Rails - Oct 2007 - radio_button_tag

Hello

I have a view which have 2 radio buttons :

...
<td style="width:5%">Actuel</td>
<td style="width:10%"><%= radio_button_tag(:actuel, value =
"1", checked
= false, options = {}) %>
<td style="width:5%">Last</td>
<td style="width:10%"><%= radio_button_tag(:last, value =
"1", checked false, options = {}) %></td>
...

I dont know how to proceed to control the status of my radio buttons.
When I click on the first one, i want to put the 2nd unchecked. When I
click on the 2nd one I want to uncheck the first one.

I know how to to it using html radio buttons + javascript. But using
radio_button_tag I dont know how to proceed.
Anyone can help me please?

thanks
regards

Hi

Radio buttons need to belong to the same group to be able to work together. In
your code you have two different groups, or attributes, :actuel and :last. These
need to be the same - the general form of the radio_button_tag helper is:
radio_button_tag(:attribute, tag_value, options). You can then determine which
one was pressed when the form is submitted by the value of the button given in
the params hash

Hello

Thanks for your answer.

I had put the radio buttons with the same name to be on the same group.

<td style="width:5%">actuel</td>
<td style="width:10%"><%= radio_button_tag(:type_recherche,
value = "1",
checked = false, options = {}) %>
<td style="width:5%">last</td>
<td style="width:10%"><%= radio_button_tag(:type_recherche,
value = "2",
checked = false, options = {}) %></td>


To pass the values I use a link_to_remote:

<%= link_to_remote "Rechercher",
   :update => "resultlist",
   :url => { :action => ''rechercher''},
   :with => "...+ ''&'' +
       ''type_recherche='' +
$F(''type_recherche'')",
   :complete => visual_effect(:appear, ''resultlist'',
:duration => 1.00)
%>

In my controller when i try to access to the "type_recherche" value
(my
2 radio buttons), I do this:

if params[:type_recherche].nil?
  puts "1"
  @demand.type_recherche = "0"
else
  if params[:type_recherche].to_s == ''null''
    @demand.type_recherche = "0"
  else
    puts "6 -> " + params[:type_recherche].to_s
    @demand.type_recherche = params[:type_recherche]
  end
end

When i check the first radio it works fine. I receive the value "1".
But
when i check the second radio button, i always receive null. It seems 
that the only radio button used is the first one.

Any idea about this problem.

Thanks
