# We need this method to ensure the form object will always have an ID,
# and thus its `to_param` method will always return a significant value.
# If we remove this method, get an error onn the `update` action and try
# to resubmit the form, the form will not hold an ID, so the `to_param`
# method will return an empty string and Rails will treat this as a
# `create` action, thus raising an error since this action is not defined
# for the controller we're using.
#
# TL;DR: if you remove this method, we'll get errors, so don't.
