I''m having some trouble with this select tag.
I have a simple search form that passes parameters with GET. I have the
search by name working fine but want to add a drop down list to search
by classification as well.
here is what i have:
<% form_tag items_path, :method => ''get'' do %>
<table>
<tr><%= link_to ''New Item'', new_item_path
%><td></tr>
<tr><td><%= text_field_tag :search, params[:search]
%></td>
<td><%= select("class","id", @classifications.map
{|u| [u.name,u.id]})
%>
<td><%= submit_tag "Search", :name => nil
%></td></tr>
</table>
<% end %>
it works but the url looks like:
http://domain.com/items?search=&class%5Bid%5D=1
because it is sending class[id]=1
i would like it to send just class=1 (or whatever the classification id
is)
also, is there a good way to add a :prompt (although i don''t think this
is possible with just a select tag) so if a user does not select a
classification then it will not pass a GET parameter.
thanks!

Guess you could do it like this:
<%= select("class","id", @classifications.map {|u|
[u.name,u.id]},
{:prompt => ''Select an option''}) %>

answer to your first question is:
if !(params[:class] && params[:class][:id].blank?)
@items = Item.search(params[:search], params[:class][:id],
params[:page])
else
@items = Item.search(params[:search], "", params[:page])
end
for your question, I assume you want something like
http://domain.com/items?search=&class=1
to achieve that you could use the select_tag like so:
select_tag(:class, options_for_select(@classifications.map {|u|
[u.name,u.id]}))
hope that helps

<%= select_tag(:classification_id, ''<option
value="">->Base/Class</option>'' +
options_for_select(@classifications.collect{|classification|
[classification.name, classification.id]},
params[:classification_id].to_i)) %>
thanks nas!
