Friendly URLs

By default, Rails applications build URLs based on the primary key -- the id column from the database. Imagine we have a Person model and associated controller. We have a person record for Bob Martin that has id number 6. The URL for his show page would be:

/people/6

But, for aesthetic or SEO purposes, we want Bob's name in the URL. The last segment, the 6 here, is called the "slug". Let's look at a few ways to implement better slugs.

Updated for Rails 4.0.0+

Bower

Set up the bower gem.
Follow the Bower instructions and list your dependencies in your bower.json, e.g.
```

{

Prerequisites

QNAP NAS
Supported USB sound card

"Solution"

First of all install Optware via the QPKG menu
Connect to your NAS (e.g. ssh admin@192.168.1.1)
Install various software packages with ipkg install xxx (mainly avahi, openssl, and various build tools - refer to my package list shown below)

Capybara Actions

# Anchor
click_link 'Save'

# Button
click_button 'awesome'

# Both above

	=Navigating=
	visit('/projects')
	visit(post_comments_path(post))

	=Clicking links and buttons=
	click_link('id-of-link')
	click_link('Link Text')
	click_button('Save')
	click('Link Text') # Click either a link or a button
	click('Button Value')

	class CreateRelatedUsers < ActiveRecord::Migration
	def change
	create_table :related_users, id: false do \|t\|
	t.integer :user_id
	t.integer :related_user_id
	end

	add_index(:related_users, [:user_id, :related_user_id], :unique => true)
	add_index(:related_users, [:related_user_id, :user_id], :unique => true)
	end

	This is a comparision of handling JavaScript alert/confirm/prompt notifications with Capybara.

	Proposed consolidated API in Capybara:

	There are two styles of notification handling: proactive or reactive.
	- Proactive is used in headless environments to queue up responses.
	- Reactive is used in environments with actual notifications that mandate a response (eg selenium).

	alert - # Reactive
	page.driver.accept_alert

	Add config/puma.ruby
	--------------------

	cd /home/redmine/redmine
	sudo -u redmine -H curl --output config/puma.rb https://gist.github.com/thanhhh/5610668/raw/fdfe2a865c3a0afe912c8784c971ea7ca3e64cfd/puma.rb

	Install Init Script
	--------------------
	Download the init script (will be /etc/init.d/redmine):

	#app/inputs/collection_check_boxes_input.rb
	class CollectionCheckBoxesInput < SimpleForm::Inputs::CollectionCheckBoxesInput
	def item_wrapper_class
	"checkbox-inline"
	end
	end

	#!/usr/bin/ruby
	# Create display override file to force Mac OS X to use RGB mode for Display
	# see http://embdev.net/topic/284710

	require 'base64'

	data=`ioreg -l -d0 -w 0 -r -c AppleDisplay`

	edids=data.scan(/IODisplayEDID.*?<([a-z0-9]+)>/i).flatten
	vendorids=data.scan(/DisplayVendorID.*?([0-9]+)/i).flatten
