我正在学习 Rails，我正在做一个练习，我必须在视图文件中混合一些 html 和 ruby​​.

I'm learning Rails, and i'm doing a exercise which i have to mix some html with ruby in a view file.

What is the main difference between " <%= #code %> " and " <% #code %> ", when coding ruby?

推荐答案

<%= something which you would like to have displayed in your view %>
<% something you would like to have hidden, 
(or something which doesn't display anything in the view) such as a
 conditional statement %>

<% if @post.nil? %>
    <%= render "nilNotify" %>
<% else %>
    <%= @post.content %>
<% end %>
