如何在 Laravel 上不使用 get() 启动模型

Question

我的模型上有这个Scholar

<?php namespace App;

use Illuminate\Database\Eloquent\Model;

class Scholar extends Model {

    protected $primaryKey = 'scholar_id';
    protected $fillable = ['ngo_id','scholar_lname','scholar_fname','scholar_image','scholar_nickname','scholar_cityAddress','scholar_permaAddress','scholar_birthday','scholar_placebirth','scholar_age','scholar_gender','scholar_email','scholar_contact'];

}

那么这是我的控制器上

$scholars = new Scholar; <------

if(Input::get('age_from'))
    $scholars->where('age', '=', Input::get('age_from'));

$scholars->get();

return $scholars;

我想启动这个，但是当我尝试时$scholars = Scholar::all();我无法->get()再使用；

无论如何如何做这个可选的where？

Answer 1

您可以使用newQuery；

$scholars = (new Scholar)->newQuery();

if(Input::get('age_from')) {
    $scholars->where('age', '=', Input::get('age_from'));
}

return $scholars->get();
