ActiveAdmin filter date format

Question

Using Rails 6 and ActiveAdmin 2.6, how would I change the time formatting of a date field? More specifically, I have

filter :birthday

for my resource. This results in two datepicker input fields, allowing me to filter for records with a birthday between these two dates. What I want is to format these input values in dd.mm.yyyy, instead of the default yyyy-mm-dd. How can I achieve this?

Answer 1

The solution I found was to add the following to active_admin.js:

$(function() {
  $('.datepicker').on('focus', function() {
    $(this).datepicker('option', 'dateFormat', 'dd.mm.yy');
  });
});
