我有一个简单的部分：
<div class="gallery">
<a href="#" class="icon-left-arrow"></a>
<ul>
<% if products.any? %>
<% products.each do |product| %>
<li>
<%=link_to small_image(product)%>
<div class="product-info">
<p class="product-name">Product name</p>
<p>optional Brand/ Artist</p>
</div>
</li>
<% end %>
</ul>
<% end %>
<%= link_to '', taxonomy_preview_path %>
</div>
以下路线：
Rails.application.routes.draw do
#namespace Oklahoma
match 'account/paymentmethod/:cc_type/:id', to:'user_payment_methods#show', via:[:get], as: 'user_payment_methods'
#end
namespace :api do
api_version(module: "V1", header: {name: "Accept", value: "version=1"}, path: {value: "v1"}) do
match 'api/search/products/:query.json', to: 'search_api#query', via:[:get], as: 'search_api'
match 'api/search/products/prefetch.json', to: 'search_api#prefetch', via:[:get], as: 'search_api_prefetch'
#get '/taxonomy_preview', to: 'search#taxonomy_preview', as: 'taxonomy_preview'
end
end
get '/taxonomy_preview' => 'search#taxonomy_preview', as: 'taxonomy_preview'
end
我得到一个NoMethodError ......这个应该工作......当我进入控制台并且包含Rails.application.routes.url_helpers时，奇怪的是，定义了taxonomy_preview_path。有什么想法吗？
耙路线输出：
taxonomy_preview GET /taxonomy_preview(.:format) search#taxonomy_preview
错误消息：

通过引用main_app修复了这个问题。[路由名称] _path ...这可能与我在/...上安装另一个引擎（Spree）的事实有关。
