Sass/Less Comparison

In this document I am using Sass's SCSS syntax. You can choose to use the indented syntax in sass, if you prefer it, it has no functional differences from the SCSS syntax.

For Less, I'm using the JavaScript version because this is what they suggest on the website. The ruby version may be different.

Validations

Data integrity is an underrated part of proper application architecture. Many of the bugs in production systems are triggered by missing or malformed user data. If a user can possibly screw it up or screw with it, they will. Validations in the model can help!

On Syntax

Before we begin, let's talk about syntax. There are two primary syntaxes for writing validations in Rails 3:

validates_presence_of :price

In this article, I'll walk through a basic Rails (3.2.x) setup for creating a nested resource for two models. Nested resources work well when you want to build out URL structure between two related models, and still maintain a RESTful convention. This code assumes you are running RVM to manage Ruby/Gem versions, and Git for version control.

Creating a new Rails project

$ mkdir family # create rvm gemset 
$ echo "rvm use --create ruby-1.9.2@family" > family/.rvmrc 
$ cd family # install rails 
$ gem install rails # create new rails project 
$ rails new . # version control

  # glyph(:lock, :white)
  # # => <i class="icon-lock icon-white"></i>

  def glyph(*names)
    content_tag :i, nil, class: names.map{|name| "icon-#{name.to_s.gsub('_','-')}" }
  end
