Question

我正在使用Date.today.month来显示月份编号。是否有获取月份名称的命令，或者我是否需要提出案例来获取它？

Answer 1

Date::MONTHNAMES[Date.today.month]会给你“一月”。（您可能需要先require 'date'。

Answer 2

您也可以使用I18n：

I18n.t("date.month_names") # [nil, "January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"]
I18n.t("date.abbr_month_names") # [nil, "Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"]
I18n.t("date.month_names")[Date.today.month] # "December"
I18n.t("date.abbr_month_names")[Date.today.month] # "Dec"

Answer 3

您可以使用strftime：

Date.today.strftime("%B") # -> November

http://www.ruby-doc.org/stdlib-1.9.3/libdoc/date/rdoc/Date.html#strftime-method

Answer 4

如果你关心语言环境，你应该这样做：

I18n.l(Time.current, format: "%B")

Answer 5

对于Ruby 1.9，我不得不使用：

Time.now.strftime("%B")

Answer 6

HTML选择带有I18n的月份：

<select>
  <option value="">Choose month</option>
  <%= 1.upto(12).each do |month| %>
    <option value="<%= month %>"><%= I18n.t("date.month_names")[month] %></option>
  <% end %>
</select>

本月的名称（Date.today.month作为名称）
