Enforce trailing slash in Rails Routing

Question

Adding a trailing slash in your links is easy enough with {:trailing_slash => true}, but this doesn't account for if a user types in a non-slashed url. Is there a way to enforce trailing slashes via redirects in the router? ``` get "/:controller/:id" => redirect{|params| "/#{params[:controller]}/#{params[:id]}/" } ``` The above leads to a circular loop. Why? a relative link of "./subclass" on ``` /parent/1 ``` is much different than ``` /parent/1/ ```

Accepted Answer

in the config/application.rb file, add

```
config.action_controller.default_url_options = { :trailing_slash => true }
```

in the Application class
