// This snippet is a customized version of the code found on
// stackoverflow. Since firefox only copies to the clipboard when the event
// was triggered by a user, I had to add the button to the top of the page.
// In chrome it might work without the need for a button, directly from a
// bookmarklet. See the following for more information.

Live stream a database dump (or any other STDOUT) using Rails 4. Why would you want this? If you have a large database dump and want to avoid storing it in memory as Rails streams it. This allows pipe the dump directly into the http response instead of storing it as a file, sending it, and then deleting it. Let me know what you think! I've teste…
class DatabaseController < ApplicationController
def database_dump
database = Rails.configuration.database_configuration[Rails.env]["database"]
send_file_headers!(:type => 'application/octet-stream', :filename => "#{database}_#{Time.now.to_s(:human)}.backup")
pipe = IO.popen("pg_dump '#{database}' -F c")
stream = response.stream
while (line = pipe.gets)
stream.write line
sleep 0.0001 # HACK: Prevent server instance from sleeping forever if client disconnects during download

Makes attr_accessible whiny. A monkey patch for Rails 3.1 to raise an exception instead of a warning in the logs when protected fields are mass assigned
# Rails edge includes pluggable sanitizers for mass assignment. Really cool is the
# StrictSanitizer which raises an exception instead of a log message, which makes
# problems easier to spot in development.
# For the time being, there seems to be no way to achieve this in Rails 3.1 via
# configuration. Monkey patching to the rescue!
# Copy the gist into config/initializers and configure the environments in which the
# exception gets raised.
