Question

我想在将数据存储到数据库之前验证输入字段，因此我浏览了laravel文档并遵循这些

php artisan make:request StoreLessons

在StoreLessons

中

public function rules()
    {
        return [
            'title' => 'required|unique:lesson',
            'body' => 'required',
        ];
    }

在我的控制器中

namespace App\Http\Controllers;

use Response;
use App\lesson;
use Illuminate\Http\Request;
use App\Acme\Transformers\LessonTransformer;
use Illuminate\Support\Facades\Input;
use App\Http\Requests\StoreLessons;

class LessonsController extends ApiController 
{

    protected $lessonTransformer;

    function __construct(LessonTransformer $lessonTransformer) 
    {
        $this->lessonTransformer = $lessonTransformer;
    }

    //fetch all and pass a metadata 'data' 
    public function index() 
    {
        $lessons = Lesson::all();

        return $this->respond([
            'data' => $this->lessonTransformer->transformCollection($lessons->all())
        ]);
    }

    //add a new lesson to lessons table
    public function store(StoreLessons $request) 
    {
        Lesson::create($request->all());

        //Lesson::create(input::all());

        return $this->respondCreated('Lesson created successfully');
    }


}

现在我收到此错误

QueryException in Connection.php line 770:
SQLSTATE[42S02]: Base table or view not found: 1146 Table 'laravel_api.lesson' doesn't exist (SQL: select count(*) as aggregate from `lesson` where `title` = the)

我不知道为什么它正在寻找lesson表我有lessons表

但store()函数可以使用默认验证

//this works fine but i wan to do the validation 
    public function store() 
    {
        if (! input::get('title') or ! input::get('body')) {
            return $this->respondBadRequest();
        }

        Lesson::create(input::all());

        return $this->respondCreated('Lesson created successfully');
    }

谢谢

Answer 1

unique:table,column,except,idColumn

唯一语法如上所述，传递的第一个参数是表名。

public function rules() { 
    return [ 'title' => 'required|unique:lesson', 'body' => 'required', ];
}

此处的唯一规则会查找表lesson。尝试将其更改为lessons

Answer 2

请在相关的模型类名之后写下面的行。

类xyz扩展了Model { 受保护的$ table =＆＃39;课程＆＃39;;
