Question

Hello RoR程序员，

我被卡在定制的狂欢应用程序代码中，在升级到rails 5.1.5后出现错误。

puma记录了这个错误：

故障安全响应期间出错：没有路由匹配{：action =＆gt;“show”，   ：controller =＆gt;“spree / taxons”，：id =＆gt; nil}，可能无法比拟   约束：[：id]

应用程序/控制器/礼包/ taxons_controller.rb：

module Spree
  class TaxonsController < Spree::StoreController
    helper 'spree/products', 'spree/taxon_filters'

    respond_to :html

    def show
      @taxon = Taxon.friendly.find(params[:id])
      return unless @taxon

      @searcher = build_searcher(params.merge(taxon: @taxon.id, include_images: true))
      @products = @searcher.retrieve_products
      @taxonomies = Spree::Taxonomy.includes(root: :children)

热潮/前端/配置/ routes.rb中：

  # route globbing for pretty nested taxon and product paths
  get '/t/*id', to: 'taxons#show', as: :nested_taxons

在spree / core / app / helpers / spree / base_helper.rb中：

def seo_url(taxon)
  spree.nested_taxons_path(taxon.permalink)
end

第79行：spree.nested_taxons_path(taxon.permalink) method_missing' or undefined method永久链接'为零：NilClass

自定义_main_nav_bar.html.erb文件代码，从第16,14,13行开始记录错误：

<% @taxonomies ||= Spree::Taxonomy.includes(root: :children)  %>
<% max_level = Spree::Config[:max_level_in_taxons_menu] || 1 %>
<div class="navbar-header">
      <div class="container">
         <nav class="navbar" id="cssmenu">
          <ul class="navbar-nav">
            <li id="home-link"
            class="<%= ('active' if @page.nil? && @taxon.id == 12) unless @taxon.nil? %>"
              data-hook><%= link_to Spree.t(:home), spree.root_path %></li>

            <%#= @taxon.inspect %>
            <% @taxonomies.each do |taxonomy| %>
              <% cache [I18n.locale, taxonomy, max_level] do %>
                    <% taxonomy.root.children.each do |taxon| %>
                      <li class="<%= (taxon.id == @taxon.id ? 'active' : '') unless @taxon.nil? %>">
                        <%= link to taxon.name, seo_url(taxon) %>">
                        </a>
                      </li>
                    <% end %>
                <% end %>
            <% end %>
          </ul>

        </nav>

第12行：

<% @taxonomies.each do |taxonomy| %>

第13行：

<% cache [I18n.locale, taxonomy, max_level] do %>

第14行：

<% taxonomy.root.children.each do |taxon| %>

第16行

<%= link to taxon.name, seo_url(taxon) %>

在块（3级）中，puma寻找'seo_url'到spree_core-3.4.4 / app / helpers / spree / base_helper.rb：79'spree.nested_taxons_path（taxon.permalink）'方法丢失。

main_nav_bar.html.erb在rails 4.2上工作。

感谢任何帮助。

尝试这条路线：

 get '/t/*id', to: 'spree/taxons#show', as: :nested_taxons

没有路线匹配{：action =＆gt;“show”，：controller =＆gt;“spree / taxons”，：id =＆gt; nil}
