带有 I18n 的日期名称

Question

Without translation, this would get me today's day name:

Date.today.strftime("%A")

How would I localize it?

Ie "Mardi" if I18n.locale is set to fr .

Answer 1

You probably have in your locale file(s) the following:

# example with fr
fr:
  date:
    day_names: [Dimanche, Lundi, Mardi, Mercredi, Jeudi, Vendredi, Samedi]
#               ^^^^^^^^ a week starts with a Sunday, not a Monday

In order to get today's name, you could do:

week_day = Date.today.wday # Returns the day of week (0-6, Sunday is zero)
I18n.t('date.day_names')[week_day]

or eventually

I18n.l(Date.today, format: '%A')

Answer 2

l Date.today, format: "%A"

如果您的翻译文件中有day_names ，将起作用。

Answer 3

if you use rails-i18n , you will have the day names and month names already translated, eg:

I18n.l(value, format: "le %A %e %B à %-Hh%M")
# le Dimanche 19 Juillet à 21h00
