升级ERb标签以进行Rails 3升级.我应该:<％=结束％>也一样 [英] Upgrading ERb tags for Rails 3 upgrade. Should I: <%= end %> as well?

问题描述

给出一个rails 2.3.x ERb代码块:

Given a block of rails 2.3.x ERb code:

<% form_for account, :url => { :action => :invite } do |f| %>
  # blah
<% end %>

使用Rails升级插件，它告诉我需要将<%替换为<%=，我是否也应该对end行执行此操作?如:

using the Rails upgrade plugin, it tells me that I need to replace <% with <%= should I also do this for the end line? Such as:

<%= form_for account, :url => { :action => :invite } do |f| %>
   # blah
<%= end %>

推荐答案

否，开始块时只需要<％=.

No, you would only need <%= when you start a block.

应该是:

<%= form_for account, :url => { :action => :invite } do |f| %>
   # blah
<% end %>

请参阅此 rails/asciicast 以升级到新版本erb.

See this rails/asciicast for upgrading to the new erb.
