You

Is there a trick to validating select menus? I have this rule: validates_presence_of :title, :type :title is a text box and validates correctly but :type doesn''t: <p> <label for="resource_type">Type</label><br/> <select name="resource[type]" id="resource_type"> <option value=""

It seems like it takes me hours to figure out something that I could have written in pure code in minutes. The select_month and select_day helper has been my latest waste of time. All I''m trying to do is add

Folks, I think I should start a new thread for this, because a similar one I saw is a bit old and the resolution there doesn''t seem to apply to what I''m running into now. Anyway, my date_select calls are bombing on me with the exception: ---- ActionView::TemplateError (wrong number of arguments (3 for 2)) on line #8 of entries/_dates_form.haml: 8: = date_select(
