Question

我有这段代码

 <%= semantic_form_for @tournament do |f| %>
    <%= f.semantic_fields_for :courts do |builder| %>
        <%= render :partial => "court_fields", :locals => { :f => builder } %>
        <span class="links">
         <%= link_to_add_fields "Add More Court", f, :courts %>
        </span>
    <% end %>

这是部分

<div class="nested_fields">
<%= f.input :name %>
<%= f.input :address %>
<%= f.input :city %>
<%= f.input :state %>
<%= f.input :zip %>
<%= f.input :phone %>
<%= f.input :contact_name %>
<%= link_to_remove_fields "Remove Court", f %>
</div>

但我真正需要的是还有部分的跨度，所以它封装在nested_fields div中......我试过了

<%= semantic_form_for @tournament do |f| %>
    <%= f.semantic_fields_for :courts do |builder| %>
  <%= render :partial => "court_fields", :locals => { :f => builder, :original_f => f } %>
<% end %>

和部分

<div class="nested_fields">
<%= f.input :name %>
<%= f.input :address %>
<%= f.input :city %>
<%= f.input :state %>
<%= f.input :zip %>
<%= f.input :phone %>
<%= f.input :contact_name %>
<%= link_to_remove_fields "Remove Court", f %>
<span class="links">
 <%= link_to_add_fields "Add More Court", original_f, :courts %>
</span>
</div>

但是我在下面得到了这个错误...我做错了什么，也许我对部分的理解是关闭的，任何帮助都会受到赞赏...

undefined local variable or method `original_f' for #<#<Class:0x000001035d5a80>:0x000001035cd920>

我的助手

def link_to_remove_fields(name, f)
  f.hidden_field(:_destroy) + link_to_function(name, "remove_fields(this)")
end

def link_to_add_fields(name, f, association)
  new_object = f.object.class.reflect_on_association(association).klass.new
  fields = f.fields_for(association, new_object, :child_index => "new_#{association}") do |builder|
    render(association.to_s.singularize + "_fields", :f => builder)
  end
  link_to_function(name, ("add_fields(this, \"#{association}\", \"#{escape_javascript(fields)}\")"))
end

Answer 1

render(association.to_s.singularize + "_fields", :f => builder)

部分渲染中没有original_f吗？

如何将两个值传递给partial
