I need to add a blank or dashed field to the
options_from_collection_for_select helper but can''t seem to get it to
work. Tried this, but with no effect:
<%= options_from_collection_for_select @airlines, ''id'',
''name''],
{:include_blank=>true} %>
Anyone know how to do this? Thanks,
-S

If you can use collection_select instead of
options_from_collection_for_select then this code works well for me
<% collection_select(:air, :id, @airlines, :id,
:airline_name, {:include_blank => true, :selected => nil})
%>

I don''t always want to use collection_select since I don''t always need the object/model bindings (i.e. in a search form). So this worked for me: <%= select_tag "some_select", "<option></option>" + options_from_collection_for_select(@foo, "id", "item") %> This works because options_from... returns a string of <option> tags. Just add a blank option tag on to the front of the string.
