Relationship Semantics

The new relationship semantics change the current app/store/transaction/adapter APIs in several ways:

Changes to the Application API

At present, a record can be freely moved across transactions as long as it has no changes. Once a record accumulates at least one change, an application cannot move it out of its current transaction until the transaction is committed or rolled back.

Some random notes on the pangs of ember. Will be expanding as they are uncovered.

Building a form

Say you have a form that maps to a model, something like:

<form>
  <fieldset>
    <legend>Who are you?</legend>

A Common .ruby-version File For Ruby Projects

Background

I've been using this technique in most of my Ruby projects lately where Ruby versions are required:

Create .rbenv-version containing the target Ruby using a definition name defined in ruby-build (example below). These strings are a proper subset of RVM Ruby string names so far...
Create .rvmrc (with rvm --create --rvmrc "1.9.3@myapp") and edit the environment_id= line to fetch the Ruby version from .rbenv-version (example below).

Today I learned about another Ruby manager, rbfu, where the author is using a similar technique with .rbfu-version.

I have a state machine for the major sections of the page:

App.States = Ember.StateManger.create({
  foo: Ember.State.create({})
});

I have a view that needs to reset itself whenever the user enters the foo state:

	Ember.HandlebarsTransformView = Ember.View.extend(Ember._Metamorph, {
	rawValue: null,
	transformFunc: null,

	value: function(){
	var rawValue = this.get('rawValue'),
	transformFunc = this.get('transformFunc');
	return transformFunc(rawValue);
	}.property('rawValue', 'transformFunc').cacheable(),

	#Knife invocations supply FQDN as the node name at creation time and this becomes hostname( option -N)

	execute "Configure Hostname" do
	command "hostname --file /etc/hostname"
	action :nothing
	end

	#Ensure the hostname of the system is set to knife provided node name
	file "/etc/hostname" do
	content node.name

	require 'bundler/setup'
	require 'sass'
	require 'compass'
	require 'rake-pipeline'
	require 'listen'
	require 'rack/lock'
	require 'ruby-debug'
	require 'securerandom'

	STDOUT.sync = true

	input {
	stdin {
	type => rails
	}
	}

	filter {
	grok {
	type => "rails"
	pattern => "Completed %{GREEDYDATA:operation} in %{NUMBER:time:int}ms"
