I''m trying to get a select box to populate with the current option for editing purposes. I can populate the box, but not with the currently selected value. I''ve read in the api where it says to do this: # Example with @post.person_id => 1: # select("post", "person_id", Person.find_all.collect {|p| [ p.name, p.id ] }, { :include_blank =>

The documentation states as an example: select("post", "person_id", Person.find_all.collect {|p| [ p.name, p.id ] }, { :include_blank => true }) could become: <select name="post[person_id]"> <option></option> <option value="1" selected="selected">David</option> <option

Hi, I''m using: select(object, method, choices, options = {}, html_options = {}) I''ve read the API where there''s this example: select("post", "person_id", Person.find_all.collect {|p| [ p.name, p.id ] }, { :include_blank => true }) should give this code: <select name="post[person_id]"> <option></option>

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).

Hi, I can do this : collection_select "state", :id, TrainingState.find_all,:id,:name but not this : collection_select "state[]", :id, TrainingState.find_all,:id,:name Anyone any idea why?

In case where a collection_select is selecting a required value for an object (a not null field), is it possible to set a generic default value for the select box? I have tried :prompt => true and :include_blank => true but neither changes the value for required fields. It does for non-required fields though. Thanks.
