我已经阅读了文档,其中说如果我想使用,scss我必须运行以下命令:

ng set defaults.styleExt scss

但是,当我这样做并生成该文件时,我仍然在我的控制台中收到此错误:

ng set defaults.styleExt scss

我该如何解决？

我在Laravel webapp中得到了这个:

@foreach($mentors as $mentor)
    @foreach($mentor->intern as $intern)
        <tr class="table-row-link" data-href="/werknemer/{!! $intern->employee->EmployeeId !!}">
            <td>{{ $intern->employee->FirstName }}</td>
            <td>{{  $intern->employee->LastName }}</td>
        </tr>
    @endforeach
@endforeach

我怎么能检查是否有$mentors->intern->employee？

当我做 :

@if(count($mentors))

它没有检查.

有没有办法在不重新制作迁移顺序的情况下更改迁移顺序？因为现在我的外键有问题-_-(使用laravel)

如何上传多个文件Laravel 5.3？如果我尝试使用1张图片,它可以正常工作,但不会上传多张图片.

这是我的代码:

 if($request->hasFile('attachment'))
 {
    foreach ($request->allFiles('attachments') as $file) {
        $file->store('users/' . $user->id . '/messages');
    }
 }

是否可以使用https://github.com/tymondesigns/jwt-auth 获取current user？因为现在我只能生成一个令牌(当用户登录时).

public function login(Request $request)
{
    $credentials = $request->only('email', 'password');

    try {
        if (! $token = JWTAuth::attempt($credentials)) {
            return response()->json(['error' => 'invalid_credentials'], 401);
        }
    } catch (Tymon\JWTAuth\Exceptions\JWTException $e) {
        return response()->json(['error' => 'could_not_create_token'], 500);
    }

    return response()->json(compact('token'));
}

我在contains集合https://laravel.com/docs/5.3/collections#method-contains上使用Laravel 方法.但它对我不起作用.

foreach ($this->options as $option) {
    if($options->contains($option->id)) {
        dd('test');
    }
}

dd($options); 看起来像这样:

Collection {#390
  #items: array:1 [
    0 => array:3 [
      0 => array:7 [
        "id" => 10
        "slug" => "test"
        "name" => "test"
        "poll_id" => 4
        "created_at" => "2016-11-12 20:42:42"
        "updated_at" => "2016-11-12 20:42:42"
        "votes" => []
      ]
      1 => array:7 [
        "id" => 11
        "slug" => "test-1"
        "name" => "test"
        "poll_id" => 4
        "created_at" => "2016-11-12 20:42:42"
        "updated_at" => "2016-11-12 20:42:42"
        "votes" …

我正在使用laravel并且我已经编写了一些测试文件.但是我怎么能只执行一个文件呢？当我这样做时:phpunit tests/resulttesting/school/deleteSchoolForRealTest它抛出一个错误:

无法打开文件"tests/resulttesting/school/deleteSchoolForRealTest.php".

当我运行phpunit时,它会运行我的所有测试.我怎么能只执行一个文件夹？我在Mac上.

我正在尝试安装,Laravel valet但我一直在(当我访问domain.dev时):

It works! 

我已经尝试了很多.例如:

remove valet 
stop apache (apachectl stop)
composer global require laravel/valet
valet install
valet restart

但那对我不起作用.我也安装Laravel Homestead 在一个流浪盒中.也许这与它有关？我可以访问我的Homestead网站.

我该如何解决这个问题？

我正在尝试添加polyfill到我的vue.js 2.0/Laravel5.3应用程序,因为在Internet Explorer 11中我收到一个错误:

vuex requires a Promise polyfill in this browser.

所以我跟着我使用ecm 6 的文档,所以我做了:

npm install --save-dev babel-polyfill

并在我的bootstrap.js顶部添加了这个:

import "babel-polyfill";

但在Internet Explorer中仍然存在相同的错误.我该怎么做或我在这里做错了什么？

我想在我的vue.js应用程序中接收json,如下所示:

  new Vue({
            el: 'body',
            data:{
                role: '',
                company: '',
                list:[],
                created: function() {
                  this.getJson();
                },
                methods: {
                    getJson: function(){
                        $.getJSON('http://domain.dev/data',function(task){
                          this.list = task;
                        }.bind(this));
                    }
                }
            }
        });

但结果是空的？当我在邮递员中测试这个时,url返回json.我在这做错了什么？
