Collection_select and select_tag help


#1

I have created the following select box which works fine except for the
fact if you edit the item it defaults back to N/A instead of selecting
the correct location.

select_tag(“item[location_id]”, ‘N/A’ +
options_for_select(@locations.collect{|location| [location.name,
location.id]}))

Ideally, I want to do something like this (which selects the correct
value on edit):

f.collection_select(:locations, @locations, :id, :name) %>

but how can I add an extra blank option at the top like I did with
select_tag?

thanks!

The (optional) last argument to options_for_select is the value to be
preselected (ie something like item.location_id)
