Hi,
I need to observe a set of radio buttons but am having great trouble. My
observe_field looks like this:
<%= observe_field :user_select, :frequency => 0, :url => { :action
=>
:admin_control } %>
Now it works fine if I use a text_field like this:
<%= text_field :user, :select, "size" => 20,
"maxlength" => 16 %>
But I want a radio button, and what I have is this:
<%= radio_button("user", "select", user.id) %>
The above doesn''t work and neither does:
<%= radio_button_tag("admin", "select", user.id) %>
----------
I ahve no clue why the radio buttons don''t work with the observer. Any
help would be greatly appreciated!
Thanks,
Aditya

(Remember: "View source" is your friend.) So you want: <%= observe_field ''user_select_'' + @user.id, ... } %> (You also want user to be an instance variable for the radio button helper to create an appropriately-selected input.) -- We develop, watch us RoR, in numbers too big to ignore.
Mark, Thanks for the reply. Actually, I noticed in the page source that Rails adds the @user.id part in the ''id'' of the radio button. I tried your solution soon after posting my earlier message, but surprisingly it diidn''t work, although it created the same ''id'' as the text_field does :/ I think I''ve got it to wok by not using the radio_button method at all but simply using the HTML tag like this: <INPUT type="radio" id="user_select" name="user[select]" value=<%= user.id %> > Your solution should work though, don''t know why it doesn''t. -Aditya Mark Reginald James wrote:> Aditya Rajgarhia wrote: > >> <%= radio_button_tag("admin", "select", user.id) %> > The current API docs have not been updated to reflect the fact that the > radio button helper creates an input with an id of object_method_value > rather than just object_method.
