Rails Ruby on Rails

I SOLVED THIS PROBLEM WITH :URL => RESOURCE_PATH(@RESOURCE), BUT I DON'T KNOW HOW TO CLOSE THE TICKET. PLEASE CLOSE THIS, IF YOU COME ACROSS IT.

Wondering if anyone can help, or is having the same problem. I have a form_for helper nested inside an index view, because index viewers need to be able to update a parameter without going to a separate page (like the edit route). But this form is sending a put request to the non-specific route (/resources) instead of the specific route indicated in the generated html (/resources/:id). Put requests should be directed to the specific route to call the update action, so I'm getting an error and the database does not update.

(controller is default scaffolded version)

(index.html.erb)

<td><% form_for :resource do |f|%>
<%= f.text_field :parameter %>
<%= f.submit 'Update' %>
<% end %></td>

(routes.rb) map.resources :resources

(generated html)

<input id="resource_parameter" name="resource[parameter]" size="30" type="text" value="wtf" />
<input id="resource_submit" name="commit" type="submit" value="Update" /> 
</form></td>
