charliepark / Using Rails to find values within a range
Created January 27, 2009 00:42
From Rails changeset 5876: http://dev.rubyonrails.org/changeset/5876
A range may be used in the hash to use the SQL BETWEEN operator:
Student.find(:all, :conditions => { :grade => 9..12 })
... so, presumably ...
User.find(:all, :conditions => { :created_at => '2009-01-01'..'2009-02-01' })
... compare with ...

Friendlier Error Messages
(from http://apidock.com/rails/ActionView/Helpers/ActiveRecordHelper/error_messages_for#82-Friendlier-error-message-example)
The default error messages can be a bit stale and off putting. Try somethings like this:
error_messages_for(
:user,
:header_message => "Oops - We couldn't save your user!",
:message => "The following fields were a bit of a problem:",
:header_tag => :h1

charliepark / jQuery - update an object's z-index based on the current time.
Created April 10, 2009 19:28
/*
A way to set your z-index to dynamically update, based on the current time.
When you click on the object ('.element'), the javascript grabs the current time,
concatenates the hours, minutes, and seconds, and sets that number as the z-index for the object.
*/
$('.element').mousedown(function(event) {
var time = new Date();
var hours = time.getHours();
if (hours.toString().length == 1) { hours = "0" + '' + hours }

charliepark / A Minimalist CSS Grid Framework
Created May 18, 2009 13:31
This is intended to be a minimalist alternative to Blueprint (www.blueprintcss.org) and other, more fleshed-out CSS grid frameworks. Change 3 variables, and the framework does the rest for you. It's intended for use in Ruby / Rails applications.
========
Put the following in the <head> of your ERB file (either in a layout file or in a partial, if you're calling it from several pages):
<style type="text/css">
.g{BACKGROUND:RGBA(255,0,0,0.2)}
<%
num = number_of_columns = 16
