I tried to do it by myself,
I've a model named Entry with a field named type_id (added via migration) and a model named EntryType with a field named description.
class Entry < ActiveRecord::Base
belongs_to :entry_type
...
end
class EntryType < ActiveRecord::Base
has_many :entries
end
I added the following code line to my /_form.erb:
<%= f.select('entry', 'type_id', EntryType.all.collect {|t| [t.description, t.id]}, {:include_blanks => 'None'}) %>
but when I try to load the page I get this exception:
