ruby on rails 视图中的渲染问题 [英] Rendering issue in views in ruby on rails

问题描述

视图中的代码应给出数据库中的书籍

The code in the view shall give the books in the database

<% @bookmark.each do |book| %> 

仅适用于多行.如果我有单行，它会显示像

works only for multiple rows. If i had single row, it would show error like

" undefined method `each' for #<Bookmark:0x3e2e3f0> "

我应该怎么做才能打印单行.?

What should i do to print single row also. ?

推荐答案

<% @array_bookmark = @bookmark.class == Array ? @bookmark : [@bookmark] %>
<% @array_bookmark.each do |book| %>
