Rails - Nov 2009 - STI, Namespaces, REST and link_to

hello,

i''ve got the STI-hierarchy Dictionary, InternalDictionary <
Dictionary
and OnlineDictionary < Dictionary.
Every submodel has its own controller. E.g. InternalDictionary is
handled by
Voc::InternalDictionaryController. As you see everything works inside
the namespace Voc (except the models).

In an index.html.erb of a controller i walk through all types of
dictionaries:

<% for dictionary in @dictionaries %>
  <tr>
    <td><%= link_to ''Edit'', [:voc,dictionary],
:method => :get %></td>
  </tr>
<% end %>

This leads to the path "voc_internal_dictionary" for objecs of type
InternalDictionary and to "voc_online_dictionary" for objects of type
OnlineDictionary. So far so good.

But I want to call the method "edit" or a methodname completely
different from the CRUD-names.I''d need something like
<td><%= link_to ''Edit'', [:voc,dictionary], :action
=> "edit" %></td>

I tried:
<td><%= link_to ''Edit'',edit_voc_dictionary_path
%></td>
but that doens''t behave polymorphic and calls the edit method of the
dictionary-controller directly.

Any ideas?

Thanks a lot
Lutz

back again, I have found an answer meanwhile:

link_to ''Edit'', polymorphic_url([:voc,dictionary],:action
=> :edit)

does exactly what I need.
