Rails - May 2008 - Begginer question: how to edit using options_from_collection

Hi,

I have been stuck on this problem for 2 hours and still have no idea how
to do it. Basically I have a relationship between Workout and Exercise

Exercise has many Work out

anyway in my code at Workout.view the edit.html that was generated
through scaffold I wrote this

<% form_for(@workout) do |f| %>
<p>
  <b>Exercise</b><br />
  <%= select_tag "exercise",
  options_from_collection_for_select(Exercise.find_all, "id",
"name",
@workout.exercise_id) %>
  </p>
    <%= f.submit "Update" %>
  </p>
<% end %>

For some reason it does not update when I click it. I don''t have any
errors but it just doesn''t update. Does anyone know why?

Any help would be apperciated. Thanks

Kane

What doesn''t update when you click on what?

If I had to guess, I''d say that your workout record isn''t
updating
when you click on the update button because you''re using
"select_tag"
instead of "f.select", so your exercise information shows up in
params[:exercise] instead of params[:workout][:exercise].  You''re
probably saving your workout record based on params[:workout], so it''s
not getting the exercise info.
