Day name with I18n

Question

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

Date.today.strftime("%A")

How would I localize it?

I.e. "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"

Will work if you have the day_names in your translation file.

Answer 3

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

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