Ruby on rails 如何提交两份带有一个按钮的表格3

我想用一个按钮提交两份表格

以下是我的代码：-

利率.rb

belongs_to :target, :polymorphic => true
belongs_to :location

has_many :rates

has_many :rates, :as => :target

位置.rb

belongs_to :target, :polymorphic => true
belongs_to :location

has_many :rates

has_many :rates, :as => :target

event.rb

belongs_to :target, :polymorphic => true
belongs_to :location

has_many :rates

has_many :rates, :as => :target

form.html.haml

= form_for [@event, @rate] do |form|
                    %ul
                        %li= form.radio_button :rate, "Excellent"
                        %li Excellent
                        %li= form.radio_button :rate, "Okay"
                        %li Okay
                        %li= form.radio_button :rate, "Poorly organized"
                        %li Poorly organized
                        %li= form.radio_button :rate, "Didn't happen"
                        %li Didn't happen

=form_for [@event.location, @rate] do |form|
                    %ul
                        %li= form.radio_button :rate, "Excellent"
                        %li Excellent
                        %li= form.radio_button :rate, "Okay"
                        %li Okay
                        %li= form.radio_button :rate, "Nothing special"
                        %li Nothing special

如何做到这一点？

我今天也遇到了同样的情况，我做到了：

在form.html.haml中添加一个链接：（我用ERB写的）

就这样

如果不通过AJAX提交至少一个表单，您就不能这样做。AJAX解决方案是什么？不清楚您为什么要这样做。看看insteadnested属性，如果我有一个模型引用两个模型，那么嵌套属性就会起作用，例如：-event有多个：rates，：locations，那么我可以使用字段，在我的例子中可以使用字段吗？
