具有多个，可选和漂亮参数的路由 [英] Routes with multiple, optional, and pretty parameters

问题描述

我遇到了需要构造漂亮的url路径的情况。

I have a situation where I'm in need to constructing pretty url paths.

我有一个FilesController，需要处理以下URL：

I have a FilesController that need to handle URLs like:

mydomain.com/files/path/dir1/dir2/user/bob
mydomain.com/files/path/dir1/user/bob
mydomain.com/files/path/dir1
mydomain.com/files/user/bob

在控制器中，我希望 params [：path] 包含 / path 与 /用户和 params [：user] 包含 / user （假设只有一个用户，它是可选的。）

In the controller, I want params[:path] to contain everything between /path and /user and params[:user] to contain anything after /user (assuming only one user and it's optional).

我正在寻找最好的方法，最好在<$ c中只声明一条$ c> routes.rb 文件。我认为最棘手的部分是，在 / path 之后，可以提供文件的实际路径，深度为N倍。

I'm looking for the best way to do this, preferable with just one statement in the routes.rb file. The trickiest part, I think, is that after /path an actual path to a file might be provided, N times deep.

推荐答案

您要路由通行：

match 'files/*path/user/:user' => 'user#files'

在没有文件的情况下，您可能还需要添加一条附加路由路径：

You might also need to add an additional route for the case where there is no path:

match 'files/user/:user' => 'user#files'
