ruby-on-rails – fields_for中的数组列字段呈现…未呈现

没有按预期呈现…请找你的建议.

守则如下：

资源迁移有：

t.string :news_outlets,array: true

父帖子的_form.html

<%= form_for [@post,@post.declare_victory],:html => {} do |f| %>
  <%= f.hidden_field :post_id,value: @post.id %>
  <%= f.fields_for :news_outlets do |news_outlet| %>
   <%= render 'news_outlet_fields',f: news_outlet %>
   <div>
   <%= link_to_add_item t('add_news'),news_outlet,'/news_outlet_fields','news_outlets'%>
  </div>
 <% end %>
<% end %>

DeclareVictory中的控制器操作

def create
 @declare_victory = @post.build_declare_victory declare_victory_params
 @declare_victory.user = current_user
 @declare_victory.save

 redirect_to @post,notice: t('success')
end

_news_outlet_fields.html部分呈现

<div class="form-group">
 <%= f.text_field '',id: 'declare_victory_news_outlets',:class => 'form-control',:placeholder => t('news_outlets.new_news') %>
</div>

谢谢
