I have previously written about a really great Ruby gem called RailsAdmin which allows you to quickly prepare admin dashboards from your models. However, it comes with a disadvantage when you are dealing with large files. Let’s say that you want to export a large file from your RailsAdmin, like having 100 000 rows. This export will take a while and if you are using Heroku, chances are that you will actually have a timeout. Luckily, here comes ActiveAdmin.
