使用 Active Record 的 Nested Attributes 機制提供 EAV 功能, 並且支援多語系的欄位名稱

在需要定義欄位的 Model 中添加, ex. 活動報名人表單

  acts_as_form_hosted
end

在紀錄資料的 Model 中添加

class User
  include DynamicFormInterface
  acts_as_form_interface :form
end

增加欄位範例

  @form.build_form_fields [ {type: :text, title:'新文字欄位'}, 
                             {type: :radio, :title: "性別", 
                              :custom_options_attributes => [ { :name => "male" }, { :name => "female" } ] 
                             }
                           ]

  @form.build_form_field {type: :text, :title => '新文字欄位'}
  @from.build_form_field {type: :radio, :title: "性別", 
                            :custom_options_attributes => [ { :name => "male" }, { :name => "female" } ] 
                          }

網頁中的表單範例

有提供了 render_input 這個 helper 顯示表單欄位

<%= form_for @user, :html => {:multipart => true} do |f|%>
    <% @user.form_fields.each do | field |%>
        <%=render_input @user, field%>
    <% end %>
    <%=f.submit%>
<% end %>
