我用下面的代碼獲取錯誤集合中選擇,不能使用默認值,它
<%= f.collection_select :location_id, Location.all, :id, {:selected => session["location"]},:formatted_display, { prompt: true }, :required => true, :class => 'chosen-select order_form' %>
我收到以下錯誤,當我嘗試上述默認值:
wrong number of arguments (7 for 4..6)
我已經得到了同樣的錯誤數量的參數錯誤 – Aravind
的它的工作原理與此編輯 '<%= f.collection_select:location_id,Location.all,:id,:name,{:prompt => true,:selected => session [「location」]},:class =>'chosen-select order_form 「%>' – Aravind
