laravel - 从 belongsToMany 关系获取原始 sql 查询

Question

如何从 belongsToMany 获取原始 sql，如“SELECT * FROM table WHERE id = 1”。

public function users(){
    return $this->belongsToMany('App\User','user_projects','project_id','user_id');
}

我试过 dd()

试过这个：

$query = $this->belongsToMany('App\User','user_projects','project_id','user_id');
        dd($query->getQuery()->toRawSql(), $query->getBindings());

输出：

Users [{"id":2,"name":"My Name","email":"email@example.com","email_verified_at":null,"currant_workspace":1,"avatar":null,"created_at":"2019-08-31 04:35:20","updated_at":"2019-08-31 04:37:26","pivot":{"workspace_id":3,"user_id":2}}]

Answer 1

我认为您无法打印查询。

这些belongsToMany()功能在初始请求之后完成。您可以调试可以使用 debugBar 插件 ( https://github.com/barryvdh/laravel-debugbar )执行的查询

希望这有帮助
