Rails STI 路由 [英] Rails STI routing

问题描述

我有一个使用 STI 的文章模型.子类是情感、类别、网关等...

I've got an article model which uses STI. The sub classes are emotions, categories, gateways etc...

在我的路线中，我有

resources :emotions, :controller => 'articles'
resources :categories, :controller => 'articles'
resources :gateways, :controller => 'articles'

这使得所有不同的子类都可以在/articles/108 或emotions/108 或categories/108 中使用 - 无论您将哪个子类放在最前面，它们都适用于所有文章.

This makes all the different sub classes available at /articles/108 or emotions/108 or categories/108 - it doesn't matter which subclass you stick at the front they all work for all articles.

我希望我所有的 url 助手都能生成文章/id 的链接 - 目前它们仍然转到特定的子类.

I would like all my url helpers to produce links to articles/id - at the moment they still go to the particular sub class.

我该怎么做?

推荐答案

如果 article 是另一个派生类的基类，比如 gateway (class Gateway )，那么也许只使用 urls由 resources :articles 生成.应该可以使用文章助手 article_path(gateway)，因为子类是从基类派生的.

If article is the base class of another derived class like gateway (class Gateway < Article), then maybe just use the urls generated by resources :articles. It should be possible to use the articles helper article_path(gateway) since the subclasses are derived from the base class.
