Rails: Route to custom controller action

Question

I have a really hard time understanding routes and I hope someone can help me. Here's my custom controller ``` class SettingsController < ApplicationController before_filter :authenticate_user! def edit @user = current_user end def update @user = User.find(current_user.id) if @user.update_attributes(params[:user]) # Sign in the user bypassing validation in case his password changed sign_in @user, :bypass => true redirect_to root_path else render "edit" end end end ``` and I have the file settings/edit.html.erb and my link ```

<%= link_to('Settings', edit_settings_path) %>

``` The route ``` get "settings/edit" ``` doesn't work for this, because then I get ``` undefined local variable or method `edit_settings_path' for #<#:0x00000002b40a80> ``` What route do I have to give this? I can't figure it out. If I put "/settings/edit" instead of a path it messes up as soon as I'm on a other resource page because the resource name is put BEFORE settings/edit Thx

Accepted Answer

Following should do:

```
get 'settings/edit' => 'settings#edit', :as => :edit_settings
# you can change put to post as you see fit
put 'settings/edit' => 'settings#update'
```

If you use `/settings/edit` directly in link, you shouldn't have problem with other resource name being prepended in path. However, without the leading slash, i.e. `settings/edit` it might have that issue.

Reason why `edit_settings_path` is not working might be because you didn't declare a named route. You have to use `:as` option to define by which method you will be generating this path/url.
