I am having trouble with my routing in a Rails application.

My routing file has:

```
resources :translations

```

Which should create several routes, including update.

Doing a rake routes shows the update route is there:

```
PUT    /translations/:id(.:format)      {:action=>"update", :controller=>"translations"}

```

However, when I use the following code to link to the update:

```
<% form_tag( {:controller => "translations", :action => "update"}, {:multipart => true}) do %>
  <p><%= label_tag "upload", translate("UI_TEXT_FORM_SELECT_AUDIO_FILE") %>:
  <%= file_field_tag "upload" %></p>
  <%= submit_tag translate("UI_TEXT_FORM_SAVE") %>
<% end %>

```

I get this result:

```
Routing Error
No route matches "/translations/10"

```

Any help would be appreciated.
