如何阻止该属性数组在我的视图中显示？ [英] How to stop this array of attributes from showing in my view?

问题描述

我遇到一个令人烦恼的问题，我的视图不断显示对象属性的数组！我的子菜单假设以树形形式显示类别，该类别有效，但它也显示了此烦人的数组！

I have an annoying problem where my view keeps displaying an array of my object's attributes! My submenu is suppose to show categories in a tree form, which works, but it also shows this annoying array!

[< #Category id：26，标题： subtest，描述：测试中的测试，testception，created_at： 2015-03-01 03:15:29，updated_at： 2015-03-03 01:08:09 ，祖先： 6/24>]

[ <#Category id: 26, title: "subtest", description: "a test within a test, testception", created_at: "2015-03-01 03:15:29", updated_at: "2015-03-03 01:08:09", ancestry: "6/24">]

[<＃类别ID：24，标题：测试，描述：不要惊慌，此只是一个测试。，created_at： 2015-03-01 02:06:35，updated_at： 2015-03-03 01:07:52，祖先： 6>]

[ <#Category id: 24, title: "Test", description: "No not be alarmed, this is only a test.", created_at: "2015-03-01 02:06:35", updated_at: "2015-03-03 01:07:52", ancestry: "6">]

我绝对不希望用户看到此内容。如何摆脱它？

I definately don't want the user to see this. How do I get rid of it??

Show.html.erb视图：

Show.html.erb view:

<div id="submenu">
  <%= render 'submenu_cats', categories: @category.root.children %>
</div>

_submenu猫部分：

_submenu cats partial:

<ul>
  <%= categories.each do |category| %>
    <li>
        <%= link_to_unless_current category.title, category_path %>
        <%= render 'submenu_cats', categories: category.children if category.children.present? %>
    </li>
  <% end %>

推荐答案

请勿使用...

<%= categories.each do |category| %>

使用

<% categories.each do |category| %>

当您使用<％= 时，您正在输出表达式的结果。 categories.each 的结果是 categories ，即正在输出的数组。您不想输出它，因此使用<％评估Ruby而不输出结果。

When you use <%=, you're outputting the result of the expression. The result of categories.each is categories, the array that is being output. You don't want to output it, so use <% to evaluate the Ruby without outputting the results.
