Laravel 用户之间关注

1.建立用户关注用户的表 followers

执行命令：

  1 php artisan make:migration create_followers_table

****_create_followers_table.php:

  1 <?php
  2 
  3 use Illuminate\Database\Migrations\Migration;
  4 use Illuminate\Database\Schema\Blueprint;
  5 use Illuminate\Support\Facades\Schema;
  6 
  7 class CreateFollowersTable extends Migration
  8 {
  9     /**
 10      * Run the migrations.
 11      *
 12      * @return void
 13      */
 14     public function up()
 15     {
 16         Schema::create('followers', function (Blueprint $table) {
 17             $table->bigIncrements('id');
 18             $table->unsignedBigInteger('user_id')->index()->comment("被关注的用户的id");
 19             $table->unsignedBigInteger('follower_id')->index()->comment("粉丝用户的id");
 20             $table->timestamps();
 21         });
 22     }
 23 
 24     /**
 25      * Reverse the migrations.
 26      *
 27      * @return void
 28      */
 29     public function down()
 30     {
 31         Schema::dropIfExists('followers');
 32     }
 33 }
 34 
 35 

_create_followers_table.php

接着执行：

  1 php artisan migrate

2.模型关联 【添加到User.php中】

  1 /** 用户的粉丝
  2  * @return \Illuminate\Database\Eloquent\Relations\BelongsToMany
  3  */
  4 public function followers()
  5 {
  6     //外键是粉丝的id
  7     return $this->belongsToMany(self::class, 'followers', 'follower_id', 'user_id')->withTimestamps();
  8 }
  9 
 10 
 11 /** 用户关注的作者
 12  * @return \Illuminate\Database\Eloquent\Relations\BelongsToMany
 13  */
 14 public function following()
 15 {
 16     //外键是作者的id
 17     return $this->belongsToMany(self::class, 'followers', 'user_id', 'follower_id')->withTimestamps();
 18 }
