collection_select question
How do I specify which option should be initially selected when using
the collection_select command? I''ve tried:
collection_select(:selectionfilter, :producer_id, Producer.find(:all),
:id, :name, {:include_blank => true, :selected_value =>
@initial_selection})
However it doesn''t return the desired results (the option with the value
of @initial_selection selected).

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 with multiple options
Hi,
I have built a select field that allows multiple options selected with
collection_select and "multiple"=>"multiple". How do I go about
receiving the values? If I use a variable name like collection[], it
complains that I can''t use @collection[] as the instance variable.
TIA

collection_select and selected_value
Hi,
I am using collection_select to build a drop down list. I would like
to have the current value selected. How can I do that?
My current code is straight from the example in Pragmatic Programmers
book [2nd ed, p480] copying here for reference.
<%=
@users = User.find(:all, :order => "name" )
form.collection_select(:name, @users, :id, :name)
%>

Collection_Select not showing Selected option
Hi, I''m having some problem with getting collection_select to return
the current value when editing a record. According to everything I''ve

Custom method in Application Controller
Hi All,
I took this idea Christian Hellsten and Jarkko Laine''s "Beginning Ruby
on Rails E-Commerce".
Here is the situation. I will be using the
"options_from_collection_for_select" and "collection_select" form helper
methods in my view to render drop-down selection lists for City and
State that have corresponding city_id and state_id foreign key
