SMACSS principles SMACSS (Scalable and Modular Architecture for CSS) is a set of CSS guidelines created and promoted by Jonathan Snook, who also offers an e-book of the same name.

Asset Pipeline for Dummies - coderberry. The Rails asset pipeline is very powerful, but often misunderstood.

I admit that I was confused as well and took it’s magic for granted. Not any longer. I reference the word asset a lot in this article. In this article, I want to simplify the asset pipeline so it is better understood.
Purpose The asset pipeline has three goals: precompile, concatenate and minify assets into one central path. Moving Parts The asset pipeline is powered by two technologies: Sprockets and Tilt, the latter being a dependency of the former (look at your Gemfile.lock if you don’t believe me).

Tilt is the template engine that Sprockets uses. How to Create a Blog from Scratch Using Ruby on Rails. Ruby on rails - How can I display every 4th product with different markup. ActionView.

This means HTML tags will appear in the page but all malicious code will be removed. Let's look at some examples using the simple_format method: Links - link_to image_tag with text in rails. A Wealth Of Ruby Loops And Iterators. I remember when I first started looking at Ruby, I’d be browsing some code and see yet another way of looping/iterating over stuff.
Whenever that would happen I would think, “…Ruby sure has a lot of different ways to iterate over things”, but I also remember wishing that someone would just put all the different ways to loop and iterate over stuff together so that you don’t have to discover them in a piecemeal fashion. Most resources I’ve seen tend to gloss over this a little bit by introducing the while loop and the each iterator and quickly moving on to more interesting things, expecting you to discover the rest on your own (nothing wrong with that by the way). As you may have guessed from my recent posts on Ruby method arguments (and more advanced method arguments), the Ruby case statement and others, I am kind-of discovering Ruby in my own way and looking more closely at things that I find of interest.
