If you are looking solely to the month name, the Date::MONTHNAMESconstant provided by rails is the easiest solution for you:
如果您只查看月份名称，则Date::MONTHNAMESrails 提供的常量是最简单的解决方案：
Date::MONTHNAMES =
[
[ 0] nil,
[ 1] "January",
[ 2] "February",
[ 3] "March",
[ 4] "April",
[ 5] "May",
[ 6] "June",
[ 7] "July",
[ 8] "August",
[ 9] "September",
[10] "October",
[11] "November",
[12] "December"
]

If you want a localized month name, try:
如果您想要本地化的月份名称，请尝试：
I18n.t('date.month_names')[date.month]
Example:
例子：
I18n.t('date.month_names')[12] #=> "Dezembro"

If you have a particular custom date / time format which you need to use repeatedly then you can extend the ActiveSupport date / time helper.
如果您有需要重复使用的特定自定义日期/时间格式，那么您可以扩展 ActiveSupport 日期/时间助手。
e.g. if you define the following in your config/environment.rb
例如，如果您在 config/environment.rb 中定义以下内容
ActiveSupport::CoreExtensions::Time::Conversions::DATE_FORMATS.merge!(:full_english => "%A %B %d, %Y at %I:%M %p")
then when you call Time.now.to_s(:full_english)in your views you will get something like:
然后当你调用Time.now.to_s(:full_english)你的视图时，你会得到类似的东西：
"Friday June 11, 2010 at 12:53 PM"
