<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Post extends Model
{
    /**
     * Array of relationships to load.
     * @var array
     */
    protected $with = ['comments'];

    /**
     * @return \Illuminate\Database\Eloquent\Relations\HasMany
     */
    public function comments()
    {
        return $this->hasMany(Comment::class);
    }

    /**
     * @param array $relations
     * @return static
     */
    public static function onlyWith($relations = [])
    {
        $instance = new static;
        $instance->with = $relations;

        return $instance;
    }
