Ruby on Rails REST设计问题-在帐户之间转移资金 [英] Ruby on Rails REST design question - transfer money between accounts

问题描述

我有一个Account类，想要实现转帐屏幕，以允许用户在2个帐户之间转帐。

I have an Account class, want to implement transfer screens to allow a user to transfer money between 2 accounts.

我将如何以RESTfull方式实现这种方式？

How would I implement this ins RESTfull way?

我拥有标准的帐户和其他操作，没关系。但是我应该如何实现传输呢？

I have the standard account and rest actions for that, thats fine. But how would I implement transfer?

通常，我只需添加一个名为 transfer（称为渲染屏幕）和 transfer_update（提交时称为）的方法即可。帐户控制器和相应的视图，但是我不认为这非常RESTful。

Normally I would just add a method called "transfer" (called to render the screen) and "transfer_update"(called on submit) to the accounts controller and corresponding views, but I don think this is very RESTfull.

推荐答案

您提到的是Account类，但没有提到代表过帐或日记帐的类。参见 http://homepages.tcp.co.uk/~m-wigley/ gc_wp_ded.html （已存档）。

You mention your Account class, but not the class that represents postings or journals. See http://homepages.tcp.co.uk/~m-wigley/gc_wp_ded.html (Archived).

使用引用站点的语言，为传输创建的资源是日记（条目） ，由两个发布组成，每个发布到不同的帐户。因此，您需要一个JournalsController。要添加传输，您需要对JournalsController的index操作进行POST。参数将包括日期，金额，借方帐户，贷方帐户，收款人，备忘录等。

Using the language of the referenced site, the "resource" that's being created for a transfer is a journal (entry), consisting of two postings, each to different accounts. So you would want a JournalsController. To add a transfer you would POST to the index action of the JournalsController. Parameters would include date, amount, debit_account, credit_account, payee, memo, etc.

在AccountsController上使用REST用于创建，更新或删除帐户，而不是过帐（交易））。

Using REST on AccountsController would be for creating, updating, or deleting accounts, not postings (transactions) which are contained by accounts.
