Question

我想将laravel 5.2 app表单中的请求保存到我的数据库中：

当我使用单词testdy提交请求时，我得到一个例外：

KeywordController.php第49行中的FatalThrowableError：Class 找不到“App \ Keyword”

我的控制器中的第49行是我想要构建我的模型的时候：$keyword = new Keyword($request);

您可以在下面找到KeywordController的代码：

<?php

namespace App\Http\Controllers;

use App\Keyword;
use App\Http\Requests\KeywordRequest;
use Response;
use Sentinel;

class KeywordController extends JoshController
{
    public function __construct()
    {
        parent::__construct();
    }

    /**
     * Display a listing of the resource.
     *
     * @return Response
     */
    public function index()
    {
        // Grab all the Keywords
     //   $Keywords = Keyword::all();
        // Show the page
        return View('admin.keyword.index'); //, compact('Keywords'));
    }

    public function create()
    {
        // $Keywordcategory = KeywordCategory::lists('title', 'id');
        return view('admin.keyword.create'); //, compact('Keywordcategory'));
    }

    public function store(KeywordRequest $request)
    {
        //dd($request);
        $keyword = new Keyword($request); //line 49 of my controller

        $keyword->user_id = Sentinel::getUser()->id;
        $keyword->save();

        if ($keyword->id) {
            return redirect('admin/keyword')->with('success', trans('Keyword/message.success.create'));
        } else {
            return Redirect::route('admin/keyword')->withInput()->with('error', trans('Keyword/message.error.create'));
        }
    }

    public function show(Keyword $keyword)
    {
        $comments = Keyword::all();

        return view('admin.keyword.show', compact('Keyword', 'comments', 'tags'));
    }

    public function edit(Keyword $keyword)
    {
        $Keywordcategory = KeywordCategory::lists('title', 'id');

        return view('admin.keyword.edit', compact('Keyword', 'Keywordcategory'));
    }

    public function update(KeywordRequest $request, Keyword $Keyword)
    {
        if ($request->hasFile('image')) {
            $file = $request->file('image');
            $filename = $file->getClientOriginalName();
            $extension = $file->getClientOriginalExtension() ?: 'png';
            $folderName = '/uploads/Keyword/';
            $picture = str_random(10).'.'.$extension;
            $Keyword->image = $picture;
        }

        if ($request->hasFile('image')) {
            $destinationPath = public_path().$folderName;
            $request->file('image')->move($destinationPath, $picture);
        }
        $Keyword->retag($request['tags']);

        if ($Keyword->update($request->except('image', '_method', 'tags'))) {
            return redirect('admin/keyword')->with('success', trans('Keyword/message.success.update'));
        } else {
            return Redirect::route('admin/keyword')->withInput()->with('error', trans('Keyword/message.error.update'));
        }
    }

    public function getModalDelete(Keyword $Keyword)
    {
        $model = 'Keyword';
        $confirm_route = $error = null;
        try {
            $confirm_route = route('delete/Keyword', ['id' => $Keyword->id]);

            return View('admin/layouts/modal_confirmation', compact('error', 'model', 'confirm_route'));
        } catch (GroupNotFoundException $e) {
            $error = trans('Keyword/message.error.delete', compact('id'));

            return View('admin/layouts/modal_confirmation', compact('error', 'model', 'confirm_route'));
        }
    }

    public function destroy(Keyword $Keyword)
    {
        if ($Keyword->delete()) {
            return redirect('admin/keyword')->with('success', trans('Keyword/message.success.delete'));
        } else {
            return Redirect::route('admin/keyword')->withInput()->with('error', trans('Keyword/message.error.delete'));
        }
    }
}

"keyword" => "tesdy"参数在数据库中具有相同的名称。

为什么$keyword = new Keyword($request);会抛出异常的任何建议？

感谢您的回复！

更新

我的app/Keyword.php文件如下所示：

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Keywords extends Model
{
    protected $table = 'keywords';

    protected $guarded = ['id'];
}

Answer 1

只需将Keyword中的班级名称更改为Keywords。类名应该等于它的文件名。

Answer 2

模型名称应为Keyword，更改它，这将解决问题：

class Keyword extends Model

将请求保存到数据库
