Ruby Rails collection select is displaying blank "prompt" value?

Question

I have a collection select like the following:

<%= f.collection_select :region_id, Region.find(:all), :id, :name, { :prompt => 'Select a State/Province' }, :style => "width: 200px;" %>

Sometimes the prompt from the :prompt option appears, but sometimes it does not. Does anyone know where I could begin to troubleshoot this? Maybe I have been looking at it too long...

Answer 1

Instead of

:prompt => "Select a State/Province"

try

:allow_blank => "Select a State/Province"

EDIT: Yes after checking the API I can see that I had it confused, prompt is the correct way according to the documentation, could it be that it only sometimes it appears because your object has a value already and therefore the prompt is there but it is not the currently selected value in the drop down list???

Answer 2

:include_blank with the value of your blank option seems to do the trick eg. {:include_blank => "Please select"}
