狂欢活动菜单

Question

我想达到什么目的？

我正在尝试将活动菜单（在菜单中突出显示当前页面）添加到我在 rails 应用程序上的 spree/ruby。

我尝试了什么？

经过一些研究，我发现 this question posted very helpful, but as you might have guessed the implementation of the solution I found 没有得到我想要的结果。

我找到的解决方案是将以下代码添加到：

代码

application_helper.rb

module ApplicationHelper

 def active_class(link_path)
  current_page?(link_path) ? "active" : ""
 end

end

routes.rb

   root 'spree/home#home'

   get '/specs', to: 'spree/home#specs'
   get '/about', to: 'spree/home#about'
   get '/purchase', to: 'spree/home#purchase'
   get '/support', to: 'spree/home#support'

nav.html.erb

<li class="<%= active_class(root_path) %>">
<%= link_to "Home", root_path %>
</li>

<li class="<%= active_class(purchase_path) %>">
<%= link_to "Purchase", purchase_path %>
</li>

<li>
<%= link_to "About", purchase_path %>
</li>

<li class="<%= active_class(specs_path) %>">
<%= link_to "Technical Details", specs_path %>
</li>

<li class="<%= active_class(support_path) %>">
<%= link_to

错误

但是现在，无论我转到哪个页面，我都会收到以下错误：

NameError in Spree::Home#purchase
Showing /home/ubuntu/workspace/mystore/app/views/spree/shared/_nav_bar.html.erb where line #9 raised:

undefined local variable or method `purchase_path' for #<#<Class:0x007f35a30c6b80>:0x007f35a3642a00>
Extracted source (around line #9):


</li>

<li class="<%= active_class(purchase_path) %>">
<%= link_to "Purchase", purchase_path %>
</li>

我试过更改几个变量，但无济于事

我的问题是:

如何在 Spree 中创建活动菜单（因为这是问题的根源）

Answer 1

请参阅下面的参考资料。我使用激活而不是激活。您可以在

之后设置激活的 class 样式

<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
        <ul class="nav navbar-nav navbar-right" id="link-section">
            <li class="<%= 'activated' if current_page?(root_path) %>">
                <a href="/">Home
                    <span class="sr-only">(current)</span>
                </a>
            </li>
            <li class="<%= 'activated' if current_page?(new_user_registration_path) %>">
                <%= link_to("Register", new_user_registration_path) unless user_signed_in? %>
            </li>
            <li class="<%= 'activated' if current_page?(pricing_path) %>">
                <%= link_to("Pricing", pricing_path) %>
            </li>
            <li class="">
                <% if current_user %>
                    <%= link_to("Store", shop_path(current_user.shop)) if current_user.shop.present? %>
                <% end %>
            </li>
            <li class="<%= 'activated' if current_page?(new_user_session_path) %>">
                <%= link_to("Login", new_user_session_path) unless user_signed_in? %>
            </li>
            <li class="<%= 'activated' if current_page?(dashboard_path) %>">
                <%= link_to("Dashboard", dashboard_path) if user_signed_in? %>
            </li>
            <li>

            </li>
        </ul>
    </div>
