I have the following snippet in my app:
<% @anitem = Item.find(:all, :conditions => "id = " +
params[:id]) %>
<% form_for :anitem, :url => { :action => :updateitem } do |thisform|
-%>
...
... (some code...removed)
...
<%= collection_select :thisform, :item_category,
ItemCategory.find(:all), :id, :name %><br>
<%= collection_select :thisform, :packing_list_type,
PackingListType.find(:all), :id, :name %>
<%= submit_tag ''Update'' %>
<% end %>
My issue is that the list box never selects the current value when it
pulls the data from the database.
Everything looks great - but no currently selected option tag
("selected").
Should be easy, but I can''t get it to work.
Any ideas?

Well the documentation shows an example of how to select an element: http://api.rubyonrails.org/classes/ActionView/Helpers/FormOptionsHelper.html#M000928 Do a view source and see if there is "selected" for an option. Put a debug statement and look at the log file to check if there is any value that is returned by the db.

> > When using the form_for stuff you need to do > thisform.collection_select :field_name,... >Thanks, Fred. Couldn''t get that to work. I tried various permutations. I am using this, and it works, but it''s a hack of sorts: <%= select(:aform, "packing_list_type_id", PackingListType.find(:all).collect {|p| [ p.name, p.id ] }, {:selected => @anitem[0][''packing_list_type_id'']}) %> It uses the :selected thingy to make it all work. - tedstur -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
