Rails
1

hi,
i would like to change a partial in my view with the change of the
item in a select_tag:

in the view:

<%= observe_field(“payment_id”, :url => {:controller
=>‘user_admins’ ,:action => ‘rend_part’},:on => ‘change’, :frequency
=> 0.1) %>
<%= select( “payment”, “id”, { “Visa” => “1”, “Mastercard” => “2”}) %>

in controller :

def rend_part

if params[:payment][‘id’] == ‘1’
render :partial => “patial_one”
else
render :partial => “patial_two”

end
end

And what happens when you do this? Does it work? Have you got a
function in place to update the page?

In long-hand Prototype.js code, this would look something like this:

$(‘my_picker’).observe(‘change’,function(evt){
new Ajax.Request(‘rend_part’,{
parameters:{
payment_id:$F(‘my_picker’)},
onSuccess:function(transport){
$(‘some_div’).replace(transport.responseText);
}
}
});
});

How you go about doing this with the Ajax helpers is an exercise for
the student…
