我一直坚持这个问题一个星期。如果你能搞清楚的话，我会给你寄一瓶苏格兰威士忌。说真的，它来贿赂。
在taxons#show我正在渲染产品部分_products.html.erb，它将表格中的所有产品列出到分类单元控制器的show视图中。当您点击某个产品时，默认情况下该应用会将用户重定向到products#show，其中_cart_local.html.erb部分呈现为显示'添加到购物车'选项。
但是在taxons#show上，当点击产品时，我会调出一个灯箱，这样用户就不必离开页面了。灯箱代码位于_products.html.erb内，我正在尝试在灯箱内呈现_cart_form.html.erb。当我这样做时，我得到'堆栈级别太深'错误，而taxons#show将无法呈现。
但购物车在products#how中呈现正常。我将部分@product更改为product。这没有用。我渲染了一个空的部分并加载了页面，这让我觉得问题出在_cart_local上（但为什么会在products#show呈现？）。
然后我取出了开始表单标签和结束的div / end标签之间的所有代码，并且还渲染了页面，这让我认为它在那个块中，但我不能再进一步了解它。我被困了
以下是_cart_local的代码，如果我在<!-- Here -->和<!-- AND HERE -->条评论之间取出代码，则页面呈现：
<%= form_for :order, :url => populate_orders_path do |f| %>

product.variants.active(current_currency).each_with_index do |v,index|
next if v.option_values.empty? || (!v.in_stock && !Spree::Config[:show_zero_stock_products])

如果您还有其他需要，请告诉我。我很感激。
这是帮助者的链接，也许问题在那里？ https://github.com/spree/spree/tree/v1.3.2/core/app/helpers/spree
答案 0 :(得分：1)
在_products.html.erb部分更改中：
<%= render 'spree/shared/cart_local', :locals => {:product => product} %>
到那个：
<%= render partial: 'spree/shared/cart_local', :locals => {:product => product} %>
问题应该解决。
为什么呢？因为按照您的方式执行此操作不会将locals转换为部分错误，这就是您收到错误的原因，请通过删除locals来自行检查。当然最有趣的部分是你在这里遇到stack level too deep错误的原因，但我现在无法找到答案。
哦，调试器是你的朋友;）
