我的
中有以下代码new.html.erb
<%= form_tag puppies_path do %>
<% @kennel.each do |puppy| %>
<%= fields_for 'puppies[]', puppy do |p| %>
<div class="field">
<%= p.label :name %><br>
<%= p.text_field :name %>
</div>
<div class="field">
<%= p.label :breed %><br>
<%= p.text_field :breed %>
</div>
<% end %>
<% end %>
<div class="actions">
<%= submit_tag %>
</div>
<% end %>
而puppies []数组变量,应该将对象数组发布到控制器,只发布单个对象。请帮助将数组发布到控制器。提前谢谢!

fields_for
的常规设置是这样的。
<% @kennel.each do |kennel| %>
<%= fields_for :puppies, @kennel.puppies do |p| %>

是的,我刚刚找到答案......
在new.html.erb文件中
<%= form_tag puppies_path do %>
<% 2.times do %>
<%= render 'puppies_group_form' %><br>
<% end %>
<%= submit_tag "Submit" %>
<% end %>
在_puppies_group_form
中
Name <%= text_field_tag "puppies[][name]" %>
Breed <%= text_field_tag "puppies[][breed]" %>
