model, like so:

collection_select default selected value
Hiall,
Unfortunately I just can''t find out how to setup a default selected
value when using collection_select. My call is like so:
<%= collection_select(:consultant, :lastname, @consultants, :id,
:lastname, { :selected => @current_consultant.id } ) %>
which is not working, I debugged so far that I know that
@current_consultant.id contains the correct value.
Any tips?
cheers

collection_select to display 2 fields
I''m trying to get a collection_select generated Drop-down box to display
two fields from a table (first name & last name); however, I am having
trouble concatenating the symbols. It appears as though any code I put
in the 5th argument for collection_select is processed prior to
executing the collection_select method. The code executes successfully
with 1 symbol in the 5th

Setting an index on a collection_select
