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

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) %> I went through the api docs

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).

I have a wizard which consists of two pages. To keep it simple let''s say that the first page asks the user to select a state from the drop down menu. In case the user doesn''t select any state, an error message needs to be displayed. Ideally I would like to do something like this. def new selected_value = params[:addevent][:state_id] if selected_value == "-1"

Is this difference between the 2 commands desirable? > x<-1:3 > class(x) NULL
