Rails在没有使用ID的情况下将带有条的路由进行匹配 [英] Rails match routes with slugs without using ID in link

问题描述

在我的路线文件中，我可以轻松地将看起来像这样的匹配项放在一起，并且工作正常

In my routes file I can easily put together a match that looks like this and works just fine

match '/:slug/:id' => "pages#show", :id => :id

此链接适用的链接是

link_to n.name, "/" + n.slug + "/" + n.id.to_s

我不想在URL中包含ID号，所以我希望这样做

I'd rather not include the ID number in the URL so I was hoping to do something like

match '/:slug' => "pages#show", :slug => :slug

但是问题在于，它没有为页面show controller提供ID。是否有某种方法可以使用：slug将其与数据库中的页面相匹配，以便找到：id，以便可以将：id传递给控制器​​？

But the problem is this doesn't provide the id to the pages show controller. Is there some way of using the :slug to match it to the page in the database with this slug to find the :id so I can pass the :id to the controller?

推荐答案

在您的路线中使用此

match "/:slug" => "pages#show"

然后在您的控制器中使用slug来找到该页面

And in your controller find the page by slug using this

@page = Page.find_by_slug(params[:slug])
