# I submitted a bug report https://github.com/rails/rails/issues/34244
# b/c Rails was not honouring my `rescue_from` block which was causing my API to
# be inconsistent. I was told this is expected behaviour. I think it's probably
# fine for an HTML app where you control the form inputs. But for an API app,
# the API is public facing and very important, so Rails shouldn't have its own
# special errors that bypass my app's configuration and make my API inconsistent.
# 
# Decided it shouldn't be too difficult to handle this myself. So, here is my
# solution. It contains most of the important lessons I've learned about how to
# get a Rails API app setup. It removes Rails' params parsing and adds its own.
