使用 Laravel 5.2 进行软删除级联 - Soft Delete Cascading with Laravel 5.2

我正在尝试在 Laravel 中实现软删除。

这是我的人际关系

Tournament ( hasMany ) CategoryTournament (hasOne) CategorySettings
Tournament ( hasMany ) CategoryTournament (belongsToMany) CategoryTournamentUser

所以，我用这个对我有很大帮助的答案

现在，当我软删除锦标赛时，所有与类别锦标赛相关的锦标赛也会被删除。

但是后来，我尝试递归地应用它，所以我在 CategoryTournament 模型中编写了相同的代码：

static::deleting(function($categoryTournament) {
        $categoryTournament->settings()->delete();
        $categoryTournament->users()->delete();
    });

但是此代码永远不会运行。我检查了我是否有要删除的设置和用户，但没有一个是软删除的......

我错过了什么吗???它应该有效！

编辑：

现在，我正在尝试软删除用户，这只是另一个级别：

User (HasMany) Tournament ( hasMany ) CategoryTournament (hasOne) CategorySettings

所以现在，当我软删除用户时，它会删除他的锦标赛，

但它不再删除他的类别锦标赛，所以这不是配置错误。

在static boot方法中，您必须遍历toMany关系。

F.a：

namespace App;
use Illuminate'Database'Eloquent'Model;
use Illuminate'Database'Eloquent'SoftDeletes;
class Tournament extends Model
{
  use SoftDeletes;
  public function categoryTournament() {
    return $this->hasMany(CategoryTournament::class);
  }
  protected static function boot() {
    parent::boot();
    static::deleting(function($tournament) {
      foreach ($tournament->categoryTournament()->get() as $ct) {
        $ct->delete();
      }
    });
  }
}

其他文件应如下所示：

CategoryTournament.php

namespace App;
use Illuminate'Database'Eloquent'Model;
use Illuminate'Database'Eloquent'SoftDeletes;
class CategoryTournament extends Model
{
  use SoftDeletes;
  public function tournament() {
    return $this->belongsTo(Tournament::class);
  }
  public function settings() {
    return $this->belongsTo(Settings::class);
  }
  protected static function boot() {
    parent::boot();
    static::deleting(function($categoryTournament) {
      var_dump('categoryTournament');
      $categoryTournament->settings()->delete();
    });
  }
}

Settings.php

namespace App;
use Illuminate'Database'Eloquent'Model;
use Illuminate'Database'Eloquent'SoftDeletes;
class Settings extends Model
{
    use SoftDeletes;
    public function categoryTournament() {
      return $this->hasOne(CategoryTournament::class);
    }
    protected static function boot() {
    parent::boot();
    static::deleting(function($settings) {
      var_dump('settings');
    });
  }
}

Migration

use Illuminate'Database'Schema'Blueprint;
use Illuminate'Database'Migrations'Migration;
class CreateTables extends Migration
{
  /**
   * Run the migrations.
   *
   * @return void
   */
  public function up() {
    Schema::create('tournaments', function (Blueprint $table) {
      $table->increments('id');
      $table->timestamps();
      $table->softDeletes();
    });
    Schema::create('settings', function (Blueprint $table) {
      $table->increments('id');
      $table->timestamps();
      $table->softDeletes();
    });
    Schema::create('category_tournaments', function (Blueprint $table) {
      $table->increments('id');
      $table->integer('tournament_id')->unsigned();
      $table->integer('settings_id')->unsigned();
      $table->timestamps();
      $table->softDeletes();
      $table->foreign('tournament_id')->references('id')->on('tournaments');
      $table->foreign('settings_id')->references('id')->on('settings');
    });
  }
  /**
   * Reverse the migrations.
   *
   * @return void
   */
  public function down() {
    Schema::drop('category_tournaments');
    Schema::drop('settings');
    Schema::drop('tournaments');
  }
}
