This is the view municipalities.js.erb I have:
<% list_opt = options_from_collection_for_select(@municipalities, :id,
<% puts list_opt %> #ok! list_opt contains the options
$(’#municipality_id’).html(’<%= list_opt %>’);
and this is the combobox in the view:
if instead of ‘<%= list_opt %>’ I manually assign the string
'AlagnaAlbano AliceCastello Arborio ...' into list_opt then the combo municipality_id correctly works, if I use options_from_collection_for_select doesn't works (empy combobox) but that string is the same of options_from_collection_for_select
then why doesn’t work ?
