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''ve also tried:
collection_select(:selectionfilter, :producer_id, Producer.find(:all),
:id, :name, {:include_blank => true}, {:selected_value =>
@initial_selection})
which likewise doesn''t work. I''ve verified that
@initial_selection is
returning the correct value.
The docs say that collection_select uses the
options_for_collection_select, which has :selected_value as one of its
options, so it seems the above should work, but I''m obviously missing
something.

Assuming that ''your model'' is related to producers, I would use it something more like this... (controller code) @producer = Producer.find(:all) (view code) <%= options = [[''Select'', '''']] + @producer.collect { |producer| [producer.name, producer.id] } select ''YOUR_MODEL'', ''producer_id'', options %> Craig

(It seems to me, my original code is a shortcut for the above.) The problem I''m having is not with the select box malfunctioning, but rather that the select box is not displaying the initial value that I want it to. It''s used to set a filter, and when the user selects a value, the page is refreshed, filtered on that value. At that point I would like the select box to display the last value selected (the value that is being filtered on), which I have stored in @initial_selection. However, despite using the ":selected" option, the select box still show the default first value. That''s what I''m trying to solve. In other words, my code is yielding this: <select id="selectionfilter_producer_id" name="selectionfilter[producer_id]"> <option value=""></option> <option value="1">Bob</option> <option value="2">Harry</option> <option value="3">John</option> when I want it to yield this (assuming the user chose "Harry" last time around). <select id="selectionfilter_producer_id" name="selectionfilter[producer_id]"> <option value=""></option> <option value="1">Bob</option> <option selected value="2">Harry</option> <option value="3">John</option> Any other clues?

Francois, I was having the same problem and found this: http://wiki.rubyonrails.org/rails/pages/HowtoUseFormOptionHelpers It worked for me, but remember that you may need to cast your initial_selection to an integer (ie @initial_selection.to_i) Hope it works, Andy -- ______________________________ Andrew Biller Broadcast television engineering Consultancy System design Technical support T: +44(0)7768 014 013 F: +44(0)8707 515 078 E: a.biller@ashho.co.uk -------------- next part -------------- An HTML attachment was scrubbed...

Francois, did you figure out a way to do this? Do you know how to set multiple options to be selected?
