#Setting up Nginx on Your Local System ###by Keith Rosenberg

##Step 1 - Homebrew The first thing to do, if you're on a Mac, is to install homebrew from http://mxcl.github.io/homebrew/

The command to type into terminal to install homebrew is:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Workflows (States) in Django

I'm going to cover a simple, but effective, utility for managing state and transitions (aka workflow). We often need to store the state (status) of a model and it should only be in one state at a time.

Common Software Uses

Publishing (Draft->Approved->Published->Expired->Deleted)

Alex's Rails Cheat Sheet

I think the most confusing thing that I have found about Ruby on Rails so far has been the transition from (trying to) write code myself to the use of the fabled "Rails Magic". So, to help my own understanding of a few core Ruby on Rails concepts, I have decided to write something on what I think is a CRITICAL topic... the idea of Convention over Configuration and why (in my mind) it is the most important thing that helps Rails become magic!

(This may be a topic that we cover in more detail in class but as I said, I'm writing this for my own understanding... I hope it helps someone else understand things too... Perhaps you can give me a hand when I'm crying next week!)

##Convention over configuration ###What does this "actually" mean...

Customize Save In Django Admin Inline Form

Background

This is a common case in django ORM.

from django.db import models

class Author(models.Model):

Install Homebrew

ruby -e "$(curl -fsSL https://raw.github.com/mxcl/homebrew/go)"

Add PATH to ~/.bash_profile and ~/.zshrc

export PATH=/usr/local/bin:$PATH

	# -- coding: utf-8 --

	from os import walk, sep
	from os.path import basename, isdir
	from sys import argv

	def tree(startpath, print_files=False):
	for root, subdirs, files in walk(startpath):
	level = root.replace(startpath, '').count(sep)
	indent = ' \|' * (level-1) + ' +- '

	Rails scaffolding types
	These types are valid since Rails version 2:

	string
	text (long text, up to 64k, often used for text areas)
	datetime
	date
	integer
	binary
	boolean

	/**
	* Get a random floating point number between `min` and `max`.
	*
	* @param {number} min - min number
	* @param {number} max - max number
	* @return {number} a random floating point number
	*/
	function getRandomFloat(min, max) {
	return Math.random() * (max - min) + min;
	}

	<%= render("shared/navbar") %>

	<div class="container">

	<%= render("shared/alerts") %>
	<%= render("shared/page_header") %>

	<%= yield %>

	<%= render("shared/footer") %>

	class LanguageMiddleware(object):
	"""
	Detect the user's browser language settings and activate the language.
	If the default language is not supported, try secondary options. If none of the
	user's languages are supported, then do nothing.

	def is_supported_language(self, language_code):
