Question

我的应用程序正在调用资源问题路径助手show_popular_hashtags_path，但Rails似乎无法识别它。这是我的偏爱：

.col-xs-12.no-padding.blue-title{style: "page-break-inside: avoid !important;"}
  .col-xs-12.text-center.global-map.no-padding
    %h1 
      = t('uniq.hashtag.title')
    .js-column-chart-hashtags{data: {url: show_popular_hashtags_path(id: @project.id, provider: provider), provider: provider}}
      .column-chart-hashtags.statistics-chart{class: "#{provider}", style: "width: 100%"}
    %h2.empty-message.column-chart-hashtags{class: "#{provider}", style: "padding-top: 15px; padding-bottom: 30px; display: none;"}
      = t('unique.there_is_no_info')

这是我的routes.rb：

namespace :user do
  resources :projects, except: [:delete] do
    member do
      get :show_users, to: 'projects#js_show_users_data', as: :show_users_data
      get :show_popular_hashtags, to: 'projects#js_show_popular_hashtags', as: :show_popular_hashtags
      get :show_activity_data, to: 'projects#js_show_activity_data', as: :show_activity_data

对于其他路线，一切都很顺利，即使我运行rake routes | grep show_popular_hashtags，输出也是：

$ rake routes | grep show_popular_hashtags
    show_popular_hashtags_user_project GET      /user/projects/:id/show_popular_hashtags(.:format)       user/projects#js_show_popular_hashtags

所以，这看起来路线很好，但是当我访问包含部分的视图时，会出现此错误：

undefined method `show_popular_hashtags_path' for #<#<Class:0x007fa20d865d10>:0x007fa20dc5a6f0>

我已经重新启动了服务器，但它没有用。

路线助手的名称实际上是show_popular_hashtags_user_project，而不是show_popular_hashtags。您可以在rake routes输出的第一列中看到它：

$ rake routes | grep show_popular_hashtags
    show_popular_hashtags_user_project GET      /user/projects/:id/show_popular_hashtags(.:format)       user/projects#js_show_popular_hashtags

只需在视图中将show_popular_hashtags路线助手的名称更改为show_popular_hashtags_user_project即可。

路径无法识别Rails
