How to display in a text field a date with format “dd/mm/YYYY”?

Question

I need to display in a text field a date with format "dd/mm/YYYY". I tried include the following in en.yml:

  date:
    formats:
      default: "%d/%m/%Y"

and

<%= f.date_field :date, value: t(:date)%>

But does not works.

Also I tried add a file called date_format.rb in initializers folder with the code:

Date::DATE_FORMATS[:default] = "%d/%m/%Y"

But nothings happens

How can I do this?

Note: I'm using Rails 4.

Answer 1

你应该试试

t.strftime("%d/%m/%Y")

Answer 2

You can try localizing the date with:

l(date)

and to get the shorter version:

l(date, format: :short)

In case you need to be able to display and edit a date in a form, you could try simple_form or formtastic and then display the date field:

<%= f.input :date, as: :date %>

This should automatically convert your date in the default format for the current locale.

Answer 3

It's not t (I18n.translate) you should use.

It's l (I18n.localize) instead.

So just do <%= f.date_field :date, value: l(f.object.date)%>

Answer 4

<%= f.date_field :date, value: t.strftime("%m/%d/%Y")%>
