Hi, What is the correct syntax for adding a prompt to a select_tag? I have this, which works as expected: <%= select_tag "author_id", options_from_collection_for_select(@authors, :id, :name, @selected_author) %> When I try and add a prompt, like this: <%= select_tag "author_id", options_from_collection_for_select(@authors, :id, :name, @selected_author), :prompt => "Please select" %> I just get: <select id="author_id" name="author_id" prompt="Please select"> <option value="1">Jim</option> ... However, adding a blank field works fine: <%= select_tag "author_id", options_from_collection_for_select(@authors, :id, :name, @selected_author), :include_blank => true %> Resulting in: <select id="author_id" name="author_id"> <option value=""></option> <option value="1">Jim</option> ... What am I missing? Ruby 1.9.2p0 Rails 3.0.5 -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

> Have you tried with "options"? > options = {:prompt => ''Please Select''}Just did, but didn''t work :-( The effect is unfortunately the same: <select id="author_id" name="author_id" prompt="Please Select"> <option value="1">Jim</option> ... -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Out of interest though, this passes "author_id" in the params as an empty string, so I have to write: if params.has_key?(:author_id) and not params[:author_id].empty? instead of just: if params.has_key?(:author_id) Does prompt pass any value in in the params? It would also be nice to understand why :prompt => true isn''t working. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
