<body>
    <div id="app">
        
        @yield('content')
        
    </div>

    <script src="{ mix('js/app.js') }"></script>
    @yield('bottom-js')
    <script>
        $('#flash-overlay-modal').modal();
    </script>
</body>

上面是app.blade.php文件，这样看来@section('bottom-js')并不在#app里面。
我看视频中的文件@section('js')应该也是这样的，不在#app里面。
我在show.blade.php文件里面去掉@include('vendor.ueditor.assets')就不会报这个错误。

页面中并没有写内联样式呀！

@extends('layouts.app')

@section('content')
    @include('vendor.ueditor.assets')

好的，谢谢！！

Laravel 实战开发知乎：实现选择话题整个流程
评论发表于 6年前

public function normalizeTopic(array $topics)
{

    return collect($topics)->map(function ($topic) {
        if ( is_numeric($topic) ) {
            Topic::find($topic)->increment('questions_count');
            return (int) $topic;
        }
        $newTopic = Topic::create(['name' => $topic, 'questions_count' => 1]);
        return $newTopic->id;
    })->toArray();
}


这个是什么意思，不太明白，主要是collect($topics)->map...是什么作用不太理解，之前有在哪里讲到吗？？

邮件使用 Markdown 语法
评论发表于 6年前

$email = new  \App\Mail\LessonPublished(\App\User::first());
这个返回的不应该是一个user对象么？
然后 Mail::to(\App\User::first())->send($email);
这句我就更不理解了！麻烦jelly 给解释一下；谢谢！

使用Laravel-Admin遇到的问题
帖子发表于 6年前

下面是我在控制器中写的添加方法

public function store(Request $request)
    {
        $data = $request->all();
        $result = VenueRepositories::addVenue($data);
        if($result['status'] == 0){
            return Response::Json(['status'=>0, 'message'=>'添加场馆失败']);
        }
        return Response::Json(['status'=>1, 'message'=>'添加场馆成功']);
    }

当返回Response 时就会报错：

Dingo API 初探
评论发表于 6年前

class LessonsController extends BaseController
{
    public function index(){
        $lessons = Lesson::all();
        return $this->collection($lessons, new LessonTransformer());
    }
}

最后这个collection 是调用的那里的方法？
还有new LessonTransformer() 虽然实例化了但是什么时候调用的transform()这个函数呢？？
