Ghanem rating的使用

//进入haxibiao.com里

cd /data/www/haxibiao.com

//通过composer拉入包

composer require ghanem/rating

//进入app/config/app.php添加下面

' providers '  => [

 Ghanem \ Rating \ RatingServiceProvider :: class ];

//生成迁移

php artisan rating:migration

//迁移后会多出一张ratings的表

php artisan migrate

//在video模型里面

use Ghanem\Rating\Traits\Ratingable as Rating;

class Video extends Model{

    use Rating;

}

//然后就可以对video进行评分，数据需从页面传递

$user = Auth::user();

$video = Video::find($video_id);

$rating = $video -> ratingUnique(['rating' =>$score],$user);

//判断是否已经评分，先添加Rating模型

php artisan make:model Rating

//在Rating模型里面

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Rating extends Model 

{

    protected $table = 'ratings';

    protected $fillable = [

'rating',

'ratingable_type',

        'ratingable_id',

'author_type',

'author_id'

];

}

//在user模型里面对Rating一对多关联

public function ratings(){

        return $this->hasMany('App\Rating','author_id','id');

    }

//判断

if(empty($user->ratings()->where('ratingable_id',$video_id)

            ->where('ratingable_type','App\Video')

            ->first()))
