Question

我想在返回空数组时删除它。我一直在尝试许多不同的方法，请帮助我的控制器看起来是：

public function index()
{
    return JobsResource::collection(Jobs::all())->filter();
}

我的资源文件外观：

class JobsCollection extends Resource

{

public function toArray($request)
{
    $applicants_count =Job_applicants::where('job_id',$this->id)->get()->count();

    if ($applicants_count>0) {
        return [
            'id' => $this->id,
            'title' => $this->title,
            'deadline' => $this->deadline,
            'applicants_count' => $applicants_count,
            'applicants' => new EmployeesResource($this->Employeess->take(2))
        ];
    }
}

}

它总是返回一个空数组输出：

[
 [],

{ “ id”：99， “ title”：“施工管理员-林地”， “截止日期”：“ 2018-06-30”， “ applicants_count”：10， “申请人”：[ { “ name”：“求职者先生”， “枢”：{ “ job_id”：99， “ employee_id”：1 } }， { “ name”：“ Michale Feil”， “枢”：{ “ job_id”：99， “ employee_id”：2 } } ] }

控制器：

public function index() {
    $jobs = Jobs::has('Employeess')->with('Employeess')->withCount('Employeess')->get();

    return JobsResource::collection($jobs);
}

资源文件：

class JobsCollection extends Resource
{

    public function toArray($request)
    {
            return [
                'id' => $this->id,
                'title' => $this->title,
                'deadline' => $this->deadline,
                'applicants_count' => $this->Employeess_count,
                'applicants' => new EmployeesResource($this->Employeess->take(2))
            ];
    }
}

删除Resource :: Collection中的空数组不起作用Laravel
