我不记得代码,如何以嵌套形式(通过简单形式)创建新对象。它类似于:“某物:new_object ...”
谢谢
通常使用:
<%= f.fields_for :object do |builder| %>
但是您可以使用simple_fields_for,如下所示:
form_for @user do |f|
f.simple_fields_for :posts do |posts_form|
# Here you have all simple_form methods available
posts_form.input :title
end
end
参考:http ://simple-form.plataformatec.com.br/#usage/extra-helpers
它最初使用form_for,但请检查此线程:simple_form 中的嵌套属性返回质量分配错误
感谢保管箱,我找到了它..
您需要将此添加到您的 javascript(在 CoffeScript 中)
#= require jquery_nested_form
这就是形式(在 HAML 中)
= simple_nested_form_for @variable do |f|
= f.input :code
// Link to create new empty object
= f.simple_fields_for :nested_attributes do |s|
= f.link_to_add "Add new", :nested_attributes
= s.input :name
= s.input :locale
// Link to remove
= s.link_to_remove 'Remove'
= f.button :submit
