Question

我有一定的权限，当我对某个ID给予一定的权限时，它也会反映到其他ID上。考虑有7个权限。选择并保存它们之后，如果我转到下一个项目选择选项，则我在其中选择的先前ID也会被选中，而当我取消选中它时，它也会反映给其他人。另外，如果我仅选择7个选项中的3个并保存，然后注销并登录，则select选项中仅剩下3个选项，其他选项将被删除。

// send permissions

  var headers = new HttpHeaders().set('Authorization', 'Token ' +
    localStorage.getItem('usertoken'));

  var options = {
    headers: headers
  };
  return this.httpClient.post('/api/auth/permission_list/', data,
    options)
}

角度选择的选项也更新为其他ID
