }


    public function rules()
    {
        return [
            'fullname' => 'required|max:255',
            'email' => 'required|email|max:255|unique:users'
        ];
    }

}

第三种解决方案

您可能愿意更进一步，甚至将对象创建逻辑分离为服务以便在任何地方使用它。现在您的请求文件将保持不变。然而，

RegisterController.php

use App\Http\Requests;
use App\Http\Controllers\Controller;
use App\Http\Requests\ClientFormRequest;
use App\Services\ClientRegistrar;

class RegisterController extends Controller {

    private $registrar;

    public function __construct(ClientRegistrar $registrarService)
    {
        $this->registrar = $registrarService;
    }
    public function create()
    {
        return view('Client.client');
    }

    public function store(ClientFormRequest $request)
    {   

        $newClient = $this->registrar->create($request->all());
        return \Redirect::route('Client.client')
        ->with('message', 'Record Inserted!')->compact('newClient');
    }

}

App\Services\ClientRegistrar.php

 use App\Client;
 use Validator;
 use Illuminate\Contracts\Auth\Registrar as RegistrarContract;

 class ClientRegistrar implements RegistrarContract {

    /**
     * Get a validator for an incoming registration request.
     *
     * @param  array  $data
     * @return \Illuminate\Contracts\Validation\Validator
     */
    public function validator(array $data)
    {
        return Validator::make($data, [
           'fullname' => 'required|max:255',
        'email' => 'required|email|max:255|unique:users',
        ]);
    }

    /**
     * Create a new client instance after a valid registration.
     *
     * @param  array  $data
     * @return Client
     */
    public function create(array $data)
    {
        // create the client
        return Client::create([
                'fullname' => $data['fullname'],
                'email' => $data['email'],
            ]);
    }

 }

我的结论没有解决问题的正确和最佳方法。坚持最适合您和您的项目规模的适用方式。
