为什么to_date在我的视图输出日期中的格式与Rails控制台中to_date的格式不同？

In my view, I do this:

在我看来,我这样做:

  <td><%= client.last_contact.to_date %></td>

That outputs this:

这输出:

2011-08-11

But when I do it in the console, I get the format I want:

但是当我在控制台中执行此操作时,我得到了我想要的格式:

1.9.3p194 :093 > c.last_contact
 => Thu, 11 Aug 2011 00:00:00 UTC +00:00 
1.9.3p194 :094 > c.last_contact.to_date
 => Thu, 11 Aug 2011

In my view, I want it to display the day and the format that it does in the console.

在我看来,我希望它显示它在控制台中的日期和格式。

How do I achieve that?

我如何实现这一目标?

Thanks.

The best way to display time/date in rails views is using I18n localization feature. You can set datetime formats in your config/locales directory in yaml file. Something like this

在rails视图中显示时间/日期的最佳方法是使用I18n本地化功能。您可以在yaml文件的config / locales目录中设置日期时间格式。像这样的东西

# config/locales/datetime.en.yml
en:
  time:
    formats:
      # Use the strftime parameters for formats.
      # When no format has been given, it uses default.
      # You can provide other formats here if you like!
      default: "%d.%m.%Y"
      short: "%d %b"
      long: "%d %B %Y"
      date: "%a, %d %b %Y"

Then use l helper in your views

然后在视图中使用l helper

<%= l client.last_contact, :format => :date %>

The console calls inspect on values whereas erb tags call to_s on their value.

控制台调用值来检查值,而erb标签调用值的on_s。

While you could call inspect in your view, I'd encourage you to either use strftime which allows you to define precisely what you want

虽然您可以在视图中调用inspect,但我建议您使用strftime来准确定义您想要的内容

Date::today.strftime('%a, %d %b %Y')`

or use the I18n.localize helper (aliased to l) which allows you to define formats and reuse them

或使用I18n.localize助手(别名为l),它允许您定义格式并重复使用它们

I18n.localize Date::today, :format => :long
