Rails - Dec 2005 - Radiobutton onclick

Hi,

I would like to make a simple html which displays the contents of a
table from a database. So I put radiobuttons near the titles of the
columns to note and do a sorting by that column. But I don''t know how
to implement that the clicking on one of the radiobuttons make the
sorting. The problem is the view part. How to give a radiobutton to
make some action on a click by the helper?

The code is:

-----
<table border="1">
        <tr>
                <% for col in Product.content_columns %>
                <td width="100"><%= radio_button :index,
''head'', col.name %><%= col.name %></td>
                <% end%>
        </tr>
        <% for prod in @product %>
                <tr>
                        <% for col in Product.content_columns %>
                                <td>
                                        <%= prod.send(col.name) unless
(prod.send(col.name).to_s == "") %>
                                        <%= "&nbsp;" if
(prod.send(col.name).to_s == "") %>
                                </td>
                        <% end %>
                </tr>
        <% end %>
        <tr>
</table>

Thanks.

Another approach you can use that avoids radio buttons would be to make 
the title of each column a hyperlink with a ''sort'' param.

<%= link_to ''Column1'',
:action=>''list'', :sort=>''column1''
%>

Then have the ''list'' action pick up the
''sort'' param and use that in
your find or paginate ( :order => :sort, I think).

This basically forces the database to return the results in the sorted 
order and then re-displays it.

There are a bunch of AJAXy ways to do the same thing that look nicer, 
but this is an easy solution.

disclaimer... this was all out of my head, so some of the coding may 
need to be tweaked.

Kevin, I was lurking on the your answer.  It will make my app more
usefull.  Thanks.

FYI --    :order => :sort is actually :order => params[:sort]

Thanks again,
Greg
