使用 Laravel 关系从多步表单中插入数据

Question

我有一个问题要问你。

我有一个多步骤表单：

1. 贷款（从计算器发送）
2. 创建一个帐户（电子邮件 + 密码）
3. 个人数据（名字、姓氏、电话号码等...）
4. 地址（街道、城市、州 + 如果有通信地址等...）
5. 就业（雇主名称、雇主地址等...）
6. 完成（发送前检查您的数据...）

表单中的输入总数为 60

我想把它拆分成更多的表格

1. 用户
2. 贷款
3. 个人的
4. 地址
5. 就业

虽然我尝试了这个，但有些东西告诉我，即使它有效，这种方法也不是很安全。

因此，我转向这里寻求建议和帮助，因为您会这样做吗？

我不知道我是否正确理解 Laravel 关系，但我尝试...

对不起，我的英语是斯洛伐克语，我帮助过 Google 翻译

如果你想用一个请求做所有事情（构建大型表单并用 JS 操作它）你的 store 方法非常好。

您必须从 store 方法中删除 Loan $loan, User $user, Personal $personal, Adress $adress, Eployment $eployment,，因为您没有为此使用模型路由绑定：https://laravel.com/docs/5.8/routing#route-model-binding。

您也不需要关联 ($user->personal()->associate($user);) 或附加所有内容，因为您已经将 user_id 添加到您创建的每个模型中。

也不要忘记表单验证。
