# Overrides Rails file activerecord/lib/active_record/schema_dumper.rb to
# include all schema information in the db/schema.rb file, for example, in the
# create_table statements. This allows for a working development database
# to be built from a schema.rb file generated by rake db:schema:dump.
#
# This is essentially a rebuild of the "schema_plus_multischema" gem (which is
# unfortunately only compatible with Rails ~> 4.2).
#
# Tested with Rails 6.0.

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

Some CoffeeScript (verbosely commented for clarity)

# Override Rails handling of confirmation

$.rails.allowAction = (element) ->
  # The message is something like "Are you sure?"
  message = element.data('confirm')

Why?

There is a long standing issue in Ruby where the net/http library by default does not check the validity of an SSL certificate during a TLS handshake. Rather than deal with the underlying problem (a missing certificate authority, a self-signed certificate, etc.) one tends to see bad hacks everywhere. This can lead to problems down the road.

From what I can see the OpenSSL library that Rails Installer delivers has no certificate authorities defined. So, let's go fetch some from the curl website. And since this is for ruby, why don't we download and install the file with a ruby script?

Installation

The Ruby Way! (Fun)
