使用rateYo和willvincent/laravel rateable

我正在尝试获取评级的属性,但是我得到了

PHP注意:未定义的索引:rating in /Applications/MAMP/htdocs/eliating/app/Book.php第33行

即时消息使用 laravel ratable

理想情况下,我想获取用户评级。

所以我可以像这样用刀锋来召唤它

{{ $book->getRatingAttribute}}

所以它可以输出例如

4.5

Book.php文件

<?php
use willvincent\Rateable\Rateable;
use App\User;
use App\Rate;

public function getRatingAttribute()
{
    return Rate::where('rating', $this->attributes['rating']);
}

率.php

<?php

namespace App;


use App\User;

use Illuminate\Database\Eloquent\Model;
use willvincent\Rateable\Rateable;

class Rate extends Model
{
    protected $fillable = [
        'user_id',
        'rating'
    ];


    public $timestamps = false;

    protected $table = 'ratings';


}

架构

class CreateRatingsTable extends Migration
{
    /**
     * Run the migrations.
     */
    public function up()
    {
        Schema::create('ratings', function (Blueprint $table) {
            $table->increments('id');
            $table->timestamps();
            $table->integer('rating');
            $table->morphs('rateable');
            $table->unsignedInteger('user_id')->index();
            $table->index('rateable_id');
            $table->index('rateable_type');
            $table->foreign('user_id')->references('id')->on('users');
        });
    }

    /**
     * Reverse the migrations.
     */
    public function down()
    {
        Schema::drop('ratings');
    }
}
