1.1 The Application Template: (Think layout.html.erb)

Regex replacements in postgres

I had to make a simple change to all the strings in a table, and I was dreading having to load them into memory, iterate over them, searching for the string, and updating replacements. So instead, I learned that postgresql can actually do regex replacements in an update statement.

For example, if I have a links table with a url column with a bunch of URLs erroneously ending in "?":

Link.where("long_url like '%?'").count #=> 487185

	# display help
	Shortcutter.Keyboard.bindShortcut '?', 'Show/hide this help dialog', ->
	$('#keyboard-shortcuts-help').modal('toggle')
	false

	# focus on search
	Shortcutter.Keyboard.bindShortcut '/', 'Focus on the "Search" form at the top', ->

	#!/bin/bash -e
	PREV_PWD=`pwd`
	mkdir -p "$HOME/tmp"
	cd "$HOME/tmp"

	echo "-----> Cloning into $1"
	heroku git:clone -a $1
	cd $1
