Active Admin date filter date format customisation

Question

Is there simple way to change the ActiveAdmin date filter display format from the default ISO format (yyyy-mm-dd)?

Answer 1

Instead of overwriting the js you can provide extra options to the datepicker like this:

 = f.input :my_date, as: :datepicker, datepicker_options: { dateFormat: "mm/dd/yy" }

Answer 2

The way i fixed is is like this:

$ ->
  # reset format
  $('.datepicker:not(.hasDatepicker)').each ->
    if $(@).val().length > 0
      p = $(@).val().split('-')
      $(@).val("#{p[2]}-#{p[1]}-#{p[0]}")

  # change format
  $(document).on 'focus', '.datepicker:not(.hasDatepicker)', ->
    $(@).datepicker dateFormat: 'dd-mm-yy'

So first reset the value from yyyy-mm-dd to yyyy-mm-dd, than set the correct format on the picker.

Hope this helps someone.

This works in ActiveAdmin pre 1 with the just_datetime_picker gem
