Rails date format in a text_field

Question

I have a rails form that displays a date in a text_field:

<%= form.text_field :check_in_date  %>

The date is rendered as yyyy-m

Answer 1

A slight improvement of Tom Rossis answer is to use the I18n.localize method, so the default will always be in the current users locale:

initializers/date_time_i18n_formatter.rb

Date::DATE_FORMATS[:default] = ->(date) { I18n.localize date, format: :default }
Time::DATE_FORMATS[:default] = ->(time) { I18n.localize time, format: :default }
