无法在application.html.erb中调用实例的路径-Rails

[英]Can't call paths to instances in application.html.erb - rails

原文 2015-08-17 21:02:18 7 1 ruby-on-rails/ hyperlink/ routes/ views

但是，当我单击链接查看显示页面时，我在边栏上显示了元素的实例。 它抛出：

Items＃show中的NoMethodError

nil：NilClass的未定义方法“ each”

我的看法是这样的：

<% @items.each do |item| %>
      <%= link_to item.name, item %>
<% end %>

此外，当我在index.html.erb页面中使用这些链接时，它们会起作用。

1 个解决方案

检查您的@items var，看来它是nil，然后调用nil.each ...不起作用
